struts2实例

开发工具：

eclipse Neon (4.6.0)

struts2.5.2

struts2.5.2是struts当前最新版本，该版本与此前2.3版本的不同之处(包含但不仅限于)：

1.struts2.5核心包已经将xwork的核心包含其中，因此在struts2版本包中的lib目录下已找不到xwork-core-xx.xx.xx.jar文件。

1.使用eclipse创建动态Web项目。

将struts2.5版本包中\apps\struts2-showcase.war包解压，将lib目录下的以下jar包复制到eclipse项目中的WebContent/WEB-INF/lib目录下：

asm-3.3.jar
asm-commons-3.3.jar
asm-tree-3.3.jar
commons-fileupload-1.3.2.jar
commons-io-2.4.jar
commons-lang3-3.4.jar
commons-logging-1.1.3.jar
freemarker-2.3.23.jar
javassist-3.20.0-GA.jar
log4j-api-2.5.jar
ognl-3.1.10.jar
struts2-core-2.5.2.jar

2.在WEB-INF目录下创建web.xml文件(若创建项目时自动创建则不再需要重新创建)，修改web.xml配置内容如下(参照struts2-showcase.war)的配置：

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <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">
 3   <display-name>mystruts2</display-name>
 4   <welcome-file-list>
 5     <welcome-file>index.html</welcome-file>
 6     <welcome-file>index.htm</welcome-file>
 7     <welcome-file>index.jsp</welcome-file>
 8     <welcome-file>default.html</welcome-file>
 9     <welcome-file>default.htm</welcome-file>
10     <welcome-file>default.jsp</welcome-file>
11   </welcome-file-list>
12     <filter>
13         <filter-name>struts-prepare</filter-name>
14         <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareFilter</filter-class>
15     </filter>
16 
17     <filter>
18         <filter-name>struts-execute</filter-name>
19         <filter-class>org.apache.struts2.dispatcher.filter.StrutsExecuteFilter</filter-class>
20     </filter>
21     <filter-mapping>
22         <filter-name>struts-prepare</filter-name>
23         <url-pattern>/*</url-pattern>
24     </filter-mapping>
25 
26     <filter-mapping>
27         <filter-name>struts-execute</filter-name>
28         <url-pattern>/*</url-pattern>
29     </filter-mapping>
30 </web-app>

web.xml

3.在src目录下创建struts.xml，文件内容可参照struts版本包自带的struts2-showcase.war实例中的web.xml。

 1 <?xml version="1.0" encoding="UTF-8" ?>
 2 
 3 <!DOCTYPE struts PUBLIC
 4     "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
 5     "http://struts.apache.org/dtds/struts-2.5.dtd">
 6 
 7 <!-- START SNIPPET: xworkSample -->
 8 <struts>
 9 
10     <package name="wei" extends="struts-default">
11 
12         <action name="login" class="com.info.action.LoginAction" method="execute">
13             <result name="success">/WEB-INF/welcome.jsp</result>
14             <result name="error">/WEB-INF/error.jsp</result>
15         </action>
16         
17     </package>
18 
19 
20 </struts>
21 
22 <!-- END SNIPPET: xworkSample -->

struts.xml

4.创建jsp页面。

 1 <%@ page language="java" contentType="text/html; charset=utf-8"
 2     pageEncoding="utf-8"%>
 3 <%@ taglib prefix="s" uri="/struts-tags" %>
 4 
 5 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 6 <html>
 7 <head>
 8 <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
 9 <title>Insert title here</title>
10 </head>
11 <body>
12 <s:form action="login" method="post">
13     <s:textfield name="username" label="用户名"></s:textfield>
14     <s:password name="password" label="密码"></s:password>
15     
16     <s:submit value="提交"></s:submit>
17 </s:form>
18 </body>
19 </html>

index.jsp

 1 <%@ page language="java" contentType="text/html; charset=utf-8"
 2     pageEncoding="utf-8"%>
 3 <!-- <%@taglib prefix="s" uri="/struts-tags" %>  -->
 4 <%@ taglib prefix="s" uri="/struts-tags" %>
 5 
 6 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 7 <html>
 8 <head>
 9 <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
10 <title>welcome</title>
11 </head>
12 <body>
13 welcome!
14 </body>
15 </html>

welcome.jsp

 1 <%@ page language="java" contentType="text/html; charset=utf-8"
 2     pageEncoding="utf-8"%>
 3 <!-- <%@taglib prefix="s" uri="/struts-tags" %>  -->
 4 <%@ taglib prefix="s" uri="/struts-tags" %>
 5 
 6 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
 7 <html>
 8 <head>
 9 <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
10 <title>error</title>
11 </head>
12 <body>
13 error!
14 </body>
15 </html>

error.jsp

5.src目录下创建action类。

 1 package com.info.action;
 2 
 3 public class LoginAction {
 4     
 5     private String username;
 6     private String password;
 7     
 8     public String getUsername() {
 9         return username;
10     }
11 
12     public void setUsername(String username) {
13         this.username = username;
14     }
15 
16     public String getPassword() {
17         return password;
18     }
19 
20     public void setPassword(String password) {
21         this.password = password;
22     }
23 
24     public String execute() throws Exception {
25         
26         if(this.getUsername().equals("admin")&&this.getPassword().equals("admin"))
27         {
28             return "success";
29         }
30         
31         return "error";
32         
33     }
34 
35 }

LoginAction.java
