Я не могу заставить мой sql-запрос работать, я думаю, что проблема связана с "AssignmentServiceImpl.java"
У меня есть 2 таблицы (проект и участник), одна из которых - объединение (назначение).
... идея, пожалуйста? вот мой код:
AppController:
``
@Controller
public class AppController {
@Autowired
private AssignmentService assignmentService;
@GetMapping({"/listAssignments"})
public String listAssignment(ModelMap model) {
List<Assignment> assignments = assignmentService.fetchAllAssignments();
model.addAttribute("assignments", assignments);
return "allAssignments";
}
``
Назначение DAO:
``
@Repository
public interface AssignmentDao extends CrudRepository<Assignment, Integer> {
//Permet d'afficher la liste des assignments
@Query("select project.PROJECT_NAME, contributor.FIRST_NAME, assignment.START_DATE, assignment.END_DATE" +
" from project inner join assignment on assignment.id_ASSIGNMENT=project.ID_PROJECT " +
"inner join contributor on contributor.id=assignment.id_ASSIGNMENT")
List<Assignment> fetchAllAssignments();
}
``
Служба назначения:
``
public interface AssignmentService {
List<Assignment> fetchAllAssignments();
}
``
AssignmentServiceImpl:
``
@Service("assignmentService")
public class AssignmentServiceImpl implements AssignmentService {
@Autowired
private AssignmentDao dao;
public List<Assignment> fetchAllAssignments() {
return dao.fetchAllAssignments();
}
}
``
Назначение:
``
@Entity
@Table(name="ASSIGNMENT")
public class Assignment {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id_ASSIGNMENT", nullable = false)
private int id;
@ManyToOne
private Project project;
@ManyToOne
private Contributor contributor;
get and set
@Override
public String toString() {
return "Assignment [startDate=" + startDate + ", endDate=" + endDate + ", assignmentRate="
+ assignmentRate + ", activity=" + activity + "]";
}
``
Проект:
``
@Entity
@Table(name="PROJECT")

@Column(name = "ID_PROJECT", nullable = false)

@Column(name = "PROJECT_NAME", nullable = false)
private String projectName;
@OneToMany(mappedBy="project", fetch = FetchType.LAZY)

@Override
