远程触发Jenkins的Pipeline任务的并发问题处理

远程触发Jenkins的问题

对Jenkins服务来说，很有可能在某一时刻同时收到多个Http请求，并且这些请求都想触发同一个任务，在实际使用中发现此时Jenkins并不对每个请求都运行一次任务，接下来的实战，我们就来重现并解决此问题；

用Java代码实现多个并发请求

我们用代码来模拟同一时刻多个Http请求到达Jenkins的情况：写个Java程序，一次性发送10个Http请求，都是远程触发上一章的Jenkins任务的，参考源码如下：

package com.bolingcavalry;

import com.alibaba.fastjson.JSONObject;
import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;

public class App {
    public static void main( String[] args ) throws Exception {
        for(int i=0;i<10;i++) {
            JSONObject jsonObject = new JSONObject();
            jsonObject.put("ref", "ref-"+i);
            jsonObject.put("repositoryURL","https://github.com/zq2599/jenkinsdemo.git");
            jsonObject.put("branch", "master");

            CloseableHttpClient httpClient = HttpClients.createDefault();
            HttpPost httpPost = new HttpPost("http://192.168.133.149:32049/generic-webhook-trigger/invoke?token=token-remote-test");
            httpPost.addHeader("Content-Type", "application/json");
            httpPost.setEntity(new StringEntity(jsonObject.toJSONString()));
            CloseableHttpResponse response = httpClient.execute(httpPost);
            response.close();
            httpClient.close();

            System.out.println("response code : " + response.getStatusLine().getStatusCode() + "
");
        }
    }
}
