java解析String字符串(json格式)
需要jar包：json-lib-2.4-jdk15.jar
一、
String str = "{\"name\":\"zhangsan\",\"password\":\"zhangsan123\",\"email\":\"10371443@qq.com\"}";
此时用JSONObject：
1 String str = "{\"name\":\"zhangsan\",\"password\":\"zhangsan123\",\"email\":\"10371443@qq.com\"}"; 2 JSONObject json = JSONObject.fromObject(str); 3 System.out.println(json.getString("name"));
二、
String jsonString = "[{\"name\":\"zhangsan\",\"password\":\"zhangsan123\",\"email\":\"10371443@qq.com\"}"
+ ",{\"name\":\"lisi\",\"password\":\"lisi123\",\"email\":\"1435123@qq.com\"}]";
此时用JSONArray:
1 String jsonString = "[{\"name\":\"zhangsan\",\"password\":\"zhangsan123\",\"email\":\"10371443@qq.com\"}" 2 + ",{\"name\":\"lisi\",\"password\":\"lisi123\",\"email\":\"1435123@qq.com\"}]"; 3 JSONArray jsonArray = JSONArray.fromObject(jsonString); 4 for(int i = 0 ;i < jsonArray.size() ; i++){ 5 System.out.println("name = "+jsonArray.getJSONObject(i).getString("name")); 6 System.out.println("password = "+jsonArray.getJSONObject(i).getString("password")); 7 System.out.println("email = "+jsonArray.getJSONObject(i).getString("email")); 8 }
两个的输出结果为：
zhangsan ========================================= name = zhangsan password = zhangsan123 email = 10371443@qq.com name = lisi password = lisi123 email = 1435123@qq.com
