SpringBoot报错Action: Consider defining a bean named 'webMvcAsyncTaskExecutor' in your configuration

前言：

往SpringBoot2.0项目中，加入webSocket，往config中加入注解@EnableWebSocketMessageBroker，项目无法启动，报错如下：

Action: Consider defining a bean named 'webMvcAsyncTaskExecutor' in your configuration。

解决方法：

在你的Application加入，如下配置，再起启动，就启动起来了.

@SpringBootApplication
public class WsApplication {

    public static void main(String[] args) {
        SpringApplication.run(WsApplication.class, args);
    }
	
	//加入如下配置
    @Bean({"threadPoolTaskExecutor", "webMvcAsyncTaskExecutor"})
    public ThreadPoolTaskExecutor threadPoolTaskExecutor() {
        return new ThreadPoolTaskExecutor();
    }
}
