Class IntValueEnumTypeHandler<T extends ByteEnum>

java.lang.Object

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

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

com.github.lynzabo.common.IntValueEnumTypeHandler<T>

All Implemented Interfaces:

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

public class IntValueEnumTypeHandler<T extends ByteEnum>
extends org.apache.ibatis.type.BaseTypeHandler<T>

MyBatis通用按值转换 枚举转换处理器
适合于所有实现于ByteEnum接口的枚举类
MyBatis自带枚举处理器EnumOrdinalTypeHandler是按照索引赋值，如处理MclusterStatus枚举，数据库的值为9，应对应枚举项STOPED， 但使用EnumOrdinalTypeHandler却对应的是DESTROYING，因为DESTROYING索引为9
