Eclipse 搭建Struts2

Eclipse版本 Mars Release (4.5.0)

Struts版本 struts-2.5.20 下载地址：https://struts.apache.org/download.cgi#struts2520

一、创建web项目

命名为MyStruts2

勾选web.xml

二、拷贝struts的jar包

从struts-2.5.20-all\struts-2.5.20\lib拷贝jar文件，复制到WEB-INF\lib文件夹下

然后配置web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns="http://xmlns.jcp.org/xml/ns/javaee"

 xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"

 id="WebApp_ID" version="3.1">

  <display-name>MyStruts2</display-name>

  <filter>

  	<filter-name>struts2</filter-name>

  	<filter-class>org.apache.struts2.dispatcher.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>index.htm</welcome-file>

    <welcome-file>index.jsp</welcome-file>

    <welcome-file>default.html</welcome-file>

    <welcome-file>default.htm</welcome-file>

    <welcome-file>default.jsp</welcome-file>

  </welcome-file-list>

</web-app>

　　路径为：

然后创建struts.xml, 路径为src/struts.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE struts PUBLIC

	"-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"

	"http://struts.apache.org/dtds/struts-2.5.dtd">

<!-- START SNIPPET: xworkSample -->

<struts>

   <!-- 是否开启动态方法调用 -->

    <constant name="struts.enable.DynamicMethodInvocation" value="true" />

	<package name="default" namespace="/" extends="struts-default">

		 <action name="login" class="com.example.struts2.LoginAction" method="login">

			<result name="success">/success.jsp</result>

			<result name="error">/error.jsp</result>

		</action>

	</package>

</struts>

三、进行测试

1、创建index.jsp

<%@ page language="java" contentType="text/html;charset=UTF-8" pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">

<title>Insert title here</title>

</head>

<body>  

    <form action="login.action" method="post">  

        用户名：<input type="text" name="username">  

        密码：<input type="text" name="password">  

        <input type="submit" value="提交">  

    </form>  

</body>

</html>

2、创建error.jsp

<%@ page language="java" contentType="text/html;charset=UTF-8"  pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">

<title>Insert title here</title>

</head>

<body>  

    Error!  

</body>

</html>

3、创建success.jsp

<%@ page language="java" contentType="text/html;charset=UTF-8" pageEncoding="UTF-8" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">

<title>Insert title here</title>

</head>

<body>  

    Success!  

</body>

</html>

4、新建一个Servlet类，用来将输入的用户名和密码进行测试，使用户名如果正确跳转到success页面，否则到error页面(继承ActionSupport与否都可以)

package com.example.struts2;

import com.opensymphony.xwork2.ActionSupport;

import javax.servlet.http.HttpServletRequest;

import org.apache.struts2.ServletActionContext;

public class LoginAction extends ActionSupport {

	HttpServletRequest req = ServletActionContext.getRequest();

	String username = req.getParameter("username");

	String password = req.getParameter("password");

	public String getUsername() {

		return username;

	}

	public void setUsername(String username) {

		this.username = username;

	}

	public String getPassword() {

		return password;

	}

	public void setPassword(String password) {

		this.password = password;

	}

	public String login(){

		if("Larry".equals(username)

				&& "123456".equals(password)){

			return "result";

		}else{

			return "error";

		}

	}

}

5、测试接口

1） Success

2）Error
