JAVA替换replaceAll方法报错：Illegal group reference

 

Exception in thread "main" java.lang.IllegalArgumentException: Illegal group reference
at java.util.regex.Matcher.appendReplacement(Matcher.java:857)
at java.util.regex.Matcher.replaceAll(Matcher.java:955)
at java.lang.String.replaceAll(String.java:2223)

 

 

这个是因为要替换的值含有“$”符号，处理一下

value = java.util.regex.Matcher.quoteReplacement(value);

方法源码
