1、报错时的配置类和报错结果如下图：

在这里插入图片描述2、解决方式：在配置类中实现AsyncConfigurer接口，注册taskExecutor执行任务，即可，图和代码如下：

package com.rf.springboot01.concurrentAndThread.t3;import org.springframework.aop.interceptor.AsyncUncaughtExceptionHandler;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;import org.springframework.scheduling.annotation.AsyncConfigurer;import org.springframework.scheduling.annotation.EnableAsync;import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;import java.util.concurrent.Executor;/**

        ThreadPoolTaskExecutor taskExecutor=newThreadPoolTaskExecutor();
        taskExecutor.setCorePoolSize(10);
        taskExecutor.setMaxPoolSize(80);
        taskExecutor.setQueueCapacity(100);
        taskExecutor.initialize();//如果不初始化，导致找到不到执行器return taskExecutor;}// 用于捕获异步异常@Overridepublic AsyncUncaughtExceptionHandlergetAsyncUncaughtExceptionHandler(){return null;}}

3、在重新启动，控制台输出无报错信息，如下图：
