本文整理了Java中com.fasterxml.jackson.databind.ObjectMapper._serializerProvider()方法的一些代码示例，展示了ObjectMapper._serializerProvider()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ObjectMapper._serializerProvider()方法的具体详情如下：
包路径：com.fasterxml.jackson.databind.ObjectMapper
类名称：ObjectMapper
方法名：_serializerProvider

ObjectMapper._serializerProvider介绍

[英]Object that manages access to serializers used for serialization, including caching. It is configured with #_serializerFactory to allow for constructing custom serializers.

Note: while serializers are only exposed SerializerProvider, mappers and readers need to access additional API defined by DefaultSerializerProvider
