Couldn't get connection because we are at maximum connection count (150/150) and there are none 异常解决

系统运行一段时间后发现出现这样的异常:

Couldn't get connection because we are at maximum connection count (150/150) and there are none available

解决方案：

1、修改连接池的最大的连接数：

<maximum-connection-count>1000</maximum-connection-count>

2、更改hibernate.connection.release_mode配置的模式为：after_transaction

Hibernate 的连接释放模式：hibernate.connection.release_mode 有三个选择：after_statement/after_transaction/on_close，默认的是on_close所以，这里要改成after_transaction

<prop key="hibernate.connection.release_mode">after_transaction</prop>
