1、导入jar包
可以参考struts官方包里的实例,apps目录下有几个war包,解压缩,里面就是一个完整的struts实例,将lib目录下的jar文件复制过来就可以了
2、web.xml
需要在web.xml中添加:
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>Struts Blank</display-name> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>index.html</welcome-file> </welcome-file-list> </web-app>
3、struts.xml(配置action)
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd"> <struts> <constant name="struts.enable.DynamicMethodInvocation" value="false" /> <constant name="struts.devMode" value="true" /> <package name="ru" namespace="/" extends="struts-default"> <default-action-ref name="index" /> <global-results> <result name="error">/error.jsp</result> </global-results> <action name="login" class="com.ru.domain.loginaction"> <result name="sucess"> /jsp/logsucess.jsp </result> <result name="error"> /jsp/logerror.jsp </result> </action> </package> </struts>
4、LoginAction.java(action类)
package com.ru.action; import com.opensymphony.xwork2.ActionSupport; import com.ru.service.UserCheck; public class LoginAction extends ActionSupport { private String username; private String password; public void setUsername(String username) { this.username = username; } public void setPassword(String password) { this.password = password; } @Override public String execute() throws Exception { //UserCheck是一个service类 UserCheck uc=new UserCheck(); if(uc.result(username, password)=="sucess"){ return "sucess"; }else{ return "error"; } } }
5、login.jsp
注意的是:action实现的是重定向,说以需要完整访问路径,这里使用<base href="<%=basePath%>">,获取完整路径
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@taglib uri="/struts-tags" prefix="s"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <base href="<%=basePath%>"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <!-- 使用struts标签创建一个表单 --> <s:form action="login" method="post"> <s:textfield key="用户名" name="username"></s:textfield> <s:password key="密 码" name="password"></s:password> <s:submit value="登录"></s:submit> </s:form> </body> </html>
