JSON to Scala class with GSON - SerializedName annotation does not work

[Tim]

I have a simple Scala class:

import com.google.gson.annotations.SerializedName

extends Serializable { ... }

And I have this code:

val testJson = "{\"myTest\": \"my-test\"}"

val myTest = gson.fromJson(testJson, classOf[MyTest])

This works fine! The content of the variable of *myTest* is *my-test*.

In reality, my JSON looks like this:

val testJsonWithUnderscore = "{\"my_test\": \"my-test\"}"

val myTest = gson.fromJson(testJsonWithUnderscore, classOf[MyTest])

So, the variable name *myTest* does not match with the *my_test* of the
JSON string. So I included *@SerializedName("my_test")* but it does not
work. The var *myTest* is *null*.

The *@SerializedName("my_test")* does not work like expected. What is wrong
here?

Hi Tim -
I have exactly the same issue. Were you able to find a resolution?

thanks

You can just add it as var in body for example:

class MyTest(){
@SerializedName("my_test")
var myTest: String = null
}
