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
