GAEA-58服务端初始化生成的服务“动态代理类”和“代理工厂类”

以服务实现类NewsService为例：


思考：不明白作者为什么要这样生成服务代理类，根据服务名用反射获取服务实例不行吗？性能貌似也不低啊。 还是说为了热部署才这么做的，我能想到的只有这么个需求才会这么做。

//动态代理工厂类

public class  ProxyFactory1439795760927 implements IProxyFactory{

	private IProxyStub proxyNewsServicedemo =null;
	private IProxyStub demo1 =null;
	private IProxyStub demo2 =null;
	
	public void IProxyFactory(java.util.List $1);
	{	
		proxyNewsServicedemo=(com.bj58.spat.gaea.server.contract.context.IProxyStub)$1.get(0);
		demo1=(com.bj58.spat.gaea.server.contract.context.IProxyStub)$1.get(1);
		demo2=(com.bj58.spat.gaea.server.contract.context.IProxyStub)$1.get(2);
	}
	
	//动态生成代理工程的getProxy方法
	public IProxyStub getProxy(String lookup) {
	
		if(lookup.equalsIgnoreCase("NewsService"))
			{
				return proxyNewsServicedemo;
			}
			
			if(..){
				..
			}
			if(..){
				..
			}
			if(..){
				..
			}
			return null;
		}
	}
