IntelliJ IDEA使用maven实现tomcat的热部署

在tomcat的conf目录 tomcat-users.xml配置以下内容（<tomcat-users>标签内</tomcat-users>），用于部署：

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

启动tomcat，访问 http:ip:8080/manager 验证tomcat用户是否配置成功

在maven工程的pom.xml中配置插件

            <plugin>                <groupId>org.apache.tomcat.maven</groupId>                <artifactId>tomcat7-maven-plugin</artifactId>                <configuration>                    <port>8080</port>                    <path>/mvc</path>                    <url>http://192.168.43.128:8080/manager/text</url>                    <username>tomcat</username>                    <password>tomcat</password>                </configuration>            </plugin>
