    <insert id="userRegister">
        insert into user(userName,userPwd) values(#{userName},#{userPwd})

spring的junit测试编写

package com.zl.mapper;

import com.zl.entity.Users;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import java.util.List;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:spring_config.xml"})
public class UserMapper {
    @Autowired
    UsersMapper usersMapper;

    @org.junit.Test
    public void myTest(){
        List<Users> users = usersMapper.queryUsersAll();
        for (Users user : users) {
            System.out.println(user);
        }
    }
}

注意：

  • 当使用lombok的时候，如果IDEA没有安装lombok插件就会报错
