javax.validation.UnexpectedTypeException: HV000030: No validator could be found for type: java.lang.Integer

I have to take input for paper_name and date_of_birth as int and date datatype respectively from a form.

Below is the code:

<li> Number:<input type="text" name="paper_number" ></li>
< li>date of birth: <input type="text" name="date_of_birth"></ li>

I have paperNumber and dateOfBirth variable in the controller as int and Date datatypes respectively.

Please help me change the datatype of paper_number and date_of_birth from string to int and date respectively.

I have seen other answers on stackoverflow and they have used jstl for the same but I am not able to figure out how to apply it here.

Controller code:

@RequestMapping(value = "/student" , params = "add", method = RequestMethod.POST )
       public String postAddStudent(
                   @RequestParam("date_of_birth" ) Date date,
                   @RequestParam("paper_number" ) int paperNumber)

Below is the EntityClass

public class EntityClass extends BaseEntity {

@Column(name = "DATE_OF_BIRTH", nullable = false)
    @NotBlank
    @DateTimeFormat(pattern = "dd-mm-yyyy")
    private Date dateOfBirth;//TODO

    @Column(name = "PAPER_NUMBER")
    private short paperNumber;
..

}

Below is the log

description The server encountered an internal error () that prevented it from fulfilling this request.

Hope you're using validation in hibernate like this,

@NotBlank
private Date some;

@NotBlank is for String type. There is no concept of java.util.Date being blank. It can be null or not null.. Use @NotNull instead,

@NotNull
@DateTimeFormat(pattern = "dd-mm-yyyy")
private Date dateOfBirth;

See Balus answer and @NotBlank for more details.

Update

HTTP Status 400: The request sent by the client was syntactically incorrect.

For the above error in Date type try add @DateTimeFormat annotation and mention the format of date you giving as input (say yyyy-mm-dd). Like below,

@RequestMapping(value="/fetch" , method=RequestMethod.GET)
public @ResponseBody String fetchResult(@RequestParam("from")   @DateTimeFormat(pattern="yyyy-MM-dd") Date fromDate) {
    //Content goes here
}
