ThreadPoolExecutor使用实例

使用场景：需要同时创建多个线程去访问某一接口，并将返回数据进行组装

1. 创建ThreadPoolExecutor，切记创建在类的方法之外，这样就不会调用一次方法，创建一个ThreadPoolExecutor

private final static ThreadPoolExecutor executor = new ThreadPoolExecutor(10, 30, 2000, TimeUnit.MILLISECONDS,new ArrayBlockingQueue<Runnable>(100));

具体参数含义、原理、设置自行百度

2. 创建要执行任务的线程类

 public class ExcuteTask implements Callable<BizResult<List<BudgetDTO>>> {
    private BudgetForm form;
    private BudgetService budgetService;

    public ExcuteTask(BudgetForm form, BudgetService budgetService) {
        this.form = form;
        this.budgetService = budgetService;
    }

    @Override
    public BizResult<List<BudgetDTO>> call() {
        return budgetService.que
