maven 热部署 eclipse

在pom.xml 加入了个tomcat7的plugin 之后 使用maven debug  的 tomcat7:run的命令启动时，修改了Java类 就不会重启，太给力啦

<plugin>
                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>
                <version>2.1</version>
                <configuration>
                    <port>8080</port>
                    <path>/ibicnCloud-web</path>
                    <uriEncoding>UTF-8</uriEncoding>
                    <server>tomcat7</server>
                </configuration>
            </plugin>
