Maven 整合SSM步骤

项目整体布局

1. 整合说明：SSM整合可以使用多种方式，咱们会选择XML + 注解的方式
2. 整合的思路
   先搭建整合的环境
   先把Spring的配置搭建完成
   再使用Spring整合SpringMVC框架
   最后使用Spring整合MyBatis框架

1.创建数据库和表结构

create database ssm;
use ssm;
create table account(
id int primary key auto_increment,
name varchar(20),
money double
);

web依赖于service，service依赖于dao，dao依赖于domain

2.pom.xml文件中引入坐标依赖

      </plugins>
    </pluginManagement>
  </build>
</project>

3.在domain中编写实体类

package com.domain;

import java.io.Serializable;

/**
 * 帐户
 */
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 +
                '}';
    }
}

4.编写dao接口

package com.dao;

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

import java.util.List;

/**
 * 帐户dao接口
 */
@Repository
public interface AccountDao {
     

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

    // 保存帐户信息
    @Insert("insert into account (name,money) values (#{name},#{money})")
    public void saveAccount(Account account);

}

5.编写service接口和实现类

package com.service;

import com.domain.Account;

import java.util.List;

public interface AccountService {
     

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

    // 保存帐户信息
    public void saveAccount(Account account);

}

package com.service.impl;

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

import java.util.List;

@Service("accountService")
public class AccountServiceImpl implements AccountService {
     

    @Autowired
    private AccountDao accountDao;

    public List<Account> findAll() {
     
        System.out.println("业务层：查询所有账户...");
        return accountDao.findAll();
    }

    public void saveAccount(Account account) {
     
        System.out.println("业务层：保存帐户...");
        accountDao.saveAccount(account);
    }
}

6.创建applicationContext.xml的配置文件，编写具体的配置信息

<?xml version="1.0" encoding="UTF-8"?>
<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">

    <!--spring的配置文件-->
    <!--开启注解的扫描，希望处理service和dao，controller不需要Spring框架去处理-->
    <context:component-scan base-package="com" >
        <!--配置哪些注解不扫描-->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller" />
    </context:component-scan>

    <!--Spring整合MyBatis框架-->
    <!--配置连接池-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssm"/>
        <property name="user" value="root"/>
        <property name="password" value="root"/>
    </bean>

    <!--配置SqlSessionFactory工厂-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!--配置AccountDao接口所在包-->
    <bean id="mapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.dao"/>
    </bean>


    <!--配置Spring框架声明式事务管理-->
    <!--配置事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!--配置事务通知-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="find*" read-only="true"/>
            <tx:method name="*" isolation="DEFAULT"/>
        </tx:attributes>
    </tx:advice>

    <!--配置AOP增强-->
    <aop:config>
        <aop:advisor advice-ref="txAdvice"  pointcut="execution(* com.service.impl.*ServiceImpl.*(..))"/>
    </aop:config>

</beans>

7.在web.xml中配置springmvc相关的

<!DOCTYPE web-app PUBLIC
        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
        "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>

  <!--配置Spring的监听器，默认只加载WEB-INF目录下的applicationContext.xml配置文件-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!--设置配置文件的路径  加载spring的配置文件-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>


  <!--配置前端控制器-->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!--加载springmvc.xml配置文件-->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:springmvc.xml</param-value>
    </init-param>
    <!--启动服务器，创建该servlet-->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!--解决中文乱码的过滤器-->
  <filter>
    <filter-name>characterEncodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF-8</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>characterEncodingFilter</filter-name>
    <url-pattern>/*
  

8.创建springmvc.xml的配置文件，编写配置文件

<?xml version="1.0" encoding="UTF-8"?>
<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">

    <!--开启注解扫描，只扫描Controller注解-->
    <context:component-scan base-package="com">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
    </context:component-scan>

    <!--配置的视图解析器对象-->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/pages/"/>
        <property name="suffix" value=".jsp"/>
    </bean>## 标题

    <!--过滤静态资源-->
    <mvc:resources location="/css/" mapping="/css/**" />
    <mvc:resources location="/images/" mapping="/images/**" />
    <mvc:resources location="/js/" mapping="/js/**" />

    <!--开启SpringMVC注解的支持-->
    <mvc:annotation-driven/>

</beans>

9.编写index.jsp和list.jsp编写

index.jsp

<%--

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


</body>
</html>

10.创建AccountController类，编写方法

package com.controller;

import com.domain.Account;
import com.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;

/**
 * 帐户web  控制器
 */
@Controller
@RequestMapping("/account")
public class AccountController {
     
//    自动类型注入
    @Autowired
    private AccountService accountService;

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

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

}

11.加log4j.properties，日志文件

# 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

12.测试结果
