Question

我为部署在WSO2ESB上的WebService生成了一个Java客户端，通过此客户端，我尝试使用循环和Sleep发送周期性请求，但我收到了相同的响应（值，WS接收请求的时间，发送回复的时间）!!

我有Stub类，我在Main Class中调用的My Java Client是：

package org.wso2.cs.helloservices;
import java.rmi.RemoteException;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Calendar;
import org.wso2.cs.helloservices.HelloProviderStub.SayHello;
import org.wso2.cs.helloservices.HelloProviderStub.SayHelloResponse;

public class Consumer {

public ArrayList <SayHelloResponse> consumer(int requestsNumber, int sleep, int reliability) throws 

RemoteException, InterruptedException{
    ArrayList <SayHelloResponse> listResp = new ArrayList<SayHelloResponse>();

    HelloProviderStub Stub= new HelloProviderStub();

    for (int i=0; i<requestsNumber; i++){
        Thread.sleep(3000);
        SayHello request=new SayHello();
        SimpleDateFormat dateFormat = new SimpleDateFormat("mm:ss");

        request.setSleep(sleep);
        request.setReliability(reliability);
        SayHelloResponse resp=Stub.sayHello(request);
        listResp.add(resp);
    }
    return listResp;
  }
 }

例如，回复是：

Result of Request: 1
---------------------
Receiving Request : 2013:01:24:21:22:30:00935
Sending Response  : 2013:01:24:21:22:31:00935
Response          : Test

Result of Request: 2
---------------------
Receiving Request : 2013:01:24:21:22:30:00935
Sending Response  : 2013:01:24:21:22:31:00935
Response          : Test

请提出任何建议。

Answer 1

可能是缓存生成的响应看起来相同。如果允许此功能正常运行，则服务将打开以进行DoS（拒绝服务）攻击。

WSO2和Java客户端定期请求
