【IntelliJ IDEA学习之五】IntelliJ IDEA 搭建项目
版本：IntelliJIDEA2018.1.4
一、同一窗口展示多个应用（弊端：耗内存）
idea没有eclipse workspace的概念，如果想在同一窗口显示多个应用，可以按照如下方式来做：
1、新建空工程
File-->new-->Project...
2、新建Modules
CTRL+ALT+SHIFT+S：
比如新建一个静态页面模块：
新建一个纯Java应用：
左侧选择Java，右侧选择JDK，下面不要选择任何Frameworks
最后效果：
二、搭建java web工程
1、搭建
(1)新建Java Enterprise
(2)在WEB-INF下面新建两个Directory:classes和lib
2、配置web项目（CTRL+ALT+SHIFT+S）
(1)配置编译输出路径
(2)添加依赖jar包
编译之后：
(3)配置打包方式Artifacts
编译之后：
(4)Tomcat配置
Tomcat 集成原理：
为项目配置了 tomcat 后，idea 会拷贝一份配置到系统目录中，如下
(1)conf存放配置：
Tomcat 之所以可以 root 启动和热部署，原因在如下:
(2)logs目录是各项日志：
(3)work目录存放class和页面文件：
三、搭建maven工程
1、搭建简单java工程，使用模板：maven-archetype-quickstart
配置配置 groupId 和 ArtifactId：
配置 maven 构建工具信息：
配置module信息：
Finish，完成。稍等片刻，选择右下角，enable auto import：
最终效果：
2、搭建maven web工程
使用模板：maven-archetype-webapp
使用模板创建的目录没有java和resources目录，执行创建然后，修改目录属性
最终效果：
3、不使用maven模板创建工程：
maven类型工程配置tomcat与上面普通Java web应用相同。
遇到的问题：
tomcat启动后，jsp未编译。
原因：项目Artifacts配置有问题
参考：正场项目的配置：
另附上正常启动tomcat日志,和eclipse不太一样，注意几个关键点：
