如何用一种方法在Java中转义一组特殊字符? [英] how can i escape a group of special characters in java in one method?

问题描述

我使用lucene搜索，但是lucene有很多特殊字符可以逃脱，例如:

i use lucene search but lucene has a bunch of special characters to escape like:

- && || ! ( ) { } [ ] ^ " ~ * ? : \

由于这些字符太多，我在转义这些字符时遇到了问题，如果我使用String.replaceAll()方法，我最终将不得不花很长的一段代码来转义这些字符.最好的方法是什么?谢谢！

i am having problem escaping these characters because they are too many and if i use the String.replaceAll() method, i'll just end up having a really long line of code just for escaping the characters. what is the best way to do? thanks!

推荐答案

还有一种名为

There is also a method called QueryParser#escape, which may be useful:

返回一个字符串，其中QueryParser期望将其转义的那些字符由前面的\进行转义.

Returns a String where those characters that QueryParser expects to be escaped are escaped by a preceding \.
