### Error querying database. Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory ([jcc][t4][2043][11550][3.57.82] 异常 java.net.ConnectException：打开端口 60,000 上服务器 /20.78.86.1 的套接字时出错，消息为：Connection timed out: connect。 ERRORCODE=-4499, SQLSTATE=08001)
我重新保存了下jdbc.properties重新编译再启动错误解决，初步猜测是新项目导入带进了原来编译好的文件导致报错
