"\w" -> "\\w"in the source code will check the char '' .
change:
String aa = "{\"required\":true,\"regex\":"([\\\\w-]+\\\\.)+[\\\\w-]+(/[\\\\w-./?%&=]*)?\"}";LinkedHashMap ruleMap = JSON.parseObject(aa, LinkedHashMap.class);System.out.println(MapUtils.getString(ruleMap,"regex",""));
String aa = "{\"required\":true,\"regex\":"([\\\\w-]+\\\\.)+[\\\\w-]+(/[\\\\w-./?%&=]*)?\"}";
LinkedHashMap ruleMap = JSON.parseObject(aa, LinkedHashMap.class);
System.out.println(MapUtils.getString(ruleMap,"regex",""));
