[Solved] SpringBoot Integrating Oracle reports errors: ORA-12504, TNS:listener was not given the SID in CONNECT_DATA

Obviously, an error is reported here, saying that Sid cannot be obtained. Obviously, the path is wrong. Check whether the path is completely written?

The error is as follows

java.sql.SQLException: Listener refused the connection with the following error:
ORA-12504, TNS:listener was not given the SID in CONNECT_DATA
