这个问题在这里已经有了答案:





javax.faces.application.ViewExpiredException: View could not be restored

(10 个回答)


6年前关闭。




无论我做什么，我都会得到 javax.faces.application.ViewExpiredException: viewId。我知道如何处理异常(如果出现错误，再次重定向到主页)，问题是我从 commandButton 调用的任何操作都没有执行。

基本上我有一个带有 Action 的 commandButton 的简单 View 。我按下它，我得到 viewExpiredException 或者如果我处理错误，我没有收到错误消息，但我的 commandButton 仍然不起作用。

我尝试添加这个:

 <context-param>
     <param-name>javax.faces.PARTIAL_STATE_SAVING</param-name>
     <param-value>client</param-value>
 </context-param>

但它不起作用。我不知道发生了什么..

这是我的观点:

支持 bean : 
@ManagedBean(name="insert")
@ViewScoped
public class comparaDatosBean implements Serializable {

    private static final long serialVersionUID = 1L;
    Map<String, Object> parametros=new HashMap<String, Object>();
    Map<String, Object> params2=new HashMap<String, Object>();

    @PostConstruct
    public void init(){
        System.out.println("pase por aqui!!");
    }

    public void insertPublicacionDB() throws SQLException {
        ApplicationContext applicationContext = FacesContextUtils.getWebApplicationContext(FacesContext.getCurrentInstance());
        ControllerPublicacion controlador= (ControllerPublicacion) applicationContext.getBean("controllerPublicaciones");
        parametros.put("ut","234567876545555");
        parametros.put("py", 2013);

        params2.put("ut", "234567876545555");
        params2.put("bp","asjñldfkjsñd");
        params2.put("la", "Español");
        params2.put("ti","Publicacion de prueba");
        params2.put("py",2013);
        params2.put("sn", "234wf");
        params2.put("di", "asdfsf");
        params2.put("j9", "");
        params2.put("dt", "");
        params2.put("ga", "");
        params2.put("dt", "");
        params2.put("so", "");
        params2.put("fx", "");
        params2.put("ep", "");
        params2.put("issue", "");
        params2.put("parte","");
        params2.put("vl", "");
        params2.put("rp", "");
        params2.put("vinculada", null);
        params2.put("ji", "");
        params2.put("pd","");
        params2.put("pg", "");
        params2.put("pa","");
        params2.put("ab","");
        params2.put("pi", "");
        params2.put("numero_articulo", null);
        params2.put("tipo_carga_revista",null);
        params2.put("id",null );
        params2.put("su", "");
        System.out.println(params2.get("la"));
        if(controlador.existeEnDB(parametros)>0){
            System.out.println("La publicacion ya existe en la Base de Datos");
        } else {
            controlador.insertPublicacion(params2);
            System.out.println("la publicacion ha sido añadida");
        }

    }

    public Map<String, Object> getParametros() {
        return parametros;
    }

    public void setParametros(Map<String, Object> parametros) {
        this.parametros = parametros;
    }

    public Map<String, Object> getParams2() {
        return params2;
    }

    public void setParams2(Map<String, Object> params2) {
        this.params2 = params2;
    }

}

我需要的是知道为什么会发生这种情况，而不是如何处理异常.. 我无法从 commandButton 调用任何操作，因为没有任何 react 。

最佳答案

我用这个解决了它:

 <context-param>
     <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
     <param-value>client</param-value>
 </context-param>

在某些地方我是这样看到的 javax.faces.PARTIAL_STATE_SAVING但它没有用。
