com.alibaba.druid.pool.GetConnectionTimeoutException: wait millis 3000, active 16,maxActive 16
Could not open JDBC Connection for transaction; nested exception is com.alibaba.druid.pool.GetConnectionTimeoutException: wait millis 3000, active 16, maxActive 16"这个异常可能是因为druid连接池泄漏产生的异常。连接超时,active和maxActive相等,不能够创建新的连接,如果很长时间还获取不到,很有可能是连接池泄漏
