用Spring MVC搭建REST风格的服务

什么都不说了，直接上代码。

我使用Maven管理项目，JDK为1.7，Tomcat为7.0

Maven配置如下：

<dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-aop</artifactId>        <version>3.2.6.RELEASE</version></dependency><dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-beans</artifactId>        <version>3.2.6.RELEASE</version></dependency><dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-context</artifactId>        <version>3.2.6.RELEASE</version></dependency><dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-core</artifactId>        <version>3.2.6.RELEASE</version></dependency><dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-web</artifactId>        <version>3.2.6.RELEASE</version></dependency><dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-webmvc</artifactId>        <version>3.2.6.RELEASE</version></dependency><dependency>        <groupId>org.springframework</groupId>        <artifactId>spring-oxm</artifactId>        <version>3.2.6.RELEASE</version></dependency><!-- Servlet --><dependency>        <groupId>javax.servlet</groupId>        <artifactId>servlet-api</artifactId>        <version>2.5</version></dependency><dependency>        <groupId>javax.servlet.jsp</groupId>        <artifactId>jsp-api</artifactId>        <version>2.2</version>        <scope>provided</scope></dependency><dependency>        <groupId>javax.servlet</groupId>        <artifactId>jstl</artifactId>        <version>1.2</version></dependency><!-- for json --><dependency>        <groupId>org.codehaus.jackson</groupId>        <artifactId>jackson-core-asl</artifactId>        <version>1.8.4</version></dependency><dependency>        <groupId>org.codehaus.jackson</groupId>        <artifactId>jackson-mapper-asl</artifactId>        <version>1.8.4</version></dependency><!-- for xml --><dependency>        <groupId>com.thoughtworks.xstream</groupId>        <artifactId>xstream</artifactId>        <version>1.4.7</version></dependency>

web.xml配置如下：

<!-- Servlet that dispatches request to registered handlers (Controller implementations). --><servlet><servlet-name>games</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class><init-param><param-name>contextConfigLocation</param-name><param-value>classpath:config/mvc-core-config.xml</param-value></init-param><load-on-startup>1</load-on-startup></servlet><servlet-mapping><servlet-name>games</servlet-name><url-pattern>/</url-pattern></servlet-mapping><!-- 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>httpMethodFilter</filter-name><filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class></filter><filter-mapping><filter-name>httpMethodFilter</filter-name><servlet-name>games</servlet-name></filter-mapping>

mvc-core-config.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"        xmlns:context="http://www.springframework.org/schema/context"        xmlns:mvc="http://www.springframework.org/schema/mvc"        xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd                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-3.2.xsd">        <!-- 启用spring mvc 注解，这个可以不配置。Spring在context:component-scan已经默认了 -->        <!-- <context:annotation-config /> -->        <!-- 扫描action包，应用Spring的注解 -->        <context:component-scan base-package="com.tongbu.games.web" />        <!-- 指定内容协商管理器的bean -->        <mvc:annotation-driven                content-negotiation-manager="contentNegotiationManager">        </mvc:annotation-driven>        <!-- 以下配置SpringMVC的拦截器 -->        <mvc:interceptors>                <bean id="requestResponseInterceptor"                        class="com.tongbu.games.basic.iterceptor.RequestResponseInterceptor"></bean>        </mvc:interceptors>        <!-- 这样静态资源就可以访问了 -->        <mvc:default-servlet-handler />        <!-- Spring MVC的视图配置 -->        <import resource="mvc-view-config.xml" />        <!-- message处理见Spring例子 -->        <bean id="messageSource"                class="org.springframework.context.support.ResourceBundleMessageSource"                p:basename="messages/messages" />        <!-- 异常处理见Spring例子 -->        <!-- Mapping exception to the handler view -->        <bean id="exceptionResolver"                class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">                <property name="exceptionMappings">                        <props>                        </props>                </property>        </bean></beans>

mvc-view-config.xml配置如下：

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:c="http://www.springframework.org/schema/c"xmlns:p="http://www.springframework.org/schema/p"xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"><!-- 配置内容协商视图解析 --><bean id="contentNegotiatingViewResolver"class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver"><!-- 设置内容协商管理器 --><property name="contentNegotiationManager" ref="contentNegotiationManager"></property><!-- 设置默认视图 --><property name="defaultViews"><list><ref bean="mappingJacksonJsonView" /><ref bean="marshallingView" /></list></property><!-- 设置视图解析器 --><property name="viewResolvers"><list><ref bean="defalutViewResolver" /></list></property></bean><bean id="defalutViewResolver"class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/view"></property><property name="suffix" value=".jsp"></property></bean><!-- JSON视图 --><bean id="mappingJacksonJsonView"class="org.springframework.web.servlet.view.json.MappingJacksonJsonView"></bean><!-- XML视图 --><bean id="marshallingView"class="org.springframework.web.servlet.view.xml.MarshallingView"><property name="marshaller"><bean class="org.springframework.oxm.xstream.XStreamMarshaller"></bean></property></bean><bean id="contentNegotiationManager"class="org.springframework.web.accept.ContentNegotiationManagerFactoryBean"><property name="mediaTypes"><props><prop key="json">application/json;charset=utf-8</prop><prop key="xml">application/xml;charset=utf-8</prop><prop key="do">application/json;charset=utf-8</prop></props></property><property name="ignoreAcceptHeader" value="true"></property><!-- 设置默认的 ContentType为application/json--><property name="defaultContentType" value="application/json"></property></bean></beans>

Controller代码如下：

import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;import com.tongbu.games.web.BaseController;@Controller@RequestMapping("/testController")public class TestController extends BaseController {@RequestMapping("/test")public ModelAndView test(){System.out.println(getRequest().getParameter("id"));ModelAndView mav = new ModelAndView();mav.addObject(getRequest().getParameter("id"));return mav;}}
