Answer a question

I can't make a request via postman, I checked everything, my email is represented as varchar(255) in my database. I use postgresql. Error: Required String parameter 'email' is not present. I used response and set it like this: @RequestParam(value = "params", required = false) String params for each received value, but this didn't help, as the program reported that we didn't send anything. What does this have to do with? The request is correct, as well as the accepted parameters are correct.

What the request looks like:

{
    "email" : "qwerty@mail.ru",
    "name" : "Vasya",
    "surname" : "Puk",
    "phone" : 1234562,
    "role":"ADMIN"
}

Entity USER

@Data
@Entity
@Table(name = "user", schema = "task")
public class User {

    @Id
    @GeneratedValue(strategy= GenerationType.IDENTITY)
    @Column(name = "id")
    private Long id;

    @OneToMany(cascade = {CascadeType.DETACH, CascadeType.MERGE, CascadeType.PERSIST,
            CascadeType.REFRESH
    })
    @JoinColumn(name = "id")
    private List<Role> role;

    @OneToMany(mappedBy = "user")
    private Set<Contract> contract;

    @Column(name = "surname", nullable = false)
    private String surname;
    @Column(name = "name", nullable = false)
    private String name;
    @Column(name = "email", nullable = false, unique = true)
    private String email;
    @Column(name = "phone", nullable = false, unique = true)
    private Integer phone;
}

The controller that accepts:

@PostMapping
    public String userPostAdd(@RequestParam String email, @RequestParam Integer phone, @RequestParam String name, @RequestParam String surname, @RequestParam String role) {
        Roles roles = null;
        System.out.println("TEST");
        System.out.println(roles.equalsName(role));
        System.out.println("TEST");
        //if ()
        //userRepository.save(requestUserDetails);
        return "User add;
    }

Repo:

@Repository
public interface UserRepository extends CrudRepository<User, Long> {
}

Answers

This controller seems to be incorrect.

@PostMapping
public String userPostAdd(@RequestParam String email, @RequestParam Integer phone, @RequestParam String name, @RequestParam String surname, @RequestParam String role) {
     //body
}

It should be like this :

@PostMapping
public String userPostAdd(@RequestBody User user) {
     //body
}

User is your object request, similar as your User entity
