在Postman中使用REST控制器測試Spring應用

Question

所以，我的代碼是這樣的：

BasicApp.java

@SpringBootApplication(exclude=HibernateJpaAutoConfiguration.class)
public class BasicApp {

    public static void main(String[] args) {
        SpringApplication.run(BasicApp.class, args);
    }
}

ControllerHome.java

@Controller
@RequestMapping()
public class ControllerHome {
    @RequestMapping(method = RequestMethod.GET)
    public String index() {
        return "index";
    }
}

LessonController.java

@Slf4j
@Controller
@RequestMapping
@SessionAttributes({"types", "positions", "lectureList", "published"})
public class ControllerLecture {

    List<Lecture> lectureList= new ArrayList<>();

    @RequestMapping
    public String newLecture() {

        return "newLecture";
    }

    @GetMapping("/newLecture")
    public String showForm(Model model, Lecture lecture) {

        log.info("Filling data to show form.");

        model.addAttribute("lecture", new Lecture ());
        model.addAttribute("types", Lecture.LectureType.values());
        model.addAttribute("positions", Lecturer.LecturerPositions.values());
        model.addAttribute("published", lecture.getPublished());

        return "newLecture";
    }

    @GetMapping("/allLectures")
    public String showLectures() {

        return "allLectures";
    }

    @GetMapping("/resetCounter")
    public String resetCounter(SessionStatus status) {

        lectureList.clear();
        status.setComplete();
        return "redirect:/newLecture";
    }

    @PostMapping("/newLecture")
    public String processForm(@Valid Lecture lecture, Errors errors, Model model) {

        log.info("Processing lecture: " + lecture);

        if(errors.hasErrors()) {

            log.info("Lecture has errors. Ending.");

            return "newLecture";

        } else {

            lectureList.add(lecture);

            model.addAttribute("numberOfLectures", lectureList.size());

            model.addAttribute("lecture", lecture);

            model.addAttribute("published", lecture.getPublished());

            model.addAttribute("lectureList", lectureList);

            log.info("Lecture successfully saved: " + lecture);

            return "output";
        }
    }
}

LectureRestController.java

@RestController
@RequestMapping(path="/lecture", produces="application/json")
@CrossOrigin(origins="*")
public class LectureRestController {

    @Autowired
    LectureRepository lectureRepository;

    @GetMapping
    public Iterable<Predavanje> findAll() {

        return lectureRepository.findAll();
    }

    @GetMapping("/{id}")
    public ResponseEntity<Lecture> findOne(@PathVariable Long id) {

        Lecture lecture = lectureRepository.findOne(id);

        if(lecture != null) {

            return new ResponseEntity<>(lecture, HttpStatus.OK);
        } else {

            return new ResponseEntity<>(null, HttpStatus.NOT_FOUND);
        }
    }

    @ResponseStatus(HttpStatus.CREATED)
    @PostMapping(consumes="application/json")
    public Lecture save(@RequestBody Lecture lecture) {

        return lectureRepository.save(lecture);
    }

    @PutMapping("/{id}")
    public Predavanje update(@RequestBody Lecture lecture) {

        lectureRepository.update(lecture);

        return lecture;
    }

    @ResponseStatus(HttpStatus.NO_CONTENT)
    @DeleteMapping("/{id}")
    public void delete (@PathVariable Long id) {

        lectureRepository.delete(id);
    }
}

LectureRepository.java（接口）

import ... .Lecture;

public interface LectureRepository {

    Iterable<Lecture> findAll();

    Lecture findOne(Long id);

    Lecture save(Lecture lecture);

    Lecture update(Lecture lecture);

    void delete(Long id);
}

HibernateLectureRepository.java

@Primary
@Repository
@Transactional
public class HibernateLectureRepository implements LectureRepository {

    private SessionFactory sessionFactory;

    @Autowired
    public HibernateLectureRepository(SessionFactory sessionFactory) {

        this.sessionFactory = sessionFactory;
    }

    @Override
    public Iterable<Lecture> findAll() {

        return sessionFactory.getCurrentSession().createQuery("SELECT p FROM Lecture p", Lecture.class).getResultList();
    }

    @Override
    public Lecture findOne(Long id) {

        return sessionFactory.getCurrentSession().find(Lecture.class, id);
    }

    @Override
    public Lecture save(Lecture lecture) {

        lecture.setEntryDate(new Date());
        Serializable id = sessionFactory.getCurrentSession().save(lecture);
        lecture.setId((Long)id);

        return lecture;
    }

    @Override
    public Lecture update(Lecture lecture) {

        sessionFactory.getCurrentSession().update(lecture);

        return lecture;
    }

    @Override
    public void delete(Long id) {

        Lecture lecture = sessionFactory.getCurrentSession().find(Lecture.class, id);
        sessionFactory.getCurrentSession().delete(lecture);
    }

}

使用Postman工具測試此應用程序時出現問題。 我知道在Spring Tool Suite中啟動應用程序后，我轉到站點（localhost：8080）並在那里輸入數據（基本講義數據：名稱，簡短內容，講師...），但是當我鍵入URL時在郵遞員里 http：// localhost：8080 / lecture / 1 ，結果什么也沒打印出來，我也不知道為什么。

我使用的模板是：index.html（主頁），login.html（登錄頁面），output.html（顯示之前輸入的講座數據的頁面），newLecture.html（用於輸入講座的表單）和allLectures。 html（顯示所有已創建演講的輸出的頁面）。 我沒有LectureRestController.java類中提到的任何名為“ lecture”的模板，這是問題嗎？ 因為如果是這樣，我不知道該如何創建一個將填充有關講座數據的文件。

更新：

這是郵差的反應在打字時的http：//本地主機：8080 /演講 postman1這是郵差的反應在打字時的http：//本地主機：8080 /演講/ 1 postman2

Answer 1

我已經解決了，問題是我實際上沒有在LessonController.java類中，特別是在else塊中的processForm方法中調用方法.save() 。 我已經創建了HibernateLectureRepository.java類的@Autowired實例，然后在上述位置插入了該實例，並調用了.save()方法。

感謝@EbertToribio在評論中提供的幫助。
