Question

我的问题是我无法按日期获取候选人，在我的代码中，我使用了如下的控制器和存储库

1- CandidatController

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

      @Autowired
      CandidatDao candidatdao;

      @GetMapping(value = "/GetAllCandidats")
      public List<Candidat> listeDesCandidat(){

          List<Candidat> candidats = candidatdao.findAll();
          return candidats;
      }    
      @GetMapping(value = "/GetAllCandidats/{date}")
      public List<Candidat> afficherCandidat(@PathVariable ("date") 
                      @DateTimeFormat(pattern="yyyy-MM-dd") Date date) {

          return  candidatdao.findByDate(date);
      }

2- CandidatDAO

  @Repository
  public interface CandidatDao extends JpaRepository <Candidat, String>{

    List<Candidat> findByDate(Date date);
   }

3- classcandidat

  @Entity
  public class Candidat {

     @Id
     @GeneratedValue
     @Column(name = "candidat_id")
     private int id;

     private String nom;
     private String prenom;
     private String ville;
     private int numTel;
     private String mail;
     private String pseudo;
     private String roleCible;
     private String typeContrat;
     private String villeRecherchee;

     @JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd")
     private Date date;

在浏览器中，结果是：与（http://localhost:8080/api/GetAllCandidats/）

 {
id: 1,
nom: "Sar",
prenom: "Samir",
ville: "tissemsilt",
numTel: 76676810,
mail: "kira.DJ@gmail.com",
pseudo: "FET",
roleCible: "INGENIEUR",
typeContrat: "CDI",
villeRecherchee: "NANTES",
techno: [ ],
date: "2019-04-16",
secteurActivites: [ ]
},
{
id: 2,
nom: "xxxx",
prenom: "yyyyy",
ville: "zzzzzz",
numTel: 76676810,
mail: "kira.DJ@gmail.com",
pseudo: "FET",
roleCible: "INGENIEUR",
typeContrat: "CDI",
villeRecherchee: "NANTES",
techno: [ ],
date: "2019-04-22",
secteurActivites: [ ]
},

但是对于（http://localhost:8080/api/GetAllCandidats/2019-04-22），结果为null：

我请您好好看看这个blog

我建议您在引用博客文章时使用以下代码。

@Temporal(TemporalType.DATE)
private Date date;

如何按日期“ findByDate”查找候选人
