Java启动DataX数据同步，如何终止/停止/中断同步数据任务

Java启动DataX数据同步，如何终止/停止/中断同步数据任务:

1、找到datax的core模块找到类：ProcessInnerScheduler.java，将taskGroupContainerExecutorService对象存起来，
   需要中断数据同步任务时，取出对象调用shutdownNow()方法；


2、代码改造如下：

@Override
public void startAllTaskGroup(List<Configuration> configurations) {
    this.taskGroupContainerExecutorService = Executors.newFixedThreadPool(configurations.size());

    for (Configuration taskGroupConfiguration : configurations)  {
        TaskGroupContainerRunner taskGroupContainerRunner = newTaskGroupContainerRunner(taskGroupConfiguration);
        this.taskGroupContainerExecutorService.execute(taskGroupContainerRunner);
        //*************************************自定义代码，记录taskGroupContainerExecutorService，用于终止任务*************************************
        ThreadPoolUtil.dataxTaskExecutorServiceMap.put(taskGroupConfiguration.getInt(CoreConstant.DATAX_CORE_CONTAINER_JOB_ID),
        this.taskGroupContainerExecutorService);
    }

    this.taskGroupContainerExecutorService.shutdown();
}


3、终止datax同步数据任务，代码如下：

/**
 * 终止datax同步服务
 *
 * @param taskId
 * @return
 */
public static boolean cancelDataxTaskExecutorService(Integer taskId) {
    boolean cancelResult = false;
    try {
        ExecutorService executorService = dataxTaskExecutorServiceMap.get(taskId);
        if (executorService != null) {
            executorService.shutdownNow();
            dataxTaskExecutorServiceMap.remove(taskId);
            LogCacheUtil.setLogList(taskId, "强制终止同步数据任务.");
        }
        cancelResult = true;
    } catch (Exception e) {
        LogCacheUtil.setLogList(taskId, "强制终止同步数据任务失败：" + e);
        e.printStackTrace();
    }
    return cancelResult;
}
