如何在Hikaricp中限制初始池大小? [英] How to restrict initial pool size in hikaricp?

问题描述

我曾经有一个tomcat连接池配置，它限制了初始池的大小:spring.datasource.tomcat.initial-size=2

I used to have a tomcat connection pool configuration restricting the initial pool size: spring.datasource.tomcat.initial-size=2

现在切换到hikaricp:限制最初启动的连接的等效条件是什么?

Now switching to hikaricp: what is the equivalent to restrict the initially started connections?

旁注:spring.datasource.hikari.minimumIdle不会阻止在启动时初始化10个连接.

Sidenote: spring.datasource.hikari.minimumIdle does not prevent initializing 10 connections at startup.

推荐答案

我刚刚发现它与我配置多个数据源有关.

I just found out it had to do with my configuration of multiple datasources.

通常，属性spring.datasource.hikari.minimum-idle=2自动正确限制启动池的大小！

In general, the property spring.datasource.hikari.minimum-idle=2 automatically restricts the startup pool size correctly!

但是，如果有多个数据源，则缺少配置属性，如下所示:

But if having multiple data sources, there was a configuration property missing, as follows:

    @Bean
    @ConfigurationProperties("spring.datasource.secondary.hikari")
    public DataSource secondatyDataSource() {
        return ...
    }

在我刚拥有"spring.datasource.secondary"之前，并没有考虑到我的财产"spring.datasource.secondary.hikari.*".

Before I just had "spring.datasource.secondary", and there by my property "spring.datasource.secondary.hikari.*" was not taken into account.

这可能是错误的记载 https://docs.spring. io/spring-boot/docs/current/reference/html/howto-data-access.html

This is probably wrong documented in https://docs.spring.io/spring-boot/docs/current/reference/html/howto-data-access.html
