ProxyAsyncConfiguration.java源碼：

@Configuration@Role(BeanDefinition.ROLE_INFRASTRUCTURE)public class ProxyAsyncConfiguration extends AbstractAsyncConfiguration {    @Bean(name = TaskManagementConfigUtils.ASYNC_ANNOTATION_PROCESSOR_BEAN_NAME)    @Role(BeanDefinition.ROLE_INFRASTRUCTURE)    public AsyncAnnotationBeanPostProcessor asyncAdvisor() {        Assert.notNull(this.enableAsync, "@EnableAsync annotation metadata was not injected");        AsyncAnnotationBeanPostProcessor bpp = new AsyncAnnotationBeanPostProcessor();        Class<? extends Annotation> customAsyncAnnotation = this.enableAsync.getClass("annotation");        if (customAsyncAnnotation != AnnotationUtils.getDefaultValue(EnableAsync.class, "annotation")) {            bpp.setAsyncAnnotationType(customAsyncAnnotation);        }        if (this.executor != null) {            bpp.setExecutor(this.executor);        }        if (this.exceptionHandler != null) {            bpp.setExceptionHandler(this.exceptionHandler);        }        bpp.setProxyTargetClass(this.enableAsync.getBoolean("proxyTargetClass"));        bpp.setOrder(this.enableAsync.<Integer>getNumber("order"));        return bpp;    }}

 

AbstractAsyncConfiguration.java源碼：

    @Autowired(required = false)    void setConfigurers(Collection<AsyncConfigurer> configurers) {        if (CollectionUtils.isEmpty(configurers)) {            return;        }        if (configurers.size() > 1) {            throw new IllegalStateException("Only one AsyncConfigurer may exist");        }        AsyncConfigurer configurer = configurers.iterator().next();        this.executor = configurer.getAsyncExecutor();        this.exceptionHandler = configurer.getAsyncUncaughtExceptionHandler();    }

 

看AsyncDefaultAutoConfiguration.java源碼：

public class AsyncDefaultAutoConfiguration {    @Autowired private BeanFactory beanFactory;    @Configuration    @ConditionalOnMissingBean(AsyncConfigurer.class)    @ConditionalOnProperty(value = "spring.sleuth.async.configurer.enabled", matchIfMissing = true)    static class DefaultAsyncConfigurerSupport extends AsyncConfigurerSupport {        @Autowired private BeanFactory beanFactory;        @Override        public Executor getAsyncExecutor() {            return new LazyTraceExecutor(this.beanFactory, new SimpleAsyncTaskExecutor());        }    }
