test数据库的user表在运行前状态：

通过 junit进行插入3条记录：

import org.junit.Test;

import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest(classes = {Application.class})
public class UserMapperTest extends BaseTest{
    @Autowired
    private UserMapper userMapper;
    @Test
    public void testInsert() {
        try {
            userMapper.insert(new User("man1", "男", 26));
            userMapper.insert(new User("man2", "男", 23));
            userMapper.insert(new User("man2", "男", 27));
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    @Test
    public void testUpdate() {
        try {
            User user = new User("测试0000", "男", 23);
            user.setId(11l);
            userMapper.update(user);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    @Test
    public void testQuery() {
        try {

    }
    @Test
    public void testDelete(){

            testQuery();
        } catch (Exception e) {

            e.printStackTrace();
        }

    }
}

测试update

测试 query all

测试delete

最后，启动spring boot
测试Controller

测试成功！
