初学Struts遇到的坑爹问题

主要页面

Action: LoginAction.java //用于处理登陆这个事件

FromBean: LoginForm.java //存储Login.jsp中传过来的表单内容

JSP:Login.jsp //登陆页面，提交到login.do

XML配置文件：struts-config.xml，web.xml

struts-config.xml配置文件：

 1 <struts-config>
 2     <form-beans>
 3         <form-bean name="loginForm" type="cn.strut.form.LoginForm" />
 4     </form-beans>
 5     <action-mappings>
 6         <action path="/login" type="cn.strut.action.LoginAction" name="loginForm">
 7 
 8             <forward name="LoginSuccess" path="/LoginSuccess.jsp"></forward>
 9             <forward name="LoginFailure" path="/LoginFailure.jsp"></forward>
10         </action>
11     </action-mappings>
12 </struts-config>

LoginAction.java

package cn.strut.action;import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;import cn.strut.form.LoginForm;public class LoginAction extends Action {@Overridepublic ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response)throws Exception {// TODO Auto-generated method stubLoginForm Lf=(LoginForm)form;System.out.println(Lf.getUserName());       //每次都输出nullif("AgoniShao".equals(Lf.getUserName())){return mapping.findForward("LoginSuccess");}else{return mapping.findForward("LoginFailure");}}}

LoginForm.java

package cn.strut.form;import org.apache.struts.action.ActionForm;public class LoginForm extends ActionForm {private String UserName;private String PassWord;public String getUserName() {return UserName;}public void setUserName(String userName) {UserName = userName;}public String getPassWord() {return PassWord;}public void setPassWord(String passWord) {PassWord = passWord;}}

<body><form action="<%=request.getContextPath() %>/login.do" method="post">UserName:<input type="text" name="UserName" /><br>PassWord:<input type="text" name="PassWord" /><br><input type="submit" value="OK"/></form></body>

web.xml

 1 <servlet>
 2      <servlet-name>action</servlet-name>
