spring-boot - HikariCP 中的 initializationFailTimeout 属性

Question

来自 Github:

Any positive number is taken to be the number of milliseconds toattempt to acquire an initial connection; the application thread willbe blocked during this period. Default: 1

我理解如果在 1 秒内未获得连接则使用默认值时将抛出错误。我计划将该值设置为 1000 毫秒，因为有时我会收到错误

"hikaripool$poolinitializationexception"

启动 spring boot Java 8 应用时。这是正确的做法吗？

Answer 1

不完全是等待连接 connectTimeout + initializationFailTimeout ，来自 github :

This timeout is applied after the connectionTimeout period

默认是半分钟

Default: 30000 (30 seconds)

您可以输入 -1 值以允许池启动而不会失败

A value less than zero will bypass any initial connection attempt, and the pool will start immediately while trying to obtain connections in the background
