Lottery学习记录

进度

1. 环境、配置、规范
2. 搭建(DDD + RPC)架构
3. 跑通广播模式RPC过程调用
4. 抽奖活动策略库表设计
5. 抽奖策略领域模块开发

遇到的问题

1. （第三节）跑通RPC调用例子时失败，经过仔细比对+研究issue发现 是dubbo的服务端注解service是spring的，改为dubbo的service注解就可以了
   
2. 用一台新电脑重新跑rpc启动服务端时，报bean注入失败与空指针，发现只有用alibaba那个注解才能启动成功，而原来的使用的apache的dubbo注解可以正常启动.
   经过一番研究后发现是JDK的锅。。。项目默认JDK用的是openJDK19 原来使用的是1.8的JDK.
   JDK19必须要使用alibaba那个dubbo注解才能跑起来
   1.8的对应apache的dubbo注解服务才能起来
