Grails數據源異常

Question

我有一個生產中的應用程序，最近有一個MySQL超時，所以我試圖添加額外的參數到數據源來防止這種情況。在1.3.7 documentation它表明我可以添加像這樣一個屬性值：

properties { 
     maxActive = 50 
     maxIdle = 25 
     minIdle = 5 
     initialSize = 5 
     minEvictableIdleTimeMillis = 60000 
     timeBetweenEvictionRunsMillis = 60000 
     maxWait = 10000 
     validationQuery = "/* ping */" 
    } 

然而，當我加入這個我發展數據源我得到以下錯誤：

ERROR Error executing bootstraps: Error creating bean with name 'messageSource': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'transactionManager': Cannot resolve reference to bean 'sessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory': Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource': Cannot resolve reference to bean 'dataSourceUnproxied' while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSourceUnproxied': Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'maxActive' of bean class [org.springframework.jdbc.datasource.DriverManagerDataSource]: Bean property 'maxActive' is not writable or has an invalid setter method.

可能是什麼問題？謝謝。

我在本地測試這個，所以我把屬性放在我的development塊中。但是，我沒有添加pooled = true，因爲它通常不在本節中。這是造成錯誤。一旦我添加了池化聲明，一切正常。
