main方法:
java
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:
java
package com.xxx.tmp;
import org.springframework.stereotype.Component;
@Component
public class SyncService {
// @Async
public void test(final int i) {
System.out.println(Thread.currentThread().getName() + "------" + i);
}
}
配置:
java
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 {
@Override
public Executor getAsyncExecutor() {
final ThreadPoolTaskExecutor threadPoolTaskExecutor = new ThreadPoolTaskExecutor();
threadPoolTaskExecutor.setCorePoolSize(10);
threadPoolTaskExecutor.setMaxPoolSize(50);
threadPoolTaskExecutor.setQueueCapacity(50);
threadPoolTaskExecutor.setKeepAliveSeconds(1);
threadPoolTaskExecutor.initialize();
return threadPoolTaskExecutor;
}
@Override
public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
return new AsyncUncaughtExceptionHandler() {
@Override
public 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
