main方法：

package com.xxx.tmp;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
public class Main {public static void main(final String[] args) {final AnnotationConfigApplicationContext applicationContext =new AnnotationConfigApplicationContext(SyncService.class);final SyncService bean = applicationContext.getBean(SyncService.class);
//        final SyncService bean = SpringContextHolder.getBean(SyncService.class);for (int i = 0; i < 100; i++) {bean.test(i);}}
}

service方法:

package com.xxx.tmp;
import org.springframework.stereotype.Component;
@Component
public class SyncService {//    @Asyncpublic void test(final int i) {System.out.println(Thread.currentThread().getName() + "——" + i);}
}

配置：

package com.xxx.tmp;import org.springframework.aop.interceptor.AsyncUncaughtExceptionHandler;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.AsyncConfigurer;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;import java.lang.reflect.Method;
import java.util.concurrent.Executor;@Configuration
@EnableAsync
@ComponentScan("com.xxx.tmp")
public class AsyncConfig implements AsyncConfigurer {@Overridepublic Executor getAsyncExecutor() {final ThreadPoolTaskExecutor threadPoolTaskExecutor = new ThreadPoolTaskExecutor();threadPoolTaskExecutor.setCorePoolSize(10);threadPoolTaskExecutor.setMaxPoolSize(50);threadPoolTaskExecutor.setQueueCapacity(50);threadPoolTaskExecutor.setKeepAliveSeconds(1);threadPoolTaskExecutor.initialize();return threadPoolTaskExecutor;}@Overridepublic AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {return new AsyncUncaughtExceptionHandler() {@Overridepublic void handleUncaughtException(final Throwable throwable, final Method method, final Object... objects) {System.out.println("出现异常啦~~~~~~");}};}
}

就可以真实启动了，无须通过test去测试
