2.controller使用

package com.avtrace.nlc.nms.listener;

import javax.annotation.Resource;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.Session;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.jms.listener.SessionAwareMessageListener;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

/**

@Controller
@RequestMapping("/test")
public class test implements SessionAwareMessageListener<Message> {
Logger LOG = LoggerFactory.getLogger(test.class);
@Resource(name = "taskExecutor")
private ThreadPoolTaskExecutor taskExecutor;
@RequestMapping("/execute")
@ResponseBody
@Override
public void onMessage(Message message, Session session) throws JMSException {
taskExecutor.execute(new Runnable(){

public void run() {
try {
LOG.info("执行线程任务开始前");
Thread.currentThread().sleep(1000);
if (LOG.isDebugEnabled()) {
LOG.info("执行线程任务结束");
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}

});

//设置线程的存活时间
taskExecutor.setKeepAliveSeconds(60);
}

}

3、cmd f: (因为我把ad.exe放到f:\下)

<bean id="taskExecutor"
class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">
<property name="corePoolSize" value="4" /> <!-- 并发线程数,想达到真正的并发效果,最好对应CPU的线程数及核心数 -->
<property name="maxPoolSize" value="1000" /> <!-- 最大线程池容量 -->
<property name="queueCapacity" value="2000" /> <!-- 超过最大线程池容量后,允许的线程队列数 -->
</bean>

这里我是设置4并发数，最大线程池容量1000

F:\>ab -n 10000 -c 1000 http://192.168.40.21:8080/cctv/test/excute

这句命令表示10000次请求，1000个并发数 ，用时：1.206ms

比正常配置 10000*1000-4*1000=9996000
