本节操作完成了maven下web工程的创建，并依赖tomcat插件完成启动
1、环境约束
- win10 64为操作系统
- idea2018.1.5
- maven-3.0.5
- jdk-8u162-windows-x64
2、前提约束
3、修改pom.xml
<!--在properties中申明版本的信息，在dependencies当中引用这些版本信息。如此使用，一旦版本有所改变，则直接修改properties中的信息即可-->

<artifactId>tomcat7-maven-plugin</artifactId>
<configuration>
<path>/</path>

</plugins>
</build>
4、启动tomcat插件
（1）按下图进行操作：
启动tomcat插件
（2）打开浏览器，输入http://localhost:8088，回车，出现如下图所示：
打开浏览器测试
至此，我们完成了在idea中创建一个web项目，并且配置了spring、springmvc、mybatis框架所有要的jar包依赖。
