java.lang.IllegalArgumentException：URLDecoder：不完整的尾随转义（）模式

Tin*_*iny 5 glassfish glassfish-4 jakarta-ee

我有一个类似的网址，

http://localhost:8080/Project-war/utility/Login.jsf?fallback=%2FProject-war%2Fpublic_resources%2FShowDetails.jsf%3Fid%3D9

当请求登录页面时，会形成此 URL。成功登录后请求将重定向到的返回 URL 作为查询字符串参数附加到 URL。

如果这个 URL 被用户故意更改，

http://localhost:8080/Project-war/utility/Login.jsf?fallback=%2FProject-war%2Fpublic_resources%2FShowDetails.jsf%3Fid%

一些尾随字符已被删除。这是一个格式错误的 URL。在这种情况下，它会导致抛出以下异常。

这个异常是内部发生的，不是我写的代码引起的。这种异常不应该发生。

如何解决/处理这个异常？

Bal*_*usC 4

这是 GlassFish4 中的一个错误。

没有办法从 webapp 端解决这个问题。不带Filter，不带ServletRequestListener，不带ServletContainerInitializer，甚至不带 GlassFish 特定的GlassFishValve。负责确定请求参数并从而触发此 GlassFish bug 的 Weld 是在 GlassFish 启动的很早的时候就在 GlassFish 自己的WebConfigListener. 由于 GlassFish 和 Weld 的紧密耦合，因此无法在触发ServletRequestListenerWeld之前运行某些代码。WeldListener如果可能的话，那么您可以request.getParameterMap()在委托之前在 try-catch 中调用。

您最好的选择是将此作为另一个问题报告给 GlassFish。然而，由于 Oracle 已停止对 GlassFish 的商业支持，因此您不应指望很快就会发布新的开源 GlassFish。如今，您最好使用WildFly（支持 Oracle/JBoss，并且已经准备好 Java EE 7）或TomEE（支持 Apache，但尚未准备好 Java EE 7）作为 GlassFish 开源版本的替代品。这些服务器足够聪明，可以跳过这种损坏的请求参数，只记录警告，而不是抛出IllegalArgumentException杀死整个 Web 应用程序的警告。
