转换后的对象Object是一个MorphDynaBean的动态JavaBean,通过PropertyUtils可以获得指定的属性的值。
运行后结果如下:
==============JSON Object String >>> Java MorphDynaBean =============
chian
email@123.com
tom
chian
email@123.com
tom
3、 将json字符串转成Java的Array数组
private String json = "{\"address\":\"chian\",\"birthday\":{\"birthday\":\"2010-11-22\"},"+
"\"email\":\"email@123.com\",\"id\":22,\"name\":\"tom\"}";
@Test
public void readJSON2Array() {
try {
fail("==============JSON Arry String >>> Java Array ==================");
json = "[" + json + "]";
jsonArray = JSONArray.fromObject(json);
fail("#%%%" + jsonArray.get(0).toString());
Object[] os = jsonArray.toArray();
System.out.println(os.length);
fail(JSONArray.fromObject(json).join(""));
fail(os[0].toString());
Student[] stus = (Student[]) JSONArray.toArray(jsonArray, Student.class);
System.out.println(stus.length);
System.out.println(stus[0]);
} catch (Exception e) {
e.printStackTrace();
}
}
"\"email\":\"email@123.com\",\"id\":22,\"name\":\"tom\"}";
@Test
public void readJSON2Array() {
try {
fail("==============JSON Arry String >>> Java Array ==================");
json = "[" + json + "]";
jsonArray = JSONArray.fromObject(json);
fail("#%%%" + jsonArray.get(0).toString());
Object[] os = jsonArray.toArray();
System.out.println(os.length);
fail(JSONArray.fromObject(json).join(""));
fail(os[0].toString());
Student[] stus = (Student[]) JSONArray.toArray(jsonArray, Student.class);
System.out.println(stus.length);
System.out.println(stus[0]);
} catch (Exception e) {
e.printStackTrace();
}
}
运行的结果如下:
==============JSON Arry String >>> Java Array ==================
#%%%{"address":"chian","birthday":{"birthday":"2010-11-22"},"email":"email@123.com","id":22,"name":"tom"}

{"address":"chian","birthday":{"birthday":"2010-11-22"},"email":"email@123.com","id":22,"name":"tom"}

tom#22#chian#2010-11-22#email@123.com
#%%%{"address":"chian","birthday":{"birthday":"2010-11-22"},"email":"email@123.com","id":22,"name":"tom"}

tom#22#chian#2010-11-22#email@123.com
4、 将JSON字符串转成Java的List集合
private String json = "{\"address\":\"chian\",\"birthday\":{\"birthday\":\"2010-11-22\"},"+
"\"email\":\"email@123.com\",\"id\":22,\"name\":\"tom\"}";
@Test
public void readJSON2List() {
try {
fail("==============JSON Arry String >>> Java List ==================");
json = "[" + json + "]";
jsonArray = JSONArray.fromObject(json);
List<Student> list = JSONArray.toList(jsonArray, Student.class);
System.out.println(list.size());
System.out.println(list.get(0));
list = JSONArray.toList(jsonArray);
System.out.println(list.size());
System.out.println(list.get(0));//MorphDynaBean
} catch (Exception e) {
e.printStackTrace();
}
}
"\"email\":\"email@123.com\",\"id\":22,\"name\":\"tom\"}";
@Test
public void readJSON2List() {
try {
fail("==============JSON Arry String >>> Java List ==================");
json = "[" + json + "]";
jsonArray = JSONArray.fromObject(json);
List<Student> list = JSONArray.toList(jsonArray, Student.class);
System.out.println(list.size());
System.out.println(list.get(0));
list = JSONArray.toList(jsonArray);
System.out.println(list.size());
System.out.println(list.get(0));//MorphDynaBean
} catch (Exception e) {
e.printStackTrace();
}
}
运行后结果如下:
==============JSON Arry String >>> Java List ==================
