list转json Gson中list转json

List<String> list = new ArrayList<String>();

list.add("abc");

list.add("123");

JSONArray jsonArray = JSONArray.fromObject(list);

System.out.println(jsonArray.toString());

Gson gson = new Gson();

List<Person> persons = new ArrayList<Person>();

for (int i = 0; i < 10; i++) {

     Person p = new Person();

     p.setName("name" + i);

     p.setAge(i * 5);

     persons.add(p);

}

String str = gson.toJson(persons);
