Question

当我启动我的jsp时，我使用javascript函数在会话中向用户收费。 javascript函数使用带有struts2动作的JSON。这是代码：

JSP：

<body>
   <script>usarAJAXCargarCookie();</script>
   ...
</body>

使用Javascript：

function usarAJAXCargarCookie() {
   var userCookie = getCookie('userCookieSL');
   $.getJSON('ajaxCookie', {
      userCookie: userCookie
   }, function (jsonResponse) {
   });
}

struts.xml中

<action name="ajaxCookie" class="Acciones.HomeFavoritos" method="ajaxCookie">
   <result type="json">
      <param name="excludeNullProperties">true</param>
      <param name="noCache">true</param>
   </result>
</action>

HomeFavoritos.java

@SkipValidation
public String ajaxCookie() throws Exception{        
    if(sesion==null){
        sesion=ActionContext.getContext().getSession();
    }
    if(sesion.get("usuarioLogueado") == null || sesion.get("usuarioLogueado").equals("")){
        cargarUsuarioNoLogueado(sesion, userCookie);
    } else {
        cargarUsuarioLogueado(sesion);
    }
    return SUCCESS;
}

我收到此错误：

Answer 1

InvocationTargetException只是一个真正的例外，你没有向我们展示。

它可能是序列化异常，因此请考虑使用root object as described here，而不是序列化整个操作。

同时尝试在代码中使用英文名称，请不要使用不同于小写的内容编写包名称（ A cciones.HomeFavoritos ...）

使用Struts2
