Pass java.util.Date using as @Param in query method

Question

I have used java.util.Date attribute in query method in spring boot repository. But it giving me " Failed to convert from type java.lang.String to type @org.springframework.data.repository.query.Param java.util.Date for value '2014-11-27" error. I have mentioned code segments the Entity class and Repository class below. What would be the problem here ?

Entity Class

@Column(name="date")
@Temporal(TemporalType.DATE)
private Date date;

Repository

public interface WeatherRepository extends CrudRepository<Weather, String> {
List<Weather> findAllByDate(@Param("date") Date date);
Weather findWeatherByCity(@Param("city") String city);

}

Answer 1

Try sending the date in this format - 11/27/2014 (MM/dd/yyyy) . This should be able to parse it from the request URI in this format. Please try and let me know.

Answer 2

You can use the @org.springframework.format.annotation.DateTimeFormat annotation on the date parameter to specify the format explicitly. In the annotation, you can use either the

• pattern to specify an arbitrary pattern (following the SimpleDateFormat patterns)
• iso to use one of the standard ISO formats
• style for a shorthand two-letter code for date and time formats ( S hort/ M edium/ L ong/ F ull/ - )

Choose only one of the configuration options.

Then you can use any of Date , Calendar , Long , Joda-Time types or (Spring 4 + JDK 8) java.time types as your parameter type.
