I tried to implement entity classes using polymorphism.
This is my BaseEntity
@Getter
@Setter
@Accessors(chain = true)
@MappedSuperclass
@NoArgsConstructor
@AllArgsConstructor
@EntityListeners(AuditingEntityListener.class)
public class BaseEntity {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Size(max = 55, message = "name length more then 55")
private String name;
@Size(max = 255, message = "remark length more than 255")
private String remark;
}
And my entity
@Data
@NoArgsConstructor
@Table(name = "sys_user")
@Entity(name = "sys_user")
@Accessors(chain = true)
@ToString(callSuper = true)
@EqualsAndHashCode(callSuper = true)
public class SysUser extends BaseEntity implements Serializable {
@NonNull
private String username;
@NonNull
private String password;
}
In my controller
@Controller
@GraphQLApi
@RequiredArgsConstructor
public class SysUserController implements BaseController {
private final SysUserRepository sysUserRepository;
@GraphQLQuery
public List<SysUser> sysUsers() {
return sysUserRepository.findAll();
}
}
My GraphQL Config
@Configuration
@RequiredArgsConstructor
public class GraphQLConfig {
private final @NotNull List<BaseController> controllerLists;
@Bean
public GraphQLSchema graphqlSchema() {
GraphQLSchemaGenerator generator = new GraphQLSchemaGenerator();
generator.withOperationsFromSingletons(controllerLists.toArray());
return generator.generate();
}
}
Now, I try to get
{
sysUsers {
username
}
}
The result is right
{
"data": {
"sysUsers": [
{
"username": "Hello"
}
]
}
}
But I try to get the parent class field:
{
sysUsers {
name
}
}
I will get a error
{
"errors": [
{
"message": "Validation error of type FieldUndefined: Field 'name' in type 'SysUser' is undefined @ 'sysUsers/name'",
"locations": [
{
"line": 3,
"column": 5
}
]
}
]
}
I use io.leangen.graphql:graphql-spqr-spring-boot-starter:0.0.4
How to resolve this question?
Thanks!
