遇到错误Check the judgetypet-InlineParameterMap.

在tomcat的catalin.out 中遇到以下错误

以上的judgetypet为其中一个方法的id值

--- The error occurred in com/unisk/timertask/dao/TimerTaskDao.xml.  
--- The error occurred while applying a parameter map.  
--- Check the judgetypet-InlineParameterMap.  
--- Check the statement (query failed).  
--- Cause: com.mysql.jdbc.CommunicationsException: The last communications with the server was 7200 seconds ago, which  is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

在ibatis的mapper.xml中的sql语句结尾的分号删掉以后就好了

其实还有另一种解决方案 参照  https://blog.csdn.net/chinesesword/article/details/51917496

让mysql驱动开启批量执行sql的开关。

怎么开启呢？在拼装mysql链接的url时，为其加上allowMultiQueries参数，设置为true，如下：

jdbc.jdbcUrl=jdbc:mysql://127.0.0.1:3306/database?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true
