Spring 方法异步执行配置与使用

@EnableAsync

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
@Documented
@Import(AsyncConfigurationSelector.class)
public @interface EnableAsync {
    Class<? extends Annotation> annotation() default Annotation.class;
    boolean proxyTargetClass() default false;
    AdviceMode mode() default AdviceMode.PROXY;
    int order() default Ordered.LOWEST_PRECEDENCE;
}

@EnableAsync 注解用于开启 Spring 对方法异步执行的能力，需要和注解@Configuration 配合使用。

@Configuration
@EnableAsync
public class AppConfig {
}

也可以自定义线程池：

@Configuration
@EnableAsync
public class AppConfig implements AsyncConfigurer {
    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(7);
        executor.setMaxPoolSize();
        executor.setQueueCapacity();
        executor.setThreadNamePrefix();
        executor.initialize();
         executor;
    }

    
     AsyncUncaughtExceptionHandler  {
          ();
    }
}
