Use gradle on SpringBoot 1.5.3 introduced hikariCP
hikari from the Japanese term, "light" means, known as "the fastest in the history database connection pool", also springboot2.0 latest version of the default connection pool. But springboot1.5.x project can also be used.
springboot1.5.x default database connection pool is tomcat-jdbc connection pool, you want to migrate to modify hikari connection pool only a few steps to configure on:
build.gradle file
1, first remove the default tomcat connnection pool from dependence
compile("org.springframework.boot:spring-boot-starter-data-jpa:1.5.3.RELEASE"){
exclude group: 'org.apache.tomcat', module: 'tomcat-jdbc'
}
2, dependent on the introduction of
compile group: 'com.zaxxer', name: 'HikariCP', version: '3.4.1'
3, application.properties connection pool configuration file properties
spring.datasource.type=com.zaxxer.hikari.HikariDataSource spring.datasource.hikari.pool-name=SomeThingHikariCP spring.datasource.hikari.minimum-idle=5 spring.datasource.hikari.idle-timeout=600000 spring.datasource.hikari.maximum-pool-size=20 spring.datasource.hikari.auto-commit=true spring.datasource.hikari.max-lifetime=1800000 spring.datasource.hikari.connection-timeout=6000 spring.datasource.hikari.connection-test-query=SELECT 1 FROM DUAL
The original spring.datasource.tomcat.xxxx need commented out.
Restart the project, the console will see the following log
...
