淘淘商城第一天：使用IDEA搭建基于maven的SSM聚合项目

目录结构如下所示：

环境准备：

maven3.5.2

jdk1.7

不知版本的idea(别打我，我真不知道！！！)

第一步：创建一个empty project,命名为taotao

第二步：创建所有项目的父项目taotao-parent

新建一个module

选选择本地的jdk之后，注意直接点击next

配置module

给该模块命名：

以下为该模块的pom.xml文件，具体注解如下所示：

<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</groupId>
  <artifactId>taotao-parent</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>pom</packaging>

  <name>taotao-parent</name>
  <url>http://maven.apache.org</url>

</project>

第三步：创建taotao-common(通用模块)

基本步骤与创建taotao-common一致，唯一的不同点如下图所示：

千万注意目录结构，该模块不是taotao-parent的子目录！！！

该项目的pom.xml配置如下：

<?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">
    <parent>
        <artifactId>taotao-parent</artifactId>
        <groupId>com.taotao</groupId>
        <version>1.0-SNAPSHOT</version>
        <relativePath>../taotao-parent/pom.xml</relativePath>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <packaging>jar</packaging>
    <artifactId>taotao-common</artifactId>

    <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>
        <!-- httpclient -->
        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</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>

第四步：创建taotao-manager

taotao-manager的创建和taotao-common的创建一样

taotao-manager的pom.xml：

第五步：创建taotao-manager的四个子模块，也就是我们所熟悉的四层结构：

taotao-manager-pojo的创建:

taotao-mapper和taotao-service的创建和taotao-pojo的创建过程一毛一样，请自行脑补，接下来我贴一下这哥仨的pom.xml:

taotao-manager-pojo的pom.xml:

taotao-manger-mapper的pom.xml，你只需要在对应的位置添加以下代码即可，千万别删除原本的配置文件中滴内容！！！！:

<dependency>
    <groupId>com.taotao</groupId>
    <artifactId>taotao-manager-pojo</artifactId>
    <version>1.0-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>
<!-- MySql -->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
</dependency>
<!-- 连接池 -->
<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
</dependency>

<packaging>jar</packaging>

tao-manager-service的pom.xml文件(记住我刚刚强调的内容，可增加，别删除！！！):

<dependency>
    <groupId>com.taotao</groupId>
    <artifactId>taotao-manager-mapper</artifactId>
    <version>1.0-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-webmvc</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jdbc</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-aspects</artifactId>
</dependency>

<packaging>jar</packaging>

好了，接下来到要点了，创建taotao-manager-web模块：

注意目录：

需要添加的依赖关系为：

对了！！！还有一点，记住修改!!

第六步：将taotao-parent,taotao-common,taotao-manager安装到本地maven仓库：

打开cmd，在taotao-parent,taotao-common,taotao-manager的路径下执行mvn clean install进行安装：

第七步：创建jsp文件，运行项目！！

随便写一些东西在jsp里面

分别点击apply,ok
