如何在war任务中引用classpathref？

   <plugins>
       <plugin>
           <groupId>org.apache.maven.plugins</groupId>
           <artifactId>maven-war-plugin</artifactId>
           <version>3.3.1</version>
           <configuration>
               <archive>
                   <manifest>
                       <addClasspath>true</addClasspath>
                       <classpathPrefix>lib/</classpathPrefix>
                    </manifest>
                </archive>
            </configuration>
        </plugin>
    </plugins>
</build>

   <context-param>
       <param-name>contextConfigLocation</param-name>
       <param-value>classpath*:applicationContext.xml</param-value>
