Spring Boot 2 disable Autocommit Hikari with multiple datasources

问题

I am attempting to turn of auto-commit on Hikari with multiple data sources, but I'm not having any luck. I'm using Spring Boot 2 (2.0.3.RELEASE). Here is my config:

application.properties

spring.datasource.primary.driver=com.mysql.cj.jdbc.Driver
spring.datasource.primary.url=jdbc:mysql://localhost:3306/spark?autoReconnect=true
spring.datasource.primary.username=xxxx
spring.datasource.primary.password=xxxx
spring.datasource.primary.max-active=100
spring.datasource.primary.max-idle=5
spring.datasource.primary.min-idle=1
spring.datasource.primary.test-while-idle=true
spring.datasource.primary.test-on-borrow=true
spring.datasource.primary.validation-query=SELECT 1
spring.datasource.primary.time-between-eviction-runs-millis=5000
spring.datasource.primary.min-evictable-idle-time-millis=60000


spring.datasource.ucm.driver=com.mysql.cj.jdbc.Driver
spring.datasource.ucm.url=jdbc:mysql://localhost:3306/usercentral?autoReconnect=true
spring.datasource.ucm.username=xxx
spring.datasource.ucm.password=xxx
spring.datasource.ucm.max-active=100
spring.datasource.ucm.test-while-idle=true
spring.datasource.ucm.test-on-borrow=true
spring.datasource.ucm.validation-query=SELECT 1
spring.datasource.ucm.time-between-eviction-runs-millis=5000
spring.datasource.ucm.min-evictable-idle-time-millis=60000
spring.datasource.ucm.hikari.auto-commit=false  # <- Not working

Here's my configuration class where the data sources are setup

@Primary
@Bean
@ConfigurationProperties("spring.datasource.primary")
public DataSourceProperties primaryDataSourceProperties() {
    return new DataSourceProperties();
}

@Bean
@Primary
@ConfigurationProperties("spring.datasource.primary")
public DataSource primaryDataSource() {
    return primaryDataSourceProperties().initializeDataSourceBuilder().build();
}

@Bean
@ConfigurationProperties("spring.datasource.ucm")
public DataSourceProperties ucmDataSourceProperties() {
    return new DataSourceProperties();
}

@Bean(name="ucmDataSource")
@ConfigurationProperties("spring.datasource.ucm")
public DataSource ucmDataSource() {
    return ucmDataSourceProperties().initializeDataSourceBuilder().build();
}

Here is what is being output when the pool is created:

-2018-08-23 15:48:22.845 -DEBUG 21455 --- [nio-8081-exec-1] com.zaxxer.hikari.HikariConfig           : 1151 : allowPoolSuspension.............false
-2018-08-23 15:48:22.846 -DEBUG 21455 --- [nio-8081-exec-1] com.zaxxer.hikari.HikariConfig           : 1151 : autoCommit......................true
-2018-08-23 15:48:22.846 -DEBUG 21455 --- [nio-8081-exec-1] com.zaxxer.hikari.HikariConfig           : 1151 : catalog.........................none
-2018-08-23 15:48:22.846 -DEBUG 21455 --- [nio-8081-exec-1] com.zaxxer.hikari.HikariConfig           : 1151 : connectionInitSql...............none

How do I turn off auto-commit on this connection pool?

Thanks!

回答1:

I am using Spring Boot 2.0.4.RELEASE, and faced the same problem. Spent hours with related posts showing non-working properties...

Removing .hikari worked for me.

spring.datasource.ucm.autocommit=false

回答2:

Alternative solution to your problem, configure default-auto-commit property as false. It should also work.

spring.datasource.ucm.default-auto-commit=false

Spring Boot Ref 1

default.auto-commit

回答3:

Make false default-auto-commit should work.

spring.datasource.ucm.default-auto-commit=false

I know that this is very late but this issue exploded my brain for ~2 days and this post is at the top of google search so I will post here the solution for others.

It's actually quite simple, just that I missed it in the docs here https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-two-datasources

log story short make sure that you add .type(HikariDataSource.class) before you build your class.

Also if you use jhipster you should also point your config to the hikari part like this @ConfigurationProperties("spring.datasource.other.hikari")
