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。
答案 0 :(得分:17)
原因是:
HttpSession
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);
}

[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。
