目录结构：
发现我们的源码包和资源包都没有配置，只有一个放置页面资源的webapp目录
我们可以把webapp拖动放到我们想存放的位置：
自己手动配置Resource和Java目录
在对main目录进行右键创建包的时候，IDEA会自动建议创建Maven项目的目录结构
JSP首页甚至没有JSP指令标签。。。
<html> <body> <h2>Hello World!</h2> </body> </html>
可以把POM配置这些都更新：
<properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.13</version> <scope>test</scope> </dependency> </dependencies>
也就是说这个骨架最初并不是给IDEA创建的
而是给Eclipse使用的。。。
接下来是配置Tomcat
点加号找到TomcatServer选择本地，千万别下面的EE Server
IDEA会提示你还没有配置Tomcat，直接Fix就好了
选下面这个explored的
自行更换工程资源路径：
重要的热部署选上：
启动项目发现404，结果之前好好的webapp目录IDEA不识别了
因为默认的配置路径IDEA找不到了，需要我们自己改上去：
把之前的index.jsp删除，重新配置一个
