功能比较简单！！！就下面几步就行

---

1.配置MyBatisConfiguration类

 

 

@Configuration
public class MyBatisConfiguration {
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor(){
               //构建mp拦截器对象
        MybatisPlusInterceptor plugs = new MybatisPlusInterceptor();
        //添加一个拦截器
        plugs.addInnerInterceptor(new PaginationInnerInterceptor());
        return plugs;
        }
}

 

2.配置controller层 service层 mapper层 

 #controller层

@RestController
@RequestMapping("/tcinfo")
public class TcinfosCtrl {
    @Resource
    private TcinfoStoreService tcinfoStoreService;

/**
 *4 塔机信息分页查询
 * @param page
 * @return
 */
@GetMapping(value ="/findTowerCrane")
public IPage find(@RequestParam(value ="page",required= false,defaultValue="1") Integer page){
    IPage result = tcinfoStoreService.findTc(page);
    return result;
}

}

# service层 接口

public interface TcinfoStoreService { 
   /**
     * 按照前端要去获取对应页上的塔吊信息数据
     * @param page 页码编号
     * @return
     */
    IPage findTc(Integer page);

}

# service层 实现类

@Service
public class TcinfoStoreServiceImpl implements TcinfoStoreService {
    @Resource
    private TCinfosMapper tCinfosMapper;

@Override
public IPage findTc(Integer page) {
    IPage ip= new Page<>(1,page);
    IPage result = tCinfosMapper.selectPage(ip, null);
    return result;
}

}

 

 

 

#mapper层

@Mapper
//使用mybatis-plus实现crud
public interface TCinfosMapper extends BaseMapper {
 
}

3.调用接口测试即可
