使用@MapKey註釋

Question

在這些examples，Hibernate的存儲映射，因爲@MapKey和hibernate@MapKeyManyToMany已過時，我tryed弄清楚這種情況下，沒有sucess：

taskAssignationState

protected Map<User, Boolean> usersState; 
@ManyToMany(
      cascade={CascadeType.ALL}, 
      mappedBy = "taskAssignationState", 
      fetch=FetchType.LAZY 
    ) 
    @MapKey(name = "user") 
    public Map<User, Boolean> getUsersState() { 
     return usersState; 
    } 
    public void setUsersState(Map<User, Boolean> usersState) { 
     this.usersState = usersState; 
    } 

用戶

@ManyToMany(cascade=CascadeType.ALL) 
    @JoinTable(name = "user_state_task_assignation", 
      joinColumns=@JoinColumn(name="username"), 
      inverseJoinColumns=@JoinColumn(name="assignation_state")) 
    public TaskAssignationState getTaskAssignationState() { 
     return taskAssignationState; 
    } 

    public void setTaskAssignationState(TaskAssignationState taskAssignationState) { 
     this.taskAssignationState = taskAssignationState; 
    } 

我也試過@MapKeyColumn,@MapKeyJoinColumn/@MapKeyColumn，而是使用相同的resault。 org.hibernate.AnnotationException：由導致異常

非法嘗試以非集合映射爲@OneToMany，@ManyToMany或@CollectionOfElements：com.path.taskAssignationState

我在另一個威脅閱讀類似的問題，以及解決辦法是使一個Set然後加入表格。但我想有一種使用這些註釋的方法。

編輯

以前的問題是固定的，只需要返回一個列表。

但現在我面對這等萬阿英，蔣達清：
