将json字符串转化成JavaBean对象
Person person = new Person("1","fastjson",1);
//这里将javabean转化成json字符串
String jsonString = JSON.toJSONString(person);
//这里将json字符串转化成javabean对象,
person =JSON.parSEObject(jsonString,Person.class);

将json字符串转化成List<JavaBean>对象
Person person1 = new Person("1","fastjson1",1);
Person person2 = new Person("2","fastjson2",2);
List<Person> persons = new ArrayList<Person>();
persons.add(person1);
persons.add(person2);
String jsonString = JSON.toJSONString(persons);
System.out.println("json字符串:"+jsonString);
//解析json字符串
List<Person> persons2 = JSON.parseArray(jsonString,Person.class);
-
将json字符串转化成List<String>对象
List<String> list = new ArrayList<String>();
list.add("fastjson1");
list.add("fastjson2");
list.add("fastjson3");
String jsonString = JSON.toJSONString(list);
System.out.println("json字符串:"+jsonString);
//解析json字符串
List<String> list2 = JSON.parSEObject(jsonString,new TypeReference<List<String>>(){});
-
将json字符串转化成List<Map<String,Object>>对象
Map<String,Object> map = new HashMap<String,Object>();
map.put("key1","value1");
map.put("key2","value2");
Map<String,Object> map2 = new HashMap<String,Object>();
map2.put("key1",1);
map2.put("key2",2);
List<Map<String,Object>> list = new ArrayList<Map<String,Object>>();
list.add(map);
list.add(map2);
String jsonString = JSON.toJSONString(list);
System.out.println("json字符串:"+jsonString);
//解析json字符串
List<Map<String,Object>> list2 = JSON.parSEObject(jsonString,new TypeReference<List<Map<String,Object>>>(){});
