(上篇：Struts2 - Rest(1))
6) 加入user-index.jsp到/WEB-INF/content中：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags" %> <!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>User list</title> </head> <body> <a href="${pageContext.request.contextPath}/user/new">Add new user</a> <hr/> <s:actionmessage/><br/> <table> <thead> <th>ID</th> <th>User name</th> <th>Age</th> <th>View</th> <th>Edit</th> <th>Remove</th> </thead> <tbody> <s:iterator value="model"> <tr> <td><s:property value="id"/></td> <td><s:property value="username"/></td> <td><s:property value="age"/></td> <td><s:a href="user/%{id}">View</s:a></td> <td><s:a href="user/%{id}/edit">Edit</s:a></td> <td><s:a href="user/%{id}/destroy">Remove</s:a></td> </tr> </s:iterator> </tbody> </table> </body> </html>
7) 加入user-show.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> </head> <body> <a href="${pageContext.request.contextPath}/user">Back to home</a><hr/> User ID:<s:property value="id"/><br/> User Name:<s:property value="username"/><br/> User Age:<s:property value="age"/><br/> </body> </html>
8) 加入user-editNew.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags" %> <!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>Add new user</title> </head> <body> <a href="${pageContext.request.contextPath}/user">Back to home</a><hr/> <s:form method="POST" action="%{contextPath}/user"> User Name:<s:textfield name="username"></s:textfield><br/> User Age:<s:textfield name="age"></s:textfield><br/> <s:submit value="Submit"></s:submit> <s:reset value="Reset"></s:reset> </s:form> </body> </html>
9) 加入user-edit.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags" %> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>User edit</title> </head> <body> <a href="${pageContext.request.contextPath}/user">Back to home</a><hr/> <s:form method="POST" action="%{contextPath}/user/%{id}"> <s:hidden name="_method" value="put"></s:hidden> User ID:<s:textfield name="id" disabled="true"></s:textfield><br/> User Name:<s:textfield name="username" disabled="false"></s:textfield><br/> User Age:<s:textfield name="age" disabled="false"></s:textfield><br/> <s:submit value="Submit"></s:submit> <s:reset value="Reset"></s:reset> </s:form> </body> </html>
注意这里有一个hidden input，这个有个name="_method" value="put"的属性，意思是在这个form的提交是以PUT形式提交。这个不能少。不然rest认不出这是PUT提交。

结束总结：
1) 这个例子使用了ModelDriven action来做Controller的model，具体可以参考下这个小文：
http://www.cnblogs.com/shihujiang/archive/2012/06/30/2571050.html
2) 事实上，rest插件可以生成的转向是一个jsp，在url的action中加入.xml或.json，将会出现对应的xml或json，比如：
http://localhost:8080/TestWeb/user.xml
http://localhost:8080/TestWeb/user.json
更多的内容可参考官方文档说明：
