fastJson简单实用

public class FastJsonText {
@Test
public void text(){
User user1 = new User();
user1.setName("健康");
user1.setAge(18);
user1.setId(1);
user1.setBirthday(new Date());

User user2 = new User();
user2.setName("萌萌");
user2.setAge(19);
user2.setId(2);
user2.setBirthday(new Date());
List<User> list = new ArrayList<User>();
list.add(user1);
list.add(user2);
//过滤属性在json是否生成
SerializeFilter filter = new PropertyFilter() {
@Override
public boolean apply(Object arg0, String arg1, Object arg2) {
/*System.out.println(arg0);//要转化成json的对象
System.out.println(arg1);//属性名称
System.out.println(arg2);//属性值
*/ if("id".equals(arg1)){
return false;//代表不生成json
}
return true;
}
};
//转换成json
//String json =JSONObject.toJSONString(user1);
String json = JSONArray.toJSONString(list, filter);
System.out.println(json);
}
}

//补充:注解Date类型.

@JSONField(format="yyyy-MM-dd")
private Date birthday;
