类名称：ObjectMapper
方法名：getSerializerProvider

ObjectMapper.getSerializerProvider介绍

[英]Accessor for the "blueprint" (or, factory) instance, from which instances are created by calling DefaultSerializerProvider#createInstance. Note that returned instance cannot be directly used as it is not properly configured: to get a properly configured instance to call, use #getSerializerProviderInstance() instead.
[中]“blueprint”（或工厂）实例的访问器，通过调用DefaultSerializerProvider#createInstance从中创建实例。请注意，返回的实例不能直接使用，因为它没有正确配置：要获得要调用的正确配置的实例，请改用#getSerializerProviderInstance（）。
