            <artifactId>jstl</artifactId>
            <version>1.2</version>
        </dependency>

    </dependencies>

4、编写实体类

package com.xmp.domain;

public class Account {

    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;
    }
}

5、编写Mapper接口

package com.xmp.mapper;

import com.xmp.domain.Account;

import java.util.List;

public interface AccountMapper {

    public void save(Account account);

    public List<Account> findAll();

}

6、编写Service接口

package com.xmp.service;

import com.xmp.domain.Account;

import java.util.List;

public interface AccountService {

    public void save(Account account);

    public List<Account> findAll();

}

7、编写Service接口实现

package com.xmp.service.impl;

import com.xmp.domain.Account;
import com.xmp.mapper.AccountMapper;
import com.xmp.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 AccountMapper accountMapper;

    @Override
    public void save(Account account) {
        accountMapper.save(account);
    }

    @Override
    public List<Account> findAll() {
        return accountMapper.findAll();
    }
}

8、编写Controller

package com.xmp.controller;

import com.xmp.domain.Account;
import com.xmp.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;

import java.util.List;

@Controller
@RequestMapping("/account")
public class AccountController {

    @Autowired
    private AccountService accountService;

    //保存
    @RequestMapping(value = "/save",produces = "text/html;charset=UTF-8")
    @ResponseBody
    public String save(Account account){
        accountService.save(account);
        return "保存成功";
    }

    //查询
    @RequestMapping("/findAll")
    public ModelAndView findAll(){
        List<Account> accountList = accountService.findAll();
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.addObject("accountList",accountList);
        modelAndView.setViewName("accountList");
        return modelAndView;
    }

}

9、编写添加页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <h1>添加账户信息表单</h1>
    <form name="accountForm" action="${pageContext.request.contextPath}/account/save" method="post">
        账户名称:<input type="text" name="name"><br>
        账户金额:<input type="text" name="money"><br>
        <input type="submit" value="保存"><br>
    </form>
</body>
</html>

10、编写列表页面

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
    <h1>展示账户数据列表</h1>
    <table border="1">
        <tr>
            <th>账户id</th>
            <th>账户名称</th>
            <th>账户金额</th>
        </tr>

        <c:forEach items="${accountList}" var="account">
            <tr>
                <td>${account.id}</td>
                <td>${account.name}</td>
                <td>${account.money}</td>
            </tr>
        </c:forEach>

    </table>
</body>
</html>

11、编写相应配置文件

  • Spring配置文件：applicationContext.xml

    <?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

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

</beans>
