Grails maxRows/queryTimeout警告
我似乎在Grails2.2.4应用程序中随机得到下面的警告。它看起来没有引起任何问题,但它仍然令人担忧 我试图通过修改我的Grails maxRows/queryTimeout警告,grails,Grails,我似乎在Grails2.2.4应用程序中随机得到下面的警告。它看起来没有引起任何问题,但它仍然令人担忧 我试图通过修改我的datasource.groovy文件中的数据源属性来防止此警告: dataSource { pooled = true properties { maxWait = 10000 // 10 seconds minEvictableIdleTimeMillis = 1000 * 60 * 30 // 30 minutes
datasource.groovy
文件中的数据源属性来防止此警告:
dataSource {
pooled = true
properties {
maxWait = 10000 // 10 seconds
minEvictableIdleTimeMillis = 1000 * 60 * 30 // 30 minutes
numTestsPerEvictionRun = 3
testOnBorrow = true
testOnReturn = false
testWhileIdle = false
timeBetweenEvictionRunsMillis = 1000 * 60 * 30 // 30 minutes
validationQuery = "SELECT 1"
}
}
def init = { servletContext ->
def ctx = Holders.getApplicationContext()
def dataSource = ctx.dataSourceUnproxied
println "configuring database connection pool"
dataSource.setMinEvictableIdleTimeMillis(1000 * 60 * 30)
dataSource.setTimeBetweenEvictionRunsMillis(1000 * 60 * 30)
dataSource.setNumTestsPerEvictionRun(3)
dataSource.setTestOnBorrow(true)
dataSource.setTestWhileIdle(false)
dataSource.setTestOnReturn(false)
dataSource.setValidationQuery("SELECT 1")
}
当这不起作用时,我尝试在我的BootStrap.groovy
文件中设置属性:
dataSource {
pooled = true
properties {
maxWait = 10000 // 10 seconds
minEvictableIdleTimeMillis = 1000 * 60 * 30 // 30 minutes
numTestsPerEvictionRun = 3
testOnBorrow = true
testOnReturn = false
testWhileIdle = false
timeBetweenEvictionRunsMillis = 1000 * 60 * 30 // 30 minutes
validationQuery = "SELECT 1"
}
}
def init = { servletContext ->
def ctx = Holders.getApplicationContext()
def dataSource = ctx.dataSourceUnproxied
println "configuring database connection pool"
dataSource.setMinEvictableIdleTimeMillis(1000 * 60 * 30)
dataSource.setTimeBetweenEvictionRunsMillis(1000 * 60 * 30)
dataSource.setNumTestsPerEvictionRun(3)
dataSource.setTestOnBorrow(true)
dataSource.setTestWhileIdle(false)
dataSource.setTestOnReturn(false)
dataSource.setValidationQuery("SELECT 1")
}
这两种尝试都不能阻止警告。post的作者说他已经成功地直接在tomcat配置中设置了属性,但是我需要一个更通用的解决方案,它可以在命令行和其他服务器中工作

在与MySQL数据库的连接超时后,我也会看到这个异常。我使用中的建议作为指导更新了数据源配置,并且我还没有看到关闭连接的任何异常 以下是我当前的设置:
properties {
initialSize=5
maxActive=50
minIdle=5
maxIdle=25
maxWait = 10000
maxAge = 10 * 60000
timeBetweenEvictionRunsMillis = 5000
minEvictableIdleTimeMillis = 60000
validationQuery = "SELECT 1"
validationQueryTimeout = 3
validationInterval = 15000
testOnBorrow = true
testWhileIdle = true
testOnReturn = false
jdbcInterceptors = "ConnectionState;StatementCache(max=200)"
defaultTransactionIsolation = java.sql.Connection.TRANSACTION_READ_COMMITTED
}
