Class MinIdShortCodeServiceImpl

java.lang.Object

icu.easyj.core.util.shortcode.impls.MinIdShortCodeServiceImpl

All Implemented Interfaces:

IShortCodeService

@LoadLevel(name="min-id",
           order=50)
public class MinIdShortCodeServiceImpl
extends Object
implements IShortCodeService

long型ID 与 短字符串 互相转换服务

该实现的目的是为了缩短短字符的长度。
按照default的实现，id值越小，生成的短字符串的长度就越短。
可以适当的缩短长度，在短链接码的应用中，缩短几个长度也能减少很多的短信成本。
