Spring线程池配置

方法一：

<!-- 异步线程池 -->
<bean id="taskExecutor"
class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
<!-- 核心线程数 -->
<property name="corePoolSize" value="10" />
<!-- 最大线程数 -->
<property name="maxPoolSize" value="100" />
<!-- 队列最大长度 >=mainExecutor.maxSize -->
<property name="queueCapacity" value="1000" />
<!-- 线程池维护线程所允许的空闲时间 -->
<property name="keepAliveSeconds" value="300" />
<!-- 线程池对拒绝任务(无线程可用)的处理策略 -->
<property name="rejectedExecutionHandler">
<bean class="java.util.concurrent.ThreadPoolExecutor$CallerRunsPolicy" />
</property>
</bean>

方法二：

<!-- 用于支持并发批量的线程池 -->
<task:executor id="asyncTaskExecutor" pool-size="#{env['batchTaskPoolSize'] ?: 16}"/>

测试

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.task.TaskExecutor;


public class ThreadPoolTest {
@Autowired
private TaskExecutor taskExecutor;// 线程池


// 将创建的线程添加到线程池中
public void test() throws Exception {
for (int i = 0; i < 10; i++) {
this.taskExecutor.execute(new AppContentDataPushThread());
}
}


class AppContentDataPushThread implements Runnable {


public AppContentDataPushThread() {
}


@Override
public void run() {
System.out.println("执行线程");
}
}
}
