Question

我正在使用jpa连接到mysql。当我使用查询到表数据库时：

public interface CommentRepository  extends JpaRepository<Comment1, Integer>{
	@Query(value = "SELECT * FROM comment1 WHERE contribution_id=:contributionId",nativeQuery = true)
	List<Comment1> findByContributionId(@Param("contributionId") String contributionId);
}

package com.example;

import java.io.Serializable;
import java.sql.Timestamp;
import java.util.List;

import javax.annotation.Generated;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.OneToMany;

/**
 * Comment1エンティティクラス
 *
 */
@Entity
public class Comment1 implements Serializable {

	private static final long serialVersionUID = 1L;

	/** commentIdプロパティ */
	@Id
	@GeneratedValue(strategy = GenerationType.IDENTITY)
	@Column(name = "comment_id", precision = 11, nullable = false, unique = true)
	public Integer commentId;

	/** contributionIdプロパティ */
	@Column(name = "contribution_id", precision = 20, nullable = false, unique = false)
	public Integer contributionId;

	/** userIdプロパティ */
	@Column(precision = 11, nullable = false, unique = false)
	public Integer userId;

	/** commentプロパティ */
	@Column(length = 2000, nullable = true, unique = false)
	public String comment;

	/** photoIdプロパティ */
	@Column(precision = 11, nullable = true, unique = true)
	public Integer photoId;

	/** stampIdプロパティ */
	@Column(precision = 11, nullable = true, unique = true)
	public Integer stampId;

	/** likeCountプロパティ */
	@Column(precision = 11, nullable = false, unique = false)
	public Integer likeCount;

	/** updateDateプロパティ */
	@Column(nullable = true, unique = false)
	public Timestamp updateDate;

	/** createDateプロパティ */
	@Column(nullable = false, unique = false)
	public Timestamp createDate;

	/** deleteFlgプロパティ */
	@Column(precision = 11, nullable = false, unique = false)
	public Integer deleteFlg;

	// public List<Stamp1> stamp1List;

	/** stampPlaceプロパティ */
	@Column(precision = 11, nullable = false, unique = false)
	public Integer stampPlace;

}

我的控制器交易

package com.example;

import java.util.List;

import javax.transaction.Transactional;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;


@Service
@Transactional
public class ServiceComment {
	@Autowired
	CommentRepository commentRepository;
	
	public String findByFb(String contributionId){
		List<Comment1> datas = commentRepository.findByContributionId(contributionId);
		if (datas.size() != 0){
			Comment1 data = datas.get(0);
			return "found " + datas.size()+ "recore";
			
		}else  return "not found recore"; 
		
	}
}

我的问题是：当前我的数据库表“Comment1”存在500行的数据。 colume“contribution_id”的值为1到2235659。 - 当我从值contrib_id查询1到918时 - ＆gt;查询成功 - 当我从919到2235659进行查询时，虽然它存在于表中，但它找不到任何行。我认为它与配置限制查询或任何问题有关请帮我解决这个问题非常感谢!!

更新：我检查更多时间并找到与colume create_date相关的原因如果创建日期＆gt; 2015-06-24 15:47:52它无法查询真实。
