23日志

1、application.yml中配置连接数据库的信息

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/mp
    username: root
    password: "2000820."

2、创建实体类，和mapper接口

@Data
@AllArgsConstructor
@NoArgsConstructor
@TableName("tb_user")
public class User {
    private Integer id;
    private String username;
    private String password;
    private String name;
    private Integer age;
    private String email;
}

public interface UserMapper extends BaseMapper<User> {

}

3、配置mapper接口的扫描器

4、编写日志的配置信息

5、编写测试类
