Java Spring RestFull API

0 голосов
/ 03 января 2019

я пытаюсь узнать, как работает служба restful в Java. но я столкнулся с этой проблемой, которую я не могу понять. Я пытаюсь вызвать этот контроллер, который будет принимать данные и сохранять их в базе данных. но я получаю исключение, с которым я не сталкивался раньше если я удаляю класс модели в качестве параметра и пытаюсь вернуть только базовую строку, она работает нормально. но моя цель - сохранить все данные, которые передаются контроллеру, в базу данных. 

enter code here

person.java // класс модели 

@Entity
@Table(name = "Person")
@EntityListeners(AuditingEntityListener.class)
@JsonIgnoreProperties(value = {"createdAt", "updatedAt"}, allowGetters = true)

public class Person implements Serializable {

    @JsonProperty("key")
    public int getKey() {
        return key;
    }

    public void setKey(int key) {
        this.key = key;
    }


    @JsonProperty("name")
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

    @JsonProperty("m")
    public int getMotherKey() {
        return motherKey;
    }
    public void setMotherKey(int motherKey) {
        this.motherKey = motherKey;
    }
    @JsonProperty("f")
    public int getFatherKey() {
        return fatherKey;
    }
    public void setFatherKey(int fatherKey) {
        this.fatherKey = fatherKey;
    }

    @JsonProperty("dob")
    public int getDateOfBirth() {
        return DateOfBirth;
    }
    public void setDateOfBirth(int dateOfBirth) {
        DateOfBirth = dateOfBirth;
    }

    @JsonProperty("g")
    public String getGender() {
        return gender;
    }
    public void setGender(String gender) {
        this.gender = gender;
    }



    public Person() {



    }


    @NotNull
    int key;    
    @NotBlank
    String name;
    @NotNull
    int motherKey;
    @NotNull
    int fatherKey;
    @NotNull
    int DateOfBirth; //19921210->December 10th 1992 
    @NotBlank
    String gender;

** Класс контроллера **

package com.example.FamilyTree;
import java.util.List;
import javax.validation.Valid;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.DeleteMapping;
import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import Repository.TreeRepository;
import exception.ResourceNotFoundException;
import model.Person;




@RestController
@RequestMapping("/api")
public class FamilityTreeController {


    TreeRepository  treeRepository;



    @PostMapping("/addPerson")
    public Person addPerson(@Valid @RequestBody Person person) {


        return treeRepository.save( person);

    }
}

Проблема в том, что treeRepository не вводится Spring и, следовательно, null.

Сначала убедитесь, что TreeRepository правильно настроен, добавив @EnableJpaRepositories(basePackages = "<package of your repository interface>")) в свой класс конфигурации Spring (FamilyTreeApplication).

Затем, чтобы добавить его правильно, вы должны либо добавить аннотацию @Autowired: 

@Autowired
private TreeRepository treeRepository;

или добавьте его в конструктор, что является предпочтительным способом для команды Spring. 

private TreeRepository treeRepository;

//@Autowired not needed, implicit as of Spring 4.3
public FamilityTreeController(TreeRepository treeRepository) {
  this.treeRepository = treeRepository;
}

Также есть что-то не так с вашей иерархией пакетов, которая может повлиять на то, как Spring Boot находит компоненты: ваш основной класс конфигурации (FamilyTreeApplication) должен находиться в «базовом пакете» приложения, а все остальные классы в подпакетах, что-то вот так: 

com.example.familytree
|_ FamilyTreeApplication.java
|_ controller
   |_ FamilyTreeController.java
|_ repository
   |_ TreeRepositry.java

Лучше всего, если вы используете класс обслуживания

Эта аннотация служит специализацией @Component, позволяя автоматически определять классы реализации при сканировании пути к классам. 

@Service
public class TreeService {
      @Autowired
      TreeRepository treeRepository;

      public Person save(Person person) {
         return treeRepository.save(person);
      }
}

Измените свой класс контроллера следующим образом: 

@RestController
@RequestMapping("/api")
public class FamilityTreeController {

@Autowired 
TreeService  treeService;

@PostMapping("/addPerson")
public Person addPerson(@Valid @RequestBody Person person) {
    return treeService.save( person);
   }
}

Пожалуйста, сделайте имена пакетов строчными и следуйте соглашению об именах :

Измените это: Repository.TreeRepositoryна это: com.example.repository.TreeRepository и для других тоже: com.example.model.Person com.example.exception.ResourceNotFoundException

Вам не хватает аннотации @Repository в вашем хранилище: 

@Repository
public interface TreeRepository extends JpaRepository<Person, Integer> { }

И не забудьте добавить @Autowired для добавления в хранилище: 

    @Autowired
    private TreeRepository treeRepository;

ОБНОВЛЕНИЕ

Кажется, что Spring не может найти бин даже с добавленным @Repository.Я бы посоветовал вам поместить все ваши пакеты в com.example и добавить конфигурацию component scan, ссылающуюся на этот пакет.
