Question

我正在尝试在我的web.xml文件中添加此过滤器并在Liberty服务器上运行它。此配置在Tomcat上运行。但是在Liberty上我收到错误Exception thrown by application class 'java.lang.String.substring:1339'

Liberty有一些长度限制吗？

<filter>
     <filter-name>jersey</filter-name>
     <filter-class>com.sun.jersey.spi.container.servlet.ServletContainer</filter-class>
     <init-param>
       <param-name>com.sun.jersey.config.property.WebPageContentRegex</param-name>
       <param-value>/(flex|images|js|css|jsp)/.*</param-value>
     </init-param>
          <init-param>
       <param-name>com.sun.jersey.config.property.packages</param-name>
       <param-value>com.sun.jersey;com.netflix</param-value>
     </init-param>
  </filter>

堆栈追踪：

不清楚错误与web.xml中的值有关。从ContainerRequest.getPath API的读取，其中“获取当前请求相对于基本URI的路径作为字符串”，要查看的是请求URI以及在com.sun类中完成的处理，堆栈中列出的几个。由于API正在计算相对路径，因此有几种可能性表明：com.ibm Web容器请求处理代码提供的路径值不一致或不正确;提供给com.sun类的意外但有效的路径值;相对路径计算代码中的错误。我不确定你会如何得到这些，但起点是找出正在处理的两个URI：请求URI和基URI。

Websphere Liberty中的Web.xml错误，而不是Tomcat中的错误
