Mysql报com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create conne
1、一开始我认为这个问题是因为在创建了了connection后使用完未关闭connection而又创立新的connection导致的,因此要在用完connection之后使用.close()方法将connection关闭。 2、但是这样是不够的,还是要看cause by什么<em>错</em>误才可以解决,一开始报的<em>错</em>误是Caused by: android.os.NetworkOnMainThreadExcep...
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Too many connections
https://blog.csdn.net/zhou920786312/article/details/78395588 产生这种问题的原因是: 连接数超过了 MySQL 设置的值,与 max_connections 和 wait_timeout 都有关系。wait_timeout 的值越大,连接的空闲等待就越长,这样就会造成当前连接数越大。 解决思路: 修改MySQL配置文件/etc/m...

MySQL出现MySQLNonTransientConnectionException: No operations allowed after statement closed异常的解决办法
出现异常的原因:  Mysql在5以后针对超长时间DB连接做了一个处理,Mysql服务器默认的“wait_timeout”是8小时,也就是说一个connection空闲超过8个小时,Mysql将自动断开该connection。所以使用连接池的时候虽然连接对象还在但是链接数据库的时候会一直报这个异常。解决办法:  进入MySQL查看设置的时间,show global variables like '...
