    问题解决了,
    添加了config文件就好了
     

    /***CreatedbyAdapterCaton2017/10/12.*/@Configuration@ComponentScan("com.wcdy.service")@EnableAsync//开启异步任务支持publicclassTaskExecutorConfigimplementsAsyncConfigurer{@OverridepublicExecutorgetAsyncExecutor(){//实现AsyncConfigurer接口并重写getAsyncExecutor方法,并返回一个ThreadPoolTaskExecutor,这样我们就获得了一个基于线程池TaskExecutorThreadPoolTaskExecutortaskExecutor=newThreadPoolTaskExecutor();taskExecutor.setCorePoolSize(10);taskExecutor.setMaxPoolSize(80);taskExecutor.setQueueCapacity(100);taskExecutor.initialize();returntaskExecutor;}@OverridepublicAsyncUncaughtExceptionHandlergetAsyncUncaughtExceptionHandler(){returnnull;}}

     

    重写了getAsyncExecutor方法n自定义线程池关键@ComponentScan("com.wcdy.service")扫描了异步任务的包,异步获得了TaskExecutor就没报错了

    启用配置

    @EnableAsync
    这个在WcdyApplication就注解了
