An entity has a HashMap as property, property is convertered using an AttributeConverter.
After updating the hashmap, the dirty check does not flag this property as dirty and no update is done.
{noformat}@Entity
@Table(name = "person")
public class Person {
@Id
private int id;
...
@Convert(converter = HashMapConverter.class)
private Map<String, Object> attributes = new HashMap<>();
...
}
public class HashMapConverter implements AttributeConverter<HashMap<String, Object>, String> {
private final ObjectMapper mapper = new ObjectMapper();
@Override
public String convertToDatabaseColumn(HashMap<String, Object> stringObjectHashMap) {
try {
return mapper.writeValueAsString(stringObjectHashMap);
} catch (JsonProcessingException e) {
throw new RuntimeException(e);
}
}
@Override
public HashMap<String, Object> convertToEntityAttribute(String string) {
try {
return mapper.readValue(string, new TypeReference<>() {});
} catch (IOException e) {
throw new RuntimeException(e);
}
}
}{noformat}
*test case* is here: [github|https://github.com/BartVansegbroeck/hhh16105]
I’ve added a failing test case in orm/hibernate-orm-6
and a working test case with the same setup in orm/hibernate-orm-5
