spring boot 异步线程池

启动类：@EnableAsync

方法：@Async("asyncPromiseExecutor")

 

启动类：

@Bean
public Executor asyncPromiseExecutor() {
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
//配置核心线程数
executor.setCorePoolSize(5);
//配置最大线程数
executor.setMaxPoolSize(10);
//配置队列大小
executor.setQueueCapacity(99999);
//配置线程池中的线程的名称前缀
executor.setThreadNamePrefix("async-promise-");

/**
* rejection-policy：当pool已经达到max size的时候，如何处理新任务
* CALLER_RUNS：不在新线程中执行任务，而是有调用者所在的线程来执行
*/

 executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());

//初始化执行器
executor.initialize();
return executor;
}

 

@Component
public class FileUpload {
/** 配置文件 */
@Autowired
private FormsOpenapiConfig config;

@Async("asyncPromiseExecutor")
public void uploadToAliOss(String imgStr, String base64Str) {

}
}
