获取属于特定学生的表格列表

Question

我有 Form 和 Student 的 class。一个学生可能有 0 个或多个表格。我将它们之间的关系设置为OneToMany。现在，我需要获取特定学生拥有的表格。那时我有两个问题。我应该如何获取 URL 中的那些表格？假设我想获取 id=7 的学生的表格。

选项 1：

api/v1/forms?studentId=7

选项 2：

api/v1/students/7/forms

其中哪一个用得最多或者比较合理？第二个问题是。通常，当我想向 JpaRepo 添加一个新方法时。我只需要添加 Jpa 提供的方法，使得 findAll、findByStudentId。因为我在 Student entity/model 中有一个表格列表。我怎样才能获取所有表格？我应该使用哪个命名方法？综上所述，我需要知道我应该把方法写在FormDataAccess还是StudentDataAccess。方法名称应该是什么？

@Data
@Entity
@Table(name = "student")
public class Student {
    @Id
    @Column(name = "Student_id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    @Column(name = "Student_name")
    private String name;
    @Column(name = "Course_id")
    private int courseID;
    @Column(name="Oasis_id")
    private Long oasisID;

    @OneToMany(mappedBy = "student",fetch = FetchType.LAZY)
    @JsonIgnore
    private List<Form> forms;
}

表单模型

@Data
@Entity
@Table(name="form")
public class Form {

    @Id @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;

    @ManyToOne
    @JoinColumn(name = "Student_id", nullable = false)
    private Student student;

    @ManyToOne
    @JoinColumn(name = "Attending_id", nullable = false)
    private AttendingPhysician attending;
    @Column(name = "Kayit_no", nullable = false)
    private String kayitNo;

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

    @Column(name = "Yas", nullable = false)
    private int yas;

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

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

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

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

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

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

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

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

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

    @Column(name="Date_sent", nullable = false)  // Convert to timestamp using java Date @CreationTimestamp, @UpdateTimestamp
    private String dateSent;



}

Answer 1

解决方法很简单。

我只需要在 FormDataAccess 中写一个查询。

@Query(" from Form where student.id = :studentId")
List<Form> findFormByStudentId(int studentId);

现在我可以使用此路径检索表单

api/v1/forms/student/7

我仍然想知道如何从学生端而不是表单端检索表格，这样

api/v1/student/7/forms

获取属于特定学生的表格列表

Fetch list of forms that are belong to a specific student

java

spring

hibernate

jpa

spring-boot
