Spring boot 使用三个实体中的方法公共抽象的查询的Spring引导联接查询验证失败

我用的是弹簧靴。我曾经加入三个实体来获取存储库中的数据，但它显示了下面的错误

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'menuRightRepo': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Validation failed for query for method public abstract java.util.List...  

Caused by: java.lang.IllegalArgumentException: Validation failed for query for method public abstract java.util.List

我使用了下面的代码

我的第一个实体名为MenuNameEntity如下

@Entity
@Table(name = "MenuName")
public class MenuNameEntity {
 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id;

 private String parentId;
 private String menuName;
 private String status;
 // getter and setter
 }

@Entity
@Table(name = "MenuChild")
public class MenuChildEntity {

 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id;   
 private String parentId;   
 private String childMenuName;  
 private String url;    
 private String status;
 //getter and setter
}

@Entity
@Table(name = "MenuRight")
public class MenuRightEntity {
  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  @Column(name = "id")
  private long id;

  private String companyId; 
  private String userId;    
  private String url;   
  private String status;    
  private String enqMode;   
  private String insertMode;    
  private String updateMode;    
  private String deleteMode;
 //getter and setter
 }

 public interface MenuRightRepo extends JpaRepository<MenuRightEntity, Long> {

  @Query("select new com.rms.info.MenuRightResponse(m.companyId, m.userId,m.enqMode,m.insertMode,m.updateMode,m.deleteMode, p.parentId,c.childId,c.childMenuName,c.url) from MenuNameEntity p,MenuChildEntity c,MenuRightEntity m where p.parentId = c.parentId  and p.status =1 and c.status =1 and c.url= m.url ")
 List<MenuRightResponse> getMenuMenuRights();   

}

我的第二个实体是贝娄

@Entity
@Table(name = "MenuName")
public class MenuNameEntity {
 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id;

 private String parentId;
 private String menuName;
 private String status;
 // getter and setter
 }

@Entity
@Table(name = "MenuChild")
public class MenuChildEntity {

 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id;   
 private String parentId;   
 private String childMenuName;  
 private String url;    
 private String status;
 //getter and setter
}

@Entity
@Table(name = "MenuRight")
public class MenuRightEntity {
  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  @Column(name = "id")
  private long id;

  private String companyId; 
  private String userId;    
  private String url;   
  private String status;    
  private String enqMode;   
  private String insertMode;    
  private String updateMode;    
  private String deleteMode;
 //getter and setter
 }

 public interface MenuRightRepo extends JpaRepository<MenuRightEntity, Long> {

  @Query("select new com.rms.info.MenuRightResponse(m.companyId, m.userId,m.enqMode,m.insertMode,m.updateMode,m.deleteMode, p.parentId,c.childId,c.childMenuName,c.url) from MenuNameEntity p,MenuChildEntity c,MenuRightEntity m where p.parentId = c.parentId  and p.status =1 and c.status =1 and c.url= m.url ")
 List<MenuRightResponse> getMenuMenuRights();   

}

我的第三个实体是贝娄

@Entity
@Table(name = "MenuName")
public class MenuNameEntity {
 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id;

 private String parentId;
 private String menuName;
 private String status;
 // getter and setter
 }

@Entity
@Table(name = "MenuChild")
public class MenuChildEntity {

 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id;   
 private String parentId;   
 private String childMenuName;  
 private String url;    
 private String status;
 //getter and setter
}

@Entity
@Table(name = "MenuRight")
public class MenuRightEntity {
  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  @Column(name = "id")
  private long id;

  private String companyId; 
  private String userId;    
  private String url;   
  private String status;    
  private String enqMode;   
  private String insertMode;    
  private String updateMode;    
  private String deleteMode;
 //getter and setter
 }

 public interface MenuRightRepo extends JpaRepository<MenuRightEntity, Long> {

  @Query("select new com.rms.info.MenuRightResponse(m.companyId, m.userId,m.enqMode,m.insertMode,m.updateMode,m.deleteMode, p.parentId,c.childId,c.childMenuName,c.url) from MenuNameEntity p,MenuChildEntity c,MenuRightEntity m where p.parentId = c.parentId  and p.status =1 and c.status =1 and c.url= m.url ")
 List<MenuRightResponse> getMenuMenuRights();   

}

我的菜单如下

@Entity
@Table(name = "MenuName")
public class MenuNameEntity {
 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id;

 private String parentId;
 private String menuName;
 private String status;
 // getter and setter
 }

@Entity
@Table(name = "MenuChild")
public class MenuChildEntity {

 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id;   
 private String parentId;   
 private String childMenuName;  
 private String url;    
 private String status;
 //getter and setter
}

@Entity
@Table(name = "MenuRight")
public class MenuRightEntity {
  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  @Column(name = "id")
  private long id;

  private String companyId; 
  private String userId;    
  private String url;   
  private String status;    
  private String enqMode;   
  private String insertMode;    
  private String updateMode;    
  private String deleteMode;
 //getter and setter
 }

 public interface MenuRightRepo extends JpaRepository<MenuRightEntity, Long> {

  @Query("select new com.rms.info.MenuRightResponse(m.companyId, m.userId,m.enqMode,m.insertMode,m.updateMode,m.deleteMode, p.parentId,c.childId,c.childMenuName,c.url) from MenuNameEntity p,MenuChildEntity c,MenuRightEntity m where p.parentId = c.parentId  and p.status =1 and c.status =1 and c.url= m.url ")
 List<MenuRightResponse> getMenuMenuRights();   

}

---

当我在MenuRightRepo中调用GetMenuRights（）时，它显示了上述错误。我没有使用任何主键和外键。代码有什么问题。请帮帮我，我已经解决了下面的问题，比如

我已将我的菜单更改为

@Entity
@Table(name = "MenuName")
public class MenuNameEntity {

 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id;

private String parentId;
private String menuName;
private String status;

 @OneToMany(fetch = FetchType.LAZY, mappedBy = "MenuName")  
 private Set<MenuChildEntity> menuChildEntities;

// getter and setter
}

@Entity
@Table(name = "MenuChild")
public class MenuChildEntity {

 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id; 

 @Column(name = "parentId", nullable = false,insertable = false,updatable = false) 
 private String parentId;   
 private String childMenuName;  
 private String url;    
 private String status;

 @OneToMany(fetch = FetchType.LAZY, mappedBy = "MenuChild") 
 private Set<MenuRightEntity> menuRightEntities;

 @ManyToOne
 @JoinColumn(name = "parentId")
 private MenuNameEntity MenuName;

 //getter and setter
 }

@Entity
@Table(name = "MenuRight")
public class MenuRightEntity {
  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id;

 private String companyId; 
 private String userId;  

@Column(name = "url", nullable = false,insertable = false,updatable = false)  
 private String url;   
 private String status;    
 private String enqMode;   
 private String insertMode;    
 private String updateMode;    
 private String deleteMode;        

 @ManyToOne
 @JoinColumn(name = "url")
 private MenuChildEntity MenuChild;

  //getter and setter

 }

---

然后，我的存储库查询工作正常…我只需将三个表无条件地连接到一对多&多对一，并将列连接到可为null的false，工作正常

我已经解决了以下问题：

我已将我的菜单更改为

@Entity
@Table(name = "MenuName")
public class MenuNameEntity {

 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id;

private String parentId;
private String menuName;
private String status;

 @OneToMany(fetch = FetchType.LAZY, mappedBy = "MenuName")  
 private Set<MenuChildEntity> menuChildEntities;

// getter and setter
}

@Entity
@Table(name = "MenuChild")
public class MenuChildEntity {

 @Id
 @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id; 

 @Column(name = "parentId", nullable = false,insertable = false,updatable = false) 
 private String parentId;   
 private String childMenuName;  
 private String url;    
 private String status;

 @OneToMany(fetch = FetchType.LAZY, mappedBy = "MenuChild") 
 private Set<MenuRightEntity> menuRightEntities;

 @ManyToOne
 @JoinColumn(name = "parentId")
 private MenuNameEntity MenuName;

 //getter and setter
 }

@Entity
@Table(name = "MenuRight")
public class MenuRightEntity {
  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
 @Column(name = "id")
 private long id;

 private String companyId; 
 private String userId;  

@Column(name = "url", nullable = false,insertable = false,updatable = false)  
 private String url;   
 private String status;    
 private String enqMode;   
 private String insertMode;    
 private String updateMode;    
 private String deleteMode;        

 @ManyToOne
 @JoinColumn(name = "url")
 private MenuChildEntity MenuChild;

  //getter and setter

 }

然后，我的存储库查询就可以正常工作了……我只是无条件地联接三个表一对多&多对一，并联接正常工作的列可为null的false

选择新的com.rms.info。。。。。？？？这应该是sql，而不是java代码。如果你想使用纯JPA，你必须定义你的实体。不使用连接定义实体，您就可以使用SpringJDBC对映射的支持capabilities@Alexander.Furer我也尝试过@Query（值=“从MenuName p、MenuChild c、MenuRight m中选择m.companyId、m.userId、m.enqMode、m.insertMode、m.updateMode、m.deleteMode、p.parentId、c.childId、c.childMenuName、c.url，其中p.parentId=c.parentId和p.status=1，c.status=1和c.url=m.url”，nativeQuery=true）列表GetMenuRights（）；此选择的结果集未映射到您的实体。您应该使用jdbc模板和映射manually@Alexander.Furer我需要在hibernate中显示上面查询中的值，如何使用three entity？@Alexander.furr我已经按照下面的命令选择new com.rms.info…？？这应该是sql，而不是java代码。如果你想使用纯JPA，您必须定义实体。如果不使用连接定义实体，您可以使用spring jdbc支持和映射capabilities@Alexander.Furer我也尝试过@Query（value=”从MenuName p、MenuChild c、MenuRight m中选择m.companyId、m.userId、m.enqMode、m.insertMode、m.updateMode、m.deleteMode、p.parentId、c.childId、c.childMenuName、c.url，其中p.parentId=c.parentId和p.status=1和c.url=m.url”，nativeQuery=true）列表GetMenuRights（）；此选择的结果集未映射到您的实体。您应该使用jdbc模板和映射manually@Alexander.Furer我需要在hibernate中显示上面查询中的值，如何使用三个实体？@Alexander.furr我遵循了下面的步骤
