当经常有发生连接池满获取不到连接时，可以开启druid监控，在连接都正常关闭的应用中，不应该出现下列警告，如下：

要查看活跃的连接堆栈，需要开启下列选项：dyn.spring.datasources[0].removeAbandoned=true dyn.spring.datasources[0].removeAbandonedTimeout=600 dyn.spring.datasources[0].logAbandoned=true
按照druid的文档配置对应的fitler，即可同时监控多数据源，包括在sharding jdbc中的数据源。可参考下列：

这样在发生连接获取不到时就能够找到哪些逻辑没有正常关闭连接。
