Introduction

Contrôleur de repos de démarrage à ressort.

Dans cet exemple, je montrerai comment formuler un contrôleur de repos pour obtenir et publier des données dans la base de données en utilisant JPA avec le code le plus simple et le plus facile.

Dans cet exemple, nous ferons référence à la table de données nommée buyerRequirement.

BuyingRequirement.java

@Entity @Table (name = "BUYINGREQUIREMENTS") @NamedQueries ({@NamedQuery (name = "BuyingRequirement.findAll", query = "SELECT b DE BuyingRequirement b")}) Classe publique BuyingRequirementène serialVersionUID = 1L;

@Column(name = "PRODUCT_NAME", nullable = false)
private String productname;

@Column(name = "NAME", nullable = false)
private String name;

@Column(name = "MOBILE", nullable = false)
private String mobile;

@Column(name = "EMAIL", nullable = false)
private String email;

@Column(name = "CITY")
private String city;


public BuyingRequirement() {
}


public String getProductname() {
    return productname;
}

public void setProductname(String productname) {
    this.productname = productname;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getMobile() {
    return mobile;
}

public void setMobile(String mobile) {
    this.mobile = mobile;
}

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public String getCity() {
    return city;
}

public void setCity(String city) {
    this.city = city;
}

}

C'est la classe d'entité qui inclut le paramètre faisant référence aux colonnes de la table byuingRequirement et leurs getters et setters.

IBuyingRequirementsRepository.java (interface JPA)

@Repository
@RepositoryRestResource
public interface IBuyingRequirementsRepository extends JpaRepository<BuyingRequirement, UUID> {
   // Page<BuyingRequirement> findAllByOrderByCreatedDesc(Pageable pageable);
    Page<BuyingRequirement> findAllByOrderByCreatedDesc(Pageable pageable);
    Page<BuyingRequirement> findByNameContainingIgnoreCase(@Param("name") String name, Pageable pageable);
}

BuyingRequirementController.java

@RestController
@RequestMapping("/api/v1")
public class BuyingRequirementController {

    @Autowired
    IBuyingRequirementsRepository iBuyingRequirementsRepository;
    Email email = new Email();

    BuyerRequirementTemplate buyerRequirementTemplate = new BuyerRequirementTemplate();

    private String To = "[email protected]";
    // private String To = "[email protected]";
    private String Subject = "Buyer Request From Pharmerz ";

    @PostMapping(value = "/buyingRequirement")
    public ResponseEntity<BuyingRequirement> CreateBuyingRequirement(@RequestBody BuyingRequirement buyingRequirements) {

        String productname = buyingRequirements.getProductname();
        String name = buyingRequirements.getName();
        String mobile = buyingRequirements.getMobile();
        String emails = buyingRequirements.getEmail();
        String city = buyingRequirements.getCity();
        if (city == null) {
            city = "-";
        }

        String HTMLBODY = buyerRequirementTemplate.template(productname, name, emails, mobile, city);

        email.SendMail(To, Subject, HTMLBODY);


        iBuyingRequirementsRepository.save(buyingRequirements);
        return new ResponseEntity<BuyingRequirement>(buyingRequirements, HttpStatus.CREATED);
    }


    @GetMapping(value = "/buyingRequirements")
    public Page<BuyingRequirement> getAllBuyingRequirements(Pageable pageable) {

        Page requirements = iBuyingRequirementsRepository.findAllByOrderByCreatedDesc(pageable);
        return requirements;
    }

    @GetMapping(value = "/buyingRequirmentByName/{name}")
    public Page<BuyingRequirement> getByName(@PathVariable String name,Pageable pageable){
        Page buyersByName = iBuyingRequirementsRepository.findByNameContainingIgnoreCase(name,pageable);

        return buyersByName;
    }
}

Il comprend la méthode

1. Post méthode qui publie des données dans la base de données.
2. Obtenez la méthode qui récupère tous les enregistrements du tableau buyRequirement.
3. C'est aussi une méthode get qui trouvera l'exigence d'achat par le nom de la personne.
