Sort by field of embeded object not work in Spring Data JPA

[Layne_Peng]

Hello, guys,

I am using Spring Data JPA in one of our project. The JPA structure like:

Class A {
B b;
String c;
}

Class B {
String d;
}

I wanna do a query on Class A but sort by b.d. How can I do it? I cannot find any clue on Spring Data JPA document.

I wanna explained here. I hope the sort is dynamical when the sort field given by client, instead use @OrderBy annotation.

new Sort("b.d", Direction.ASC) should do the trick.

new Sort("b.d", Direction.ASC) should do the trick.

Which version of Spring Data you are mentioned. I am using 1.0.0 M3, not work.
