Answer 1

你检查过日志文件了吗？您是否收到 Error executing action 之类的错误消息。

你得到 StringIndexOutOfBoundsException 可能是因为 NullPointerException 在下面的代码中将你的异常转换为 java-script-error

response.getWriter().write(KernelUtils.getInstance().createErrorJavaScript(e));

Answer 2

我得到的答案不是我的错，但我使用 tomcat 版本 8.0.32 并且有错误所以为了解决这个问题我有 将我的 tomcat 版本从 8.0.32 降级到 8.0.26 以解决我的问题。

以上错误是 tomcat 本身的错误。所以通过 link 来解决这个问题。

谢谢。
