<div class =“post-text”itemprop =“text”> 看看类型 <a href="http://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/scheduling/annotation/AsyncConfigurer.html" rel="nofollow noreferrer"> <code> AsyncConfigurer </code> </A> ， <a href="http://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/scheduling/annotation/AsyncConfigurerSupport.html" rel="nofollow noreferrer"> <code> AsyncConfigurerSupport </code> </A> ，和 <a href="http://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/scheduling/annotation/SchedulingConfigurer.html" rel="nofollow noreferrer"> <code> SchedulingConfigurer </code> </A> 。它们是您可以用来增强您的帮助类型 <code> @Configuration </code> 具有异步/调度配置的类。 所有这些，以及javadoc <a href="http://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/scheduling/annotation/EnableAsync.html" rel="nofollow noreferrer"> <code> @EnabledAsync </code> </A> ，您将找到设置异步/调度所需的所有设置方法 <code> @Configuration </code> 类。 给出的例子等同于 <pre> <code> @Configuration @EnableAsync public class AppConfig implements AsyncConfigurer { @Bean public MyAsyncBean asyncBean() { return new MyAsyncBean(); } @Override public Executor getAsyncExecutor() { ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor(); executor.setCorePoolSize(7); executor.setMaxPoolSize(42); executor.setQueueCapacity(11); executor.setThreadNamePrefix("MyExecutor-"); executor.initialize(); return executor; } @Override public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() { return new MyAsyncUncaughtExceptionHandler(); } } </code> </pre> 同 <pre> <code> <beans> <task:annotation-driven executor="myExecutor" exception-handler="exceptionHandler"/> <task:executor id="myExecutor" pool-size="7-42" queue-capacity="11"/> <bean id="asyncBean" class="com.foo.MyAsyncBean"/> <bean id="exceptionHandler" class="com.foo.MyAsyncUncaughtExceptionHandler"/> </beans> </code> </pre> <code> SchedulingConfigurer </code> 有一个类似的设置 <code> task:scheduler </code> 。 </DIV>

<div class =“post-text”itemprop =“text”> 如果你想要更精细的控制，你可以另外实现 <code> SchedulingConfigurer </code> 和/或 <code> AsyncConfigurer </code> 接口。 如下， 请注意游泳池， <pre> <code> @Configuration @EnableScheduling public class CronConfig implements SchedulingConfigurer{ @Override public void configureTasks(ScheduledTaskRegistrar taskRegistrar) { taskRegistrar.setScheduler(taskExecutor()); } @Bean(destroyMethod="shutdown") public Executor taskExecutor() { return Executors.newScheduledThreadPool(10); } } </code> </pre> 对于Asyncs， <pre> <code> @Configuration @EnableAsync public class AsyncConfig implements AsyncConfigurer { @Override public Executor getAsyncExecutor() { ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor(); executor.setCorePoolSize(5); executor.setMaxPoolSize(10); executor.setQueueCapacity(100); executor.initialize(); return executor; } @Override public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() { return new SimpleAsyncUncaughtExceptionHandler(); } } </code> </pre> 注意 <code> @EnableAsync </code> 和 <code> @EnableScheduling </code> 必须在那里工作。 </DIV>
