1.配置线程池

@Slf4j
@EnableAsync
@Configuration
public class DBExecutorConfig {

    @Bean("dbExecutor")
    public Executor taskExecutorInit(){
        int coreSize = Runtime.getRuntime().availableProcessors();
        log.info("init operator db executor . cpu thread size is {}", coreSize);
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(coreSize);
        executor.setMaxPoolSize(coreSize * 2);
        executor.setQueueCapacity(200);
        executor.setKeepAliveSeconds(60);
        executor.setThreadNamePrefix("operator_db_executor");
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        return executor;
    }
}

2.使用定义好的线程池

    @Async("dbExecutor")
    public Future<String> saveReqMsg(String request){
       
        String msg= ……;
        return new AsyncResult<>(msg);
    }
