前言

本系列主要包含使用SSM框架从0开始实战一个项目的流程，本项目选用的开发工具是STS，选择用maven聚合工程搭建，本章内容主要讲解如何创建maven聚合工程

项目目录结构

logistics-parent：父工程，打包方式pom，管理jar包的版本 | 项目中所有的工程都应该继承父工程 |--logistics-common：通用的工具类 打包方式jar |--logistics-manager：服务工程。pom工程 |--logistics-manager-pojo：打包方式jar |--logistics-manager-service：打包方式jar |--logistics-manager-dao：打包方式jar |--logistics-manager-web：打包方式war

依赖关系图

撘建项目

logistics-parent

创建项目 创建成功 管理依赖 我们在pom.xml文件统一管理整个项目的j依赖的jar包的版本，pom.xml文件内容如下，<dependencyManagement>只管理版本，不实际依赖。<dependency>才实际依赖。

logistics-common

创建项目 配置依赖 接下来，我们来给logistics-common工程的pom.xml文件添加依赖，common顾名思义，就是大家都会调用的，像公共组件。我们从logistics-parent工程中复制公共组件的依赖到logistics-common的pom.xml文件当中，logistics-common的pom.xml文件的内容如下，由于logistics-parent工程中定义了定义版本号，因此我们在logistics-common工程中不用定义组件的版本了。保存后，maven会自动下载相关依赖。

<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> <parent> <groupId>com.yjn</groupId> <artifactId>logistics-parent</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <groupId>com.yjn</groupId> <artifactId>logistics-common</artifactId> <version>0.0.1-SNAPSHOT</version> <dependencies> <!-- 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-net</groupId> <artifactId>commons-net</artifactId> </dependency> <!-- Jackson Json处理工具包 --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> </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> </dependencies> </project>

logistics-manager

创建项目 工程类型设为pom类型，父工程设为logistics-parent 配置依赖 建完之后，我们在logistics-manager的pom.xml文件中添加对logistics-common的依赖。

<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> <parent> <groupId>com.yjn</groupId> <artifactId>logistics-manager</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <artifactId>logistics-manager-dao</artifactId> <dependencies> <dependency> <groupId>com.yjn</groupId> <artifactId>logistics-manager-pojo</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> <!-- Mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> </dependency> <dependency> <groupId>com.github.miemiedev</groupId> <artifactId>mybatis-paginator</artifactId> </dependency> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> </dependency> <dependency> <groupId>com.github.jsqlparser</groupId> <artifactId>jsqlparser</artifactId> </dependency> <!-- MySql --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!-- 连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> </dependency> </dependencies> </project>

四个子模块

子模块的父工程都是logistics-manager 子模块的创建不再是maven project,我们选择maven module,右键logistics-manager项目创建子模块

logistics-manager-pojo

项目创建 不需要修改，默认即可 配置依赖 此项目不需要添加依赖

logistics-manager-dao

项目创建 类似logistics-manager-pojo，不再赘述 配置依赖 建完logistics-manager-pojo之后，我们打开logistics-manager-dao模块的pom.xml文件，并在其中添加对logistics-manager-pojo的依赖，另外由于dao层需要Mybatis、Mysql、分页、连接池的包，因此我们在pom.xml文件中添加对这些的依赖。

<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> <parent> <groupId>com.yjn</groupId> <artifactId>logistics-manager</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <artifactId>logistics-manager-dao</artifactId> <dependencies> <dependency> <groupId>com.yjn</groupId> <artifactId>logistics-manager-pojo</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> <!-- Mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> </dependency> <dependency> <groupId>com.github.miemiedev</groupId> <artifactId>mybatis-paginator</artifactId> </dependency> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> </dependency> <dependency> <groupId>com.github.jsqlparser</groupId> <artifactId>jsqlparser</artifactId> </dependency> <!-- MySql --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!-- 连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> </dependency> </dependencies> </project>

logistics-manager-service

项目创建 同上 配置依赖 需要配置依赖dao项目

<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> <parent> <groupId>com.yjn</groupId> <artifactId>logistics-manager</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <artifactId>logistics-manager-service</artifactId> <dependencies> <!-- service 依赖 dao --> <dependency> <groupId>com.yjn</groupId> <artifactId>logistics-manager-dao</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jms</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> </dependency> </dependencies> </project>

logistics-manager-web

创建项目 工程类型设为war类型，父工程设为logistics-manager 创建完如果有报错，是因为缺少web.xml文件，手动创建一个即可 配置依赖 需要配置对service模块的依赖

<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> <parent> <groupId>com.yjn</groupId> <artifactId>logistics-manager</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <artifactId>logistics-manager-web</artifactId> <packaging>war</packaging> <dependencies> <!-- 依赖service --> <dependency> <groupId>com.yjn</groupId> <artifactId>logistics-manager-service</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> <!-- JSP相关 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <scope>provided</scope> </dependency> <!-- shiro相关的依赖 --> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-spring</artifactId> </dependency> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-ehcache</artifactId> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> </dependency> </dependencies> </project>

到这里整个项目的结构就搭建完了
