What is GSON in Java with example?

GSON is Google’s JSON parser and generator for Java. Google developed GSON for internal use but open sourced it later. In this GSON tutorial I will take you through how to use GSON to parse JSON into Java objects, and serialize Java objects into JSON. GSON contains multiple APIs which you can use to work with JSON.

Should I use Gson?

GSON has been successfully used in several android apps that are in Google Play today. The benefit you get with GSON is that object mapping can save the time spent writing code.

Do Jackson annotations work with Gson?

For example, Jackson’s ObjectMapper (its internals) reads the type you provide, introspects it to find any meaningful annotations, and uses them to serialize/deserialize. @SerializedName isn’t meaningful to Jackson, so it ignores it. Similarly, @JsonProperty isn’t meaningful to Gson, so it ignores it.

What is a GSON file?

Does GSON use reflection?

Usage. Gson uses reflection, so it does not require classes being serialized or de-serialized to be modified. By default, it just needs the class to have defined default no-args constructor (which can be worked around, see Features).

Is Gson safe?

Gson is great as well; it’s a de-facto standard for JSON parsing on Android for a good reason. But! Data classes parsed via Gson guarantee neither null-safety nor even default values.
