有没有办法为tomcat的web.xml中的所有错误代码配置一个自定义错误页面的使用?

问题描述

正如标题中所说，我想更改tomcat中的默认错误页面并做到了:

As said in the in the title, I want to change default error pages in tomcat and did:

<error-page>
  <error-code>500</error-code>
  <location>/error_500.html</location>
</error-page>

 <error-page>
   <error-code>404</error-code>
   <location>/error_404.html</location>
</error-page>

是否可以使用通配符错误代码，例如

Is it possible to use wildcard error codes like

<error-page>
  <error-code>*</error-code>
  <location>/error.html</location>
</error-page>

?

(上面的例子不起作用，但还有其他方法吗?)

(The example above doesn't work, but is there another way?)

谢谢

推荐答案

不，Tomcat 没有办法.

No, there is no way in Tomcat.

Servlet 3.0 规范支持如下全局错误页面:

The Servlet 3.0 specification supports a global error page as follows:

<error-page>
    <location>/error.html</location>
</error-page>

所以理论上它至少应该在 Tomcat 7.0 中工作.但它没有在 Tomcat 7.0 中正确实现.我曾经报告过issue 52135，但他们否认了.不过，它适用于其他 Servlet 3.0 容器.

So in theory it should work in at least Tomcat 7.0. But it's not properly implemented in Tomcat 7.0. I have ever reported issue 52135 about this, but they denied it. It works on other Servlet 3.0 containers though.

然而，您可以通过实施特定于 Tomcat 的 ErrorReportValve 类，然后您将其注册为 <主机错误ReportValveClass>.

You can however workaround this by implementing a Tomcat-specific ErrorReportValve class which you then register as <Host errorReportValveClass>.
