LoginAction.java
创建package命名为com.itlwc.action
在package下面创建文件class文件：LoginAction.java
package com.itlwc.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;public class LoginAction extends Action { // ActionMapping对象里面装载的是struts-config.xml文件中的配置信息 // ActionForward类:封装了servlet中的跳转命令 @Override public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { String username = request.getParameter("username"); String password = request.getParameter("password"); if ("lwc".equals(username)&&"123".equals(password)) return mapping.findForward("success"); else return mapping.findForward("unsuccess"); }}
