@Remotable用在需要远程调用的接口，tuscany要求java接口必须声明为remotable才可以发布为外部service

这里tuscany导入这几个依赖：

<!-- tuscany -->
<!--tuscany依赖开始-->
<dependency>
    <groupId>org.apache.tuscany.sca</groupId>
    <artifactId>tuscany-implementation-spring-runtime</artifactId>
    <version>2.0.1</version>
</dependency>
<!--https://mvnrepository.com/artifact/org.apache.tuscany.sca/tuscany-sca-api -->
<dependency>
    <groupId>org.apache.tuscany.sca</groupId>
    <artifactId>tuscany-sca-api</artifactId>
    <version>2.0.1</version>
</dependency>
<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.aggregation</groupId>
    <artifactId>tuscany-binding-rmi-runtime-aggregation</artifactId>
    <version>2.0.1</version>
</dependency>
<!--tuscany依赖结束-->

导入之后就可以正常使用tuscany的标签，在相关的service上加上@Remotable就可以发布为远程service
