Rest is an architectural style that uses URLs to access any resource on the network. One of the thoughts of rest is to use the action Get,post,put,delete in HTTP to do the additional pruning and checking.
This is the rest request for SPRINGMVC. Examples of jax-rs that do not contain webservice. The rest-style webservice can be implemented with the CXF framework. Also very simple.
1 First prepare the jar package required for the Web project, which is the jar that SPRINGMVC depends on:
2 Create a Dynamic Web project: Here first the CONFIG. xml file is registered SPRINGMVC's front controller, Dispatcherservlet, and all client requests are forwarded by him. Then configure Hiddenhttpmethodfilter to turn the POST request into put and delete
<?XML version= "1.0" encoding= "UTF-8"?><Web-appXmlns: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= "webapp_id"version= "3.0"><!--Hiddenhttpmethodfilter can turn the POST request into a put delete--<Filter> <Filter-name>Hiddenhttpmethodfilter</Filter-name> <Filter-class>Org.springframework.web.filter.HiddenHttpMethodFilter</Filter-class> </Filter> <filter-mapping> <Filter-name>Hiddenhttpmethodfilter</Filter-name> <Url-pattern>/*</Url-pattern> </filter-mapping> <!--Configure the SPRINGMVC dispatcherservlet distribution request, in fact he is a front-end controller - <servlet> <Servlet-name>Dispatcherservlet</Servlet-name> <Servlet-class>Org.springframework.web.servlet.DispatcherServlet</Servlet-class> </servlet> <servlet-mapping> <Servlet-name>Dispatcherservlet</Servlet-name> <Url-pattern>/</Url-pattern> </servlet-mapping></Web-app>
3 Writing the rest-style interface
PackageCn.bean.demo.service;ImportOrg.springframework.stereotype.Controller;Importorg.springframework.web.bind.annotation.PathVariable;Importorg.springframework.web.bind.annotation.RequestMapping;ImportOrg.springframework.web.bind.annotation.RequestMethod; @Controller @requestmapping (Value= "/restservice") Public classRestservice { Public Final StaticString succeedd= "Show"; /*** GET request * URL:http://localhost: 8080/SPRINGMVC/RESTSERVICE/TESTRESTGET/12 *@paramID * Parameters for query *@return */@RequestMapping (Value= "/testrestget/{id}", method=requestmethod.get) PublicString Testrestget (@PathVariable ("id") (Integer ID) {SYSTEM.OUT.PRINTLN ("Rest-style GET request ... id=." +ID); returnSucceedd; } /*** Post new * URL:http://localhost: 8080/springmvc/restservice/testrestpost *@return */@RequestMapping (Value= "/testrestpost", method=requestmethod.post) PublicString Testrestpost () {System.out.println ("Rest-style POST request .... "); returnSucceedd; } /*** PUT Modify action * URL:http://localhost: 8080/springmvc/restservice/testrestput/put123 *@paramname *@return */@RequestMapping (Value= "/testrestput/{name}", method=requestmethod.put) PublicString Testrestput (@PathVariable ("name") (String name) {System.out.println ("Rest-style put request ..." name= "+name); returnSucceedd; } /*** Delete delete operation * URL:http://localhost: 8080/SPRINGMVC/RESTSERVICE/TESTRESTDELETE/11 *@paramID *@return */@RequestMapping (Value= "/testrestdelete/{id}", method=requestmethod.delete) PublicString testrestdelete (@PathVariable Integer id) {SYSTEM.OUT.PRINTLN ("Rest-style Delete request ... id=." +ID); returnSucceedd; } }
4 writing the interface's response page-The return of the interface
<%@ Page Language="Java"ContentType="text/html; Charset=utf-8"pageencoding="UTF-8"%><!DOCTYPE HTML PUBLIC "-//w3c//dtd HTML 4.01 transitional//en" "Http://www.w3.org/TR/html4/loose.dtd "><HTML><Head><Metahttp-equiv= "Content-type"content= "text/html; charset=utf-8"><title>Insert Title here</title></Head><Body> <H2>Show this is Succeedd? Yes</H2></Body></HTML>
5 Publishing and configuring the Rest interface Dispatcherservlet-servlet.xml:
<?XML version= "1.0" encoding= "UTF-8"?><Beansxmlns= "Http://www.springframework.org/schema/beans"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"Xmlns:context= "Http://www.springframework.org/schema/context"Xmlns:mvc= "Http://www.springframework.org/schema/mvc"xsi:schemalocation= "Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd Http://www.springframework.org/schema/context http://www.springframework.org/schema/context/ Spring-context-4.0.xsd Http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/ Spring-mvc-4.0.xsd "> <!--Configuring a custom scanned package - <Context:component-scanBase-package= "Cn.bean.demo"></Context:component-scan> <!--Configure the View resolver: How to resolve the handler method return value to the actual physical view - <Beanclass= "Org.springframework.web.servlet.view.InternalResourceViewResolver"> < Propertyname= "prefix"value= "/web-inf/views/"></ Property> < Propertyname= "suffix"value= ". jsp"></ Property> </Bean></Beans>
