spring-REST

1.controller类：

package com.mzj.practice.controller;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

/**
 * Copyright (C),HANDPAY<br>
 *
 * SpringMVC REST
 *
 * @author muzhongjiang
 * @date 2014年10月26日
 */
@RequestMapping("/restful")
@Controller
public class RESTController {
    private final Logger LOG=Logger.getLogger(this.getClass());

    @RequestMapping(value = "/show", method = RequestMethod.GET)
    public ModelAndView show() {
        LOG.info("show");
        ModelAndView model = new ModelAndView("xStreamMarshallingView");
        model.addObject("show method");
        return model;
    }

    @RequestMapping(value = "/get/{id}", method = RequestMethod.GET)
    public ModelAndView getUserById(@PathVariable String id) {
        LOG.info("getUserById-" + id);
        ModelAndView model = new ModelAndView("xStreamMarshallingView");
        model.addObject("getUserById method -" + id);
        return model;
    }

    @RequestMapping(value = "/add", method = RequestMethod.POST)
    public ModelAndView addUser(String user) {
        LOG.info("addUser-" + user);
        ModelAndView model = new ModelAndView("xStreamMarshallingView");
        model.addObject("addUser method -" + user);
        return model;
    }

    @RequestMapping(value = "/edit", method = RequestMethod.PUT)
    public ModelAndView editUser(String user) {
        LOG.info("editUser-" + user);
        ModelAndView model = new ModelAndView("xStreamMarshallingView");
        model.addObject("editUser method -" + user);
        return model;
    }

    @RequestMapping(value = "/remove/{id}", method = RequestMethod.DELETE)
    public ModelAndView removeUser(@PathVariable String id) {
        LOG.info("removeUser-" + id);
        ModelAndView model = new ModelAndView("xStreamMarshallingView");
        model.addObject("removeUser method -" + id);
        return model;
    }
}

2.spring rest 调用：

package com.mzj.practice.rest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.web.client.RestTemplate;

/**
 * Copyright (C),HANDPAY<br>
 *
 * RestTemplate调用REST资源
 *
 * RestTemplate的getForObject完成get请求、postForObject完成post请求、put对应的完成put请求、delete完成delete请求；<br>
 * 还有execute可以执行任何请求的方法， 需要你设置RequestMethod来指定当前请求类型。 <br>
 * RestTemplate.getForObject(String url, Class<String> responseType, String... urlVariables)
 * 参数url是http请求的地址，参数Class是请求响应返回后的数据的类型，最后一个参数是请求中需要设置的参数。<br>
 *

 */
@Component
public class RESTClient {

    @Autowired
    private RestTemplate template;

    private final static String url = "http://localhost:8080/SpringRestWS/restful/";

    public String show() {
        return template.getForObject(url + "show.do", String.class, new String[] {});
    }

    public String getUserById(String id) {
        return template.getForObject(url + "get/{id}.do", String.class, id);
    }

    public String addUser(String user) {
        return template.postForObject(url + "add.do?user={user}", null, String.class, user);
    }

    public String editUser(String user) {
        template.put(url + "edit.do?user={user}", null, user);
        return user;
    }

    public String removeUser(String id) {
        template.delete(url + "/remove/{id}.do", id);
        return id;
    }
}

3.配置spring-rest.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    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.xsd">

<!--
    下面配置了xStreamMarshaller是和RESTController中的ModelAndView的view对应的。
    因为那边是用xStreamMarshaller进行编组的，所以RestTemplate这边也需要用它来解组。
    RestTemplate还指出其他的MarshallingHttpMessageConverter；
-->

<!--RestTemplate需要配置MessageConvert将返回的xml文档进行转换，解析成JavaObject：  -->
    <bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
        <property name="messageConverters">
            <list>
                <bean
                    class="org.springframework.http.converter.xml.MarshallingHttpMessageConverter">
                    <property name="marshaller" ref="xStreamMarshaller" />
                    <property name="unmarshaller" ref="xStreamMarshaller" />
                </bean>
            </list>
        </property>
    </bean>

    <bean id="xStreamMarshaller" class="org.springframework.oxm.xstream.XStreamMarshaller">
        <property name="annotatedClasses">
            <array>
            </array>
        </property>
    </bean>
</beans>

4.测试：

package com.mzj.practice.rest.test;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;

import com.mzj.practice.rest.RESTClient;

/**
 * Copyright (C),HANDPAY<br>
 *
 * RESTClient TEST
 *
 * @author muzhongjiang
 * @date 2014年10月26日
 */

@ContextConfiguration("classpath:applicationContext-*.xml")
public class RESTClientTest  extends AbstractJUnit4SpringContextTests{

    @Autowired
    private RESTClient client;

    public void testShow() {
        System.out.println(client.show());
    }

    public void testGetUserById() {
        System.out.println(client.getUserById("abc"));
    }

    public void testAddUser() {
        System.out.println(client.addUser("jack"));
    }

    public void testEditUser() {
        System.out.println(client.editUser("tom"));
    }

    public void testRemoveUser() {
        System.out.println(client.removeUser("aabb"));
    }
}
