总结

我们开发项目的第一步就是要搭建一个适合业务系统技术栈的脚手架，那么今天就来介绍如何快速搭建一个适合我们的万能轻量级的脚手架，包含前后端的开发，服务监控，接口管理等等。技术栈采用用Springboot 3.4.1 + druid + spring task + mybatis + mybatis generator + swagger(新版swaggerUI) + mysql + SpringbootAdmin + vue2 + element.

一、整体技术架构图

在这里插入图片描述

二、准备工作

1. 插件和软件准备

1. idea <开发工具>
2. idea 插件 - maven dependency helper
3. idea 插件 - database <非社区版自带> || navcat for mysql || workbench
4. idea 插件 - vuejs <高版本自带>
5. jdk 17 +
6. chrome
7. maven <可自己安装或使用idea自带maven工具>

2.通过官方工具快速创建脚手架

2.1 快速创建项目工具

2.1.1 打开 https://start.spring.io/ 网站

在这里插入图片描述
项目的基础信息填写就不多说了(groupId/artifatId/name)，打包方式选jar，java版本选17。需要额外的安装包的话，就自己在右侧添加即可，选择完成之后，点击GENERATE生成项目。

在这里插入图片描述

---.mvn       maven wrapper
---src        程序目录
.gitignore    git 忽略文件
mvnw          maven wrapper执行器
pom.xml       maven配置

2.1.2 使用idea 打开此目录

打开setting -> maven -> user setting file

在这里插入图片描述

配置maven, 将下面代码保存为setting-alibaba.xml 然后idea maven配置设置为此文件。

Global Level. This settings.xml file provides configuration for all Maven|                 users on a machine (assuming they're all using the same Maven|                 installation). It's normally provided in |                 ${maven.home}/conf/settings.xml.||                 NOTE: This location can be overridden with the CLI option:||                 -gs /path/to/global/settings.xml|| The sections in this sample file are intended to give you a running start at| getting the most out of your Maven installation.

The mirror site will be the preferred | server for that repository.|--><mirrors><!-- mirror| Specifies a repository mirror site to use instead of a given repository. The repository that| this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used| for inheritance and direct lookup purposes, and must be unique across the set of mirrors.|<mirror><id>mirrorId</id><mirrorOf>repositoryId</mirrorOf><name>Human Readable Name for this Mirror.</name><url>http://my.repository.com/repo/path</url></mirror>-->

Profiles provided in the settings.xml are intended to provide local machine-| specific paths and repository locations which allow the build to work in the local environment.|| For example, if you have an integration testing plugin - like cactus - that needs to know where| your Tomcat instance is installed, you can provide a variable here such that the variable is | dereferenced during the build process to configure the cactus plugin.|| As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles| section of this document (settings.xml) - will be discussed later. Another way essentially| relies on the detection of a system property, either matching a particular value for the property,| or merely testing its existence. Profiles can also be activated by JDK version prefix, where a | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.| Finally, the list of active profiles can be specified directly from the command line.|| NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact|       repositories, plugin repositories, and free-form properties to be used as configuration|       variables for plugins in the POM.||--><profiles> <profile><id>development</id><repositories><repository><id>central</id><url>http://central</url><releases><enabled>true</enabled><updatePolicy>always</updatePolicy></releases><snapshots><enabled>true</enabled><updatePolicy>always</updatePolicy></snapshots></repository></repositories><pluginRepositories><pluginRepository><id>central</id><url>http://central</url><releases><enabled>true</enabled><updatePolicy>always</updatePolicy></releases><snapshots><enabled>true</enabled><updatePolicy>always</updatePolicy></snapshots></pluginRepository></pluginRepositories></profile><profile><!--this profile will allow snapshots to be searched when activated--><id>public-snapshots</id><repositories><repository><id>public-snapshots</id><url>http://public-snapshots</url><releases><enabled>false</enabled></releases><snapshots><enabled>true</enabled><updatePolicy>always</updatePolicy></snapshots></repository></repositories><pluginRepositories><pluginRepository><id>public-snapshots</id><url>http://public-snapshots</url><releases><enabled>false</enabled></releases><snapshots><enabled>true</enabled><updatePolicy>always</updatePolicy></snapshots></pluginRepository></pluginRepositories></profile></profiles><activeProfiles><activeProfile>development</activeProfile><activeProfile>public-snapshots</activeProfile></activeProfiles>
</settings>

刷新maven引入依赖包…

2.2 补齐依赖

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

2.3 启动服务

这个是后没有配置MySQL连接，服务是起不来的，所以要加个注解先忽略DB的autoconfig。

package com.example.demo;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.sql.init.dependency.DatabaseInitializationDependencyConfigurer;@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class}
)
public class DemoApplication {public static void main(String[] args) {SpringApplication.run(DemoApplication.class, args);}}

启动成功！！！

三、写第一个接口

创建web/TestController
在这里插入图片描述
写以下代码：

package com.example.demo.web;import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
@RequestMapping("/test")
public class TestController {@GetMapping("")public String test(){return "test";}}
