一、搭建环境
1、创建数据库表和表结构
create table account(
id INT identity(1,1) primary key,
name varchar(20),
[money] DECIMAL
)
2、创建maven的工程SSM，在pom.xml文件引入依赖

3、部署ssm_web的项目，只要把ssm_web项目加java培训入到tomcat服务器中即可
4、编写实体类
package com.mingqi.domain;
import java.io.Serializable;
public class Account implements Serializable {
public void setId(Integer id) {
this.id = id;
}
public void setName(String name) {
this.name = name;
}
public void setMoney(Double money) {
this.money = money;
}
public Integer getId() {
return id;
}
public String getName() {
return name;
}
public Double getMoney() {
return money;
}
private Integer id;
private String name;
private Double money;
@Override
public String toString() {
return "Account{" +
"id=" + id +
", name='" + name + '\'' +
", money=" + money +
'}';
}}
5、编写dao接口
package com.mingqi.dao;
import com.mingqi.domain.Account;
import org.apache.ibatis.annotations.Insert;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository
public interface IAccountDao {
@Insert(value="insert into account (name,money) values (#{name},#{money})")
public void saveAccount(Account account);
@Select("select * from account")
public List findAll(); }6、编写service接口和实现类
package com.mingqi.service;
import com.mingqi.domain.Account;
import java.util.List;
public interface IAccountService {
public void saveAccount(Account account);
public List findAll(); }package com.mingqi.service.impl;
import com.mingqi.dao.IAccountDao;
import com.mingqi.domain.Account;
import com.mingqi.service.IAccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
@Service("accountService")
public class AccountImpl implements IAccountService {
@Autowired
private IAccountDao accountDao;
@Override
public void saveAccount(Account account) {
accountDao.saveAccount(account);
}
@Override
public List findAll() {
System.out.println("业务层：查询所有账户...");
List accounts=accountDao.findAll();
return accounts;
//return null;
} }
二、Spring框架代码的编写
搭建和测试Spring的开发环境
在webapp项目中创建applicationContext.xml的配置文件，编写具体的配置信息。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/beanshttp://www.springframework.or...
http://www.springframework.or...
http://www.springframework.or...
http://www.springframework.or...
http://www.springframework.or...
http://www.springframework.or...
http://www.springframework.or...d">
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
三、Spring整合SpringMVC框架
1、搭建和测试SpringMVC的开发环境在web.xml中配置DispatcherServlet前端控制器
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" >
org.springframework.web.context.ContextLoaderListener
contextConfigLocation
classpath:applicationContext.xml
dispatcherServlet
org.springframework.web.servlet.DispatcherServlet
contextConfigLocation
classpath:springmvc.xml
1
dispatcherServlet
/
characterEncodingFilter
org.springframework.web.filter.CharacterEncodingFilter
encoding
UTF-8
characterEncodingFilter
/*
2、测试SpringMVC的框架搭建是否成功
- 编写index.jsp和list.jsp编写，超链接
<%@ page contentType="text/html;charset=UTF-8" language="java" %>查询所有!
查询所有
测试查询测试包
<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
Title 查询所有的帐户
${account.name}2、创建AccountController类，编写方法，进行测试
package com.mingqi.controller;
import com.mingqi.domain.Account;
import com.mingqi.service.IAccountService;
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;
@Controller
@RequestMapping("/account")
public class AccountController {
@Autowired
private IAccountService accountService;
/**
* 查询所有数据
* @return
*/
@RequestMapping("/findAll")
public String findAll(Model model)
{
System.out.println("表现层查询所有");
accountService.findAll();
List list = accountService.findAll();
model.addAttribute("list",list);
return "list";
}
@RequestMapping("/save")
public void save(Account account, HttpServletRequest request, HttpServletResponse response) throws IOException
{
accountService.saveAccount(account);
response.sendRedirect(request.getContextPath()+"/account/findAll");
return;
} }
配置tomcat，启动项目，进行测试
