The embedded tomcat server fails to start when running my spring boot application. I have just added the required dependencies in pom.xml and have created a simple java POJO class. The application properties have been set with required jdbc configurations as required by oracle database along with the Hibernate Dialect information.
The spring boot tries to start the server and immediately shuts it down. There are no errors noticed in the console.
I have already checked and verified that the jdbc url, username, password are right as If I pass them incorrectly, i notice a different error.
application.properties file
#Properties for Oracle connection using Java config
oracle.username=XXXX
oracle.password=XXXX
oracle.url=jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=host.oracle.com)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=host.oracle.com)))
