打开JSF页面会给出以下异常：

  

引起：java.lang.IllegalStateException：在提交响应后无法创建会话

这是JSF代码：

这个问题是如何引起的？如何解决？我正在使用Mojarra 2.1.2。

4 个答案:

答案 0 :(得分：17)

原因是：

  1. JSF将页面组件结构存储在HttpSession
    2. 中
  2. 如果页面内容非常大且之前未创建会话，则可能已写入某些响应并且上述错误发生

    3. 因此，解决方案是在打印Facelet（/ JSP）页面之前创建会话。一个粗略的例子可能是：

    @PostConstruct
void initialiseSession() {
    FacesContext.getCurrentInstance().getExternalContext().getSession(true);
}

答案 1 :(得分：15)

[解决]

诊断这个问题花了好几天，但最后我能够解决这个问题。

它实际上是@ViewScoped并且它有一个托管属性DAO对象，它没有被序列化。因此，在渲染视图之后，facelets也会产生此异常，但JSF视图已经呈现，这就是此异常显示的原因。

解决方案：在@ViewScoped bean中对所有对象进行序列化，并标记未处理序列化的“瞬态”，就像我的情况一样，它是JSF @ViewScoped中的DAO对象。 / p>

答案 2 :(得分：9)

我把它放在我的web.xml中以解决我的一个应用程序的问题。

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

但奇怪的是，我在这个相同的玻璃鱼实例上托管了其他几个应用程序，这些应用程序在web.xml中不需要这个voodoo。

我非常想相信这不是解决方案，因为它对我来说没有任何意义，为什么这个特定的应用程序需要它而其他人没有。但是现在它有效。

答案 3 :(得分：2)

这也发生在我身上。

我曾经有过Mojarra 2.1.13，在将其更新到2.1.29后，问题解决了，我的代码没有任何变化。
