Question

我从互联网上尝试了这个节俭的Java示例，如下所示。客户端未连接到服务器。我有这些：

（1）节俭定义“ add.thrift”

typedef i32 int  //typedefs to get convenient names for your types  

service AdditionService {  // defines the service to add two numbers  
        int add(1:int n1, 2:int n2), //defines a method  
}

（2）编译

thrift --gen java add.thrift

我有gen-java / AdditionServer.java文件

（3）在AdditionServiceHandler.java中实现服务接口

import org.apache.thrift.TException;  
public class AdditionServiceHandler implements AdditionService.Iface {
    @Override
    public int add(int n1, int n2) throws TException {
        return n1 + n2;
    }  
}

（4）MyServer.java

import org.apache.thrift.transport.TServerSocket;
import org.apache.thrift.transport.TServerTransport;
import org.apache.thrift.server.TServer;
import org.apache.thrift.server.TServer.Args;
import org.apache.thrift.server.TSimpleServer;
import org.apache.thrift.protocol.TBinaryProtocol;
import org.apache.thrift.protocol.TBinaryProtocol.Factory;
public class MyServer {
    public static void main(String[] args) {
        AdditionService.Processor<AdditionServiceHandler> processor =
            new AdditionService.Processor<AdditionServiceHandler>(new AdditionServiceHandler());
        try {
            TServerTransport serverTransport = new TServerSocket(9090);
            TServer server = new TSimpleServer(new Args(serverTransport).processor(processor));
            System.out.println("Starting the simple server...");
            server.serve();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

（5）AdditionClient.java

import org.apache.thrift.TException;
import org.apache.thrift.protocol.TBinaryProtocol;
import org.apache.thrift.protocol.TProtocol;
import org.apache.thrift.transport.TSocket;
import org.apache.thrift.transport.TTransport;
import org.apache.thrift.transport.TTransportException;

public class AdditionClient {
    public static void main(String[] args) {
        try {
            TTransport transport = new TSocket("localhost", 9090);
            transport.open();
            AdditionService.Client client = new AdditionService.Client(new TBinaryProtocol(transport));
            //client.ping(2012);
            System.out.println(client.add(100, 200));
            transport.close();
        } catch (TTransportException e) {
            e.printStackTrace();
        } catch (TException x) {
            x.printStackTrace();
        }
    }
}

（6）在“ mvn编译”之后，我执行了：

mvn exec:java -Dexec.mainClass="MyServer"

已打印

SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
Starting the simple server..

然后我启动客户端，它没有连接，几秒钟后，它超时并退出：

mvn exec:java -Dexec.mainClass="AdditionClient"

org.apache.thrift.transport.TTransportException: java.net.ConnectException: Operation timed out (Connection timed out)
        at org.apache.thrift.transport.TSocket.open(TSocket.java:226)

那我在哪里弄错了，怎么解决呢？

Java：简单的Thrift客户端无法连接到Thrift服务器的示例，超时
