小编给大家分享一下IntelliJ IDEA如何打开多个Maven的module且相互调用,相信大部分人都还不怎么了解,因此分享这篇文章给大家参考一下,希望大家阅读完这篇文章后大有收获,下面让我们一起去了解一下吧!
###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、<groupId>com.yh.bi</groupId>
项目中所有的groupId要一样
2、避免循环依赖,导致程序报错
3、<scope>provided</scope>
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:
###4、项目之前的依赖关系
###5、代码展示
mainEntrance

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++++") } }
