SSM整合案例（超详细）

环境准备

前提须知

在SSM整合的时候，我们是用Spring框架去整合SpringMVC框架和MyBatis框架。

创建数据库和表结构

create database ssm;
create table account(
id int primary key auto_increment,
name varchar(100),
money double(7,2),
);

创建 Maven 工程 ssm

目录结构：

导入坐标并建立依赖

MyBatis 和 Spring 的版本对应关系

编写实体类

Account：

package com.keafmd.domain;

import java.io.Serializable;

/**
 * Keafmd
 *
 * @ClassName: Account
 * @Description: 账户实体类
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 21:03
 */
public class Account implements Serializable {
     

    private Integer id;
    private String name;
    private Double money;

    public Integer getId() {
     
        return id;
    }

    public void setId(Integer id) {
     
        this.id = id;
    }

    public String getName() {
     
        return name;
    }

    public void setName(String name) {
     
        this.name = name;
    }

    public Double getMoney() {
     
        return money;
    }

    public void setMoney(Double money) {
     
        this.money = money;
    }

    @Override
    public String toString() {
     
        return "Account{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", money=" + money +
                '}';
    }
}

编写持久层接口

package com.keafmd.dao;

import com.keafmd.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * Keafmd
 *
 * @ClassName: AccountDao
 * @Description: 账户dao接口
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 21:05
 */
public interface AccountDao {
     

    //查询所有账户
    public List<Account> findAll();

    //保存账户
    public void saveAccount(Account account);

}

编写业务层接口

package com.keafmd.service;
import com.keafmd.domain.Account;
import java.util.List;

/**
 * Keafmd
 *
 * @ClassName: AccountService
 * @Description:
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 21:15
 */

public interface AccountService {
     

    //查询所有账户
    public List<Account> findAll();

    //保存账户
    public void saveAccount(Account account);

}

编写业务层实现类

package com.keafmd.service.impl;

import com.keafmd.dao.AccountDao;
import com.keafmd.domain.Account;
import com.keafmd.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * Keafmd
 *
 * @ClassName: AccountServiceImpl
 * @Description: 账户的业务层实现类
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 21:16
 */
public class AccountServiceImpl implements AccountService {
     

    @Override
    public List<Account> findAll() {
     
        System.out.println("业务层，查询所有。。。");
        return null;
    }

    @Override
    public void saveAccount(Account account) {
     
        System.out.println("业务层，保存账户。。。");
    }
}

编写 Controller

package com.keafmd.controller;

/**
 * Keafmd
 *
 * @ClassName: AccountController
 * @Description: 账户控制器 web
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 21:19
 */
public class AccountController {
     

}

整合步骤

保证 Spring 框架在 web 工程中独立运行

第一步：编写 spring 配置文件并导入约束

applicationContext.xml：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/aop
       http://www.springframework.org/schema/aop/spring-aop.xsd
       http://www.springframework.org/schema/tx
       http://www.springframework.org/schema/tx/spring-tx.xsd">

    
    <context:component-scan base-package="com.keafmd">
        
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    context:component-scan>

beans>

第二步：使用注解配置业务层

AccountServiceImpl：

package com.keafmd.service.impl;

import com.keafmd.dao.AccountDao;
import com.keafmd.domain.Account;
import com.keafmd.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * Keafmd
 *
 * @ClassName: AccountServiceImpl
 * @Description: 账户的业务层实现类
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 21:16
 */
@Service("accountService")
public class AccountServiceImpl implements AccountService {
     


    @Override
    public List<Account> findAll() {
     
        System.out.println("业务层，查询所有。。。");
        return null;
    }

    @Override
    public void saveAccount(Account account) {
     
        System.out.println("业务层，保存账户。。。");
    }
}

第三步：导入log4j.properties配置文件

# Set root category priority to INFO and its only appender to CONSOLE.
#log4j.rootCategory=INFO, CONSOLE            debug   info   warn error fatal
log4j.rootCategory=info, CONSOLE, LOGFILE

# Set the enterprise logger category to FATAL and its only appender to CONSOLE.
log4j.logger.org.apache.axis.enterprise=FATAL, CONSOLE

# CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

# LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=d:\axis.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d{ISO8601} %-6r [%15.15t] %-5p %30.30c %x - %m\n

第四步：测试 spring 能否独立运行

测试代码：

package com.keafmd.test;

import com.keafmd.service.AccountService;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * Keafmd
 *
 * @ClassName: TestSpring
 * @Description: 测试类
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 22:37
 */
public class TestSpring {
     

    @Test
    public void run1(){
     
        //加载配置文件
        ApplicationContext ac = new ClassPathXmlApplicationContext("classpath:applicationContext.xml");
        //获取对象
        AccountService as = (AccountService)ac.getBean("accountService");
        //调用方法
        as.findAll();

    }
}

运行结果：

业务层，查询所有。。。

Process finished with exit code 0

保证 SpringMVC 在 web 工程中独立运行

第一步：在 web.xml 中配置核心控制器（DispatcherServlet）

web.xml：

<web-app>
    <display-name>Archetype Created Web Applicationdisplay-name>

    
    <servlet>
        <servlet-name>dispatcherServletservlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
        
        <init-param>
            <param-name>contextConfigLocationparam-name>
            <param-value>classpath:springmvc.xmlparam-value>
        init-param>
        
        <load-on-startup>1load-on-startup>
    servlet>
    <servlet-mapping>
        <servlet-name>dispatcherServletservlet-name>
        <url-pattern>/url-pattern>
    servlet-mapping>

    
    <filter>
        <filter-name>characterEncodingFilterfilter-name>
        <filter-class>org.springframework.web.filter.CharacterEncodingFilterfilter-class>
        <init-param>
            <param-name>encodingparam-name>
            <param-value>UTF-8param-value>
        init-param>
    filter>
    <filter-mapping>
        <filter-name>characterEncodingFilterfilter-name>
        <url-pattern>/*url-pattern>
    filter-mapping>

web-app>

第二步：编写 SpringMVC 的配置文件

springmvc.xml：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation=" http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd">

    
    <context:component-scan base-package="com.keafmd">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    context:component-scan>
    
    <bean id="viewResolver"
          class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        
        <property name="prefix" value="/WEB-INF/pages/"/>
        
        <property name="suffix" value=".jsp"/>
    bean>

    
    <mvc:resources location="/css/" mapping="/css/**"/>
    <mvc:resources location="/images/" mapping="/images/**"/>
    <mvc:resources location="/js/" mapping="/js/**"/>

    
    <mvc:annotation-driven/>

beans>

第三步：编写 Controller 和 jsp 页面

index.jsp：

<%--
  Created by IntelliJ IDEA.
  User: Keafmd
  Date: 2021/2/17
  Time: 23:20
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>

    <a href="account/findAll">测试查询</a>

</body>
</html>

AccountController：

package com.keafmd.controller;

import com.keafmd.domain.Account;
import com.keafmd.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;

/**
 * Keafmd
 *
 * @ClassName: AccountController
 * @Description: 账户控制器 web
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 21:19
 */
@Controller
@RequestMapping("/account")
public class AccountController {
     

    /**
     * 查询所有
     * @param 
     * @return
     */
    @RequestMapping("/findAll")
    public String findAll(){
     
        System.out.println("表现层，查询所有账户信息。。。");
        return "list";
    }

}

list.jsp：

<%--
  Created by IntelliJ IDEA.
  User: Keafmd
  Date: 2021/2/18
  Time: 15:50
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>

    <h1>查询所有的账户</h1>

</body>
</html>

第四步：部署tomcat服务器

启动服务器，进行测试

控制台输出：

表现层，查询所有账户信息。。。

Spring 整合 SpringMVC 的框架

目的：在controller中能成功的调用service对象中的方法。

第一步：配置监听器实现启动服务创建容器

在web.xml添加监听器：

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
listener>

<context-param>
    <param-name>contextConfigLocationparam-name>
    <param-value>classpath:applicationContext.xmlparam-value>
context-param>

web.xml：

<web-app>
    <display-name>Archetype Created Web Applicationdisplay-name>

    
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
    listener>
    
    <context-param>
        <param-name>contextConfigLocationparam-name>
        <param-value>classpath:applicationContext.xmlparam-value>
    context-param>


    
    <servlet>
        <servlet-name>dispatcherServletservlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
        
        <init-param>
            <param-name>contextConfigLocationparam-name>
            <param-value>classpath:springmvc.xmlparam-value>
        init-param>
        
        <load-on-startup>1load-on-startup>
    servlet>
    <servlet-mapping>
        <servlet-name>dispatcherServletservlet-name>
        <url-pattern>/url-pattern>
    servlet-mapping>

第二步：在controller中注入service对象，调用service对象的方法进行测试

package com.keafmd.controller;

import com.keafmd.domain.Account;
import com.keafmd.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;

/**
 * Keafmd
 *
 * @ClassName: AccountController
 * @Description: 账户控制器 web
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 21:19
 */
@Controller
@RequestMapping("/account")
public class AccountController {
     

    @Autowired
    private AccountService accountService;

    /**
     * 查询所有
     * @return
     */
    @RequestMapping("/findAll")
    public String findAll(){
     
        System.out.println("表现层，查询所有账户信息。。。");
        //调用service的方法
        accountService.findAll();
        return "list";
    }
}

运行结果：
控制台输出：

表现层，查询所有账户信息。。。
业务层，查询所有。。。

保证 MyBatis 框架在 web 工程中独立运行

第一步：在web项目中编写SqlMapConfig.xml的配置文件，编写核心配置文件

SqlMapConfig.xml：

<configuration>
    
    <properties resource="jdbcConfig.properties">properties>
    
    <environments default="mysql">
        <environment id="mysql">
            
            <transactionManager type="JDBC">transactionManager>
            <dataSource type="pooled">
                <property name="driver" value="${jdbc.driver}"/>
                <property name="url" value="${jdbc.url}"/>
                <property name="username" value="${jdbc.username}"/>
                <property name="password" value="${jdbc.password}"/>
            dataSource>
        environment>
    environments>

    
    <mappers>
        
        <package name="com.keafmd.dao"/>
    mappers>
configuration>

jdbcConfig.properties：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm
jdbc.username=root
jdbc.password=root

第二步：在AccountDao接口的方法上添加注解，编写SQL语句

package com.keafmd.dao;

import com.keafmd.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * Keafmd
 *
 * @ClassName: AccountDao
 * @Description: 账户dao接口
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 21:05
 */
public interface AccountDao {
     

    //查询所有账户
    @Select("select * from account")
    public List<Account> findAll();

    //保存账户
    @Insert("insert into account(name,money) values(#{name},#{money})")
    public void saveAccount(Account account);

}

第三步：编写测试的方法

TestMybatis：

package com.keafmd.test;

import com.keafmd.dao.AccountDao;
import com.keafmd.domain.Account;
import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;

import java.io.InputStream;
import java.util.List;


/**
 * Keafmd
 *
 * @ClassName: TestMybatis
 * @Description: 测试Mybatis
 * @author: 牛哄哄的柯南
 * @date: 2021-02-18 16:37
 */
public class TestMybatis {
     

    private InputStream in;
    private SqlSessionFactory factory;
    private SqlSession session;
    private AccountDao accountDao;

    @Before
    public void init() throws Exception{
     
        //加载配置文件
        in = Resources.getResourceAsStream("SqlMapConfig.xml");
        //创建SqlSessionFactory对象
        factory = new SqlSessionFactoryBuilder().build(in);
        //创建SqlSession对象
        session = factory.openSession();
        //获取到代理对象
        accountDao = session.getMapper(AccountDao.class);
    }

    @After
    public void destory() throws Exception{
     
        session.commit();
        session.close();
        in.close();
    }

    /**
     * 查询所有
     */
    @Test
    public void run1(){
     
        List<Account> accounts = accountDao.findAll();
        for (Account account : accounts) {
     
            System.out.println(account);
        }
    }

    /**
     * 测试保存
     */
    @Test
    public void saveAccount(){
     
        Account account = new Account();
        account.setName("毛利小五郎");
        account.setMoney(800.00);
//        account.setMoney(800d);

        accountDao.saveAccount(account);
    }
}

运行run1()：

Account{
     id=1, name='keafmd', money=9000.0}
Account{
     id=2, name='小兰', money=8000.0}
Account{
     id=3, name='新一', money=8000.0}
Account{
     id=4, name='毛利小五郎', money=800.0}
Account{
     id=5, name='怪盗基德', money=660.0}
Account{
     id=6, name='某某', money=290.0}

Process finished with exit code 0

Spring 整合 MyBatis 框架

整合思路：把 mybatis 配置文件（SqlMapConfig.xml）中内容配置到 spring 配置文件中同时，把 mybatis 配置文件的内容清掉。

第一步：把SqlMapConfig.xml配置文件中的内容配置到applicationContext.xml配置文件中

把以下内容添加到applicationContext.xml配置文件中：

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <property name="driverClass" value="com.mysql.jdbc.Driver"/>
    <property name="jdbcUrl" value="jdbc:mysql:///ssm"/>
    <property name="user" value="root"/>
    <property name="password" value="root"/>
bean>

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
bean>

<bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.keafmd.dao"/>
bean>

SqlMapConfig.xml和jdbcConfig.properties可以删除了。

第二步：在applicationContext.xml配置文件中配置 spring 的事务

把以下内容添加到applicationContext.xml配置文件中：

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource">property>
bean>

<tx:advice id="txAdvice" transaction-manager="transactionManager">
    <tx:attributes>
        <tx:method name="find*" propagation="SUPPORTS" read-only="true"/>
        <tx:method name="*" isolation="DEFAULT"/>
    tx:attributes>
tx:advice>

<aop:config>
    
    
    <aop:pointcut expression="execution(* com.keafmd.service.impl.*.*(..))" id="pt1"/>
    
    <aop:advisor advice-ref="txAdvice" pointcut-ref="pt1"/>
aop:config>

applicationContext.xml：

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    context:component-scan>

    
    
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

    bean>
    
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
    bean>
    
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.keafmd.dao"/>
    bean>

    

    
    
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource">property>
    bean>
    
    <tx:advice id="txAdvice" transaction-manager="transactionManager">

        <aop:advisor advice-ref="txAdvice" pointcut-ref="pt1"/>
    aop:config>


beans>

第三步：在AccountDao接口中添加@Repository注解

AccountDao：

package com.keafmd.dao;

import com.keafmd.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * Keafmd
 *
 * @ClassName: AccountDao
 * @Description: 账户dao接口
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 21:05
 */
@Repository
public interface AccountDao {
     

    //查询所有账户
    @Select("select * from account")
    public List<Account> findAll();

    //保存账户
    @Insert("insert into account(name,money) values(#{name},#{money})")
    public void saveAccount(Account account);

}

第四步：在service中注入dao对象

AccountServiceImpl：

package com.keafmd.service.impl;

import com.keafmd.dao.AccountDao;
import com.keafmd.domain.Account;
import com.keafmd.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * Keafmd
 *
 * @ClassName: AccountServiceImpl
 * @Description: 账户的业务层实现类
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 21:16
 */
@Service("accountService")
public class AccountServiceImpl implements AccountService {
     

    @Autowired
    private AccountDao accountDao;

    @Override
    public List<Account> findAll() {
     
        System.out.println("业务层，查询所有。。。");
        return accountDao.findAll();
    }

    @Override
    public void saveAccount(Account account) {
     
        System.out.println("业务层，保存账户。。。");
        accountDao.saveAccount(account);
    }
}

第五步：修改 AccountController 代码

package com.keafmd.controller;

import com.keafmd.domain.Account;
import com.keafmd.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;

/**
 * Keafmd
 *
 * @ClassName: AccountController
 * @Description: 账户控制器 web
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 21:19
 */
@Controller
@RequestMapping("/account")
public class AccountController {
     

    @Autowired
    private AccountService accountService;

    /**
     * 查询所有
     * @param model
     * @return
     */
    @RequestMapping("/findAll")
    public String findAll(Model model){
     
        System.out.println("表现层，查询所有账户信息。。。");
        //调用service的方法
        List<Account> list = accountService.findAll();
        model.addAttribute("list",list);
        return "list";
    }

    /**
     * 保存
     * @param account
     * @param request
     * @param response
     * @throws IOException
     */
    @RequestMapping("/save")
    public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws IOException {
     
        accountService.saveAccount(account);
        response.sendRedirect(request.getContextPath()+"/account/findAll");
        return;
    }
}

第五步：修改 list.jsp 代码，实现显示账户信息

<%--

  User: Keafmd
  Date: 2021/2/18
  Time: 15:50
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
    <title>Title</title>
</head>
<body>

    <h1>查询所有的账户</h1>
    <%--${
     list}--%>

    <c:forEach items="${list}" var="account">
        ${
     account.name}
        ${
     account.money}
    </c:forEach>

</body>
</html>

第六步：测试查询

第七步：测试保存

修改index.jsp代码，添加测试保存的代码：

<%--
  Created by IntelliJ IDEA.
  User: Keafmd
  Date: 2021/2/17
  Time: 23:20
  To change this template use File | Settings | File Templates.
--%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>

    <a href="account/findAll">测试查询</a>

    <h1>测试保存</h1>
    <form action="account/save" method="post">
        姓名：<input type="text" name="name" /><br/>
        金额：<input type="text" name="money" /><br/>
        <input type="submit" value="保存">
    </form>

</body>
</html>

修改 AccountController 代码，添加save方法：

package com.keafmd.controller;

import com.keafmd.domain.Account;
import com.keafmd.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.List;

/**
 * Keafmd
 *
 * @ClassName: AccountController
 * @Description: 账户控制器 web
 * @author: 牛哄哄的柯南
 * @date: 2021-02-17 21:19
 */
@Controller
@RequestMapping("/account")
public class AccountController {
     

    @Autowired
    private AccountService accountService;

    /**
     * 查询所有
     * @param model
     * @return
     */
    @RequestMapping("/findAll")
    public String findAll(Model model){
     
        System.out.println("表现层，查询所有账户信息。。。");
        //调用service的方法
        List<Account> list = accountService.findAll();
        model.addAttribute("list",list);
        return "list";
    }

    /**
     * 保存
     * @param account
     * @param request
     * @param response
     * @throws IOException
     */
    @RequestMapping("/save")
    public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws IOException {
     
        accountService.saveAccount(account);
        response.sendRedirect(request.getContextPath()+"/account/findAll");
        return;
    }
}

测试结果：

以上就是SSM整合案例（超详细）的全部内容。
