将相同的Seam类绑定到不同的上下文变量

Question

我上州立大学的课。我需要会话作用域中的两个新状态对象注入到我的两个控制器中。每当创建mycontroller时，我都希望实例化对象的状态。当我使用下面的语法时，我在两个控制器中都注入了相同的状态对象。

我想要等同于

session.setAttribute("myFirstControllerState", myScreenStateObj1);
session.setAttribute("mySecondControllerState", myScreenStateObj2);


@SuppressWarnings("serial")
@AutoCreate
@Name("myScreenState")
@Scope(ScopeType.SESSION)

public class MyScreenState implements Serializable {

}

@AutoCreate
@Name("myFirstScreenController")
@Scope(ScopeType.PAGE)
@SuppressWarnings("serial")

public class MyFirstController implements Serializable {
   @In(value="myScreenState")
   @Out(value="myScreenState")
   private MyScreenState myFirstControllerState;
}

@AutoCreate
@Name("mySecondScreenController")
@Scope(ScopeType.PAGE)
@SuppressWarnings("serial")

public class MySecondController implements Serializable {

    @In(value="myScreenState")
    @Out( value="myScreenState")
    private MyScreenState mySecondControllerState;
}

Answer 1

我想通了。将@Roles注释添加到状态类。

@SuppressWarnings("serial")
@AutoCreate
@Name("myScreenState")
@Scope(ScopeType.SESSION)
@Roles({@Role(name="myState1", scope=ScopeType.PAGE),  
    @Role(name="myState2",scope=ScopeType.PAGE)})

public class MyScreenState implements Serializable {

}

在控制器中只需使用

private MyScreenState myState1;
