Jackson overcoming underscores in favor of camel-case
jackson, java
Solution
You should use the `@JsonProperty` on the field you want to change the default name mapping.
class User{
@JsonProperty("first_name")
protected String firstName;
protected String getFirstName(){return firstName;}
}

Problem
I retrieve a JSON string from internet; like most JSON I've seen it includes long keys that are separated by underscores. Essentially, my goal is to deserialize JSON into java-objects, but I don't use underscores in java-code. For instance, I might have a `User` class with `firstName` field in camel-case, simultaneously I need somehow to tell Jackson to map `first_name` key from JSON to `firstName` class field. Is it possible? ``` class User{ protected String firstName; protected String getFirstName(){return firstName;} } ```
