Restlet restful 学习

首先添加 Restlet 需要的Maven Dependency:

    <dependency><groupId>org.restlet.jse</groupId><artifactId>org.restlet</artifactId><version>${restlet-version}</version></dependency><dependency><groupId>org.restlet.jee</groupId><artifactId>org.restlet.ext.servlet</artifactId><version>${restlet-version}</version></dependency>

Restlet的version：

<restlet-version>2.3.1</restlet-version>

还有tomcat的plugin：

      <plugin><groupId>org.apache.tomcat.maven</groupId><artifactId>tomcat7-maven-plugin</artifactId><version>2.2</version><configuration><!-- http port --><port>8080</port><!-- application path always starts with / --><path>/</path></configuration></plugin>

web.xml中配置Restlet的 servlet:

  <servlet><servlet-name>RestletServlet</servlet-name><servlet-class>org.restlet.ext.servlet.ServerServlet</servlet-class><init-param><!-- Application class name --><param-name>org.restlet.application</param-name><param-value>com.tch.test.restlet.HelloApplication</param-value></init-param></servlet><servlet-mapping><servlet-name>RestletServlet</servlet-name><url-pattern>/restlet/*</url-pattern></servlet-mapping>

Application实现类：

package com.tch.test.restlet;import org.restlet.Application;
import org.restlet.Restlet;
import org.restlet.routing.Router;import com.tch.test.restlet.restprovider.DreamoftchServerResource;
import com.tch.test.restlet.restprovider.HelloWorldServerResource;public class HelloApplication extends Application {@Overridepublic Restlet createInboundRoot() {Router router = new Router(getContext());router.attach("/hello", HelloWorldServerResource.class);return router; }
}

Restful 服务provider:

package com.tch.test.restlet.restprovider;import org.restlet.resource.Get;
import org.restlet.resource.ServerResource;public class HelloWorldServerResource extends ServerResource{@Getpublic String getHello() {return "Hello World, this is hello world server resource ...";}}

OK

启动tomcat： mvn tomcat7:run

浏览器访问：

http://localhost:8080/restlet/hello

http://localhost:8080/restlet/dreamoftch

就可以看到结果了。

或者通过 Restlet的 ClientResource类：

package com.tch.test.restlet;import java.io.IOException;import org.restlet.resource.ClientResource;
import org.restlet.resource.ResourceException;public class RestletTest {public static void main(String[] args) throws ResourceException, IOException  {new ClientResource("http://localhost:8080/restlet/hello").get().write(System.out);}}

从控制台输出可以看到结果。

OK, Finish ...
