maven+tomcat7 plugin configuration

I have nothing to do today. I looked at the relevant materials of maven+tomcat and found that maven has made a simplified version of tomcat. All tomcat fans have good news.

<plugin>
	<groupId>org.apache.tomcat.maven</groupId>
	<artifactId>tomcat7-maven-plugin</artifactId>
	<version>2.0-beta-1</version>
	<configuration>
	<uriEncoding>utf-8</uriEncoding>
	<port>80</port>
	<path>/</path>
	</configuration>
</plugin>

 Put the above code into pom.xml, run tomcat:run and it's OK, isn't it very simple, no need to download tomcat, no need to configure tomcat.

Note: If there are servlet-api.jar, jsp-api.jar, el-api.jar in pom.xml, these three packages should be removed. tomcat comes with these 3 packages
