Maven项目热部署到Tomcat容器下

第一步: 配置Tomcat的登陆的用户名与密码
在 apache-tomcat-7.0.33\conf\ tomcat-users.xml，第40行添加如下:

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

如果使用默认的8080端口，下面的端口号不用修改

第二步:添加Tomcat插件到Maven项目

        <plugin>
            <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat7-maven-plugin</artifactId>
            <version>2.2</version>
            <configuration>
                <port>8082</port>
                <url>http://localhost:8082/manager/text</url>
                <server>tomcat</server>
                <username>tomcat</username>
                <password>123456</password>
            </configuration>
        </plugin>

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <configuration>
                <source>1.6</source>
                <target>1.6</target>
                <encoding>UTF-8</encoding>
            </configuration>
        </plugin>
