我使用Spring Boot + MyBatis + druid1.0.23讀取表中的Long RAW字段時出現異常，然后我又使用Spring里的SingleConnectionDataSource能正常讀取，日志記錄的異常信息如下：

org.springframework.jdbc.UncategorizedSQLException: Error attempting to get column 'ZP' from result set. Cause: java.sql.SQLException: 流已被關閉

; uncategorized SQLException for SQL []; SQL state [99999]; error code [17027]; 流已被關閉; nested exception is java.sql.SQLException: 流已被關閉
