在项目中，我们通过maven的插件，将项目达成war包，然后通过jenkins，自动化部署项目。
核心的maven配置文件，下面这一段pom.xml的配置文件。
将项目打包成ROOT.war
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<warName>ROOT</warName>
<archiveClasses>true</archiveClasses>
</configuration>
</plugin>配置pom.xml

#清空并打包
mvn clean package
