特殊字符导致用正则表达式进行字符串替换失败，Java replaceAll()方法报错Illegal group reference

 

 

String str = "给商品||?>\\n阳澄湖大闸蟹!@#$%^&*()_+-=?:\",.]\\|~.,\/??\\\\|\\br点赞"

1 String tradeDescription = "||?>\\n阳澄湖大闸蟹!@#$%^";
2 String description = "给商品 #goodsName# 点赞";
3 String result = description.replaceAll("#goodsName#", Matcher.quoteReplacement(CommonUtil.toString(tradeDescription)));
