Spring Boot + JPA+Thymeleaf+Hibernate multiple validation annotation applied

Question

Before writing my problem, i have search a lot on internet. But i did not found any clue to overcome this issue.

My problem is multiple validation annotation applying of POJO field.

for Exp:

@NotNull
@Pattern(regexp="(^[0-9]{10})")
private String mobileNumber; 

If i do not enter any thing and left blank, then both the validation applied and both messages displayed. I just want one validation applied at a time and only one message display at a time.

I am using Spring boot and thymeleaf as template engine.

Answer 1

You have two way to solve this situation.

1. You may remove @NotNull . @Pattern annotation also does not accept null value and modify your error message.

2. Create custom validation annotation which combine two annotation in one.
