一、目录结构和注意事项

1.目录结构

2.注意事项

（1）data.html里面的Vue

（2）箭头函数

二、引入依赖

三、Account类

package com.william.domain;
/**
 * @author ：lijunxuan
 * @date ：Created in 2019/6/4  21:15
 * @description ：
 * @version: 1.0
 */
public class Account {
    private Integer id;
    private String name;
    private Float money;
    @Override
    public String toString() {
        return "Account{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", money=" + 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 Float getMoney() {
        return money;
    }
    public void setMoney(Float money) {
        this.money = money;
    }
}

四、AccountDao接口

package com.william.dao;
import com.william.domain.Account;
import java.util.List;
public interface AccountDao {
    /**
     * 查询所用用户信息
     * @return
     */
    public List<Account> findAll();
    /**
     *根据用户ID查询
     * @return
     */
    Account findById(Integer id);
    /**
     * 更新用户数据
     * @param account
     */
    void update(Account account);
    /**
     * 添加用户数据
     * @param account
     */
    void insert(Account account);
    /**
     * 删除用户信息
     * @param id
     */
    void delete(Integer id);
}

五、service

1.accountService接口

package com.william.service;
import com.william.domain.Account;
import org.springframework.stereotype.Service;
import java.util.List;
public interface AccountService {
    /**
     * 查询所用用户信息
     * @return
     */
    public List<Account> findAll();
    /**
     * 根据ID查询用户信息
     * @return
     */
    Account findById(Integer id);
    void update(Account account);
    void insert(Account account);
    void delete(Integer id);
}

2.AccountServiceImpl实现类

package com.william.service.Impl;
import com.william.dao.AccountDao;
import com.william.domain.Account;
import com.william.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
/**
 * @author ：lijunxuan
 * @date ：Created in 2019/6/4  21:21
 * @description ：
 * @version: 1.0
 */
@Service
public class AccountServiceImpl implements AccountService {
    @Autowired
    AccountDao accountDao;
    @Override
    public List<Account> findAll() {
        return accountDao.findAll();
    }
    @Override
    public Account findById(Integer id) {
        return accountDao.findById(id);
    }
    @Override
    public void update(Account account) {
        accountDao.update(account);
    }
    @Override
    public void insert(Account account) {
        accountDao.insert(account);
    }
    @Override
    public void delete(Integer id) {
        accountDao.delete(id);
    }
}

六、AccountDao.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.william.dao.AccountDao">
    <select id="findAll" resultType="account">
       select * from account
    </select>
    <select id="findById" parameterType="int" resultType="account">
        select * from account where id =#{id}
    </select>
    <update id="update" parameterType="account">
        update account set name=#{name},money=#{money} where id =#{id}
    </update>
    <insert id="insert" parameterType="account">
        insert into account values(null,#{name},#{money})
    </insert>
    <delete id="delete" parameterType="int">
        delete from account where id =#{id}
    </delete>
</mapper>

七、spring里的配置文件

目录结构

注意的细节

1.applicationContext-dao.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"
       xmlns:context="http://www.springframework.org/schema/context"
       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
      ">
    <!--开启注解扫描-->
    <context:component-scan base-package="com.william.service"></context:component-scan>
    <!--事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    <!--事务增强-->
    <tx:advice id="txadvice" transaction-manager="transactionManager">

            <tx:method name="*" />
        </tx:attributes>
    </tx:advice>
    <!--配置aop切面-->
   <aop:config>
       <aop:advisor advice-ref="txadvice" pointcut="execution(* com.william.service.Impl.*.*(..))"></aop:advisor>
   </aop:config>
</beans>

八、dp.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/web04
jdbc.user=root
jdbc.password=root

九、Spring-mvc.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"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--开启注解扫描-->
    <context:component-scan base-package="com.william.controller"></context:component-scan>
    <!--mvc注解驱动-->
    <mvc:annotation-driven></mvc:annotation-driven>
</beans>

十、web.xml

<!DOCTYPE web-app PUBLIC

    <servlet-name>DispatcherServlet</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
</web-app>

十一、AccountController

目录结构

@RequestBody注解

小细节

package com.william.controller;
import com.william.domain.Account;
import com.william.service.AccountService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;
/**
 * @author ：lijunxuan
 * @date ：Created in 2019/6/4  21:58
 * @description ：
 * @version: 1.0
 */
@RestController
@RequestMapping("/account")
public class AccountController {
@Autowired
    AccountService accountService;
            @RequestMapping("/findAll")
        public List<Account> findAll(){
                List<Account> accountList = accountService.findAll();
                return accountList;
            }
            @RequestMapping("/findById")
            public Account findById(Integer id){
             Account account =accountService.findById(id);
                return account;
            }
            @RequestMapping("/update")
    public String update(@RequestBody Account account){
                System.out.println(account);
                accountService.update(account);
                return "ok" ;
            }
            @RequestMapping("/insert")
            public String insert(@RequestBody Account account){
                System.out.println(account);
                accountService.insert(account);
                return "insert ok";
            }
            @RequestMapping("/delete")
            public String delete(Integer id){
                System.out.println(id);
                accountService.delete(id);
                return "delete success";
            }
}

十二、前端页面

1.需要引入的js

2.data.html页面

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <title>AdminLTE 2 | Data Tables</title>

  <meta content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" name="viewport">
  <link rel="stylesheet" href="../css/bootstrap.min.css">
  <script src="../js/jquery-1.9.1.js"></script>
  <script src="../js/bootstrap.min.js"></script>
</head>
<body class="hold-transition skin-blue sidebar-mini">
 <!-- Content Wrapper. Contains page content -->
  <div class="content-wrapper">

十三、功能实现步骤分解

1进入界面首先会加载页面查询所有用户信息

（1）在页面输入请求后进入data.html页面

（2）调用findAll向后端发送请求

（3） AccountController接收前端发送过来的请求

(4) 调用AccountServiceImpl实现类

（5）调用AccountDao

（6）AccountDao.xml映射文件查询数据

（7） 最后给前端相应数据
