Question

我正在使用异步任务来处理一些大请求，我的详细信息在下面

@Configuration
@EnableAsync
public class AsyncConfiguration 
{
    @Bean(name = "asyncExecutor")
    public Executor asyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(10);
        executor.setMaxPoolSize(10);
        executor.setQueueCapacity(100);
        executor.setThreadNamePrefix("AsynchThread-");
        executor.initialize();
        return executor;
    }
}


@Service
public class AsyncService {
    @Async("Executor")
    public void  processData(User user) throws InterruptedException 
    {

        /* my business logic for each user*/

        return  ;
    }

}

这里我正在获取用户列表，它可能包含50个用户，所以在发布到异步任务之前，我想知道我有足够的队列容量来容纳50个线程，如果没有，我必须返回到调用方，说我的服务器正忙。

@RequestMapping(value = "/users", method = RequestMethod.POST)
    public void postAllUsers(@RequestBody List<User>  users) throws InterruptedException, ExecutionException 
    {

        for (List<User> user: users) 
    {
        try {
            service.processData(user);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    }

那么如何获得当前的使用率？
