一、.使用ieda 建立一個webapp 工程 如下圖：
二、加入spring mvc 等一下依賴包，配置等，如下：
1. 工程結構如下：
2. pom.xml 檔案完整如
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion><groupId>com.harris.app</groupId> <artifactId>tomcatci</artifactId> <packaging>war</packaging> <version>1.0-SNAPSHOT</version> <name>tomcatci Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <!-- spring版本號 --> <spring.version>4.0.2.RELEASE</spring.version> </properties> <dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> <!-- 表示開發的時候引入，釋出的時候不會載入此包 --><scope>test</scope> </dependency> <!-- spring核心包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-oxm</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <!-- 匯入java ee jar 包 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>7.0</version> </dependency> <!-- JSTL標籤類 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 映入JSON --> <dependency> <groupId>org.codehaus.jackson</groupId> <artifactId>jackson-mapper-asl</artifactId> <version>1.9.13</version> </dependency> <!-- 上傳元件包 --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.9</version> </dependency> </dependencies> <build> <finalName>${project.artifactId}</finalName> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <!-- 是否替換資源中的屬性--> <filtering>false</filtering> </resource> <resource> <directory>src/main/resources</directory> </resource> </resources> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <configuration> <url>http://10.11.3.135:8080/manager/text</url> <server>tomcat7</server> <path>/${project.artifactId}</path> <update>true</update> </configuration> </plugin> </plugins> </build> </project>
以上需要注意是在加入的maven 的外掛處的url 地址ip為虛機的ip，server處的tomcat7要與下面在maven中配置的server要一樣
3. spring-mvc.xml完整檔案如下：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"> <!--避免IE執行AJAX時，返回JSON出現下載檔案 --> <bean id="mappingJacksonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html;charset=UTF-8</value> </list> </property> </bean> <!-- 啟動SpringMVC的註解功能，完成請求和註解POJO的對映 --> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <!-- JSON轉換器 --> <ref bean="mappingJacksonHttpMessageConverter" /> </list> </property> </bean> <!-- 對靜態資源的訪問 --> <!-- <mvc:resources mapping="/js/**" location="/js/" /><mvc:resources mapping="/css/**" location="/css/" /> --> <!-- 自動掃描該包，使SpringMVC認為包下用了@controller註解的類是控制器 --> <context:component-scan base-package="com.harris.app.controller" /> <!-- 添加註解驅動 --> <mvc:annotation-driven enable-matrix-variables="true" /> <!-- 允許對靜態資原始檔的訪問 --> <mvc:default-servlet-handler /> <!-- 定義跳轉的檔案的前後綴 ，檢視模式配置 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 這裡的配置我的理解是自動給後面action的方法return的字串加上字首和字尾，變成一個 可用的url地址 --> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> <!-- 配置檔案上傳，如果沒有使用檔案上傳可以不用配置，當然如果不配，那麼配置檔案中也不必引入上傳元件包 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <!-- 預設編碼 --> <property name="defaultEncoding" value="utf-8" /> <!-- 檔案大小最大值 --> <property name="maxUploadSize" value="10485760000" /> <!-- 記憶體中的最大值 --> <property name="maxInMemorySize" value="40960" /> </bean> </beans>4.spring-mybatis.xml 完整檔案如下：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd"> <!-- 自動掃描 --> <context:component-scan base-package="com.harris" /> </beans>
5.web.xml 完整檔案如下：
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"> <!-- Spring和mybatis的配置檔案 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mybatis.xml</param-value> </context-param> <!-- 編碼過濾器 --> <filter> <filter-name>encodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <async-supported>true</async-supported> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- Spring監聽器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止Spring記憶體溢位監聽器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- Spring MVC servlet --> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <!-- 此處可以可以配置成*.do，對應struts的字尾習慣 --> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/index.html</welcome-file> <welcome-file>/index.jsp</welcome-file> </welcome-file-list> </web-app>
6.HelloController.java 完整檔案如下：
package com.harris.app.controller; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import javax.servlet.http.HttpServletRequest; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Map; @Controller public class HelloController { private static SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); @RequestMapping("/hello") public String toIndex(HttpServletRequest request, Model model) { String name = request.getParameter("name"); model.addAttribute("name", name); model.addAttribute("time", sdf.format(new Date())); Map<String, String> map = System.getenv(); model.addAttribute("serviceSource", map.get("TOMCAT_SERVER_ID")); return "hello"; } }
7. hello.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <META HTTP-EQUIV="Pragma" CONTENT="no-cache"> <META HTTP-EQUIV="Cache-Control" CONTENT="no-cache"> <META HTTP-EQUIV="Expires" CONTENT="0"> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Hello</title> <style> .importentspan{ color:#00F; } </style> </head> <body>您好${name}，這是來自<span class="importentspan">${serviceSource}</span>的問候！${time} </body> </html>
三、 設定maven ，在你的maven安裝目錄conf中的settings.xml中，在servers中加入以下內容
<server>
<id>tomcat7</id>
<username>harris</username>
<password>123456</password>
</server>四、先來到你的虛擬機器中,先下載一個包含了jdk8的tomcat7.077映象
docker pull tomcat:7.0.77-jre8 2. 從其它的tomcat安裝檔案中複製兩個檔案到一個目錄下，我這為 /cloud/tomcatci ，兩個檔案為server.xml, tomcat-user.xml
3.修改server.xml
此處加入URIEncoding="UTF-8",儲存
4. 修改tomcat-user.xml,加入使用者和角色
這裡的username 和password和你maven中加入的server 中的一樣，儲存
5.這裡開始製作tomcat映象，先建立一個Dockerfile檔案，內容如下：
#基礎映象
FROM tomcat:7.0.77-jre8
#作者
MAINTAINER test
#定義工作目錄
ENV WORK_PATH /usr/local/tomcat/conf
#定義要替換的檔名
ENV USER_CONF_FILE_NAME tomcat-users.xml
#定義要替換的server.xml檔名
ENV SERVER_CONF_FILE_NAME server.xml
#刪除原檔案tomcat-users.xml
RUN rm $WORK_PATH/$USER_CONF_FILE_NAME
#複製檔案tomcat-users.xml
COPY ./$USER_CONF_FILE_NAME $WORK_PATH/
#刪除原檔案server.xml
RUN rm $WORK_PATH/$SERVER_CONF_FILE_NAME
#複製檔案server.xml
COPY ./$SERVER_CONF_FILE_NAME $WORK_PATH/6. cd 到/cloud/tomcatci目錄下 ，一共有三個檔案 Dockerfile,server.xml,tomcat-user.xml，執行以下命令，構建映象：
docker build -t tomcatci .7. 啟動一個tomcat例項
docker run --name=tomcat001 -p 8080:8080 -e TOMCAT_SERVER_ID=tomcat_server_001 -idt tomcatci啟動完後，可以在瀏覽中訪問http://10.11.3.135:8080 ,就可以看到tomcat的介面
8.釋出工程到tomcat中，開啟命令列介面,切換到你工程目錄，執行maven的構建命令，前題你得將maven加入到系統環境變數中
mvn clean package -U -Dmaven.test.skip=true tomcat7:redeploy
看到打包成包後 ,進入到你tomcat中的Manager App 中就會看你的工程名稱
再次訪問http://10.11.3.135:8080/tomcatci/hello?name=test,就會看到以下介面：
可以再次修改工程內容，再次構建部署檢視變化
