disconf-client

简洁而强大的spring配置工具

• 代码量大约只有原作者的1/10, 没有繁琐的二次扫描啥的.
• 解决了几个bug, 比如debug=true时断线就不重连,莫名其名的断线等.
• 支持json和 * 通配符配置
• 配置更简洁, 业务代码无侵入, 只需要关注原生spring @Value注解
• 配置变更后自动修改@Value注解的字段,和自动调用@Value注解的setter方法
• 即使不使用disconf也能使用框架的接口主动修改配置

# settings.properties
app.title=someGame
app.tags=["play","war"]
app.user.hobby.lilei=fishing
app.user.hobby.HanMeimei=reading
