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");
}
}
