Case insensitive JSON to POJO mapping without changing the POJO

Question

Does anyone know how com.fasterxml.jackson.databind.ObjectMapper is able to map JSON properties to POJO properties case insensitive?

JSON-String:

Answer 1

An alternative solution is to specify JSON field names case-sensitive:

public Movie(){
    //Jackson deserialize
}
@JsonProperty("Title")
public String getTitle() {
    return title;
}

@JsonProperty("Year")
public String getYear() {
    return year;
}
@JsonProperty("imdbID")
public String getImdbID() {
    return imdbID;
}
