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>

运行配置

点击Run-->Edit Configurations

点击+号，选择Maven ，

输入信息

Name 给运行配置取的名称

Working directory(工程目录)

Command line 命令 tomcat7:deploy 或 tomcat7:redeploy

点击确定，保存。

在Run菜单下找到刚做好的配置，运行
