SpringBoot 配置使用ThreadPoolTaskExecutor 线程池

 1.添加配置文件

@Configuration
@EnableAsync
public class SpringThreadPoolExecutorConfig {

    @Bean(name = "threadPoolTaskExecutor")
    public ThreadPoolTaskExecutor threadPoolTaskExecutor() {
        ThreadPoolTaskExecutor pool = new ThreadPoolTaskExecutor();
        pool.setKeepAliveSeconds(300);
        //核心线程池数
        pool.setCorePoolSize(50);
        //最大线程
        pool.setMaxPoolSize(100);
        //队列容量
        pool.setQueueCapacity(1000);
        //队列满，线程被拒绝执行策略
        pool.setRejectedExecutionHandler(new java.util.concurrent.ThreadPoolExecutor.CallerRunsPolicy());
        pool.setThreadNamePrefix("aaaa-common-support-service--");
        return pool;
    }
}

2.使用

@Slf4j
@Service("AAAAAService")
public class AAAAAServiceImpl implements AAAAAService {


	@Autowired
	private ThreadPoolTaskExecutor threadPoolTaskExecutor;


	@Override
	public List<String> queryUserByGivenname(String txNo, String givenname)
			throws ParamInvalidException {	
	
			threadPoolTaskExecutor.execute(()->{

				log.info("-------txNO[{}],givename[{}]", txNo,givenname);
			
			});
		
		return null;
	}

}
