继续求解this problem ,我已将 Mojarra 替换为 MyFaces 并升级 JDK,当我在服务器重新启动后继续处理表单时,出现以下错误:
发生错误:
/food.xhtmlNo saved view state could be found for the view identifier: /food.xhtml

你没有遇到过这样的错误报告吗?
最佳答案
回复可能有点晚了,但我也遇到了同样的问题,并且花了相当多的时间来解决它。所以,我认为这可能对其他人有帮助。
默认情况下,MyFaces
会序列化状态,即使状态保存在服务器上,而 Mojarra
则不会。因此,如果您有一些不可序列化的 bean,或者正在使用其他不可序列化的 bean,您将看到该错误(服务器无法序列化该对象)。
您可以禁用序列化,以便 MyFaces
将像 Mojarra
一样工作。

关于java - 服务器重启后出现JSF问题: No saved view state could be found,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/6531373/
