I am facing problem with postman.
I am trying to test a rest end point url using Postman. It is spring boot application.

Here, I am sending 9 parameters in request body to controller but controller receives only 6 parameters, rest three parameters controller receives as null. Due to this, I am getting jakarta.validation.ConstraintViolationException: because these parameters can’t be null.

Postman Image is –

Exception is –

jakarta.validation.ConstraintViolationException: Validation failed for classes [com.validate.validate_barcode.entity.Corporate] during persist time for groups [jakarta.validation.groups.Default, ]
List of constraint violations:[
    ConstraintViolationImpl{interpolatedMessage='must not be null', propertyPath=spocMobile, rootBeanClass=class com.validate.validate_barcode.entity.Corporate, messageTemplate='{jakarta.validation.constraints.NotNull.message}'}
    ConstraintViolationImpl{interpolatedMessage='must not be null', propertyPath=spocName, rootBeanClass=class com.validate.validate_barcode.entity.Corporate, messageTemplate='{jakarta.validation.constraints.NotNull.message}'}
    ConstraintViolationImpl{interpolatedMessage='must not be null', propertyPath=spocEmail, rootBeanClass=class com.validate.validate_barcode.entity.Corporate, messageTemplate='{jakarta.validation.constraints.NotNull.message}'}
]

    at org.hibernate.boot.beanvalidation.BeanValidationEventListener.onPreInsert(BeanValidationEventListener.java:81) ~[hibernate-core-6.5.2.Final.jar:6.5.2.Final]

Entity Class is

@Entity
@Table(name = "corporate")
public class Corporate extends Auditable<String>{

    // Primary ID which increments automatically when new entry is added into the
    // database
    @Id
    //@GeneratedValue(strategy = GenerationType.AUTO)
    @GeneratedValue(strategy = GenerationType.AUTO, generator = "native")
   // @GenericGenerator(name = "native", strategy = "native")
    int id;

    // UCIC = Unique Corporate Identification Code 
    @Column(name = "ucic", length = 9)
    @NotNull
    private String ucic;

    @Column(name = "corp_name")
    @NotNull
    private String corpName;

    @Column(name = "category")
    @NotNull
    private String category;

    @Column(name = "corp_email")
    @NotNull
    private String corpEmail;

    @Column(name = "corp_mobile")
    @NotNull
    private String corpMobile;

    @Column(name = "corp_address")
    @NotNull
    private String corpAddress;

    @Column(name = "spoc_email")
    @NotNull
    private String spocEmail;
    
    @Column(name = "spoc_name")
    @NotNull
    private String spocName;

    @Column(name = "spoc_mobile")
    @NotNull
    private String spocMobile;
    
    
    public Corporate() {
        super();
    }
     
//setter and Getter

}

And Controller Class is –

public class CorporateController {

    // Annotation
    @Autowired
    private CorporateService corporatService;

    // Save operation
    //@PostMapping("/saveCorporate")
    @RequestMapping(value = "/saveCorporate" , method = RequestMethod.POST, produces = "application/json")
    public Corporate saveCorporate(@RequestBody Corporate corporate) {
        System.out.println("Post Mapping - saveDepartment");
        System.out.println(corporate.toString());
        return corporatService.saveCorporate(corporate);
    }
}

Can some one please help me on this?
Thanks.
