在产生这个问题的时候,以为是代码某个类又改动了。但是对比了git,发现并没有改动,测试环境代码照跑,故又重新拉了一份重新部署,仍然报同样的错。解决过程中,试了以下网上各种方法,均无效果。 1、包重复、缺失;(都是跑了俩礼拜的项目了,突然少包什么的可能性不大) 2、jdk问题;(设置翻了一遍,发现都是8,也没有问题) 3、映射文件发生改变。(没有类的改动,也没有映射文件的改动,排除)   ...

java代码的在线运行,对其内存限制,时间检测等问题[ga]

基本需求类似[<em>java</em>在线代码编译运行],多个客户都可以各自通过web浏览器输入<em>java</em>代码, 然后点击执行<em>java</em>代码,输出结果。 我是通过(Class thisClass = Class.forName(className,true,ClassLoader.getSystemClassLoader()); 来实现的) 目前比较担心某个用户输入的<em>java</em>代码可能是个死循环(如:while(true){xxxx}), 或者高内存使用(如:大规模的向内存里添加字符串) 这样可能会由于一个用户的代码问题,致使整个jvm宕机。 因此,请问,一个用户在执行<em>java</em>代码时候,可有什么方法,对这段代码的内存的使用率, 或者程序的运行时间,进行限制或者检测? (如果超过一定内存使用量,或者一定运行时间,就终止运行) 有个在线运行的网站:http://ideone.com/ 这里就可以对时间进行检测,超过一分钟就终止。 请问这是怎样检测执行操作的? 整个思路不是很清楚,请<em>高手</em>帮忙解答下, 谢谢。
