我有一個(gè) springboot 應(yīng)用程序，它連接到 DB2 數(shù)據(jù)庫(kù)，然后檢索一些數(shù)據(jù)并為其提供 REST 端點(diǎn)。為了促進(jìn)這一點(diǎn)，許可證被添加到應(yīng)用程序的類路徑中，以允許它與 DB2 數(shù)據(jù)庫(kù)進(jìn)行通信。這有效。但是，當(dāng)我在本地構(gòu)建和鏡像并運(yùn)行該鏡像時(shí)，我收到一條錯(cuò)誤，指出許可證不存在。{    "timestamp": 1569854043909,    "status": 500,    "error": "Internal Server Error",    "exception": "org.springframework.jdbc.CannotGetJdbcConnectionException",    "message": "Could not get JDBC Connection; nested exception is com.ibm.db2.jcc.am.SqlSyntaxErrorException: [jcc][t4][10509][13454][4.26.14] Connection to the data server failed.
