救命啊，疯了！struts.xml都删了，还能找到action！！！

Question

别人的项目struts2+spring3.1+hibernate3，开始是说loginAction找不到名为success的result，但是在struts.xml中有login的action配置，也有result，于是把这个action配置删了，竟然还能调用到原来的LoginAction类，最后把struts.xml都删了，还能调到这个LoginAction类！！！
已经把Eclipse重启、Tomcat下webapps和work里的项目清空、重新发布、重新启动Tomcat、清空IE缓存做了N次了，还不行，为啥？有什么默认的login配置么？

Answer 1

web项目从web.xml开始看起，看看都有哪些配置，然后根据配置路径一个个去找
web.xml是万物之源！！！

Answer 3

 <!-- 如果不指定contextConfigLocation， 则默认从/EWB-INF/下查找applicationContext.xml文件 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath*:applicationContext*.xml
        </param-value>
    </context-param>
很明显，下一个查找对象是这个..

Answer 4

那是不可能的，只不过把xml变成注解而已，那样更零散，更加难以管理和理解，在大型项目中一般都不会推荐使用注解来替代配置的

Answer 5

只有一个applicationContext.xml

Answer 6

这就很诡异了，我在想 你操作的项目是不是 和你tomcat 发布的项目 是同步的。

Answer 7

 <!-- 使用Spring的Annotation -->
    <context:annotation-config />
    <context:component-scan base-package="com.lntu.admin">
    </context:component-scan>
 注解啊，这个有点汗啊，包就是这个com.lntu.admin，去相应包下看看吧，估计就在那个类的头上标着呢.....

Answer 8

会不会tomcat中有些文件没更新啊。

Answer 9

类中有木有注解  或者干脆  LoginAction   CTRL+H  *.XML
