使用Spring 线程池

    <bean id="taskExecutor" class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
        <!-- 线程池维护线程的最少数量   -->
        <property name="corePoolSize" value="3" />
        <!-- 线程池维护线程所允许的空闲时间   -->
        <property name="keepAliveSeconds" value="200" />
        <!-- 线程池维护线程的最大数量   -->
        <property name="maxPoolSize" value="5" />
        <!-- 线程池所使用的缓冲队列   -->
        <property name="queueCapacity" value="25" />
    </bean>
    
</beans>

以上为线程池的一些配置。

写了一个service，初始化线程池，并且，作为一个调用线程的接口

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import org.springframework.stereotype.Component;

@Component
public class ThreadPoolTaskService {

    private ApplicationContext ctx;
    private ThreadPoolTaskExecutor taskExecutor;
    
    public ThreadPoolTaskService () {
        ctx = new ClassPathXmlApplicationContext("threadpool.xml");
        taskExecutor = (ThreadPoolTaskExecutor) ctx.getBean("taskExecutor");
    }
    
    public void execute(Runnable runnable) {
        if (null != taskExecutor) {
            taskExecutor.execute(runnable);
        }
    }
}

再写一个runnable

public class TesetThread implements Runnable {

    private List<String> list;
    
    private TestAService testAService;
    
    public TestThread() {
        
    }
    public TestThread(List<String> list, TestAService testAService) {
        this.list = jobList;
        this.testAService = testAService;
    }
    
    @Override
    public void run() {
        
        testAService.deal(list);
    }
    
}

使用的时候

@Autowired
private ThreadPoolTaskService threadPoolTaskService;

threadPoolTaskService.execute(new TestThread(list, testAService));
