Java 从Esper开始+；插座

我是Esper的新手，我想得到一些帮助。我已经设法将Esper与CSV文件一起使用，但现在我需要使用Java对象作为通过套接字发送的事件，并且我在Internet上找不到简单的示例作为指南

有没有人可以举一些简单的例子

不管怎样，我让这里的代码，我试图使工作。当我运行它时，什么也没有发生，似乎套接字连接不起作用

服务器类（它还包含事件类）。支持发送以下事件：

import java.io.* ;
import java.net.* ;

class Server {

static final int PORT=5002;

    public Server( ) {
        try {
            ServerSocket skServer = new ServerSocket( PORT );
            System.out.println("Listening at " + PORT );
            Socket skClient = skServer.accept();        
            System.out.println("Serving to Esper");
            OutputStream aux = skClient.getOutputStream();
            ObjectOutputStream flux = new ObjectOutputStream( aux );
            int i = 0;
            while (i<10) {
                flux.writeObject( new MeteoEvent(i,"A") );
                i++;
                }
            flux.flush();
            skClient.close();
            System.out.println("End of transmission");
            } catch( Exception e ) {
            System.out.println( e.getMessage() );
        }
    }

    public static void main( String[] arg ) {
        new Server();
    }

    class MeteoEvent{

        private int sensorId;
        private String GeoArea;

        public MeteoEvent() {
        }

        public MeteoEvent(int sensorid, String geoarea) {
            this.sensorId = sensorid;
            this.GeoArea = geoarea;
        }

        public int getSensorId() {
            return sensorId;
        }

        public void setSensorId(int sensorId) {
            this.sensorId = sensorId;
        }

        public String getGeoArea() {
            return GeoArea;
        }

        public void setGeoArea(String geoArea) {
            GeoArea = geoArea;
        }   
    }
}

import java.io.*；
导入java.net。*；
类服务器{
静态最终int端口=5002；
公共服务器（）{
试一试{
ServerSocket skServer=新的ServerSocket（端口）；
System.out.println（“在“+端口侦听”）；
套接字skClient=skServer.accept（）；
System.out.println（“服务于Esper”）；
OutputStream aux=skClient.getOutputStream（）；
ObjectOutputStream流量=新的ObjectOutputStream（aux）；
int i=0；
虽然（我问题解决了！Esper开发列表非常有用。我通过位于的测试类学习了如何使用Esper+套接字

致以最良好的祝愿
