CXF+Spring多线程访问异常

H~~~ 2010-02-24 11:52:06
我用CXF2.2.5和Spring2.5.5开发web service，我用80以内个线程访问这个web service没有问题，当线程数提高到100时，报以下异常：

我觉得有可能是我获取bean的方式占用了过多的资源导致的，我是用
new ClassPathXmlApplicationContext("beans-client.xml" ).getBean("beanName");
方式获得bean的，但是我没有想到好的解决办法。我把系统变量JAVA_OPTS设置为-Xms64m -Xmx1024m没有解决问题(我的内存是2G)。

多半是你程序自身有内存泄露问题吧。没代码也不好帮你看，只能自己用jprofile看看到底在哪儿有问题。


没有找到问题的根本原因，但是我用线程池来缓冲，解决了问题。还是很感谢你的！分数都给你~

                for (int i = 0; i < 180; i++) {

			new ThreadTest("线程"+i).start();

		}


180线程并行请求一次，像上面那样~

180线程并行什么概念。是不停的在请求，还是180线程每个线程只请求一次？

程序现在可以并行180个线程没有出现问题，由于该程序以后会承载很大的压力，到200线程的时候就会出现2楼的异常，请大家帮帮忙！

factory肯定只能创建一次的。你多次创建那是不对的。

public class BeanUtils {

public static BeanFactory factory = new ClassPathXmlApplicationContext("beans-client.xml");

public static Object getBean() {
factory.getBean("beanName")
}
}

如果在web容器中，应该还可以在web载入时装载，然后通过
WebApplicationContext wac =
WebApplicationContextUtils.getRequiredWebApplicationContext(getServletContext());
this.proxy = (Servlet)wac.getBean(targetBean);

只晓得是内存溢出，看样子是程序的问题，可惜看不懂，友情帮顶，坐等高人来解决

我做了以下修改：


static {

		context = new ClassPathXmlApplicationContext("beans-client.xml" );

		

	}

现在并发量提高了，但是有时会出现以下异常：
