Java 使用@MapKey注释休眠存储地图

接下来，由于中的

@MapKey

和

@mapkeymanytomy

已被弃用，我试图找出这种情况，但没有成功：

任务分配状态

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;
    }

我还尝试了

@MapKeyColumn

，

@MapKeyJoinColumn

/

@MapKeyColumn

，但结果相同。例外

原因：

org.hibernate.AnnotationException

：非法尝试将非集合映射为

@OneToMany

、

@ManyToMany

或

@collectionfelments

：

com.path.taskAssignationState

我在另一个威胁中读到了一个类似的问题，解决方法是做一个

集合

，然后加入表格。但我想有一种方法可以使用这些注释

编辑

前面的问题已经解决，只需要返回一个列表

@ManyToMany 
    @JoinTable(name = "user_state_task_assignation", 
            joinColumns=@JoinColumn(name="assignation_state"),
            inverseJoinColumns=@JoinColumn(name="username"))    
    @MapKeyJoinColumn(name="state")
    public Map<User, Boolean> getUsersState() {
        return usersState;
    }
    public void setUsersState(Map<User, Boolean> usersState) {
        this.usersState = usersState;
    }

    @ManyToMany(
            cascade={CascadeType.ALL},  
            mappedBy = "taskAssignationState",
            fetch=FetchType.LAZY
    )
    public List<TaskHistory> getTasksHistory() {
        return tasksHistory;
    }
    public void setTasksHistory(List<TaskHistory> tasksHistory) {
        this.tasksHistory = tasksHistory;
    }

@manytomy
@JoinTable（name=“用户\状态\任务\分配”，
joinColumns=@JoinColumn（name=“assignation\u state”），
inverseJoinColumns=@JoinColumn（name=“username”））
@MapKeyJoinColumn（name=“state”）
公共映射getUsersState（）{
返回usersState；
}
公共void setUsersState（映射usersState）{
this.usersState=usersState；
}
@许多(
cascade={CascadeType.ALL}，
mappedBy=“taskAssignationState”，
fetch=FetchType.LAZY
)
公共列表getTasksHistory（）{
返回任务历史；
}
public void settaskstory（列表taskstory）{
this.tasksHistory=tasksHistory；
}

但现在我面临另一个问题：

尝试从getTaskAssignationState方法返回TaskAssignationState列表

但是现在我得到了这个异常，原因是：org.hibernate.AnnotationException:使用@OneToMany或@ManyToMany针对未映射的类：com.path.TaskAssignationState.usersState[java.lang.Boolean]为什么我必须映射布尔类？？这是一个java类！！也许这意味着hashmap？无论如何，我尝试了我的hibernate.cfg.xml。没有成功让我们看到异常堆栈跟踪…我猜您使用的是org.hibernate导入而不是javax.persistenceNo，我使用的是javax.persistenceI checked，org.hibernate中不推荐使用@MapKey。所以我找艾尔
