jersey – java.lang.AbstractMethodError: when returning javax.ws.rs.core.Response object-Exceptionshub

Questions:

I am trying to return a javax.ws.rs.core.Response object from a REST api calls using PostMan. Truthfully I am not aware how I can return a Response object and how to use Jersey. Following is the code:

@PostMapping("/add/{name}/{email}/{roles}")
@Produces({MediaType.APPLICATION_JSON})
public Response addUser(@PathVariable("name") String name, @PathVariable("email") String email,
                        @PathVariable(value = "roles", required = true) List<String> roles) {

    User user = userService.addUser(name, email, roles);
    // return user;
    return Response.ok().entity(user).build();
}

If I return the user object instead of Response, it works fine. I have added the @ Produces annotation while I was searching for the solution but it does not help.

A similar question was asked here but the answer which other people have mentioned in their comments has been removed.

EDIT: Following is the User entity

@Component
public class User {
String name;
String email;
List<String> roles;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public List<String> getRoles() {
return roles;
}
public void setRoles(List<String> roles) {
this.roles = roles;
}
@Override
public String toString() {
return "User{" +
"name='" + name + '\'' +
", email='" + email + '\'' +
", roles=" + roles +
'}';
}
}
