问题描述

检查URL在Java中是否有效的最佳方法是什么?

如果试图调用new URL(urlString)并捕获到MalformedURLException，但对于以http://开头的任何内容似乎都感到满意.

我不关心建立连接，只是有效性.有办法吗? Hibernate Validator中的注释?我应该使用正则表达式吗?

I'm not concerned about establishing a connection, just validity. Is there a method for this? An annotation in Hibernate Validator? Should I use a regex?
