Eclipse创建Maven Java8 Web项目，并直接部署Tomcat

（1）先将Dynamic Web Module的勾去掉
（2）将Java版本改为1.8，点击Apply
（3）再勾选Dynamic Web Module，点击Apply
（4）单击下方出现的Further configuration available，进行设置

单击右侧Runtimes，选择本机安装的Tomcat

单击Apply and Close按钮，保存设置

报错是因为找不到servelt-api，编辑pom.xml

注意：这个并不是默认的maven项目的标准结构，我们需要改造一下

右键单击项目，选择New–>Source Folder

Folder name处输入src/main/java，单击Finish按钮
