Grails 数据源异常

Question

我有一个生产中的应用程序最近发生了 MySQL 超时，因此我尝试向数据源添加额外的参数来防止这种情况发生。在 1.3.7 documentation它表明我可以添加一个属性值，如下所示:

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

但是，当我将其添加到我的开发数据源时，出现以下错误:

 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.

可能是什么问题？谢谢。

Answer 1

我在本地测试了这个，所以我将属性放在我的development block 中。但是，我没有添加 pooled = true 因为它通常不在本节中。这是导致错误的原因。添加池语句后，一切正常。
