使用druid连接池,出现以下错误

org.springframework.jdbc.UncategorizedSQLException:

Error updating database. Cause: com.mysql.jdbc.exceptions.MySQLTimeoutException: Statement cancelled due to timeout or client request

The error may involve lotteryMapper.insertMultiChanceApp-Inline

The error occurred while setting parameters

SQL: insert into lottery (platform,activity,activity_id,openid,type,status,get_time) values (?,?,?, ?,?,?,?) , (?,?,?, ?,?,?,?) , (?,?,?, ?,?,?,?) , (?,?,?, ?,?,?,?)

Cause: com.mysql.jdbc.exceptions.MySQLTimeoutException: Statement cancelled due to timeout or client request

; uncategorized SQLException for SQL []; SQL state [null]; error code [0]; Statement cancelled due to timeout or client request; nested exception is com.mysql.jdbc.exceptions.MySQLTimeoutException: Statement cancelled due to timeout or client request

我的druid的配置是

    <property name="validationQuery" value="SELECT 'x'" /><!-- -->
    <property name="testWhileIdle" value="true" />
    <property name="testOnBorrow" value="false" />
    <property name="testOnReturn" value="false" />

    当表数据量达到2kw时,压测tps为2k,就会报者错误,
    请问怎么去判断问题出在哪里,求大神帮忙,给解决思路!

mysql连接超时，看看是不是查询太复杂，时间不够，或者网络问题

楼主解决了么?我也遇到这个问题,只要sql查询时间超过25秒左右就会出错.
