Gson反序列化和序列化瞬态字段

Question

我有以下 Pojo Class 和一个字段瞬态：

public class User implements Serializable {

    public static final long serialVersionUID = 1L;
    public String name;
    transient public UserSession[] bookings;
}

我希望使用 Gson 库对瞬态文件进行序列化和反序列化，但不希望在文件上对文件进行序列化。我怎样才能实现它？

如前所述in the documentation：

By default, if you mark a field as transient, it will be excluded. As well, if a field is marked as "static" then by default it will be excluded. If you want to include some transient fields then you can do the following:

import java.lang.reflect.Modifier;

Gson gson = new GsonBuilder() .excludeFieldsWithModifiers(Modifier.STATIC) .create();

这将从 Gson 序列化中排除 static 个字段，但不排除 transient 和 volatile 个字段。
