@DanielChapman gives a good explanation of serialVersionUID, but no solution. the solution is this: run the serialver program on all your old classes. put these serialVersionUID values in your current versions of the classes. as long as the current classes are serial compatible with the old versions, you should be fine. (note for future code: … Read more
@JsonProperty annotations in your code are all put on private fields within your data class and by default Jackson doesn’t scan private fields for annotations. You have to instruct it to do otherwise by putting @JsonAutoDetect annotation: @JsonAutoDetect(fieldVisibility = Visibility.ANY) data class CurrencyInfo( @JsonProperty(“currency_info”) var currencyInfo: CurrencyInfoItem? ) or alternatively you can move your annotations … Read more
I found a way to achieve what I wanted: List<Person> persons = given().when().get(“person/”).as(Person[].class); UPDATE: Using Rest-Assured 1.8.1, looks like cast to List is not supported anymore. You need to declare and object array like this: Person[] persons = given().when().get(“person/”).as(Person[].class);
This is the solution outlined by Manoj: If you want to suppress serialization of a specific property Foo, but still be able to deserialize it, you can add a method public bool ShouldSerializeFoo() that always returns false. Example: public class Circle2 { public double Diameter { get; set; } public double Radius { get { … Read more
This was asked a long time ago, and is the first google result when looking up the error, but the accepted answer has no code and might be confusing for a jackson beginner (me). I eventually found this answer that helped. So, as stated in accepted answer, Implementing and register a “key deserializer” is the … Read more
I’ve searched a lot and the best way I’ve found so far is on this article: Class to serialize package net.sghill.example; import net.sghill.example.UserDeserializer import net.sghill.example.UserSerializer import org.codehaus.jackson.map.annotate.JsonDeserialize; import org.codehaus.jackson.map.annotate.JsonSerialize; @JsonDeserialize(using = UserDeserializer.class) public class User { private ObjectId id; private String username; private String password; public User(ObjectId id, String username, String password) { this.id = … Read more
You have to specify the type of T at the time of deserialization. How would your List of posts get created if Gson didn’t know what Type to instantiate? It can’t stay T forever. So, you would provide the type T as a Class parameter. Now assuming, the type of posts was String you would … Read more
Well, if you just need a single extra property, one simple approach is to parse your JSON to a JObject, use ToObject() to populate your class from the JObject, and then use SelectToken() to pull in the extra property. So, assuming your class looked something like this: class Person { [JsonProperty(“name”)] public string Name { … Read more
When parsing from an object to JObject you can specify a JsonSerializer which instructs how to handle dates. JObject.FromObject(new { time = s }, new JsonSerializer { DateParseHandling = DateParseHandling.None }); Unfortunately Parse doesn’t have this option, although it would make sense to have it. Looking at the source for Parse we can see that … Read more
To be able to handle deserialization errors, use the following code: var a = JsonConvert.DeserializeObject<A>(“– JSON STRING –“, new JsonSerializerSettings { Error = HandleDeserializationError }); where HandleDeserializationError is the following method: public void HandleDeserializationError(object sender, ErrorEventArgs errorArgs) { var currentError = errorArgs.ErrorContext.Error.Message; errorArgs.ErrorContext.Handled = true; } The HandleDeserializationError will be called as many times as … Read more
