系统架构

（1）开发环境要求

（2）项目技术架构简介

采用当前流行的前后端编程架构：

1：后端框架采用 Spring +SpringMVC+mybatis +Dubbo2 ：前端采用AdminLTE框架的前端解决方案（3）工程依赖关系预览

（3）maven父子项目的好处

parent 就是 project 子则是module

1、父子工程对于模块的分离程度更高了以前：项目不断变大和复杂化，改动与编译困难现在：简单，改动的也只是这一个模块而已，并不会影响其他的模块2、父子工程使代码更清晰，提高了重用以前：多个模块重复引入依赖现在：使用父子工程，则只需要在父工程中引入了，则子工程自动继承

创建父项目–parent工程

（1）file–>new–>Maven–>next–>finish

（2）添加依赖pom.xml

（3）clean–>install

在新建每个父工程子工程，都要给每个父子工程执行- clean install

（4）.gitignore

*.iml *.jar *.class target/ .idea/

创建子工程

（1）创建子工程，不需要使用模板

1、export_domain

执行clean与install

pom.xml添加<packaging>jar</packaging>

2、export_dao

执行clean与install

pom.xml添加<packaging>jar</packaging>

3、export_system_service

执行clean与install

pom.xml添加<packaging>jar</packaging>

4、export_web_manager

执行clean与install

pom.xml 删除其他标签（<name>export_web_manager</name>以下的都要删除） pom.xml添加<packaging>war</packaging>

5、export_parent

pom.xml添加<packaging>pom</packaging> 查看是否有modules

（2）注意

（1）一定要选中parent 为【export_parent】（2）每个模块创建完，第一次，要执行clean与install（3）最后一个web选一下，删除其他标签

（3）建包，先分层再分模块

（4）定义实体类

在domain中添加实体类

（5）完善依赖关系

通过dependencies完web依赖 service,service依赖dao,dao依赖domain

1、dao依赖domain

export_dao\pom.xml

<dependencies> <dependency> <artifactId>export_domain</artifactId> <groupId>com.smp</groupId> <version>1.0-SNAPSHOT</version> </dependency> </dependencies>

2、service依赖dao

export_system_service\pom.xml

<dependencies>   <dependency> <artifactId>export_dao</artifactId> <groupId>com.smp</groupId> <version>1.0-SNAPSHOT</version> </dependency> </dependencies>

3、web依赖service

export_web_manager\pom.xml

<dependencies> <dependency> <artifactId>export_system_service</artifactId> <groupId>com.smp</groupId> <version>1.0-SNAPSHOT</version> </dependency> </dependencies>
