问题 We migrated from oracle c12 to c19.

问题 I'm trying to develop a Java application that connects to an Oracle database and executes a function. If I run the application in Eclipse it works, but when I try to run the .jar built with Maven Shade an error is thrown "Error encountered: java.sql.SQLException: No suitable driver found". Steps Execute "mvn clean install -U" Execute .jar with "java -jar example-1.0-SNAPSHOT.jar" I can see that the Maven throws some WARNINGS about overlapping resources, could this be the reason? [WARNING]

问题 I am using oracle DB with below column START_TIME INTERVAL DAY(0) TO SECOND(0) I am using jdbc template in java code to access this value using the row mapper and getString() method like below: (I am running a basic select query to fetch values from DB) String startTime = rs.getString("START_TIME"); and the value I get is in this format System.out.println(startTime); // 0 9:30:0.0 I am not able to format this value in the HH:MM format string. I do not need the seconds as I am ignoring that
