I am trying to query spring data elasticsearch repositories for nested properties. My Repository looks like this:
public interface PersonRepository extends
ElasticsearchRepository<Person, Long> {
List<Person> findByAddressZipCode(String zipCode);
}
The domain objects Person and Address (without getters/setters) are defined as follows:
@Document(indexName="person")
public class Person {
@Id
private Long id;
private String name;
@Field(type=FieldType.Nested, store=true, index = FieldIndex.analyzed)
private Address address;
}
public class Address {
private String zipCode;
}
My test saves one Person document and tries to read it with the repository method. But no results are returned. Here is the test method:
@Test
public void testPersonRepo() throws Exception {
Person person = new Person();
person.setName("Rene");
Address address = new Address();
address.setZipCode("30880");
person.setAddress(address);
personRepository.save(person);
elasticsearchTemplate.refresh(Person.class,true);
assertThat(personRepository.findByAddressZipCodeContaining("30880"), hasSize(1));
}
Does spring data elasticsearch support the default spring data query generation?
Elasticsearch indexes the new document asynchronously... near real-time . The default refresh is typically 1s I think. So you must explicitly request a refresh (to force a flush and the document available for search) if you are wanting the document immediately searchable as with a unit test. So your unit test needs to include the ElasticsearchTemplate bean so that you can explicitly call refresh . Make sure you set waitForOperation to true to force a synchronous refresh. See this related answer . Kinda like this:
elasticsearchTemplate.refresh("myindex",true);
