以下是部分代码:
File clientj = new File("client.jar");
URLClassLoader cl = new URLClassLoader(new URL[]{clientj.toURI().toURL()
});
Class<?> clientc = cl.loadClass("client");
Object clientobj = clientc.newInstance(); //报错部分显示是在创建实例中出错
求大大帮忙看看!
------解决方案--------------------
构造函数不断自己初始化，形成了循环，不断的new，然后堆栈溢出了，建议换其他写法，这个不安全
