网上我找了一天了，有的是struts-config.xml中的路径错了
有的是applicationContext.xml中的action路径错了
但是我对了半天，甚至这些路径都用复制的还是不行

spring的application 中已经申明过
<bean name="/login" class="com.test.struts.action.LoginAction" singleton="false">

struts。config文件中还是
type="org.springframework.web.struts.DelegatingActionProxy"
好像这样是不对的

[kjfurjcudj]

org.springframework.web.struts.DelegatingActionProxy 找不到这个类
你用eclipse搜一下 看能不能搜到

[kingwang1001]

和我们的项目比较了一下，应该没什么问题，就是web.xml中元素的位置有些不同，你把<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
放到<display-name>
LoginTest</display-name>之后试试
