java正则匹配json

有些时候如果json格式数据里如果value带有双引号,则这样的数据无法直接用json工具解析出来，需要手动去处理,下边的正则表达式匹配出带有双引号的value。

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 matcher = pattern.matcher(str);
while (matcher.find()){

if(matcher.group(1)!=null) {

System.out.println("key:" + matcher.group(1));

System.out.println("value:" + matcher.group(2));

}else{

System.out.println("key:" + matcher.group(3));

System.out.println("value:" + matcher.group(4));

}
}
