Service的方法上使用了@Async注解,如果使该注解起作用,则需要在主程序上添加@EnableAsync注解。 @SpringBootApplication@EnableAsyncpublic class SpringBoot01CacheApplication {public static void main(String[] args) {SpringApplication.run(SpringBoot01CacheApplication.class, args);}} 浏览器发起请求,控制台打印如下:...
* // 将方法标记为异步执行 * Can also be used at the type level, in which case all of the type's methods are * considered as asynchronous. *// 也可以在类型级别使用,在这种情况下,所有类型的方法都被认为是异步的。 * In terms of target method signatures, any parameter types are supported....
SpringBoot 整合异步任务 第一步:在启动类添加开启异步任务注解第二步:新建一个异步任务类,使用@Component注解将类交给Spring管理,@Async表示该方法启用异步方式 3、test包新建测试类执行结果如下: 从结果看来异步任务开启成功。你们也可以将@Async注解从方法上删除后测试看下效果,是没有了异步效果的,我这里就不展示...
In this tutorial, we’ll explore theasynchronous execution support in Springand the@Asyncannotation. Simply put, annotating a method of a bean with@Asyncwill execute itin a separate thread.In other words, the caller will not wait to complete the called method. One interesting aspect of Spring ...

spring boot中使用@Async失效 场景:在service中用户新增的方法中调用接口上传数据到其他库的接口,在新增方法上使用了@Transactional,在上传数据方法上使用了@Async,然后发现@Async注解不生效。 解决方案:不要直接在service用户新增中调用上传接口,改为在controller中即可。 代码如下: service层 controller层 使用@Async需要...
