Gson.toJsonTree介绍

[英]This method serializes the specified object into its equivalent representation as a tree of JsonElements. This method should be used when the specified object is not a generic type. This method uses Class#getClass() to get the type for the specified object, but the getClass() loses the generic type information because of the Type Erasure feature of Java. Note that this method works fine if the any of the object fields are of generic type, just the object itself should not be of a generic type. If the object is of generic type, use #toJsonTree(Object,Type) instead.
[中]此方法将指定的对象序列化为JsonElements树的等效表示形式。当指定的对象不是泛型类型时，应使用此方法。此方法使用类#getClass（）获取指定对象的类型，但由于Java的类型擦除功能，getClass（）会丢失泛型类型信息。请注意，如果任何对象字段都是泛型类型，则此方法可以正常工作，只是对象本身不应是泛型类型。如果对象是泛型类型，请改用#toJsonTree（对象，类型）。
