基於springboot的后端服務開發腳手架

背景

我們的系統基本都是前后端分離架構，后端服務主要框架是基於java的spring boot，為了快速的構建新項目，將平時做后端的東西抽出一個開發腳手架。

技術棧

1. java 8
2. spring-boot 2.2.7.RELEASE
3. swagger 2.9.2
4. guava 29.0-jre
5. mybait.spring 1.3.2
6. HikariCP 3.2.0
7. xxl-job 2.1.0
8. lombok 1.18.0
9. Jedis 3.2.0
10. Elasticsearch 7
11. zookeeper client 4.3.0

項目

名稱：spring-boot-seed

seed-client：常用的組件client

seed-common：通用類和util

seed-task：集成xxl-job做定時任務

seed-web：web后端服務，數據庫mysql，使用spring mybatis操作數據庫

小記錄：

Springboot中bean的“構造”和“析構”順序：

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
