并行常见的场景

1、并行执行多个任务；

创建工作线程任务：

package org.itdgz.asynctool;

import com.jd.platform.async.callback.ICallback;
import com.jd.platform.async.callback.IWorker;
import com.jd.platform.async.executor.timer.SystemClock;
import com.jd.platform.async.worker.WorkResult;
import com.jd.platform.async.wrapper.WorkerWrapper;

import java.util.Map;

public class ParWorker implements IWorker<String, String>, ICallback<String, String> {
   
   
    @Override
    public String action(String s, Map<String, WorkerWrapper> map) {
   
   
        try {
   
   
            Thread.sleep(1000);
        } catch (InterruptedException e) {
   
   
            e.printStackTrace();
        }
        return "result = " + SystemClock.now() + "---param = " + s + " from 0";
    }

    @Override
    public String defaultValue() {
   
   
        return "worker--default";
    }

    @Override
    public void begin() {
   
   

    }

    @Override
    public void result(boolean b, String s, WorkResult<String> workResult) {
   
   
        if (b) {
   
   
            System.out.println("callback worker success--" + SystemClock.now() + "----" + workResult.getResult()
                    + "-threadName:" +Thread.currentThread().getName());
        } else {
   
   
            System.err.println("callback worker failure--" + SystemClock.now() + "----"  + workResult.getResult()
                    + "-threadName:" +Thread.currentThread().getName());
        }
    }
}
