logging:level:com.baomidou.mybatisplus.samples.quickstart: debug 3.数据库建表语句 DROP TABLE IF EXISTS user;CREATE TABLE user
(id BIGINT(20) NOT NULL COMMENT 主键ID,name VARCHAR(30) NULL DEFAULT NULL COMMENT 姓名,age INT(11) NULL DEFAULT NULL COMMENT 年龄,email VARCHAR(50) NULL DEFAULT NULL COMMENT 邮箱,PRIMARY KEY (id)
);DELETE FROM user;INSERT INTO user (id, name, age, email) VALUES
(1, Jone, 18, test1baomidou.com),
(2, Jack, 20, test2baomidou.com),
(3, Tom, 28, test3baomidou.com),
(4, Sandy, 21, test4baomidou.com),
(5, Billie, 24, test5baomidou.com); 4.编写实体类 User.java此处使用了 Lombok 简化代码 Data
public class User {private Long id;private String name;private Integer age;private String email;
} 5.编写Mapper类 UserMapper.java public interface UserMapper extends BaseMapperUser {} 6.添加测试类进行功能测试 RunWith(SpringRunner.class)
SpringBootTest
public class SampleTest {Autowiredprivate UserMapper userMapper;Testpublic void testSelect() {System.out.println((----- selectAll method test ------));ListUser userList userMapper.selectList(null);Assert.assertEquals(5, userList.size());userList.forEach(System.out::println);}} 测试结果如下: 转载于:https://www.cnblogs.com/charlypage/p/11148113.html
