struts 2.x的配置文档。

注意：这个应该放在web-inf下的classes文件夹里面。文件名为struts.xml

classes目录在Eclipse下是看不到的。需要手动拷贝过去。

而1.x版本是直接在web-inf目录下。

<?xml version="1.0" encoding="UTF-8" ?>
  <!DOCTYPE struts PUBLIC
      "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
      "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
    <include file="struts-default.xml"></include>
    <package name="struts_login" namespace="/login" extends="struts-default">
        <action name="login" class="com.myeclipseide.examples.struts.action.UserLoginAction" >
            <result name="success">/userLoginSuccess.jsp</result>
            <result name="WrongName">/userLogin.jsp</result>

<!--这个name属性就是前面的action（java）execute方法的返回值，通过不同的返回值调入不用的结果页面-->
            <result name="WrongPass">/userLogin.jsp</result>
        </action>
    </package>
    
</struts>

 

注意：package.name是唯一的名字。

　　　package.namespace是和url属性有关的，这个需要和前面的<s:form>标签的namespace相同

　　　action的name要和<s:form>的action值相同。

 

最后将这个项目下的webroot文件夹都拷贝到tomcat的webroot下。启动tomcat

输入http://localhost:8080/【webroot】/userLogin.jsp

这里这个webroot就是你拷贝进去的文件夹名，可以修改成别的名。这个文件夹和tomcat的webroot不要弄混了
