I have a JSON-Mapping in my entity
{code:java}@Entity
public class MyEntity {
@Id
private Long id;
@JdbcTypeCode(SqlTypes.JSON)
private MyJson jsonProperty;
private String info;
}{code}
MyJson is a simple POJO:
{code:java}@Embeddable
public class MyJson {
private String stringProp;
private Long longProp;
}{code}
If i change only the jsonProperty, it seems the entity is _not marked dirty_ → changes are
not written to the DB.
If i change any other field-value to (in my test-case the String-field _info_), the entity
is marked dirty and all changes are written to DB, even the JSON-changes.
(see _MyEntityTest.java_ in attached Test-project):
{code:java}@QuarkusTest
@Transactional(Transactional.TxType.REQUIRES_NEW)
class MyEntityTest {
@Inject
EntityManager em;
static final long PK = 123L;
static final String CHANGED = "CHANGED";
@Test
void shouldCreateUpdateAndSelectMyEntity() throws Exception {
insert();
findAndUpdate();
selectFiltered();
}
void insert() {
MyEntity myEntity = new MyEntity();
myEntity.setId(PK);
MyJson myJson = new MyJson();
myJson.setLongProp(100L);
myJson.setStringProp("Hello");
myEntity.setJsonProperty(myJson);
em.persist(myEntity);
}
void findAndUpdate() {
MyEntity found = em.find(MyEntity.class, PK);
found.getJsonProperty().setStringProp(CHANGED);
// found.setInfo(CHANGED); // by changing any other property of the entity, it will
be marked as dirty and EVERY change will be written to the DB
}
void selectFiltered() {
List<MyEntity> result = em
.createQuery("SELECT e FROM MyEntity e WHERE e.jsonProperty.longProp = :x",
MyEntity.class)
.setParameter("x", 100L)
.getResultList();
assertEquals(1, result.size());
assertEquals(CHANGED, result.get(0).getJsonProperty().getStringProp(), "json property
not changed");
assertEquals(CHANGED, result.get(0).getInfo(), "plain property not changed");
}
}{code}
