一.创建项目

二.配置项目

MyBatis-Plus（简称 MP）是一个 MyBatis 的增强工具，在 MyBatis 的基础上只做增强不做改变，为简化开发、提高效率而生。

1.  pom.xml注入MP,p6spy依赖

<dependency>
                <groupId>com.baomidou</groupId>
                <artifactId>mybatis-plus-boot-starter</artifactId>
                <version>3.2.0</version>
            </dependency>
            
            <dependency>
                <groupId>p6spy</groupId>
                <artifactId>p6spy</artifactId>
                <version>3.8.5</version>
            </dependency>

1.  添加 / 配置application.yml  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDk3Nzk1MA_size_16_color_FFFFFF_t_70 4]

spring:
      datasource:
        driver-class-name: com.p6spy.engine.spy.P6SpyDriver
        url: jdbc:p6spy:mysql://localhost:3306/shop?serverTimezone=Asia/ShanghaiuseSSL=false&serverTimezone=GMT%2B8
        username: root
        password: root
    server:
      port: 8888
      servlet:
        context-path: /zdnl

1.  创建实体类

@Data
    @TableName("user")
    public class User {
    //默认为雪花命名
      private Long id;
      private String name;
      private Gender gender;
    }

1.  创建Mapper接口

public interface UserMapper extends BaseMapper<User> {}

1.  创建测试类,打测试注解

@RunWith(SpringRunner.class)
    @SpringBootTest
    public class UserMapperTest {
    @Autowired
        UserMapper userMapper;
        }
