idea如何创建maven项目（IDEA构建maven项目）

1.右侧maven目录中的site:run,双击之后可以运行项目。

2.IDEA可以创建多个module，打包类型分为jar或者war。

本项目采用maven分模块开发方式，即对整个项目拆分为几个maven工程，每个maven工程存放特定的一类代码，具体如下：各模块职责定位：health_parent：父工程，打包方式为pom，统一锁定依赖的版本，同时聚合其他子模块便于统一执行maven命令health_common：通用模块，打包方式为jar，存放项目中使用到的一些工具类、实体类、返回结果和常量类health_interface：打包方式为jar，存放服务接口health_service_provider：Dubbo服务模块，打包方式为war，存放服务实现类、Dao接口、Mapper映射文件等，作为服务提供方，需要部署到tomcat运行health_backend：传智健康管理后台，打包方式为war，作为Dubbo服务消费方，存放Controller、HTML页面、js、css、spring配置文件等，需要部署到tomcat运行health_mobile：移动端前台，打包方式为war，作为Dubbo服务消费方，存放Controller、HTML页面、js、css、spring配置文件等，需要部署到tomcat运行。

3.module可以指定parent,并继承pom中的依赖。

4.POM文件定义。

parent模块中，可以定义版本号如下——

<!-- 集中定义依赖版本号 --> <properties> <junit.version>4.12</junit.version> <spring.version>5.0.5.RELEASE</spring.version> <pagehelper.version>4.1.4</pagehelper.version> <servlet-api.version>2.5</servlet-api.version> <dubbo.version>2.6.0</dubbo.version> <zookeeper.version>3.4.7</zookeeper.version> <zkclient.version>0.1</zkclient.version> <mybatis.version>3.4.5</mybatis.version> <mybatis.spring.version>1.3.1</mybatis.spring.version> <mybatis.paginator.version>1.2.15</mybatis.paginator.version> <mysql.version>5.1.32</mysql.version> <druid.version>1.0.9</druid.version> <commons-fileupload.version>1.3.1</commons-fileupload.version> <spring.security.version>5.0.5.RELEASE</spring.security.version> <poi.version>3.14</poi.version> <jedis.version>2.9.0</jedis.version> <quartz.version>2.2.1</quartz.version> </properties>

则子模块中就不需要定义版本号。

parent模块中dependencies如下——

<!-- 依赖管理标签 必须加 --> <dependencyManagement> <dependencies> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId>
