怎么在maven工程中配置tomcat插件

在maven工程,pom.xml文件中project节点下添加如下代码:

  <build>      <pluginManagement>          <plugins>              <!-- 配置Tomcat插件 -->              <plugin>                  <groupId>org.apache.tomcat.maven</groupId>                  <artifactId>tomcat7-maven-plugin</artifactId>                  <version>2.2</version>                  <configuration>                      <port>8082</port>                      <path>/</path>                  </configuration>              </plugin>          </plugins>      </pluginManagement>    </build>
