我在 intellij 上运行 springboot 应用程序时出错。 有人能帮我吗？

Question

Why do I get this error connecting to a remote Oracle Database. I do have access rights and I can access the database through DataGrip。 It causes the application to close again.

WARN  org.apache.tomcat.jdbc.pool.ConnectionPool - Connection has been abandoned PooledConnection[oracle.jdbc.driver.T4CConnection@fe13916]:java.lang.Exception
    at org.apache.tomcat.jdbc.pool.Connection

This is followed by a series of errors.

Finally,I get exception. At the root of caused by, it was

    ... 118 common frames omitted
Caused by: java.sql.SQLException: Closed Resultset
    at oracle.jdbc.driver.InsensitiveScrollableResultSet.findColumn(InsensitiveScrollableResultSet.java:297)
    at oracle.jdbc.driver.GeneratedResultSet.getInt(GeneratedResultSet.java:1350)
    at org.hibernate.tool.schema.extract.internal.InformationExtractorJdbcDatabaseMetaDataImpl.addColumns(InformationExtractorJdbcDatabaseMetaDataImpl.java:577)
    ... 138 common frames omitted

Was it because, the connection was abandoned pre-maturely?

抛出此异常是因为您在 ResultSet 对象之前提前放弃了连接。（不确定！！）无论如何，如果您共享代码，我们可能会更好地提供帮助。
