使用@MapKey注释

Question

在这些examples，Hibernate的存储映射，因为@MapKey和hibernate@MapKeyManyToMany已过时，我tryed弄清楚这种情况下，没有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; 
    } 

用户

@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; 
    } 

我也试过@MapKeyColumn,@MapKeyJoinColumn/@MapKeyColumn，而是使用相同的resault。 org.hibernate.AnnotationException：由导致异常

非法尝试以非集合映射为@OneToMany，@ManyToMany或@CollectionOfElements：com.path.taskAssignationState

我在另一个威胁阅读类似的问题，以及解决办法是使一个Set然后加入表格。但我想有一种使用这些注释的方法。

编辑

以前的问题是固定的，只需要返回一个列表。

但现在我面对这等万阿英，蒋达清：
