JSF.在每个页面加载时调用backing bean方法

import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import javax.faces.event.AbortProcessingException;
import javax.faces.event.ComponentSystemEvent;
import javax.faces.event.ComponentSystemEventListener;
import javax.faces.event.PreRenderViewEvent;

@ManagedBean
@RequestScoped
public class MyBackingBean implements ComponentSystemEventListener {

    public void processEvent(ComponentSystemEvent event) throws AbortProcessingException {
        if (event instanceof PreRenderViewEvent) {
            // 在这里调用backing bean中的方法
            myMethod();
        }
    }

    public void myMethod() {
        // 在这里实现方法的逻辑
    }

}
