基于springboot的后端服务开发脚手架

背景

我们的系统基本都是前后端分离架构，后端服务主要框架是基于java的spring boot，为了快速的构建新项目，将平时做后端的东西抽出一个开发脚手架。

技术栈

• java 21
• spring-boot 3.2.1
• springdoc-openapi 2.3.0
• guava 32
• mybatis.spring 3.0.3
• mysql 8
• HikariCP 3.4.5
• xxl-job 2.1.0
• lombok 1.18.30
• Elasticsearch 7
• redisson 3.23.2
• sa-token 1.37.0

项目名称：spring-boot-seed

• seed-common：通用Util

• seed-engine：基于kafka和disruptor的数据处理服务

• seed-task：集成xxl-job做定时任务

  1. xxl-job
  2. shedlock

• seed-web：web后端服务，数据库mysql，用spring mybatis操作数据库

• swagger: http://localhost:19090/swagger-ui/index.html

小记录：

Springboot中bean的“构造”和“析构”顺序：

1. Bean instance is created
2. Bean properties are set
3. In case bean implements Aware interfaces - those implemented methods are invoked
4. BeanPostProcessor#postProcessBeforeInitialization methods of custom bean post-processors are invoked
5. Initialization callbacks are invoked in the following order:

• 5.1. @PostConstruct method is invoked
• 5.2. InitializingBean#afterPropertiesSet() method is invoked
• 5.3. @Bean#initMethod() method is invoked

Bean is fully initialized now.
6. BeanPostProcessor#postProcessAfterInitialization methods of custom post-processors are invoked
7. Destruction callbacks are invoked in the following order:

• 7.1. @PreDestroy method is invoked
• 7.2. DisposableBean#destroy() method is invoked
• 7.3. @Bean#destroyMethod method is invoked
