一、Maven基础回顾
1.1 Maven的好处
- 节省磁盘空间
- 可以一键构建
- 可以跨平台
- 应用在大型项目时可以提高开发效率
1.2 三种仓库
- 本地仓库
- 远程仓库(私服)
- 中央仓库
1.3 常见的命令
compile
test
package
install
deploy
clean
1.4 坐标的书写规范
groupId
:公司或组织域名的倒序artifactId
:项目名或模块名version
:版本号
1.5 添加坐标的方式
- 在本地仓库中搜索
- 互联网上搜索。http://www.mvnrepository.com/
1.6 依赖范围
compile
test
runtime
provided
二、SSM框架基础案例实现
2.1 准备数据库
创建名为
maven
的数据库,并导入一下sql语句SET FOREIGN_KEY_CHECKS=0; DROP TABLE IF EXISTS `items`; CREATE TABLE `items` ( `id` int(10) NOT NULL auto_increment, `name` varchar(20) default NULL, `price` float(10,0) default NULL, `pic` varchar(40) default NULL, `createtime` datetime default NULL, `detail` varchar(200) default NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8; INSERT INTO `items` VALUES ('1', '传智播客', '1000', null, '2018-03-13 09:29:30', '带我走上人生巅峰'); INSERT INTO `items` VALUES ('2', '黑马310', null, null, '2018-03-28 10:05:52', '插入测试'); INSERT INTO `items` VALUES ('3', '黑马307', '199', null, '2018-03-07 10:08:04', '插入测试'); INSERT INTO `items` VALUES ('7', '插入测试', null, null, null, null); INSERT INTO `items` VALUES ('8', '插入测试', null, null, null, null);
2.2 创建Maven工程(webapp)
2.2.1 知识储备(直接依赖和传递依赖)
在jar包导入的过程中,可能会出现,多个jar包同时依赖相同的jar包,可能造成冲突。依赖又分为:
- 直接依赖:项目中直接导入的jar包,就是该项目的直接依赖包。
- 传递依赖:项目中没有直接导入的jar包,可以通过项目直接依赖jar包传递到项目中
依赖调节的原则:
第一声明者优先原则
- 以坐标声明的顺序为准
路径近者优先原则
- 直接依赖路径比传递依赖路径近,最终项目中的jar包会是路径近的直接依赖jar包。
直接排除法
- 直接在坐标下使用
exlusion
标签
- 直接在坐标下使用
2.2.2 定义pom.xml
- 锁定依赖版本
- 添加依赖

三、Maven工程的拆分和聚合
- 继承:创建一个parent工程将所需的依赖全都配置到父工程的pom.xml文件中
- 聚合:聚合多个模块运行
3.0 概念:继承和聚合
3.0.1 继承
- 继承是为了消除重复,如果将
dao
、service
、web
分开创建独立的工程则每个工程的pom.xml
文件中的内容存在重复,比如:设置编译版本、锁定 spring 的版本的等,可以将这些重复的 配置提取出来在父工程的pom.xml
中定义。
3.0.2 聚合
- 项目开发通常是分组分模块开发,每个模块开发完成要运行整个工程需要将每个模块聚合在 一起运行,比如:
dao
、service
、web
三个工程最终会打一个独立的 war 运行。
3.1 parent父工程(project)
- 选择骨架创建父工程。骨架选:
maven-archetype-site
- 打包方式选择
pom
。 - 或者不用骨架创建父工程,在父工程下创建模块,父工程的pom文件会自动引入子模块,并设置打包方式为
pom
- 将jar包依赖全部导入父工程
pom.xml
pom.xml
<?xml version="1.0" encoding="UTF-8"?>
<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>
<!--工程和模块的区别
工程不等于完整的项目,模块也不等于完整的项目,一个完整的项目看的是代码,代码完整,就可以说
这是一个完整的项目。
和此项目是工程还是模块没有关系
工程天生只能使用自己内部资源,工程天生是独立的,后天可以和其他工程或模块建立关联关系。
模块天生不是独立的,模块天生属于父工程的,模块一旦创建,所有父工程的资源都可以使用。
父子工程之间,子模块天生集成父工程,可以使用父工程所有资源。
子模块之间天生是没有任何关系的
父子工程之间不用建立关系,继承关系是先天的,不需要手动建立。
平级之间的引用叫依赖,依赖不是先天的,依赖是需要后天建立的。

3.5 运行方式
3.5.1 方式1
方法 1:在 ssm_web 工程的 pom.xml 中配置 tomcat 插件运行
- 运行 ssm_web 工程它会从本地仓库下载依赖的 jar 包,所以当 ssm_web 依赖的 jar 包内容修 改了必须及时发布到本地仓库,比如:ssm_web 依赖的 ssm_service 修改了,需要及时将ssm_service 发布到本地仓库。
3.5.2 方式2 (推荐)
方法 2:在父工程的 pom.xml 中配置 tomcat 插件运行,自动聚合并执行
- 推荐方法 2,如果子工程都在本地,采用方法 2 则不需要子工程修改就立即发布到本地仓库, 父工程会自动聚合并使用最新代码执行。
- 注意:如果子工程和父工程中都配置了 tomcat 插件,运行的端口和路径以子工程为准。
