The Error

Field error in object 'flightPlanning' on field 'arrivalTime': rejected value [15:45]; codes [typeMismatch.flightPlanning.arrivalTime,typeMismatch.arrivalTime,typeMismatch.java.sql.Time,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [flightPlanning.arrivalTime,arrivalTime]; arguments []; default message [arrivalTime]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'java.sql.Time' for property 'arrivalTime'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [@javax.persistence.Column java.sql.Time] for value '15:45'; nested exception is java.lang.IllegalArgumentException] Field error in object 'flightPlanning' on field 'depTime': rejected value [04:56]; codes [typeMismatch.flightPlanning.depTime,typeMismatch.depTime,typeMismatch.java.sql.Time,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [flightPlanning.depTime,depTime]; arguments []; default message [depTime]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'java.sql.Time' for property 'depTime'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type

Here the form in thymeleaf


            
                
                    
                        Departure Date
                        Source
                        Destination
                        Departure Time
                        Arrival Time
                        Offset
                        Seat Capacity
                        Fare (â‚¹)

How to format the *{depTime} and *{arrivalTime} in such a way that the java.sql.Time variables accept these values. I am new to spring, whether this is to be done in thymeleaf itself or in java controller. Is there any way it can be done using spring controller or thymeleaf or JS.

The problem is from trying to store Time in SQL. It looks like your JPA implementation doesn't like sql.Time (I'm not sure any JPA implementations handle it at all anyway) Try LocalDateTime and it should persist properly.

Edit: looks like sql.Time is fine as well (my apologies)

This seems to be more complicated than I thought. It looks like you are trying to input String data from a form and send it to your @PostMapping. This is why it's complaining about String to LocalDateTime conversion. (it wont auto convert like simpler Object types). You need to find a way to parse the String data into a LocalDateTime.

A Simpler workaround may be to have a pre-existing collection of FlightPlanning that you can instead select with the form.

Annotate the time and date parameters as shown below, I had experienced the same problem earlier

@Column(name = "dep_time")
@DateTimeFormat(iso = DateTimeFormat.ISO.TIME)
private java.time.LocalTime dep_time;
@Column(name = "arrival_time")
@DateTimeFormat(iso = DateTimeFormat.ISO.TIME)
private java.time.LocalTime arrivalTime;
@Column(name = "departure_Date")
@DateTimeFormat(pattern = "yyyy-MM-dd")
private java.time.LocalDate departureDate;
