本文介绍了在学习阶段搭建的分布式项目，使用SSM（Spring、SpringMVC、Mybatis）作为基础，结合Dubbo进行服务治理，并利用Zookeeper作为注册中心。在项目构建过程中，解决了jar包冲突、Shiro缓存和Ehcache的冲突，详细描述了各个模块的配置，包括web.xml、dubbo配置、Shiro配置等。同时，强调了依赖的传递性和代码编写注意事项，如匹配XML路径、实体类的序列化以及Controller层引用服务的方法。
注：由于是学习阶段搭建的项目，命名和代码很多不规范
- 基本准备
创建maven的父项目
注意：父项目为maven project，直接创建一个简单工程
将ssm项目中的模块抽出分别创建maven的子项目
在父项目的基础上创建maven module
dao层：
entity层：
interface层(service层)：
创建为jar项目
serviceImpl层：
web层：
以上为war包的方式创建项目
注意：若项目报错，请手动在webapp下的WEB-INF下添加web.xml文件
-
配置文件
父项目引入jar包依赖
注意：
- dubbo的jar包与springframework存在冲突，jar包依赖导入时解决
- shiro的缓存技术和ehcache存在冲突，引入低版本的ehcache的依赖，在pom中已解决

dao层：
dao层与mybatis的整合，可以使用逆向工程进行创建，这里不使用逆向工程，自己编写mapper与xml
