advanced patterns When Handling JSON Arrays with Custom Deserialization in Java Using Gson
I'm dealing with I'm trying to configure I've tried everything I can think of but I tried several approaches but none seem to work... I'm working with an scenario with deserializing a JSON array into a custom Java object using Gson. I'm trying to parse a JSON response that contains an array of user objects, but I'm getting an unexpected `JsonParseException`. Here's the JSON structure I'm working with: ```json { "users": [ { "id": 1, "name": "Alice" }, { "id": 2, "name": "Bob" } ] } ``` I have the following Java classes defined: ```java public class User { private int id; private String name; // getters and setters } public class UserResponse { private List<User> users; // getters and setters } ``` When I try to deserialize the JSON using the following code: ```java Gson gson = new Gson(); UserResponse response = gson.fromJson(jsonString, UserResponse.class); ``` I encounter the behavior: ``` com.google.gson.JsonParseException: java.lang.IllegalStateException: Expected a BEGIN_ARRAY but was STRING at path $.users ``` It seems like Gson is expecting an array but is interpreting it as a string. I've verified that the JSON string is correctly formatted by printing it out before deserialization. I've searched through the documentation and found that Gson generally handles collections well, so Iām puzzled as to why it interprets the `users` key incorrectly. I've also tried using `JsonElement` and `JsonArray` to manually parse the elements, but that feels unnecessary for this straightforward case. Any insights or suggestions on how to resolve this scenario would be greatly appreciated. I'm currently using Gson version 2.8.8. My team is using Java for this CLI tool. Has anyone dealt with something similar? This is part of a larger service I'm building. Am I missing something obvious? I'm working with Java in a Docker container on Ubuntu 22.04. This is for a application running on Linux. Am I missing something obvious?
