Jackson Serialize Field to Different Name

I have this JSON to deserialize: I want to serialize it to 2 different formats: [A] [B] I’m able to serialize it to 1 format: [A] only or [B] only.

I have this REST response: And this POJO: I’m using Spring RestTemplate with MappingJackson2HttpMessageConverter. With response above, prevValue is deserialized as a String like 1.0104401E7, in scientific notation. I want it to be deserialized without scientific notation.

Jackson Not Overriding Getter with @JsonProperty

If I serialize the class below with ObjectMapper and jackson I get As you can see the JsonProperty annotation has no effect Putting @JsonProperty on the String itself doesn’t work either.

Out of the box Jackson marshalls int to a number. In this case I want favoriteNumber to be

Serialization – How to secure a serialized JAVA object?

How can I secure the serialized object if I send the serialized object over the network? I doubt that hackers may interrupt/hack my data. can anyone tell in detail about how to implement this? Answer This presentation give ideas on how effectively attackers can tamper a Java serialized stream: https://www.owasp.org/images/e/eb/OWASP_IL_2008_Shai_Chen_PT_to_Java_Client_Server_Apps.ppt There is also the risk of injecting unsuspected behavior and

Jackson JSON do not wrap attributes of nested object

I’ve got following classes: When I serialize Container class using Jackson I get But I need the result to be: Is it possible (without adding Container.getDataId() method)? If so, how to do it? update I’ve tried to create custom JsonSerializer<Data> but the result was same as before I’ve also tried to add @JsonSerialize annotation above Data class, then above getter
