Gson 基于版本过滤字段 @Since 和 @Until

实体

public class User {

    @Since(value = 3)//大于这个值正常导出
    public String name;
    @Until(value = 4) //小于这个值正常导出
    public int age;
    @SerializedName(value = "email_Address",alternate = {"email","Address"})
    public String emailAddress;

    private String phone;
    
    ......
}

执行

    public static void main(String[] args) throws IOException {

        User user = new User();
        user.setAge(100);
        user.setEmailAddress("山西省运城市");
        user.setName("gy");
        user.setPhone("1808888888");

        Gson gson = new GsonBuilder().setVersion(4).create();
        String result = gson.toJson(user);
        System.out.println("result==="+result);//{"name":"gy","email_Address":"山西省运城市","phone":"1808888888"}

        String str = "{\"name\":\"gy\",\"age\":100,\"email_Address\":\"山西省运城市\",\"phone\":\"1808888888\"}";
        User user1 = gson.fromJson(str,User.class);
        System.out.println("use=="+user1.getName());//Version 大于3 use==gy Version小于3 use==null

    }
