maven热部署到tomcat

1添加tomcat用户，在conf/tomcat-user.xml文件下添加一个tomcat用户

	<role rolename="manager-gui"/>
	<role rolename="manager-script"/>
	<user username="tomcat" password="123456" roles="manager-gui, manager-script"/>

启动tomcat后，可以进入后台

2在Maven项目pom.xml中配置tomcat7的插件

        <plugin>
    		<groupId>org.apache.tomcat.maven</groupId>
    		<artifactId>tomcat7-maven-plugin</artifactId>
    		<version>2.2</version>
    		<configuration>
    			<url>http://localhost:8080/manager/text</url>
    			<username>tomcat</username>
    			<password>123456</password>
    		</configuration>
    	</plugin>

3项目右键，run as

如果项目已经存在，则用tomcat7:redeploy命令
