求一个正则表达式的解

我后台有这么一个字符串 [{"types":"收入","id":6},{"totalmoney":123,"id":7},{"types":"支出","id":8}]
我想通过正则表达式来分别得出“{}”内的一个对象
如String s="{'types':'收入'，'id':6}";这种形式，请问怎么弄，谢谢

[code="java"] public static void main(String[] args) {
String source = "[{\"types\":\"收入\",\"id\":6},{\"totalmoney\":123,\"id\":7},{\"types\":\"支出\",\"id\":8}]";

    String regex = "(\\{.*?\\})";

    Pattern  pattern = Pattern.compile(regex);

    Matcher matcher = pattern.matcher(source);

    while(matcher.find()){
        System.out.println(matcher.group(1));
    }
}[/code]
