搭建聚合工程教案
淘淘商城第一天
1 课程安排
项目架构,使用maven架构一个分布式项目,SSM整合,搭建一个商品后台
2 淘淘商城后台架构
2.1 项目架构
项目管理:Maven
taotao-parent: pom工程,只记录jar包的定位
taotao-common: jar包工程, 是整个电商项目的一个工具类,
taotao-manager 聚合工程
Taotao-manager-pojo
Taotao-manager-mapper DAO 持久层
Taotao-manager-service 业务逻辑
Taotao-manager-web springmvc里的controller类
2.2 环境搭建
2.2.1 Eclipse环境搭建
启动的时候会报错,
电脑中,安装过oracle,Oracle默认的jdk是1.3版本
%JAVA_HOME%\bin;F:\oracle\product\10.2.0\db_1\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;E:\mysql\bin;E:\software\mysql\bin;E:\software\Tortois\bin;E:\software\svnServer\bin;E:\maven\bin;
2.2.1.1 工作空间
2.2.1.2 创建本地仓库
2.2.1.3 启动Eclipse
减压Eclipse压缩包,选中上面配置好的工作空间
3 创建taotao-parent
3.1 修改pom文件

Pom工程,只需要定义版本号和jar包工程.
4 创建taotao-common工程
搭建成为一个jar工程.就相当于把工程打成jar包的形式.
4.1 修改pom文件
依赖,依赖传递,继承.
因为我们依赖了taotao-parent工程,所以我们不需要写版本号了
<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/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.taotao.common</groupId> <artifactId>taotao-common</artifactId> <version>0.0.1-SNAPSHOT</version> <parent> <groupId>com.taotao.parent</groupId> <artifactId>taotao-parent</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <dependencies> <!--jedis --> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.6.0</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-pool2</artifactId> <version>2.4.2</version> </dependency> <!-- 单元测试 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <scope>test</scope> </dependency> <!--日志处理 --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> </dependency> <!-- Jackson Json处理工具包 --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> </dependency> <dependency> <groupId>org.apache.clerezza.ext</groupId> <artifactId>org.json.simple</artifactId> <version>0.4</version> </dependency> <!-- httpclient --> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> </dependency> <!-- 时间操作组件 --> <dependency> <groupId>joda-time</groupId> <artifactId>joda-time</artifactId> </dependency> <!-- Apache工具组件 --> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-io</artifactId> </dependency> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.2.2</version> </dependency> </dependencies> </project>

5.9 创建web.xml
5.10 修改web.xml文件
<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="taotao" version="2.5"> <display-name>taotao-manage</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> </web-app>
5.11 启动taotao-manager项目
5.11.1 创建index.jsp页面
5.11.2 配置一下taotao-manage下的pom文件
添加tomcat插件
<build> <!-- 配置插件 --> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <configuration> <port>8080</port> <path>/</path> </configuration> </plugin> </plugins> </build>
5.11.3 启动命令
5.12 错误总结
在你的资源库中没有找到taotao-parent这个pom文件
解决方式
需要安装taotao-parent项目到资源库中
错误
解决错误,把taotao-common这个工程安装到本地仓库.
5.13 截图留念
6 SVN上传
6.1 上传taotao-manager项目
6.2 使用svn下载项目
把svn上下载下来的项目,转换成为maven项目
聚合工程的关系图
作为一个真正的程序员,首先应该尊重编程,热爱你所写下的程序,他是你的伙伴,而不是工具。
