背景
最近在对公司开发框架进行优化，框架内涉及到多处入库的日志记录，例如登录日志/操作日志/访问日志/业务执行日志，集成在业务代码中耦合度较高且占用业务操作执行时间，所以准备集成相关消息队列进行代码解耦
方案规划
现有的成熟消息队列组件非常多，例如RabbitMQ，ActiveMQ，Kafka等，考虑到业务并发量不高且框架已经应用于多个项目平稳运行，准备提供基于Redis的消息队列和集成ActiveMQ两种方案，Redis消息队列的好处是无需额外安装部署存量项目可平稳过度但消息无法持久化可能丢失，ActiveMQ解决方案成熟可以保证消息持久化但是需要实施人员额外掌握操作部署
统一设计
增加自定义配置指定消息队列方式

system: #消息队列方式 redis/activemq messageChannel: redis |
定义消息传输统一模型

定义标准消息处理接口

public interface IMessageReceiver { void handleMessage(Object bodyObject, HashMap extraParam); } |
定义统一对外发送消息工具类
