Tomcat 8.0 重写 Valve [英] Tomcat 8.0 Rewrite Valve

问题描述

我正在尝试在 Tomcat 8.0 中使用 RewriteValve http://tomcat.apache.org/tomcat-8.0-doc/rewrite.html

I am trying to use the RewriteValve in Tomcat 8.0 http://tomcat.apache.org/tomcat-8.0-doc/rewrite.html

在 $CATALINA_HOME/conf/server.xml 中，我添加了

In $CATALINA_HOME/conf/server.xml, I added

<Valve className="org.apache.catalina.valves.rewrite.RewriteValve" />

就在 Host 标签下方

right below the Host tag

<Host name="localhost"  appBase="webapps" unpackWARs="true" autoDeploy="true">

在 $CATALINA_HOME/conf 目录中创建了一个 rewrite.config，内容如下

Created a rewrite.config in the $CATALINA_HOME/conf directory with the following

RewriteRule ^/abc /myapp

其中 http:/host:port/myapp 是一个正在运行的网络应用程序.

where http:/host:port/myapp is a working webapp.

所以现在当我去 http://host:port/abc 我希望被重定向到 http://host:port/myapp 但我得到一个 404 请求的资源不可用代替.

So now when I go to http://host:port/abc I expect to be redirected to http://host:port/myapp but I get a 404 the requested resource is not available instead.

看起来它甚至没有读取我的 rewrite.config 文件.日志目录中的访问日志只报告了"GET/abc HTTP/1.1" 404 1000，没有进一步的细节.

It doesn't look like it is even reading my rewrite.config file. The access log in the logs directory just reports the "GET /abc HTTP/1.1" 404 1000 with no further details.

我错过了什么?谢谢

推荐答案

在 Tomcat 文档中 http://tomcat.apache.org/tomcat-8.0-doc/rewrite.html 已写

In Tomcat documentation http://tomcat.apache.org/tomcat-8.0-doc/rewrite.html is written

重写阀可以配置为添加到主机中的阀.有关如何配置它的信息，请参阅虚拟服务器文档.它将使用包含重写指令的 rewrite.config 文件，它必须放在主机配置文件夹中.

The rewrite valve can be configured as a valve added in a Host. See virtual-server documentation for informations how to configure it. It will use a rewrite.config file containing the rewrite directives, it must be placed in the Host configuration folder.

所以尝试将 rewrite.config 移动到 $CATALINA_HOME/conf/Catalina/localhost

小提示:你可以在 rewrite.config 中拼错一些东西(例如 xxRewriteRule )，然后如果 tomcat 读取这个文件它会失败.我认为在你的情况下，即使你拼错了一些东西，tomcat 也会启动(因为它没有被读取).

so try to move rewrite.config into $CATALINA_HOME/conf/Catalina/localhost

Small hint: you can misspell something in rewrite.config ( e.g. xxRewriteRule ) and then if tomcat reads this file it fails. I think in your case tomcat starts even if you misspell something (because it is not read).
