Gson Type Adapter vs. Custom Deseralizer

由 旧时模样 提交于 2020-01-10 09:55:11
问题 The example below shows a class (Club) that contains a collection of an abstract class (Member). I'm confused as to whether I need a TypeAdapter or JsonDeserializer to make the Deserialization work correctly. Serialization works just fine without any help, but Deserialization is throwing exceptions. To illustrate I've built the following "clone" test. If anyone could show a working example I would be very grateful. First Club Class package gson.test; import java.util.ArrayList; import com

问题 I have a very straight forward issue here. I need to take JSON coming from the API and convert it to objects I created for them.

Gson: JsonSyntaxException on date

由 若如初见. 提交于 2020-01-09 10:39:07
问题 I am trying to use Gson to deserialize a json array, but am currently getting a JsonSyntaxException. The json string was created by a .NET MVC3 web service using JsonResult (meaning, I am not manually creating the json, it is being created by a library which I know to work on several other platforms). This is the json: [{"PostID":1,"StudentID":39,"StudentName":"Joe Blow", "Text":"Test message.","CreateDate":"\/Date(1350178408267)\/", "ModDate":"\/Date(1350178408267)\/","CommentCount":0}] This

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Gson是Google提供的方便在json数据和Java对象之间转化的类库。 Gson 这是使用Gson的主要类，使用它时一般先创建一个Gson实例，然后调用toJson(Object)或者from(String,Class)方法进行转换。 package com.example.gson; import com.google.gson.annotations.Expose; import com.google.gson.annotations.SerializedName; import java.util.Date; /** * Student 实体类 * Created by liu on 13-11-25. */ public class Student { int age; String name; @Expose(serialize = true,deserialize = false) @SerializedName("bir") Date birthday; public Student(int age, String name, Date birthday) { this.age = age; this.name = name; this.birthday = birthday; }
