单击该页面上的按钮后，如何让JSF跳过getter方法调用？

Question

Actualy I want after clicking logout session get invalidate. But it is going firstly on getter setter and there I created a session. After that is goes to session invalidate method. And it will throw exception.

How would I skip getter setter on click of button and directly call the action method?

Answer 1

Just don't do business job in getters/setters. The getters/setters should solely do the things as their name suggests: returning a property or setting a property. Nothing more. It should not load/preinitialize properties. The loading/preinitializing should be done by a (post)constructor or action(listener) method.
