Hikaricp简单使用

Hikaricp 替换现有的数据库连接池也是很方便的没有时间去测试现贴出简单的配置
如果使用spring，只需要简单的替换
<bean id="hikariDataSource"
class="com.zaxxer.hikari.HikariDataSource" destroy-method="shutdown">
<constructor-arg>
<bean class="com.zaxxer.hikari.HikariConfig">
<property name="driverClassName" value="${hikaricp.jdbc.driverClassName}"/>
<property name="jdbcUrl" value="${hikaricp.url}"/>
<property name="username" value="${hikaricp.username}"/>
<property name="password" value="${hikaricp.password}"/>
<property name="connectionTestQuery" value="${hikaricp.connectionTestQuery}"/>
<property name="connectionTimeout" value="${hikaricp.connectionTimeout}"/>
<property name="idleTimeout" value="${hikaricp.idleTimeout}"/>
<property name="maxLifetime" value="${hikaricp.maxLifetime}"/>
<property name="maximumPoolSize" value="${hikaricp.maximumPoolSize}"/>
<property name="minimumIdle" value="${hikaricp.minimumIdle}"/>
</bean>
</constructor-arg>
</bean>

引入的properties文件：
#HikariDataSource config
hikaricp.jdbc.driverClassName=com.mysql.jdbc.Driver
hikaricp.url= jdbc:mysql://127.0.0.1:3306/dcserver38?useUnicode=true&characterEncoding=UTF-8
hikaricp.quratz_jdbc.url=jdbc:mysql://127.0.0.1:3306/quartz?useUnicode=true&characterEncoding=UTF-8
hikaricp.username=root
hikaricp.password=123456
hikaricp.connectionTestQuery= SELECT 1
hikaricp.connectionTimeout = 30000
#This property controls the maximum amount of time (in milliseconds)\
# that a connection is allowed to sit idle in the pool. Whether a connection is retired \
# as idle or not is subject to a maximum variation of +30 seconds, and average variation of +15 seconds.\
# A connection will never be retired as idle before this timeout. A value of 0 means that idle connections \
# are never removed from the pool. Default: 600000 (10 minutes)
hikaricp.idleTimeout = 600000
#This property controls the maximum lifetime of a connection in the pool. When a connection reaches this timeout, \
# even if recently used, it will be retired from the pool. An in-use connection will never be retired, \
# only when it is idle will it be removed. We strongly recommend setting this value, and using something \
# reasonable like 30 minutes or 1 hour. A value of 0 indicates no maximum lifetime (infinite lifetime), s\
# ubject of course to the idleTimeout setting. Default: 1800000 (30 minutes)
hikaricp.maxLifetime = 1800000
#池连接数量
hikaricp.maximumPoolSize =100
hikaricp.minimumIdle =100
