Tuscany2.0构建RMI服务

一、需要引入的jar包：

     <dependencies>

       <!-- tuscany rmi -->

       <dependency>

           <groupId> org.apache.tuscany.sca</groupId >

            <artifactId> tuscany-base-runtime </artifactId>

           <version> 2.0.1</ version>

       </dependency>

       <dependency>

           <groupId> org.apache.tuscany.sca</groupId >

           <artifactId> tuscany-binding- rmi-runtime</ artifactId>

           <version> 2.0.1</ version>

            <scope> runtime</ scope>

       </dependency>

       <dependency>

           <groupId> org.apache.tuscany.sca</groupId >

           <artifactId> tuscany-implementation-spring-runtime </artifactId>

           <version> 2.0.1</ version>

       </dependency>

     </dependencies >

二、定义接口和实现：

@Remotable

public interface HelloWorld {

    String sayHello(String name);

}

public class HelloWorldImpl implements HelloWorld {

    public String sayHello(String name) {

        return "Hello " + name;

    }

}

三、定义composite配置文件：

helloworld.composite文件

<?xml version= "1.0" encoding ="UTF-8"?>

<composite xmlns="http://docs.oasis-open.org/ns/opencsa/sca/200912"

      xmlns:tuscany="http://tuscany.apache.org/xmlns/sca/1.1"

      targetNamespace="http://hello" xmlns:xsd="http://www.w3.org/2001/XMLSchema"

      name= "helloworld-contribution" >

     <component name="HelloWorldComponent">

           <implementation.spring location="helloworld-context.xml" />

           <service name= "HelloworldService">

               <tuscany:binding.rmi uri="rmi://localhost:8085/HelloworldService" />

           </service>

     </component >

</composite>

helloworld-context.xml文件内容

<?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:sca="http://docs.oasis-open.org/ns/opencsa/sca-j/spring/200810"

      xsi:schemaLocation="http://www.springframework.org/schema/beans

     http://www.springframework.org/schema/beans/spring-beans.xsd       

     http://www.springframework.org/schema/sca

     http://www.osoa.org/xmlns/sca/1.0/spring-sca.xsd" >

     <sca:service name="HelloworldService" target="helloworldService" />

     <bean id="helloworldService" class="com.solidwang.tuscany.HelloWorldImpl" />

</beans>

四、定义服务启动类：

public class ServerStart {

    @Test

    public void testSayHello() throws NoSuchServiceException, IOException, InterruptedException {

        Node node = NodeFactory.newInstance().createNode( "helloworld.composite");

        node.start();

        while (true ) {

            TimeUnit. SECONDS.sleep(Long.MAX_VALUE);

        }

    }

}

五、RMI远程调用测试：

public class RmiTest {

    public static void main(String[] args) throws MalformedURLException, RemoteException, NotBoundException {

        HelloWorld h = (HelloWorld) Naming.lookup("//localhost:8085/HelloworldService");

        System. out.println("h=" + h.sayHello("solid......" ));

    }

}
