pom.xml

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

3、编写数据库

SET FOREIGN_KEY_CHECKS=0;
-- ----------------------------
-- Table structure for account
-- ----------------------------
DROP TABLE IF EXISTS `account`;
CREATE TABLE `account` (
  `id` int NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL,
  `money` double DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;

4、编写实体类

Account

package com.ljx.domain;
/**
 * @Author: Ljx
 * @Date: 2021/8/23 14:06
 */
public class Account {
    private int id;
    private String name;
    private double money;
    public int getId() {
        return id;
    }
    public void setId(int 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 +
                '}';
    }
}

5、编写持久层接口

AccountMapper

package com.ljx.mapper;
import com.ljx.domain.Account;
import java.util.List;
/**
 * @Author: Ljx
 * @Date: 2021/8/23 14:08
 */
public interface AccountMapper {
    void save(Account account);
    List<Account> findAll();
}

6、编写业务层接口

AccountService

package com.ljx.service;
import com.ljx.domain.Account;
import java.io.IOException;
import java.util.List;
/**
 * @Author: Ljx
 * @Date: 2021/8/23 14:10
 */
public interface AccountService {
    void save(Account account) throws IOException;
    List<Account> findAll() throws IOException;
}

7、编写业务层实现类

AccountServiceImpl

package com.ljx.service.impl;
import com.ljx.domain.Account;
import com.ljx.mapper.AccountMapper;
import com.ljx.service.AccountService;
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.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.io.IOException;
import java.io.InputStream;
import java.util.List;
/**
 * @Author: Ljx
 * @Date: 2021/8/23 14:11
 */
@Service("accountService")
public class AccountServiceImpl implements AccountService {
    @Autowired
    private AccountMapper accountMapper;
    @Override
    public void save(Account account) throws IOException {
        InputStream resourceAsStream = Resources.getResourceAsStream("sqlMapConfig.xml");
        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(resourceAsStream);
        SqlSession sqlSession = sqlSessionFactory.openSession();
        AccountMapper mapper = sqlSession.getMapper(AccountMapper.class);
        mapper.save(account);
        sqlSession.commit();
        sqlSession.close();
    }
    @Override
    public List<Account> findAll() throws IOException {
        return accountMapper.findAll();
    }
}

8、编写 Controller

AccountController

package com.ljx.controller;
import com.ljx.domain.Account;
import com.ljx.service.AccountService;
import com.ljx.service.impl.AccountServiceImpl;
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.io.IOException;
import java.util.List;
/**
 * @Author: Ljx
 * @Date: 2021/8/23 14:13
 */
@Controller
@RequestMapping("/account")
public class AccountController {
    @Autowired
    private AccountService accountService;
    /**
     * 保存
     * @param account
     * @return
     */
    @RequestMapping(value = "/save", produces = "text/html;charset=UTF-8")
    @ResponseBody
    public String save(Account account) throws IOException {
        accountService.save(account);
        return "保存成功";
    }
    /**
     * 查询
     * @return
     */
    @RequestMapping("/findAll")
    public ModelAndView findAll() throws IOException {
        List<Account> accountList = accountService.findAll();
        ModelAndView modelAndView = new ModelAndView();
        modelAndView.addObject("accountList",accountList);
        modelAndView.setViewName("accountList");
        return modelAndView;
    }
}

9、编写配置文件

AccountMapper.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.ljx.mapper.AccountMapper">
    <insert id="save" parameterType="account">
        insert into account values (#{id},#{name},#{money})
    </insert>
    <select id="findAll" resultType="account">
        select * from account
    </select>
</mapper>
