###1、需求
1、IntelliJ IDEA打开多个项目
2、每个同学开发一个项目,相互之前独立不影响
3、通过一个入口可以调用所有项目类、方法、属性,达到同时开发且检测代码
4、dependency只需要写一份,其余项目不用写,便可全部依赖
###2、注意事项(非常重要)
6个坑:
1、
项目中所有的groupId要一样
2、避免循环依赖,导致程序报错
3、
打包的服务器运行时候需要provided,本机调试的时候,需要注释
在一个maven项目中,如果存在编译需要而发布不需要的jar包,可以用scope标签,值设为provided
4、项目、module建好之后需要添加Scala的框架支持
5、在yhProject中,可以统一对所有的module进行清理、编译、打包
6、要运行依赖中的module,则必须要将module中的Jar包,打到maven中,需要使用install
下面,是我将所有module中的Jar打到Maven中的路径:
###3、建立Project和建立module
1、只需要建立一个项目,其他项目由module建立,所有module且放在项目中。
2、本文项目为yhproject,其余都为module,分别是:mainEntrance、yhutils、yhapp、yhweb、yhgame
项目建立步鄹:
Module建立步鄹:
项目、所有module、部分module代码展示:

###5、代码展示
mainEntrance

yhutils
package com.yh.bi /** * Created by yuhui on 2017/2/10. */ import java.time.LocalDate import org.apache.spark.sql.SQLContext import org.slf4j.LoggerFactory abstract class Executor extends Task with SQLContextAware { override def run(appkey: String, startDay: LocalDate, endDay: LocalDate)={} } trait SQLContextAware { implicit var ctx: SQLContext = _ } abstract class Task { protected val LOG = LoggerFactory.getLogger(this.getClass) def executor(appkey: String, startDay: LocalDate, endDay: LocalDate): Unit def run(appkey: String, startDay: LocalDate, endDay: LocalDate): Unit = { executor(appkey, startDay, endDay) } }
yhapp
package com.yh.bi /** * Created by yuhui on 2017/2/10. */ import java.time.LocalDate object UserAPP extends Executor{ override def executor(appkey: String, startDay: LocalDate, endDay: LocalDate): Unit = { println("++++我的UserAPP的执行过程++++") } }
yhweb
package com.yh.bi import java.time.LocalDate object UserWEB extends Executor{ override def executor(appkey: String, startDay: LocalDate, endDay: LocalDate): Unit = { println("++++我的UserWEB的执行过程++++") } }
yhgame
package com.yh.bi /** * Created by yuhui on 2017/2/10. */ import java.time.LocalDate object UserGame extends Executor{ override def executor(appkey: String, startDay: LocalDate, endDay: LocalDate): Unit = { println("++++我的UserGame的执行过程++++") } }

###7、运行结果展示
注意:我在mainEntrance执行DAG中的main文件,可以调用且执行了yhutils、yhapp、yhweb、yhgame中的代码
###8、如果建立Java 的module
