Class EnumValueAnnotationTypeHandler<E extends Enum<E>>

java.lang.Object

org.apache.ibatis.type.TypeReference<T>

org.apache.ibatis.type.BaseTypeHandler<E>

app.myoss.cloud.mybatis.type.EnumValueAnnotationTypeHandler<E>

Type Parameters:

E - 范型

All Implemented Interfaces:

org.apache.ibatis.type.TypeHandler<E>

public class EnumValueAnnotationTypeHandler<E extends Enum<E>>
extends org.apache.ibatis.type.BaseTypeHandler<E>

如果枚举字段使用了 EnumValueMappedType 注解，用于映射 "数据库中字段的值" 和 "java枚举" 的关系。
