Failed to convert from type [java.lang.String] to type [java.sql.Time]

Question

Can't get time field from input, constantly getting error message:

Field error in object 'recipe' on field 'prepTime': rejected value [04:00]; codes [typeMismatch.recipe.prepTime,typeMismatch.prepTime,typeMismatch.java.sql.Time,typeMismatch];

arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [recipe.prepTime,prepTime]; arguments []; default message [prepTime]]; default message [Failed to convert property value of type [java.lang.String] to required type [java.sql.Time] for property 'prepTime'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [@org.springframework.format.annotation.DateTimeFormat java.sql.Time] for value '04:00'; nested exception is org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.util.Date] to type [@org.springframework.format.annotation.DateTimeFormat java.sql.Time]]

My POJO class:

@Entity
public class Recipe {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Lob
    private byte[] photo;

    @Size (min=3, max=100, message = "size of field Name must be between 3 and 100")
    private String name;

    private String description;

    @ManyToOne
    private Category category;

    @DateTimeFormat(pattern = "mm:ss")
    private Time prepTime;

    @DateTimeFormat(pattern = "mm:ss")
    private Time cookTime;

    private String addedFlag;

and input field in form html:

<input type="time" th:placeholder="${recipe.prepTime}" th:field="${recipe.prepTime}"/>

So, what I'm doing wrong?
