Java 配置全局线程池出错

错误内容：

Unsatisfied dependency expressed through field 'AAAAAAManager'; nested exception
is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'AAAAAAManagerImpl':
Unsatisfied dependency expressed through field 'globalThreadPoolExecutor'; nested exception is org.springframework.beans
.factory.NoSuchBeanDefinitionException: No qualifying bean of type
'java.util.concurrent.ThreadPoolExecutor' available: expected at least 1 bean which qualifies as autowire candidate.
Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

 

解决：

在设置全局线程池中，需要在类开始位置设置：@Configuration注解

 

 

globalThreadPoolExecutor函数需要设置 Bean注解

@Bean
ThreadPoolExecutor globalThreadPoolExecutor(){
    return new ThreadPoolExecutor(corePoolSize,
            maximumPoolSize,
            keepAliveTime,
            TimeUnit.SECONDS,
            new ArrayBlockingQueue<>(blockingQueueSize),
            Executors.defaultThreadFactory(),
            new ThreadPoolExecutor.DiscardPolicy());
}
