Spring整合MyBatis

1.创建工程

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

 1.3applicationContext.xml

 2.配置数据源

2.1db.properties

这里是navicat版本5.0以上的配置

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/spring?useUnicode=true&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=1111

这里是navicat版本8.0以上的配置

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/spring?useSSL=false&serverTimezone=Asia/Shanghai
jdbc.username=root
jdbc.password=123456

2.2applicationContext.xml

 3.整合MyBatis

3.1applicationContext.xml

 4.测试

 4.1创建spring表

CREATE TABLE `t_user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) DEFAULT NULL,
  `money` float DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=14 DEFAULT CHARSET=utf8;

 4.2pojo

package com.by.pojo;

public class User {
    private Integer id;
    private String name;
    private Float money;

    public User(String name, Float money) {
        this.name = name;
        this.money = money;
    }

    public User() {
    }

    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;
    }
}

 4.3mapper

public interface UserMapper {
    public void addUser(User user);
}

 mapper.xml

    
        insert into t_user(name,money) values(#{name},#{money})
    

4.4service

package com.by.service;

import com.by.mapper.UserMapper;
import com.by.pojo.User;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

@Service
public class UserServiceImpl implements UserService{

    @Autowired
    private UserMapper userMapper;

    @Override
    public void addUser(User user){
        userMapper.addUser(user);
    }
}

 4.5junit

package com.by.web;

import com.by.pojo.User;
import com.by.service.UserService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)//加载配置文件
@ContextConfiguration("classpath:applicationContext.xml")
public class Client {

@Autowired
    private UserService userService;

@Test
    public void addUser(){
   userService.addUser(new User("小龙女",4000F));
   userService.addUser(new User ("李莫愁",2000F));
}

}
