Hello.
The trick here is the following line
> car.setInspirations(List.of(new Car(), new Car()));
Ignite serialize as a binary collection only *some* implementation of List
interface.
Others serialized using standard java serialization.
I rewrite your code and now it’s working as expected:
```
public class SimpleTest extends GridCommonAbstractTest {
@Test
public void testGetCarInspirationsWithBinaryapi() throws Exception {
Ignite ignite = startGrid(0);
Car car = new Car();
car.setName("carname");
car.setWeight(BigDecimal.ONE);
List<Car> inspirations = new ArrayList<>();
inspirations.add(new Car());
inspirations.add(new Car());
car.setInspirations(inspirations);
ignite.getOrCreateCache("Sample").put("carname", car);
IgniteCache<String, BinaryObject> binaryCarCache =
ignite.getOrCreateCache("Sample").withKeepBinary();
List<BinaryObject> carInspirations =
binaryCarCache.get("carname").field("inspirations");
assertEquals(2, carInspirations.size());
assertTrue(carInspirations.get(0) instanceof BinaryObject);
BinaryObject binaryCar = carInspirations.get(0);
assertNull(binaryCar.field("name"));
}
public class Car implements Serializable {
private String name;
private List<Car> inspirations;
private BigDecimal weight;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<Car> getInspirations() {
return inspirations;
}
public void setInspirations(List<Car> inspirations) {
this.inspirations = inspirations;
}
public BigDecimal getWeight() {
return weight;
}
public void setWeight(BigDecimal weight) {
this.weight = weight;
}
}
}
```
