我的struts.xml里的配置：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>
<constant name="struts.devMode" value="true" ></constant>
<package name="struts2" extends="struts-default" namespace="/com/cw/struts">
<action name="register" class="loginAction" method="register">
<result name="success">/pages/my_management.jsp</result>
<result name="error">/pages/error.html</result>
</action>
</package>

web.xml 对application 加载的配置文件：
<!-- 将spring地址导入到web.xml中 -->
<!-- 用来定位Spring XML文件的上下文配置 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext-*.xml,classpath*:applicationContext-*.xml</param-value>
</context-param>
<!--Spring ApplicationContext 载入 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
</web-app>

Answer 1

这种问题我经常遇到，反正是自己出心造成的。我建议楼主，仔细比对。不过我觉得你的命名空间有问题。默认的是“/”。你把namespace="/com/cw/struts"去掉试试

Answer 2

package name="struts2" extends="struts-default" namespace="/com/cw/struts">
namespace值是指向包名下的文件,所以在namespace里不需要加上/com/cw包名

Answer 3

错误信息提示的很明白了，程序没有找到register关联的action。
从你的action的配置入手，看看你配置的命名空间和你访问的命名空间是否一致。

Answer 4

你应该把你触发Action的js函数,或提交方式拿出来,看看你那触发路径是怎么写的?
