基础工程搭建

项目根目录

创建一个空工程xuecheng-plus即项目的根目录,进入Project Structure检查jdk是否配置正确
在这里插入图片描述

新增.gitignore文件用来设置工程中不需要向仓库提交的内容

HELP.md
target/
!.mvn/wrapper/maven-wrapper.jar
!**/src/main/**
!**/src/test/**
#### STS ###
.apt_generated
.classpath
.factorypath
.project
.settings
.springBeans
.sts4-cache
#### IntelliJ IDEA ###
.idea
*.iws
*.iml
*.ipr
#### NetBeans ###
/nbproject/private/
/nbbuild/
/dist/
/nbdist/
/.nb-gradle/

#### VS Code ###
.vscode/

使用Maven来进行项目各大模块的管理和构建,整个项目分为父工程模块、基础工程模块和微服务工程模块三大类,每一种类的工程都有不同的作用

在这里插入图片描述

构建父工程模块(parant)

父工程负责对项目中所依赖包的版本进行管理

第一步: 选择Spring Initalizr的方式新建父工程模块,填写模块名xuecheng-plus-parent和包名com.xuecheng等信息

在这里插入图片描述

第二步: 创建成功后删除工程中多余的文件

在这里插入图片描述

第二步: 依赖管理定义,由于父工程中不用编写代码所以不用去依赖其它的包,它的作用就是限定子工程依赖包的版本

  • 确定父工程为一个POM工程,对子工程进行聚合管理
<packaging>pom</packaging>
  • 确定项目所依赖的包及其版本号
<properties>
    <java.version>1.8</java.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <spring-boot.version>2.3.7.RELEASE</spring-boot.version>
    <spring-cloud.version>Hoxton.SR9</spring-cloud.version>
    <org.mapstruct.version>1.3.1.Final</org.mapstruct.version>
    <spring-cloud-alibaba.version>2.2.6.RELEASE</spring-cloud-alibaba.version>
    <org.projectlombok.version>1.18.8</org.projectlombok.version>
    <javax.servlet-api.version>4.0.1</javax.servlet-api.version>
    <fastjson.version>1.2.83</fastjson.version>
    <druid-spring-boot-starter.version>1.2.8</druid-spring-boot-starter.version>
    <mysql-connector-java.version>8.0.30</mysql-connector-java.version>
    <mybatis-plus-boot-starter.version>3.4.1</mybatis-plus-boot-starter.version>
    <commons-lang.version>2.6</commons-lang.version>
    <minio.version>8.4.3</minio.version>
    <xxl-job-core.version>2.3.1</xxl-job-core.version>
    <swagger-annotations.version>1.5.20</swagger-annotations.version>
    <commons-lang3.version>3.10</commons-lang3.version>
    <okhttp.version>4.8.1</okhttp.version>
    <swagger-spring-boot-starter.version>1.9.0.RELEASE</swagger-spring-boot-starter.version>
    <elasticsearch.version>7.12.1</elasticsearch.version>
</properties>
  • 编写dependencyManagement来限定项目中所依赖包的版本,此时并不会真正导入依赖,子工程需要的时候还需要手动导入但时依赖的版本号已经指定了
<dependencyManagement>

构建基础工程模块(base)

基础工程的职责是提供一些系统架构所需要的基础类库以及一些工具类库

第一步: 选择Spring Initalizr的方式新建基础工程模块,填写模块名xuecheng-plus-base和包名com.xuecheng.base等信息,最后同样删除多余的文件

在这里插入图片描述

第二步: 继承父类工程即,以当前工程的pom.xml文件为起点找到父工程的pom.xml文件

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <!--找到父工程的pom.xml文件-->

微服务工程模块

分别从业务和技术方面划分模块，一般每个模块构建一个微服务,每个微服务工程依赖基础工程，间接继承父工程

  • 主要包括内容管理服务、媒资管理服务、搜索服务、订单支付服务等
