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"); } }
