我想通过注释@Query通过Jpa存储库进行Join查询。我有三个表。

本机查询是：

select application.APP_ID 
from user, customer, application 
where user.USE_CUSTOMER_ID = customer.CUS_ID 
and application.APP_CUSTOMER_ID = customer.CUS_ID 
and user.USE_ID=1;

现在我有了Table Hibernate实体，所以我在ApplicationRepository中尝试过

@Query(SELECT  application FROM  Application a
  INNER JOIN customer c ON c.customer.id = a.customer.id 
  INNER JOIN user u ON u.customer.id = c.customer.id
  INNER JOIN application a ON a.user.id = u.id
  WHERE
  u.id = :user.id)
List<Application> findApplicationsByUser(@Param("User") User user);

日志说

意外的标记

有什么想法吗？

我的表实体

Application.java：

@Entity
@Table
public class Application extends BaseSimpleEntity {
...
    @ManyToOne(optional = false)
    private Customer customer;
...
}

Customer.java：

@Entity
@Table
public class Customer extends BaseSimpleEntity {
...
    @OneToMany(mappedBy = "customer")
    private List<User> users;
    @OneToMany(mappedBy = "customer")
    private List<Application> applications;
...
}

User.java：

@Entity
@Table
public class User extends BaseSimpleEntity {
...
    @ManyToOne(optional = false)
    private Customer customer;
...
}
