使用json工具類很難直接處理，這個時候可以利用字符串的方式：

private static List<String> getContentFromParenthese(String content) {ArrayList<String> contents = new ArrayList<String>();int m = 0, n = 0;int count = 0;for (int i = 0; i < content.length(); i++) {if (content.charAt(i) == '{') {if (count == 0) {m = i;}count++;}if (content.charAt(i) == '}') {count--;if (count == 0) {n = i;contents.add(content.substring(m, n + 1));}}}return contents;}

或者使用數組的方式：

private static List<String> getContentByArray(String content) {ArrayList<String> contents = new ArrayList<String>();List<Character> segment=new ArrayList<Character>();int count = 0; for(int i=0;i<content.length();i++){ System.out.println(content.charAt(i));if (content.charAt(i) == '{') { count++;}if (content.charAt(i) == '}') { count--;}if(count>0){segment.add(content.charAt(i));}if(count==0&&segment.size()>0){StringBuilder str = new StringBuilder();for (Character character : segment) {// 對ArrayList進行遍歷，將字符放入StringBuilder中 str.append(character);}contents.add(str.toString());segment=new ArrayList<Character>();}}return contents;}
