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>&nbsp;<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>&nbsp;<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
