配置服务器

1、web.xml过滤器

   <filter>
  <filter-name>struts2</filter-name>
  <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
  
  <filter-mapping>
  <filter-name>struts2</filter-name>
  <url-pattern>/*</url-pattern>
  </filter-mapping>

2、struts.xml

从E:struts-2.5.20appsstruts2-rest-showcaseWEB-INFclasses中复制到src文件夹下，删除不需要的内容

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE struts PUBLIC
