Spring Async ThreadPoolTaskScheduler not initialized

提问by small_ticket

I'm trying to use Async annotation in Spring but I'm getting

我正在尝试在 Spring 中使用 Async 注释，但我得到了

java.lang.IllegalStateException: ThreadPoolTaskScheduler not initialized

error, when I try to run the method marked as Async. The following is the configuration for Async:

错误，当我尝试运行标记为异步的方法时。以下是 Async 的配置：

@EnableScheduling
@EnableAsync
@Configuration 
public class SchedulingConfiguration implements AsyncConfigurer{

    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
        scheduler.setPoolSize(10);
        return scheduler;
    }

}

and the following is the declaration of async method.

以下是异步方法的声明。

@Async
@Transactional(value = "baseTransactionManager", isolation = Isolation.READ_COMMITTED)
public void foo(Bar bar) {// some code here}

What am I missing in here?

我在这里缺少什么？

Thanks in advance.

提前致谢。

You have to explicitly call scheduler.initialize()after setting all properties but before returning the scheduler.

您必须scheduler.initialize()在设置所有属性之后但在返回调度程序之前显式调用。
