老是说There is no Action mapped for namespace / and action name query问题，但是我检查了很久觉得namespace没啥问题哇，

解决方案 »

  1.   

    namespace=""
    你为什么不填？
    你至少填个
    namespace="/"
      

  2.   

    这个应该是指在web路径，我填过/也是没用，网上查了下，很多都说在web-inf下好像不用写
      

  3.   

    web.xml
    <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.5.6" xmlns="http://java.sun.com/xml/ns/javaee"

  4.   

    应该是你的struts.xml没有起作用。看下你的action
      

  5.   

    我之前也遇到过这样的情况，
    http://bbs.csdn.net/topics/390356911
    这就是那个经历。。
    这样，你把配置规范的填一遍，运行，如果不行就右击工程Clean一下，删除class文件，然后重新编译运行，一般就可以了。
    如果还不行。
    退出Eclipse再进
      

  6.   

    你在web.xml中指定下struts.xml位置试一试吧
      

  7.   


    我有点怀疑是不是struts.xml没有起作用，但是我编译后看见classes 下的
    WEB-INF\classes\custom\struts.xml 有这个配置文件
    <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.5.6" xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee   
     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    <display-name>test</display-name>


    <!-- 加载Spring配置文件 -->
    <context-param>
    <param-name>contextConfigLocation</param-name>

    </context-param>
    <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!-- struts2 -->

    配置文件放到resources根目录，不要发放到custom里卖弄
