SPRING-MVC RESTful Web Services

Spring can easily integrate a variety of restful styles of web-service, but in fact SPRING-MVC has provided this support.

You can generate XML, JSON, text, and other formats as needed.

Generating XML relies on JAXB, mainly @xmlrootelement, @XmlAttribute, @XmlElement and other annotations, JDK1.6 began with JAXB.

Generating JSON requires Jackson, who relies on Jackson-mapper-asl-xxx.jar, Jackson-core-asl-xxx.jar. MAVEN relies on the following, JACKSON-CORE-ASL will automatically join.

<!--Jackson--><dependency> <groupId>org.codehaus.jackson</groupId> <artifactId> Jackson-mapper-asl</artifactid> <version>1.7.9</version></dependency>

The following is a simple controller. produces in @RequestMapping annotations specifies the format of the output, XML, JSON, etc.

package com.spring.demo.web.controller;import javax.annotation.postconstruct;import  Org.slf4j.logger;import org.slf4j.loggerfactory;import org.springframework.http.httpstatus;import  org.springframework.http.MediaType;import org.springframework.stereotype.Controller;import  org.springframework.web.bind.annotation.requestmapping;import  org.springframework.web.bind.annotation.responsebody;import  org.springframework.web.bind.annotation.responsestatus;import com.spring.demo.core.entity.member;/**  * rest demo *  *  @author  sean *  */@ Controller@requestmapping ("/rest") public class restcontroller {         private logger logger = loggerfactory.getlogger (GetClass ());     private Member member;     @PostConstruct      Public void postconstrucT ()  {        member = new member ();         member.setemail ("[email protected]");         member.setname ("Zhang San");         member.setstreet (" South Mt.
