2.15.5、测试乐观锁“修改”

• 测试后分析打印的sql语句，将version的数值进行了加1操作。 | package com.wzy.bootmtp.test;

import com.wzy.bootmtp.mapper.UserMapper;
import com.wzy.bootmtp.pojo.User;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.List;

@RunWith(SpringRunner.class)
@SpringBootTest
public class TestSpringBoot {

@Autowired<br />    **private **UserMapper **userMapper**;
@Test<br />    **public void **test1(){<br />        //查询<br />        User user = **userMapper**.selectById(1L);<br />        //修改数据<br />        user.setName(**"你好"**);<br />        user.setEmail(**"hello@qq.com"**);<br />        //执行更新<br />        **userMapper**.updateById(user);<br />    }<br />}
