Description:

Field taskScheduler in com.nowcoder.community.event.EventConsumer required a bean of type 'org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler' that could not be found.

	- @org.springframework.beans.factory.annotation.Autowired(required=true)


Action:

Disconnected from the target VM, address: '127.0.0.1:50354', transport: 'socket'

解决方法

项目中加一个类。

import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.EnableScheduling;

@Configuration
@EnableScheduling
//@EnableAsync		//使用@EnableAsync来开启异步的支持，使用@Async来对某个方法进行异步执行。
public class ThreadPoolConfig {
//不加这个配置类（配置类的名字无所谓）和@EnableScheduling注解,那么ThreadPoolTaskScheduler就无法注入（@Autowired），即无法初始化，无法得到一个ThreadPoolTaskScheduler的对象
}
