一、导入依赖：Mybatis-Plus的依赖

<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-boot-starter</artifactId>
    <version>3.1.2</version>
</dependency>

二、创建实体类

@Data
@AllArgsConstructor
@NoArgsConstructor
@ToString

@TableName(value = "department")
public class Department {
    @TableId(value = "dept_id",type = IdType.AUTO)
    private Integer depId;

    @TableField("dept_name")
    private String depName;

    @TableField("dept_phone")
    private String depPhone;

    @TableField("dept_status")
    private String depStatus;

    @TableField("dept_create_time")
    private Date createTime;
}

三、创建mapper

public interface DepartmentMapper extends BaseMapper<Department> {
}

四、配置mapper扫描

@SpringBootApplication
@MapperScan("com.example.mp.mapper")
public class MpApplication {

    public static void main(String[] args) {
        SpringApplication.run(MpApplication.class, args);
    }
}

或在mapper上加入@Mapper注解

@Mapper
public interface DepartmentMapper extends BaseMapper<Department> {
}

五、配置application.yml

server:
  servlet:
    context-path: /mp
  port: 8080
spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/alipay?serverTimezone=UTC
    username: root
    password: 123456
