傑克遜克服下劃線支持駝峯式 - Jackson overcoming underscores in favor of camel-case

問題：

I retrieve a JSON string from internet;我從互聯網上檢索了一個 JSON 字符串； like most JSON I've seen it includes long keys that are separated by underscores.像我見過的大多數 JSON 一樣，它包含由下劃線分隔的長鍵。 Essentially, my goal is to deserialize JSON into java-objects, but I don't use underscores in java-code.本質上，我的目標是將 JSON 反序列化爲 java 對象，但我不在 java 代碼中使用下劃線。

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.例如，我可能有一個帶有駝峯式firstName字段的User類，同時我需要以某種方式告訴 Jackson 將first_name鍵從 JSON 映射到firstName類字段。 Is it possible?是否有可能？

class User{
    protected String firstName;
    protected String getFirstName(){return firstName;}
}
