maven

1.在项目的pom.xml中添加如下插件：

org.apache.tomcat.maventomcat7-maven-plugin2.2http://localhost:8080/manager/texttomcatserver /restful tomcat123456 ps: : 本地tomcat的路径，默认配置为 http://localhost:{port}(自己的端口号)/manager/text :给当前tomcat分配一个ID，后面有用； ： 访问路径； / : 给当前tomcat分配用户名和密码； 如果需要更新war包的话，应该这样配置： org.apache.tomcat.maventomcat7-maven-plugin2.2 http://localhost:8080/manager/texttomcatserver /restful tomcat123456true 如果不添加会出现一下异常：
