2、实体类如下：

@Data
public class Person {
	private String pid;
	private String pname;
}

3、mapper类如下

public interface PersonMapper {
 @Select("select * from person")	
 List findPersonList();
}

4、service类如下

@Service
public class PersonService {
	@Autowired
	private PersonMapper personMapper;
	public PageInfo findPersonList(int page,int pageSize){
		PageHelper.startPage(page,pageSize);//底层实现原理改写语句
		List lists=personMapper.findPersonList();
		PageInfo pageInfoUserList=new PageInfo(lists);
		return pageInfoUserList;
	}
	
	
}

5、controller类如下

@RestController
public class PersonController {
	@Autowired
	private PersonService personService;
	
	@RequestMapping("index")
	public PageInfoindex(int page,int pageSize){
		return personService.findPersonList(page, pageSize);
	}
}

7、测试类如下

@SpringBootApplication  
@MapperScan("com.hlkj.mapper")
public class PagehelperTest {
	
	public static void main(String[] args) {
	    SpringApplication.run(PagehelperTest.class, args);
	}
}

8、application.properties如下

spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
