配置SpringBoot方便的切换jar和war的方法示例

<packaging>${pom.package}</packaging>

<!-- 作用是打war包的时候，不带版本号 -->
<finalName>${pom.packageName}</finalName>

<!--加入plugin-->
<plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-war-plugin</artifactId>
 <version>3.2.2</version>
 <configuration>
  <!--如果想在没有web.xml文件的情况下构建WAR，请设置为false。-->
  <failOnMissingWebXml>false</failOnMissingWebXml>
 </configuration>
</plugin>
