Spring Data Rest Post子资源

Question

I am using spring data rest and want to post a new resource and its sub-resource.Both of them are new resource so there is no link pointing to either of them.In fact,the following json is a reasonable json I think to post the new resource and its sub-resource .

here is a json represents one new student.

{
  "name": "John",
  "sex": "man",
  "details": [
    {
      "detailKey": "weight",
      "detailValue": 130
    },
    {
      "detailKey": "height",
      "detailValue": 175
    },
  ]
}

details of this student is sub-resource and not exist in databases.

how I post John and his details at the same time(in one json or in one request),or there is a more proper way to do this?

PS: Student class

@Entity
@Table(name = "student", catalog = "test")
public class Student implements java.io.Serializable {

    // Fields

    private Integer id;
    private String name;
    private String sex;

    // Constructors

    /** default constructor */
    public Student() {
    }

    /** full constructor */
    public Student(String name, String sex) {
        this.name = name;
        this.sex = sex;
    }

    // Property accessors
    @Id
    @GeneratedValue(strategy = IDENTITY)
    @Column(name = "id", unique = true, nullable = false)
    public Integer getId() {
        return this.id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    @Column(name = "name")
    public String getName() {
        return this.name;
    }

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

    @Column(name = "sex")
    public String getSex() {
        return this.sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

}

StudentDetails class

@Entity
@Table(name = "student_details", catalog = "test")
public class StudentDetails implements java.io.Serializable {

    // Fields

    private Integer id;
    private Integer studentId;
    private String detailCode;
    private String detailValue;

    // Constructors

    /** default constructor */
    public StudentDetails() {
    }

    /** full constructor */
    public StudentDetails(Integer studentId, String detailCode,
            String detailValue) {
        this.studentId = studentId;
        this.detailCode = detailCode;
        this.detailValue = detailValue;
    }

    // Property accessors
    @Id
    @GeneratedValue(strategy = IDENTITY)
    @Column(name = "id", unique = true, nullable = false)
    public Integer getId() {
        return this.id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    @Column(name = "student_id")
    public Integer getStudentId() {
        return this.studentId;
    }

    public void setStudentId(Integer studentId) {
        this.studentId = studentId;
    }

    @Column(name = "detail_code")
    public String getDetailCode() {
        return this.detailCode;
    }

    public void setDetailCode(String detailCode) {
        this.detailCode = detailCode;
    }

    @Column(name = "detail_value")
    public String getDetailValue() {
        return this.detailValue;
    }

    public void setDetailValue(String detailValue) {
        this.detailValue = detailValue;
    }

}

StudentDetails is used to customize student's information.

both of id is auto increment,and I want to post one new student and his details info in the same request(I think it is friendly to the user)

Answer 1

Spring doesn't have first-class support for sub-resource (JAX-RS does). You will either have to do 2 calls from the client, or handle it on the server. It's not clear from your question how details can be a resource; it has no id. Weight and height don't uniquely identify a person. It seems your design is wrong, or you need to provide more information.
