1.RESTful
a.定义:一种软件架构风格,设计风格而不是标准,只是提供了一组设计原则和约束条件。它主要用于客户端和服务器交互类的软件。基于这个风格设计的软件可以更简洁,更有层次,更易于实现缓存等机制。
b.四种方式:
GET:/blog/1 HTTP GET => 得到id=1的blog 一般用于读取
DELETE:/blog/1 HTTP DELETE => 删除id=1的blog 用于删除
PUT:/blog/1 HTTP PUT => 更新id=1的blog 用于更新
POST:/blog HTTP POST => 新增BLOG 用于增删改
2.使用步骤
a.将myRest中jar包考入
b.在web.xml中配置
<servlet-mapping> <servlet-name>myRest</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
c.在mySpring-servlet.xml中配置
<mvc:annotation-driven /> <mvc:resources mapping="/img/**" location="/img/" /> <mvc:resources mapping="/js/**" location="/js/" /> <mvc:resources mapping="/css/**" location="/css/" /> <mvc:resources mapping="/html/**" location="/html/" /> <mvc:default-servlet-handler />
以及
<bean id="myResourceHandler" name="myResourceHandler" class="org.springframework.web.servlet.resource.ResourceHttpRequestHandler"> <property name="locations" value="/" /> <property name="supportedMethods"> <list> <value>GET</value> <value>DELETE</value> <value>PUT</value> <value>POST</value> </list> </property> </bean>
d.建SqlMapConfig.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <typeAliases> <package name="com.wode.bean"/> </typeAliases> </configuration>
e.在html中
$("button").bind("click",function(){ $.ajax({ type: "put", url: "../user/update/13", data: {name:"zhangsan",location:"chengdu"}, success: function(msg){ alert( "Data Saved: " + msg ); } }); })
f.Controller中书写
@RequestMapping("/user") public class HelloController { // http://127.0.0.1:8080/myRestFul/user/update/3 @RequestMapping(path="/update/{id}",method=RequestMethod.PUT) public void upUser(@PathVariable("id")int id,String name,String location,PrintWriter pt){ //用户的修改 System.out.println("用户执行了更新"+id+" "+name+" "+location); pt.println("hello world"); } }
g.注意:put方式还需在web.xml中配置
<filter> <filter-name>httpPutFormFilter</filter-name> <filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class> </filter> <filter-mapping> <filter-name>httpPutFormFilter</filter-name> <servlet-name>myRest</servlet-name> </filter-mapping>
