I'm trying to set up HikariCP in my Spring Boot (1.2.0.M1) app so I can test using it in place of Tomcat DBCP. I'd like to configure the connection pool in my application.properties file like I was doing with Tomcat, but I can't figure out how I should be doing it. All examples I've found show either JavaConfig style, or using a separate HikariCP properties file. Can someone help me figure out the property names to configure it in application.properties? I'd like to also switch from using the driverClassName approach to the DataSourceClassName approach since it looks cleaner and is recommended. Is this also possible in my application.properties file(s)?
Here's what I had for Tomcat DBCP (just some basic config, not fully flushed out)
spring.datasource.validation-query=SELECT 1
spring.datasource.max-active=10
spring.datasource.max-idle=8
spring.datasource.min-idle=8
spring.datasource.initial-size=5
spring.datasource.test-on-borrow=true
spring.datasource.test-on-return=true
And I'm currently using driverClassName and jdbc url to set up the connection:
spring.datasource.url=jdbc:mysql://localhost:3306/myDb
spring.datasource.driverClassName=com.mysql.jdbc.Driver
@Configuration
@ConfigurationProperties(prefix = "params.datasource")
public class JpaConfig extends HikariConfig {
@Bean
public DataSource dataSource() throws SQLException {
return new HikariDataSource(this);
}
}
application.yml
params:
datasource:
driverClassName: com.mysql.jdbc.Driver
jdbcUrl: jdbc:mysql://localhost:3306/myDb
username: login
password: password
maximumPoolSize: 5
UPDATED! Since version Spring Boot 1.3.0 :
application.yml
spring:
datasource:
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:h2:mem:TEST
driver-class-name: org.h2.Driver
username: username
password: password
hikari:
idle-timeout: 10000
UPDATED! Since version Spring Boot 2.0.0 :
The default connection pool has changed from Tomcat to Hikari :)
