Why does not delete data in rest api - spring-boot

Question

I am working on rest api. I got error while delete data by id. All code is complete but don't know why postman fire error. I can map two table with unidirectional mapping using hibernate.
Here down is error in postman:
"message": "Required request body is missing: public org.springframework.http.ResponseEntity<org.springframework.http.HttpStatus> com.rest.RestApiPojo.Controller.PojoController.deleteAddressPerson(com.rest.RestApiPojo.Entity.Person,java.lang.Integer)"
Here down is my code:
Entity
public class Person {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer person_id;
private String name;
#JsonManagedReference
#OneToOne(cascade = CascadeType.ALL, mappedBy = "person")
private Address address;
// getter setter
}
#Table(name = "address_master")
public class Address {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer address_id;
private String city;
private String country;
#JsonBackReference
#OneToOne(cascade=CascadeType.ALL, targetEntity = Person.class)
#JoinColumn(name = "person_id")
private Person person;
// getter setter
}
SeviceImpl
#Override
public void deleteAddressPerson(Integer personId) {
personRepo.deleteById(personId);
}
Controller
#RequestMapping(value = "/dltpersonaddress/{personId}", method = RequestMethod.DELETE)
public ResponseEntity<HttpStatus> deleteAddressPerson(#RequestBody Person person, #PathVariable Integer personId)
{
pojoService.deleteAddressPerson(personId);
return new ResponseEntity<>(HttpStatus.OK);
}

Answer 1

You have an unused #RequestBody Person person parameter in your controller method.
#RequestMapping(value = "/dltpersonaddress/{personId}", method = RequestMethod.DELETE)
public ResponseEntity<HttpStatus> deleteAddressPerson(#RequestBody Person person, #PathVariable Integer personId)
{
pojoService.deleteAddressPerson(personId);
return new ResponseEntity<>(HttpStatus.OK);
}
The error message explains that this param is obligatory, and requests without it wont be processed.
Remove the param to solve the issue.
