--------------------

public static void main(String[] args) { String jsonString = "{\"page_size\":\"12321321\",\"page_size\":\"123\",\"page_index\":0,\"page_count\":0,\"has_next\":false,\"datas\":null,\"code\":0,\"issuccess\":true,\"msg\":null}"; String regex = "\"page_size\":\"(.*?)\\\"";//使用非贪婪模式 Matcher matcher = Pattern.compile(regex).matcher(jsonString); while (matcher.find()) { String ret = matcher.group(1); System.out.println("key:" + matcher.group(1)); } String str = "{\"keyword\":\"xin \"hua\",\"type\":\"news\",\"countryName\":\"not中国\"," + "\"pageNo\":1,\"pageSize\":10,\"beginDate\":\"\"\"2018-05-01 00:00:00\"\"\"," + "\"endDate\":\"2018-05-09 23:59:59\"}"; Pattern pattern = Pattern.compile("\"([a-zA-z0-9]{0,})\":\"{1}([a-zA-z0-9\\-\\s\\:\\u4e00-\\u9fa5\"]{0,})\"{1}[\\,\\}]{1}|" + "\"([a-zA-z0-9]{0,})\":([a-zA-z0-9\\-\\s\\:\\u4e00-\\u9fa5\"]{0,})[\\,\\}]{1}"); Matcher matcher1 = pattern.matcher(str); while (matcher1.find()){ if(matcher1.group(1)!=null) { //System.out.println("key:" + matcher1.group(1)); System.out.println("value:" + matcher1.group(2)); }else{ // System.out.println("key:" + matcher1.group(3)); System.out.println("value:" + matcher1.group(4)); } } }

返回结果

> key:12321321  
> key:123  
> value:xin “hua  
> value:news  
> value:not中国  
> value:1  
> value:10  
> value:”“2018-05-01 00:00:00"”  
> value:2018-05-09 23:59:59
