如何寫一個HQL來獲取所有記錄，沒有權限

-1

Project 
    id, name 
ProjectAuthorization 
    id, project_id, user_id , permission 
User 
    id, name

Project.java

@OneToMany(mappedBy = "project", cascade = CascadeType.ALL) 
private List<ProjectAuthorization> permissions;

User.java

@OneToMany(mappedBy = "user",cascade =CascadeType.ALL) 
private List<ProjectAuthorization> permissions;

ProjectAuthorization.java

@ManyToOne() 
private Project project; 
@ManyToOne() 
private User user;

我想獲得所有的項目，沒有任何權限的當前用戶，如何通過休眠查詢寫它？

更新

HQL是這樣的：

select p from Project as p left join p.permissions as pa where pa.user.id!=:userid and p.id not in (select pa2.project.id from ProjectAuthorization as pa2 where pa2.user.id=:userid)");

你這些表之間有任何關聯映射？ –

是的，項目有OneToMany權限，用戶也有OneToMany權限 – atu0830

讓我們看看他們的映射 –

例如下面的查詢（也有效JPQL，在使用中沒有Hibernate的具體結構）可用於：

SELECT p 
FROM Project p 
WHERE p.id NOT IN 
    (SELECT authorization.project.id 
    FROM ProjectAuthorization authorization 
    WHERE authorization.user = :currentUser)
