SpringBoot效能優化之HikariCP連線池
阿新 • • 發佈：2020-02-09
以前一直使用阿里Druid資料庫連線池，這段時間聽說有個號稱速度最快、程式碼最簡的後起之秀——HikariCP，於是動手實踐一下
1.依賴如下：

# 檔案上傳配置
spring:
## 資料庫配置
datasource:
type: com.zaxxer.hikari.HikariDataSource
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://127.0.0.1:3306/website?serverTimezone=GMT%2B8&useUnicode=true&characterEncoding=utf8&allowMultiQueries=true

## Hikari 連線池配置 ------ 詳細配置請訪問：https://github.com/brettwooldridge/HikariCP
hikari:
## 最小空閒連線數量
minimum-idle: 10
## 空閒連線存活最大時間，預設600000（10分鐘）
idle-timeout: 18000
## 連線池最大連線數，預設是10
maximum-pool-size: 1000
## 此屬性控制從池返回的連線的預設自動提交行為,預設值：true
auto-commit: true
## 連線池母子
pool-name: OfficialWebsiteHikariCP
## 此屬性控制池中連線的最長生命週期，值0表示無限生命週期，預設1800000即30分鐘
max-lifetime: 1800000
## 資料庫連線超時時間,預設30秒，即30000
connection-timeout: 300000
connection-test-query: SELECT 1
jpa:
show-sql: true
open-in-view: true
jackson:
default-property-inclusion: non_null
logging:
config: classpath:logback.xml3.啟動服務，看日誌都是INFO，沒有ERROR，好像沒報啥錯，但是啟動失敗了

INFO [2020-02-08 21:08:32,202][] com.zaxxer.hikari.HikariDataSource:352 - WebsiteHikariCP - Shutdown completed. 調配置調了半天，換回原來的Druid連線池也是不行，再看看日誌，發現倒數第四行：Closing JPA EntityManagerFactory for persistence unit 'default'
發現問題了，這個問題似曾熟悉，好久之前遇到過，而且不是ERROR報出來的，太不明顯了（為自己的粗心找個理由，哈哈），再回去看看依賴，發現少了一個web依賴：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
4.把這個依賴加上就行，問題解決，成功啟動

5.效能測試
有很多朋友已經親測過了，這裡我分享一個地址，大家進去比對一下各項效能，綜合自己業務以及架構需要，採用合適的連線池即可
