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>
