日志错误：
Service Broker needs to access the master key in the database ‘BRM_TEST‘. Error code:32. The master key has to exist and the service master key encryption is required.

原因：
SqlDependency在清理服务，队列，存储过程时需要一个转换，这个转换需要数据库的master key去存储产生的会话key,虽没多大影响，但会产生错误日志。解决方法是创建一个key给他用。
CREATE MASTER KEY ENCRYPTION BY PASSWORD = ‘23987hxJ#KL95234nl0zBe‘;
