maven的作用

1.管理jar包及依赖、工程之间的依赖

2.项目构建。

3.工程聚合、继承、依赖

Maven的工程类型

1.war包工程

2.Jar包工程

3.Pom工程

后台管理系统工程结构：

taotao-parent （pom）-- 管理依赖jar包的版本，全局，公司级别

|--taotao-common (jar)--- 通用组件、工具类

|--taotao-manage (pom)-- 后台系统

|--com.taotao.manage.web(war)

|--com.taotao.manage.service(jar)

|--com.taotao.manage.mapper(jar)

|--com.taotao.manage.pojo(jar)

1.创建taotao-parent父工程

1.new a maven project

2.Create a simple project

3.Packaging选择pom（聚合项目）

4.修改pom.xml

8. <groupId>com.taotao</groupId>
9. <artifactId>taotao-common</artifactId>
10. <version>0.0.1-SNAPSHOT</version>
11. </project>

7.工程点击右键→maven→update Project Configuration

3.创建taotao-manager

1.new a maven project

1.右键taotao-manager---new Maven Module

2.Create a simple project

3.Packaging选择jar（被其他工程所引用）

4.Group id与taotao-parent的Group id一致（同一组织）

5.pom文件不需要修改，不依赖任何jar包

5.创建taotao-manager-mapper

1.右键taotao-manager---new Maven Module

2.Create a simple project

3.Packaging选择jar（被其他工程所引用）

4.Group id与taotao-parent的Group id一致（同一组织）

7.创建taotao-manager-web

1.右键taotao-manager---new Maven Module

2.Create a simple project

3.Packaging选择war

4.Group id与taotao-parent的Group id一致（同一组织）

5.pom文件修改（依赖taotao-manager-service）。及添加jstl、jsp、servlet、commons-fileupload等依赖

6.在webapp下创建WEB-INF，继续创建web.xml

[html] view plain copy

1. <?xml version="1.0" encoding="UTF-8"?>
2. <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
3. xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
4. xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
5. id="taotao" version="2.5">
6. <display-name>taotao-manager</display-name>
7. <welcome-file-list>
8. <welcome-file>index.html</welcome-file>
9. <welcome-file>index.htm</welcome-file>
10. <welcome-file>index.jsp</welcome-file>
11. <welcome-file>default.html</welcome-file>
12. <welcome-file>default.htm</welcome-file>
13. <welcome-file>default.jsp</welcome-file>
14. </welcome-file-list>
16. </web-app>

运行测试

要运行工程，需要运行聚合工程也就是taotao-manager。

1.在taotao-manager工程的pom文件中添加如下内容：

[html] view plain copy

1. <build>
2. <!-- 配置插件 -->
3. <plugins>
4. <plugin>
5. <groupId>org.apache.tomcat.maven</groupId>
6. <artifactId>tomcat7-maven-plugin</artifactId>
7. <configuration>
8. <port>8080</port>
9. <path>/</path>
10. </configuration>
11. </plugin>
12. </plugins>
13. </build>

2.使用maven命令：

clean tomcat7:run

注意：

（1）需要把taotao-parent工程安装到本地仓库。Install

（2）需要把taotao-common安装到本地仓库。
