【JAVA】如何快速阅读一个基于maven构建的springboot项目

一、摘要

       在JAVA项目开发过程中，现在比较流行的是springboot机构，特别是在后端开发的项目中，springboot应用的非常普遍。springboot很好将大型的、复杂的项目进行分解，以模块或者服务的表现形式组成项目。那么当我们接手一个陌生的springboot项目时，如何快速阅读项目的架构和功能组成呢。本文做简要介绍。

二、正文

      阅读基于maven构建的springboot项目，我们首先，找到项目里的主pom文件。例如

<?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><groupId>cn.test</groupId><artifactId>test</artifactId><version>${revision}</version></parent><modelVersion>4.0.0</modelVersion><artifactId>test-server</artifactId><packaging>jar</packaging><name>${project.artifactId}</name><description>后端 Server 的主项目，通过引入需要 test-module-xxx 的依赖，从而实现提供 RESTful API 给 test-ui-admin、test-ui-user 等前端项目。本质上来说，它就是个空壳（容器）！</description><url>https://github.com/YunaiV/ruoyi-vue-pro</url><dependencies><dependency><groupId>cn.ctg</groupId><artifactId>test-module-system-biz</artifactId><version>${revision}</version></dependency><dependency><groupId>cn.ctg</groupId><artifactId>test-module-infra-biz</artifactId><version>${revision}</version></dependency><!-- 会员中心。默认注释，保证编译速度 --><dependency><groupId>cn.ctg</groupId><artifactId>test-module-member-biz</artifactId><version>${revision}</version></dependency><!-- 数据报表。默认注释，保证编译速度 --><dependency><groupId>cn.ctg</groupId><artifactId>test-module-report-biz</artifactId><version>${revision}</version></dependency><!-- 工作流。默认注释，保证编译速度 --><dependency><groupId>cn.ctg</groupId><artifactId>test-module-bpm-biz</artifactId><version>${revision}</version></dependency><!-- 支付服务。默认注释，保证编译速度 --><dependency><groupId>cn.ctg</groupId><artifactId>test-module-pay-biz</artifactId><version>${revision}</version></dependency><!-- 微信公众号模块。默认注释，保证编译速度 --><dependency><groupId>cn.ctg</groupId><artifactId>test-module-mp-biz</artifactId><version>${revision}</version></dependency><!-- 商城相关模块。默认注释，保证编译速度--><dependency><groupId>cn.ctg</groupId><artifactId>test-module-promotion-biz</artifactId><version>${revision}</version></dependency><dependency><groupId>cn.ctg</groupId><artifactId>test-module-product-biz</artifactId><version>${revision}</version></dependency><dependency><groupId>cn.ctg</groupId><artifactId>test-module-trade-biz</artifactId><version>${revision}</version></dependency><dependency><groupId>cn.ctg</groupId><artifactId>test-module-statistics-biz</artifactId><version>${revision}</version></dependency><!-- CRM 相关模块。默认注释，保证编译速度 --><dependency><groupId>cn.ctg</groupId><artifactId>test-module-crm-biz</artifactId><version>${revision}</version></dependency><!-- ERP 相关模块。默认注释，保证编译速度 --><dependency><groupId>cn.ctg</groupId><artifactId>test-module-erp-biz</artifactId><version>${revision}</version></dependency><!-- AI 大模型相关模块。默认注释，保证编译速度 -->
<!--        <dependency>-->
<!--            <groupId>cn.ctg</groupId>-->
<!--            <artifactId>test-module-ai-biz</artifactId>-->
<!--            <version>${revision}</version>-->
<!--        </dependency>--><!-- IoT 物联网相关模块。默认注释，保证编译速度 -->
<!--        <dependency>-->
<!--            <groupId>cn.ctg</groupId>-->
<!--            <artifactId>test-module-iot-biz</artifactId>-->
<!--            <version>${revision}</version>-->
<!--        </dependency>--><!-- spring boot 配置所需依赖 --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-configuration-processor</artifactId><optional>true</optional></dependency><!-- 服务保障相关 --><dependency><groupId>cn.ctg</groupId><artifactId>test-spring-boot-starter-protection</artifactId></dependency></dependencies><build><!-- 设置构建的 jar 包名 --><finalName>${project.artifactId}</finalName><plugins><!-- 打包 --><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>${spring.boot.version}</version><executions><execution><goals><goal>repackage</goal> <!-- 将引入的 jar 打入其中 --></goals></execution></executions></plugin></plugins></build></project>

 后端 Server 的主项目，通过引入需要 test-module-xxx 的依赖，
        从而实现提供 RESTful API 给 test-ui-admin、test-ui-user 等前端项目。
        本质上来说，它就是个空壳（容器）！

这一句很好介绍了项目的组件

第二步，我们查看springboot依赖的第三方库和组件，看看都有哪些功能，这是第二步需要看的pom

特别是通过版本信息，我们就知道项目中使用了哪些组件

比如数据库，消息队列，监控，认证，数据库连接池，工具类，日志类等等组件。

第三步，看spring的yml配置文件，看看都配置了什么

比如数据库的链接，redis的连接，定时任务的配置，日志输出的配置等相关内容

第四步、找到项目的启动类，如：

package cn.test.zlt.server;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;/*** 项目的启动类** 如果你碰到启动的问题，请认真阅读 https://doc.iocoder.cn/quick-start/ 文章* 如果你碰到启动的问题，请认真阅读 https://doc.iocoder.cn/quick-start/ 文章* 如果你碰到启动的问题，请认真阅读 https://doc.iocoder.cn/quick-start/ 文章** @author 芋道源码*/
@SuppressWarnings("SpringComponentScan") // 忽略 IDEA 无法识别 ${zlt.info.base-package}
@SpringBootApplication(scanBasePackages = {"${zlt.info.base-package}.server", "${zlt.info.base-package}.module"})
public class ZltServerApplication {public static void main(String[] args) {// 如果你碰到启动的问题，请认真阅读 https://doc.iocoder.cn/quick-start/ 文章// 如果你碰到启动的问题，请认真阅读 https://doc.iocoder.cn/quick-start/ 文章// 如果你碰到启动的问题，请认真阅读 https://doc.iocoder.cn/quick-start/ 文章SpringApplication.run(ZltServerApplication.class, args);
//        new SpringApplicationBuilder(ZltServerApplication.class)
//                .applicationStartup(new BufferingApplicationStartup(20480))
