这个问题是如何引起的，我如何解决它？我使用的是Mojarra 2.1.2。

已解决

诊断这个问题花了几天的时间，但最终我能够解决这个问题。

它实际上是@ViewScoped，它有一个未序列化的托管属性DAO对象。因此，在呈现视图之后，facelets也会产生此异常，但JSF视图已经呈现，这就是显示此异常的原因。

解决方案：使所有对象在JSF中序列化，并将未序列化的对象标记为“瞬态”，就像我的例子中的@ViewScoped @ViewScoped中的DAO对象一样。

原因是：

  1. JSF将页面组件结构存储在HttpSession
  2. If中页面内容非常大，以前没有创建过会话，可能已经写入了一些响应，出现了上面的错误

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这样：

代码语言：javascript
复制
@PostConstruct
void initialiseSession() {
    FacesContext.getCurrentInstance().getExternalContext().getSession(true);
}

我把这个放到我的web.xml中，以解决我的一个应用程序的问题。

代码语言：javascript
复制
<context-param>
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
    <param-value>client</param-value>
</context-param>

但奇怪的是，我在这个玻璃鱼实例上托管了其他几个应用程序，它们在web.xml中不需要这个巫毒。

我强烈地认为这不是解决方案，因为我不明白为什么这个特别的应用需要它，而其他应用不需要它，但现在它可以工作。
