1、先要选取一个基板docker镜像，此处选用tomcat:8-jre8
2、通过基板镜像，build一个自有镜像：
Dockerfile：
FROM tomcat:8-jre8 MAINTAINER "Liu Li <lich@lichdiamond.win>" ADD settings.xml /usr/local/tomcat/conf/ ADD tomcat-users.xml /usr/local/tomcat/conf/
settings.xml:
<?xml version="1.0" encoding="UTF-8"?> <settings> <servers> <server> <id>TomcatServer</id> <username>admin</username> <password>adm123</password> </server> </servers>
tomcat-users.xml:
<?xml version=‘1.0‘ encoding=‘utf-8‘?> <tomcat-users> <role rolename="manager-gui"/> <role rolename="manager-gui"/> <role rolename="manager-script"/> <user username="admin" password="adm123" roles="manager,manager-gui,manager-script" /> </tomcat-users>
这三个文件放在同一个文件夹里，然后在那个文件夹里执行：
docker build -t my_tomcat:8-jre8 .
3、通过设定的自有镜像启动一个容器：
docker run -d -p 8080:8080 my_tomcat:8-jre8
访问ip：8080可以获得tomcat的欢迎页
ip/manager可以获得tomcat的管理页面：登录用户名密码在上面文件中配置
4、maven管理的工程中的pom文件中：
注：如果pom中带s的复数标签已有，只需要将内容添加到标签下即可：
比如：
文件中已经存在plugins标签，往其中添加：
<plugins>
<plugin>
<groupId>xxxxxxxxxxxxxxxxxx</groupId>
<artifactId>xxxxxxxxxxxxxxxxxx</artifactId>
<version>xxxxxxxxxxx</version>
</plugin>
.
.
.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
</plugin>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<port>8080</port>
<uriEncoding>UTF-8</uriEncoding>
<url>http://localhost:8080/manager/text</url>
<username>admin</username>
<password>adm123</password>
<path>/${project.artifactId}</path>
</configuration>
</plugin>
</plugins>文件中存在properties标签时：
<properties> . . . <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.deploy>deploy</project.deploy> <project.tomcat.version>8.0.0-RC5</project.tomcat.version> </properties>
文件中存在dependencies标签：
<dependencies>
<dependency>
<groupId>xxxxxxxxxx</groupId>
<artifactId>xxxxxxxxxxxx</artifactId>
<version>xxxxxxxxxxxxx</version>
<scope>xxxxxxxxxxxx</scope>
</dependency>
.
.
.
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-servlet-api</artifactId>
<version>${project.tomcat.version}</version>
<scope>provided</scope>
</dependency>
</dependencies>pom.xml:
localhost改成你部署的主机的ip
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.deploy>deploy</project.deploy>
<project.tomcat.version>8.0.0-RC5</project.tomcat.version>
</properties>
<dependencies>
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>tomcat-servlet-api</artifactId>
<version>${project.tomcat.version}</version>
<scope>provided</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
</plugin>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<port>8080</port>
<uriEncoding>UTF-8</uriEncoding>
<url>http://localhost:8080/manager/text</url>
<username>admin</username>
<password>adm123</password>
<path>/${project.artifactId}</path>
</configuration>
</plugin>
</plugins>
</build>5、完成之后，在项目工程文件夹中执行：
含义：构建并将工程部署到tomcat中，跳过单元测试。
mvn -Dmaven.test.skip=true tomcat7:deploy -e
结果如：

我的工程名字叫busimgnt，此时访问：
我的ip:8080/busimgnt，我的index中只写了hello world，因此访问后得到了该字符串，这时候，热部署就完成了，下次打包之后，执行本命令，就可以将新包热部署。
