让SOA落地，tuscany初体验

1 安装tuscany插件 http://archive.apache.org/dist/incubator/tuscany/java/sca/1.2-incubating/updatesite/
2 建立一个java项目hello
  定义接口

package soasample;

import org.osoa.sca.annotations.Remotable;


@Remotable
public interface Hello {

	String say(String name);
}	

  定义实现类

package soasample;

public class HelloImpl implements Hello {

	@Override
	public String say(String name) {
		// TODO Auto-generated method stub
		System.out.println("Hello-->"+ "hello:" + name);
		return "hello:" + name;
	}

}

  定义文件hello.composite文件

<?xml version="1.0" encoding="UTF-8"?>
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0"
	xmlns:t="http://tuscany.apache.org/xmlns/sca/1.0"
	xmlns:c="http://hello" targetNamespace="http://hello" name="hello">
	<component name="Hello">
		<implementation.java class="soasample.HelloImpl"></implementation.java>
		<service name="Hello">
			<interface.java interface="soasample.Hello"></interface.java>
			<binding.ws></binding.ws>
		</service>
	</component>
</composite>

3 建立一个java项目first
  定义接口

package soasample;

import org.osoa.sca.annotations.Remotable;

@Remotable
public interface First {

	String first();
}

  定义实现

package soasample;

import org.osoa.sca.annotations.Reference;

public class FirstImpl implements First {
	
	private Hello hello = null;

	@Override
	public String first() {
		String say = hello.say("test");
		System.out.println("First-->"+ say);
		return say;
	}

	public Hello getHello() {
		return hello;
	}

	@Reference
	public void setHello(Hello hello) {
		this.hello = hello;
	}

}	

  定义文件first.composite文件

<?xml version="1.0" encoding="UTF-8"?>
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0"
    xmlns:t="http://tuscany.apache.org/xmlns/sca/1.0"
    xmlns:c="http://first"
    targetNamespace="http://first"
    name="first">
	<component name="First">
		<implementation.java class="soasample.FirstImpl">			
		</implementation.java>
		<reference name="hello" target="Hello">
			<interface.java interface="soasample.Hello"></interface.java>
			<binding.ws uri="http://192.168.204.1:8100/Hello"/>
                        <!--此处ip端口不同，注意看控制台信息修改一下-->
		</reference>
		<service name="First">
			<interface.java interface="soasample.First"></interface.java>			
			<binding.ws></binding.ws>
		</service>
	</component>
</composite>

4 启动，先启动hello项目，选中hello.composite文件 运行选择tuscany方式，启动好之后以同样方式启动first项目
  你可以看到eclipse启动了3个控制台
  OK，你可以以web service方式调用First，看看输出
    hello控制台
      Hello-->hello:test
    first控制台
      First-->hello:test
5 tuscany比spring等IOC容器更提升了一步，将协议层彻底分离
