hibernate +命名查詢未知

Question

我在使用帶有hibernate和spring的命名查詢時遇到了問題。

下面是我的代碼和stacktrace。

方法是調用我的查詢是：

@SuppressWarnings("unchecked") 
    @Override 
    public List<CampaignEntity> getCampaignList() {  
     final Query clientQuery = getNamedQuery(CampaignEntity.GET_CAMPAIGNS_QUERY); 
     return (List<CampaignEntity>) clientQuery.list(); 
    } 

我的實體類

package com.nativeunlock.dto; 

import java.io.Serializable; 

import javax.persistence.*; 

import lombok.Data; 
import lombok.Getter; 
import lombok.Setter; 


@SuppressWarnings("serial") 
@NamedQueries({ 
    @NamedQuery(
      name = CampaignEntity.GET_CAMPAIGNS_QUERY, 
      query = "from CampaignEntity campaign" 
    )  
}) 

@Entity 
@Data 
@Table(name = "campaign") 
public class CampaignEntity implements Serializable { 

    public static final String GET_CAMPAIGNS_QUERY ="getCampaignList"; 

    @Id 
    @Getter 
    @Setter 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    @Column(name = "campaingn_id", unique = true, nullable = false) 
    private int campain_id; 


    @Getter 
    @Setter 
    @Column(name = "no_of_views") 
    private int no_of_views; 


    @Getter 
    @Setter 
    @Column(name = "video_url") 
    private int video_url;  

}

任何人都可以幫我找出我在做什麼錯？

看來，你不掃描你在哪裏命名查詢所在，你掃描com.nativeunlock.dao.**

<property name="packagesToScan" value="com.nativeunlock.dao.**"/> 

，你是實體內com.nativeunlock.dto
