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

maven父项目下载完所有jar包之后进行更新

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

配置文件：

注意：若dubbo标签报错，请手动引入xsd

注意：这里在整合shiro的时候，由于要配置过滤器的原因，我将shiro整合在了web层。然后应该公共抽取还是整合在web层中这一点我还不会。

注意：这里在web的配置文件中我使用了context-param标签，即为上面提到的冲突问题

shiro的配置文件：

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:noNamespaceSchemaLocation="../config/ehcache.xsd">
	<diskStore path="F:\develop\ehcache" />

引入对应的依赖

dao层引入entity实体层

同理：

service层引入实体层

serviceImpl层引入dao层与service层

**注意：**引入的依赖之间具有传递性

web层引入service层

代码编写：

dao层：

注意：这里在匹配xml时候的路径要尤为注意，否则会找不到xml

userDao.xml:

entity层：

注意：由于在网络上传输所以要实现Serializable

BaseEntity:

serviceImpl层：

注意：@Service使用dubbo的注解，否则无法上传到注册中心

web层：

整合shiro：

自定义realm：
