Class EnumDeserializer

java.lang.Object

com.fasterxml.jackson.databind.JsonDeserializer<T>

com.fasterxml.jackson.databind.deser.std.StdDeserializer<T>

com.fasterxml.jackson.databind.deser.std.StdScalarDeserializer<Object>

com.fasterxml.jackson.databind.deser.std.EnumDeserializer

All Implemented Interfaces:

com.fasterxml.jackson.databind.deser.ContextualDeserializer, com.fasterxml.jackson.databind.deser.NullValueProvider, com.fasterxml.jackson.databind.deser.ValueInstantiator.Gettable, Serializable

@Deprecated
public class EnumDeserializer
extends com.fasterxml.jackson.databind.deser.std.StdScalarDeserializer<Object>
implements com.fasterxml.jackson.databind.deser.ContextualDeserializer

Deprecated.

枚举类反序列化程序类，可以从字符串和整数反序列化指定枚举类的实例。 官方提供的，支持（但不限于）以下接收方式： 1、字符串 如：sex: "M" 2、数字 如：sex: 1 // 数字需要和枚举类的顺序对应，超过会报错。 如Sex 有M、W、N ，则数字只能是 0、1、2 3、数组 还不清楚怎么使用...

我重写了后，增强了以下功能。 1、传递的枚举类型可以是对象. 如： sex: { "code": "M" }

本类跟jackson-databind包中的EnumDeserializer类同包名，利用类加载机制，会加载此类，不会加载到jackson-databind中的类 参考 BasicDeserializerFactory#1495 行代码
