我有一个生产中的应用程序，最近有一个MySQL超时，所以我试图添加额外的参数到数据源，以防止这种情况。在1.3.7 documentation中，它显示我可以像这样添加属性值：
properties {
maxActive = 50
maxIdle = 25
minIdle = 5
initialSize = 5
minEvictableIdleTimeMillis = 60000
timeBetweenEvictionRunsMillis = 60000
maxWait = 10000
validationQuery = "/* ping */"
}
但是，当我将其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？感谢。

我在本地测试了这个，所以我将属性放在development块中。但是，我没有添加pooled = true，因为它通常不在此部分中。这导致了错误。一旦我添加了汇集语句，一切正常。
