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>
