Spark的Service类中有一个方法（javadoc），用于设置你的Spark服务器监听的IP地址。
> public Service ipAddress(String ipAddress)
>
> 设置Spark应该监听的IP地址。如果没有调用此方法，默认地址为'0.0.0.0'。必须在进行任何路由映射之前调用此方法。
如果你想要这些应用在同一个JVM中运行，似乎可以通过实例化多个Service对象来实现。Javadoc中提到：
> Service代表了Spark服务器的“会话”。如果用户想在他的应用程序中使用多个'Sparks'，则应该静态导入并使用方法ignite()来创建实例。
英文:
There is a method in the Spark Service class (javadoc) that sets the IP address that your Spark server listens on.
> public Service ipAddress(String ipAddress)
>
> Set the IP address that Spark should listen on. If not called the default address is '0.0.0.0'. This has to be called before any route mapping is done.
If you wanted these apps to run in the same JVM, it looks like you do this by instantiating multiple Service onjects. The javadoc says:
> Service represents a Spark server "session". If a user wants multiple 'Sparks' in his application the method ignite() should be statically imported and used to create instances.

Use Spark.ipAddress("我的IP地址");
Reference: javadoc

Use Spark.ipAddress("my.IP.address");
