Spring之rest full 服务搭建

rest full api使用方便能够很好的弱耦合，那么spring对rest full服务很好的支持。

依赖的jar：

<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-web</artifactId>
	<version>4.1.0.RELEASE</version>
</dependency>
<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-webmvc</artifactId>
	<version>4.1.0.RELEASE</version>
</dependency>

web.xml配置：

<servlet>
	<servlet-name>spring</servlet-name>
	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
	<init-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:spring-mvc.xml</param-value>
	</init-param>
	<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
	<servlet-name>spring</servlet-name>
	<url-pattern>/</url-pattern>
</servlet-mapping>
<context-param>
	<param-name>contextConfigLocation</param-name>
	<param-value>classpath:spring-admin.xml</param-value>
</context-param>
<listener>
	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<listener>
	<listener-class>
		org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>

spring-mvc.xml：

<mvc:resources mapping="/static/**" location="/static/" />

<mvc:annotation-driven>
	<mvc:message-converters>
		<bean class="org.springframework.http.converter.StringHttpMessageConverter" />
		<bean
			class="org.springframework.http.converter.ResourceHttpMessageConverter" />
		<bean
			class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">

			<property name="supportedMediaTypes" value="application/json" />
		</bean>
	</mvc:message-converters>
</mvc:annotation-driven>

<context:component-scan base-package="com.linkrmb" />
<bean
	class="org.springframework.web.servlet.view.InternalResourceViewResolver"
	p:prefix="/WEB-INF/jsp/" p:suffix=".jsp" />

rest api相关的控制层代码：

@RestController  
@RequestMapping("/api")
public class ApiController extends BaseController {
	private Logger log = LoggerFactory.getLogger(ApiController.class);

	@RequestMapping(value = "/{id}", method = RequestMethod.GET)
	@ResponseBody
	public Item get(@PathVariable String id, HttpServletRequest request) {
		Item item = new Item();
		item.setId(id);
		item.setName("name");
		return item;
	}

	@RequestMapping(method = RequestMethod.POST)
	@ResponseBody
	public void post(Item item, HttpServletRequest request) {
		log.info("post item:{}", item.toString());
	}

	@RequestMapping(method = RequestMethod.PUT,consumes=MediaType.APPLICATION_JSON_VALUE,produces=MediaType.APPLICATION_JSON_VALUE)
	@ResponseBody
	public void put(@RequestBody Item item, HttpServletRequest request) {
		log.info("put item:{}", item.toString());
	}

	@RequestMapping(value = "/{id}", method = RequestMethod.DELETE)
	@ResponseBody
	public void delete(@PathVariable String id, HttpServletRequest request) {
		log.info("delete id:{}", id);
	}

}
