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，所以我试图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 中，它表明我可以像这样添加一个属性值：

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

但是，当我将它添加到我的开发数据源时，我收到以下错误：

 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

我在本地对此进行了测试，因此我将这些属性放在了我的 development 块中。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。添加池化语句后，一切正常。
