maven tomcat:run指定tomcat7:
<repositories> <repository> <id>people.apache.snapshots</id> <url>http://repository.apache.org/content/groups/snapshots-group/</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>apache.snapshots</id> <name>Apache Snapshots</name> <url>http://repository.apache.org/content/groups/snapshots-group/</url> <releases> <enabled>false</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </pluginRepository> </pluginRepositories><plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat6-maven-plugin</artifactId> <version>2.0-SNAPSHOT</version> <configuration> <path>/</path> </configuration> </plugin> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.0-SNAPSHOT</version> <configuration> <path>/</path> </configuration> </plugin> </plugins

?过程中遇到了一个情况，就是打成war包放到webapps下面运行时正常的，但是用tomcat:run会报错：org.springframework.web.filter.DelegatingFilterProxy cannot be cast to javax.servlet.Filter；
检查一下：
pom.xml文件编辑器（一般要装插件才能看到）下面的dependency hierarchy 里面，在右边框图里面找到servlet-api.jar，选中后在左边，右键->exclude maven artifact，去除依赖关系。
