One of composite primary key as foreign key

Question

I have below composite primary key in class below

  @Entity(name="data_req_id")
    @IdClass(Composite.class)
    public class DataRequestId{
    
      @Id
      @ManyToOne
      @JoinColumn(name="request_id")
      Request request;
      
     @Id
     String someId;
    }

public class Composite implements Serilizable{
     private Request request;
     private String someId;
     Composite(Request request, String someId){
          this.request =  request;
          this.someId = someId
   }
}

below is my request class:

@Entity
@DynamicUpdate
public class Request{
 
   @Id
   int id;
   // some other attributes
   @OneToMany(cascade={CascadeType.PERSIST}, mappedBy = "request")
    List<DataRequestId> dataReqId;

}
}

I want to know this is correct approach? to keep one composite key as foreign key in other table?
