JPA 以SQL实现分页不模糊查询(参数可能为空)

repository代码:

package com.fancy.miniflow.repository;

import java.util.List;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.JpaSpecificationExecutor;
import org.springframework.data.jpa.repository.Query;

import com.fancy.miniflow.entity.UploadRecord;

public interface UploadRecordRepository extends JpaRepository<UploadRecord, Integer>,JpaSpecificationExecutor<UploadRecord> {

　　@Query(nativeQuery = true , value = "SELECT * from upload_record "
　　　　+ "WHERE if(?1 !='',upload_time < ?1,1=1) AND if(?2 !='',upload_time > ?2,1=1) AND if(?3 !='',id = ?3,1=1) LIMIT ?4,?5")
　　List<UploadRecord> getList(String endTime , String startTime , Integer id , Integer p ,Integer pageSize );
}

service代码:

package com.fancy.miniflow.serviceimp;

import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.fancy.miniflow.entity.UploadRecord;
import com.fancy.miniflow.repository.UploadRecordRepository;

@Service
public class UploadRecordService {

@Autowired
private UploadRecordRepository uploadRecordRepository;

public List<UploadRecord> getUploadRecord(int page , int pageSize , String beginTime , String endTime , Integer id){
Integer p = (page - 1)*pageSize;
List<UploadRecord> list = uploadRecordRepository.getList(endTime, beginTime, id, p, pageSize);
return list;
}
}
