代码样例：

// 输出结果为{"version": 4,"addr": "192.160.1.11"}private static void test1(){String s = "{\"internal_1\": [{\"version\": 4,\"addr\": \"192.160.1.11\"}]}";String regex = ".+?\\[(.+?)\\].+?";Pattern pattern = Pattern.compile(regex);Matcher matcher = pattern.matcher(s);if (matcher.matches()) {String group = matcher.group(1);System.out.println(group);}else {System.out.println("no matches!!");}}// 输出结果为{"Done":1,"ReturnType":1,"Msg":"HELLO,上海"}private static void test2(){String s="TestJsonResponse{TestJsonResult={\"Done\":1,\"ReturnType\":1,\"Msg\":\"HELLO,上海\"};}";String regex = ".+?\\=(.+?)\\;.+?";Pattern pattern = Pattern.compile(regex);Matcher matcher = pattern.matcher(s);if (matcher.matches()) {String group = matcher.group(1);System.out.println(group);}else {System.out.println("no matches!!");}}//结果为HELLO,上海private static void test3() {  /*JSONObject jsonObject = new JSONObject();   try {jsonObject.put("a", 1);jsonObject.put("b", 1.1);   jsonObject.put("c", 1L);   jsonObject.put("d", "test");   jsonObject.put("e", true);   } catch (JSONException e) {// TODO Auto-generated catch blocke.printStackTrace();}   System.out.println(jsonObject); // 输出{"d":"test","e":true,"b":1.1,"c":1,"a":1}try {System.out.println(jsonObject.getString("d"));// 输出test} catch (JSONException e) {// TODO Auto-generated catch blocke.printStackTrace();} */String s="{\"Done\":1,\"ReturnType\":1,\"Msg\":\"HELLO,上海\"}";try {JSONObject jsonObject2 = new JSONObject(s); System.out.println(jsonObject2.getString("Msg")); // 输出HELLO,上海} catch (JSONException e) {// TODO Auto-generated catch blocke.printStackTrace();} }
