spring

<!-- spring线程池 -->
    <bean id = "task" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
        <!-- 线程池维护线程的最少数量 -->
        <property name="corePoolSize" value="2"></property>
        <!-- 允许空闲时间 -->
        <property name="keepAliveSeconds" value="200"></property>
        <!-- 线程池维护线程的最大数量 -->
        <property name="maxPoolSize" value="5"></property>//配置为5，实际最大线程为maxPoolSize+1=6
        <!-- 缓存队列 -->
        <property name="queueCapacity" value="1"></property>
        <!-- 对拒绝task的处理策略 -->
        <property name="rejectedExecutionHandler">
             <bean class="java.util.concurrent.ThreadPoolExecutor$CallerRunsPolicy" />
        </property>
    </bean>

    }
    @Bean("async-redis")

        return new ThreadPoolExecutor(1, 1, 0L, TimeUnit.MILLISECONDS, new LinkedTransferQueue<>());
