若是计划是第一种的话 改为第二种就能够

mysql的局地配置已经增多去了,还是特别,第二数据源下边包车型客车配备有标题?
附:这是互连网另一种说法的代码,加上如故没起功效。 求解
#证实连接的卓有成效

    用mybatis2.3.5兑现做应用时,程序中报以下错误: 

Cause: org.apache.ibatis.transaction.TransactionException: Error configuring AutoCommit. Your driver may not support getAutoCommit() or setAutoCommit(). Requested setting: false. Cause: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 57,704,088 milliseconds ago.

org.apache.ibatis.exceptions.PersistenceException:

乐百家数据库 1

报错日志:

    用hibernate的话, 加如下属性:  

mysql服务端会暗中同意检查种种连接connection,一旦开采connection被弃置8钟头(wait_timeout),便会被断开。那大家能够在三番五次字符串中进入autoReconnect=true,同期布署下mybatis,一段时间又默许实践下简单的询问,声明本身那个三番五次还活着,具体安顿如下:
2015-03-26 09:40:25.956 ERROR GroupPrivController,119 -

乐百家数据库 2

数据源配置:
乐百家数据库 3

    若是延续闲置8小时 (mysql的wait_timeout参数私下认可时间), mysql就能够活动断开连接, 得刷新应用才行.  

The error may exist in mybatis/hiveDb.xml

spring.datasource.time-between-eviction-runs-millis=300000

 

The error may involve com.weibo.hamza.core.dao.DbDao.findByOwnerId

#连接池空闲连接的实用时间 ,设置30分钟

    不用hibernate的话, connection url加参数:
