javax.validation.constraints @Email not return custom message and regex?

I am new in validation.

controller:

@Validated
@RestController
public class AccountController
{
    @PostMapping( value = "/account/location" )
    public ResponseEntity<LocationAccountVO> createLocationAccount( @RequestHeader 
HttpHeaders headers,@Valid @RequestBody LocationAccountVO locationAccountVO ) throws 
NumberParseException
    {
        return ResponseEntity.status(HttpStatus.CREATED).body( 
accountService.createLocationAccount( locationAccountVO ) );
    }
}

LoacationVo.java:

@Data
@JsonInclude( JsonInclude.Include.NON_NULL )
public class LocationAccountVO
{
private UUID locationId;
    @NotNull(message = "Email is mandatory.")
    @Email( regexp = ValidationConstant.EMAIL, message = "Email be valid")
    private String email;
}

public static final String EMAIL = "\\\\b[A-Z]+@[A-Z0-9.-]+\\\\.[A-Z]{2,4}\\\\b";

but @Email not giving custom message and pattern also not working.Kindly solve my problem.

Thanks.

1- Add the necessary dependencies in pom.xml file from Maven Central:

  • spring-boot-starter-web
  • spring-boot-starter-validation

2- Add the necessary Annotations in your form bean:

@NotEmpty(message = "{email.notempty}")
@Email
private String email;

3- To read messages from message.properties, you have to define the MessageSource Bean

@Bean
public ResourceBundleMessageSource messageSource() {
    final ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
    messageSource.setBasename("messages");
    messageSource.setUseCodeAsDefaultMessage(Boolean.parseBoolean("true");
    messageSource.setDefaultEncoding("UTF-8");
    return messageSource;
}

4- To avoid having the custom validator ignored, you have to set the validator by overriding the getValidator() method. Set validation message source to message.properties.

@Bean(name = "validator")
@Override
public LocalValidatorFactoryBean getValidator() {
    LocalValidatorFactoryBean bean = new LocalValidatorFactoryBean();
    bean.setValidationMessageSource(messageSource());
    return bean;
}

5- in the message.properties file under src/main/resources just define a property message like:

email.notempty=This field is required.

note : If it does not work yet you can still do this.

javax.validation.constraints.Email.message=Please provide valid email id.

You can implement like that.

@Data
@JsonInclude( JsonInclude.Include.NON_NULL )
public class LocationAccountVO
{
private UUID locationId;
    @NotEmpty(message = "Email is mandatory.")
    @Pattern(regexp = "^[A-Z0-9._%+-]+@[A-Z0-9.-]+\\.[A-Z]{2,6}$", message = "Email be valid")
    private String email;
}
