Mooc項目開發筆記（一）：搭建項目框架

一、創建父工程

1、創建sprigboot工程 Mooc

在idea開發工具中，使用 Spring Initializr 快速初始化一個 Spring Boot 模塊，版本使用：2.2.6.RELEASE

2、刪除 src 目錄

3、配置 pom.xml

修改版本爲 ：2.2.6.RELEASE

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

<artifactId>節點後面添加 pom類型

    <artifactId>mooc</artifactId>
    <packaging>pom</packaging>

4、在pom.xml中修改依賴信息

刪除pom.xml中的<dependencies>內容

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
            <exclusions>
                <exclusion>
                    <groupId>org.junit.vintage</groupId>
                    <artifactId>junit-vintage-engine</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>

添加 <properties>確定依賴的版本

<properties>
    <java.version>1.8</java.version>
    <guli.version>0.0.1-SNAPSHOT</guli.version>
    <mybatis-plus.version>3.0.5</mybatis-plus.version>
    <velocity.version>2.0</velocity.version>
    <swagger.version>2.7.0</swagger.version>
    <aliyun.oss.version>2.8.3</aliyun.oss.version>
    <jodatime.version>2.10.1</jodatime.version>
    <poi.version>3.17</poi.version>
    <commons-fileupload.version>1.3.1</commons-fileupload.version>
    <commons-io.version>2.6</commons-io.version>
    <httpclient.version>4.5.1</httpclient.version>
    <jwt.version>0.7.0</jwt.version>
    <aliyun-java-sdk-core.version>4.3.3</aliyun-java-sdk-core.version>
    <aliyun-sdk-oss.version>3.1.0</aliyun-sdk-oss.version>
    <aliyun-java-sdk-vod.version>2.15.2</aliyun-java-sdk-vod.version>
    <aliyun-java-vod-upload.version>1.4.11</aliyun-java-vod-upload.version>
    <aliyun-sdk-vod-upload.version>1.4.11</aliyun-sdk-vod-upload.version>
    <fastjson.version>1.2.28</fastjson.version>
    <gson.version>2.8.2</gson.version>
    <json.version>20170516</json.version>
    <commons-dbutils.version>1.7</commons-dbutils.version>
    <canal.client.version>1.1.0</canal.client.version>
    <docker.image.prefix>zx</docker.image.prefix>
    <cloud-alibaba.version>0.2.2.RELEASE</cloud-alibaba.version>
</properties>

配置 <dependencyManagement>鎖定依賴的版本，用於管理子模塊的依賴

        </dependency>
    </dependencies>
</dependencyManagement>

二、搭建service子模塊

1、在父工程mooc下面創建模塊service

在父工程名稱上右鍵，New->Model

選擇Maven工程，點擊Next

將子工程的ArtifactId設置爲service，一直點擊next

子模塊創建成功

2、添加模塊類型是pom

    <artifactId>service</artifactId>
    <packaging>pom</packaging>

3、添加項目需要的依賴

<dependencies>
    	 <!--之後使用時再打開註釋，否則開發過程中會報錯-->
        <!--<dependency>-->
            <!--<groupId>org.springframework.cloud</groupId>-->
            <!--<artifactId>spring-cloud-starter-netflix-ribbon</artifactId>-->
        <!--</dependency>-->

        <!--&lt;!&ndash;hystrix依賴，主要是用  @HystrixCommand &ndash;&gt;-->
        <!--<dependency>-->
            <!--<groupId>org.springframework.cloud</groupId>-->
            <!--<artifactId>spring-cloud-starter-netflix-hystrix</artifactId>-->
        <!--</dependency>-->

        <!--&lt;!&ndash;服務註冊&ndash;&gt;-->
        <!--<dependency>-->
            <!--<groupId>org.springframework.cloud</groupId>-->
            <!--<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>-->
        <!--</dependency>-->
        <!--&lt;!&ndash;服務調用&ndash;&gt;-->
        <!--<dependency>-->
            <!--<groupId>org.springframework.cloud</groupId>-->
            <!--<artifactId>spring-cloud-starter-openfeign</artifactId>-->
        <!--</dependency>-->

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <!--mybatis-plus-->
    <dependency>
        <groupId>com.baomidou</groupId>
        <artifactId>mybatis-plus-boot-starter</artifactId>
    </dependency>

    <!--mysql-->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>

    <!-- velocity 模板引擎, Mybatis Plus 代碼生成器需要 -->
    <dependency>
        <groupId>org.apache.velocity</groupId>
        <artifactId>velocity-engine-core</artifactId>
    </dependency>
	 <dependency>
	    <groupId>com.baomidou</groupId>
	    <artifactId>mybatis-plus-generator</artifactId>
	</dependency>
	
	    <!--swagger-->
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
    </dependency>

    <!--lombok用來簡化實體類：需要安裝lombok插件-->
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>

    <!--xls-->
    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi</artifactId>
    </dependency>

    <dependency>
        <groupId>org.apache.poi</groupId>
        <artifactId>poi-ooxml</artifactId>
    </dependency>

    <dependency>
        <groupId>commons-fileupload</groupId>
        <artifactId>commons-fileupload</artifactId>
    </dependency>

    <!--httpclient-->
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
    </dependency>
    <!--commons-io-->
    <dependency>
        <groupId>commons-io</groupId>
        <artifactId>commons-io</artifactId>
    </dependency>
    <!--gson-->
    <dependency>
        <groupId>com.google.code.gson</groupId>
        <artifactId>gson</artifactId>
    </dependency>

    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
    </dependency>
</dependencies>

4、刪除 src 目錄

我們使用的微服務開發模式，Service模塊下面是項目中各個服務的具體實現。Service模塊仍然作爲一個模塊容器，不做具體實現，所以這裏刪除src目錄。

三、搭建service-edu模塊

service-edu是我們這個項目中的服務模塊，其中包含我將要實現的講師管理功能。

1、在父工程service模塊下面創建子模塊service-edu

按照創建service模塊的步驟，在父工程service模塊下面創建子模塊service-edu

三、創建相關數據庫

先在創建一個名爲mooc的數據庫，然後在該數據庫中分別執行下面的資源文件中的SQL語句。
