Grails MySQL MaxPoolSize

不幸的是,如果您想获得对数据源Springbean的更多控制,您将需要为自己配置该数据源Springbean。这可以通过在“grails-app/conf/spring/resources.groovy”中定义bean来实现

beans = {

   dataSource(org.apache.commons.dbcp.BasicDataSource) {
      driverClassName = "com.mysql.jdbc.Driver"
      username = "someuser"
      password = "s3cret"
      initialSize = 15
      maxActive = 50
      maxIdle = 15
   }

}

可能它还可以覆盖默认grails DataSource.groovy配置的池大小属性,比如利用PropertyOverrideConfiguler(在Config.groovy中):

beans = {
   dataSource.initialSize = 15
   dataSource.maxActive = 50
   dataSource.maxIdle = 15
}

dataSource {
    pooled = true
    dbCreate = "update"
    url = "jdbc:mysql://localhost/yourDB"
    driverClassName = "com.mysql.jdbc.Driver"
    username = "yourUser"
    password = "yourPassword"
    properties {
        maxActive = 50
        maxIdle = 25
        minIdle = 5
        initialSize = 5
        minEvictableIdleTimeMillis = 60000
        timeBetweenEvictionRunsMillis = 60000
        maxWait = 10000     
    }   
}
