maven项目spring框架中整合restful

一、restful介绍

springmvc的resturl是通过@RequestMapping 及@PathVariable annotation提供的,
通过如@RequestMapping(value="/blog /{id}",method=RequestMethod.DELETE)即可处理/blog/1 的delete请求.

在发送请求传递参数时，不再是localhost:8080/blog?id=1这种形式，而是localhost:8080/blog/1.

@RequestMapping(value="/blog/{id}",method=RequestMethod.DELETE)
public ModelAndView delete(@PathVariable Long id,HttpServletRequest request,HttpServletResponse response)　{
blogManager.removeById(id);
return new ModelAndView(LIST_ACTION);
}

这样，在controller中就可以取到id=1的参数了。

二、配置restful

1、web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="schedule-console" version="3.0">

<!-- 配置spring的servlet -->
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!--　覆盖default　servlet的/,　springmvc　servlet将处理原来处理静态资源的映射　-->
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

<!--　该servlet为tomcat,jetty等容器提供,将静态资源映射从/改为/static/目录，如原来访问　http://localhost/foo.css　,现在http://localhost/static/foo.css　-->
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>/static/*</url-pattern>
</servlet-mapping>

<!--　URL重写filter,用于将访问静态资源http://localhost/foo.css　转为http://localhost/static/foo.css　-->
<filter>
<filter-name>UrlRewriteFilter</filter-name>
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
<init-param>
<param-name>confReloadCheckInterval</param-name>
<param-value>60</param-value>
</init-param>
<init-param>
<param-name>logLevel</param-name>
<param-value>DEBUG</param-value>
</init-param>
</filter>

<!--　浏览器不支持put,delete等method,由该filter将/blog?_method=delete转换为标准的http　delete方法　-->
<filter>
<filter-name>HiddenHttpMethodFilter</filter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>

<filter-mapping>
<filter-name>HiddenHttpMethodFilter</filter-name>
<servlet-name>springmvc</servlet-name>
</filter-mapping>

<!-- Spring的log4j监听器 -->
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

<!-- 字符集 过滤器  -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<!-- 欢迎页 -->
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<!-- 设置session有效时间 -->
<session-config>
<session-timeout>9999</session-timeout>
</session-config>

</web-app>

2、在pom.xml添加依赖，引入jar包

<!-- URL重写filter,用于将访问静态资源http://localhost/foo.css　转为http://localhost/static/foo.css -->
<dependency>
<groupId>org.tuckey</groupId>
<artifactId>urlrewritefilter</artifactId>
<version>4.0.4</version>
</dependency>

3、Controller编写

package com.zp.test.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/userinfo")
public class UserController {

@RequestMapping(value="/{id}")
public void test(@PathVariable Long id,HttpServletRequest request,HttpServletResponse response){

System.out.println(id);

}

}

4、jsp页面

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!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=ISO-8859-1">
<title>Insert title here</title>
</head>
<script type="text/javascript" src="static/js/jquery-1.10.1.min.js"></script>
<script>
function test1(){

$.ajax({
url:"/test2/userinfo/5",
data:{},
type:"post",
dataType:"json",
success:function(data){
alert("success");
},
error:function(){
alert("error");
}
});

}

function test2(){
window.location.href="test2.jsp";
}

</script>
<body>
<input type="button" value="test1" onclick="test1();"/>
<input type="button" value="test2" onclick="test2();"/>
</body>
</html>

5、启动服务，输入网址：localhost:8080/test2



test1按钮是发送请求，进入controller;

test2按钮是跳转静态页test2.jsp.

控制台输出：5，证明restful搭建成功
