Spring Data Rest嵌套属性与JsonUnwrapped一起排序

Question

So, I have this class, using @EmbeddedId and @JsonUnwrapped annotations

@Entity
class Order {
    @EmbeddedId @JsonUnwrapped
    private OrderPK pk;
    private String field1;
    private String field2;
    //...getters, setters
}

And this is the primary key class

@Embeddable
class OrderPK implements Serializable {
    private String orderNumber;
    private String company;
    //...getters, setters
}

I wanted to make Spring Data REST sorting treat the fields in the PK class as top-level instead of nested. Basically, I want to use this one: .../orders?sort=orderNumber,desc , instead of .../orders?sort=pk.orderNumber,desc . I couldn't find any way to do this in the documentations.

Answer 1

You can no longer achieve your goal, if you are using the @EmbeddedId option to implement your composite key. The reason is that the attributes under the hood of EmbeddedId class cannot be taken out as flat parameters.

Note that @JsonUnwrapped is not intended to perform that task.

You can use the following option instead of @EmbeddedId to achieve your goal.

• Use @IdClass . Follow this example .
