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;
..
}

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
}
