Spring Data Elasticsearch cusom repository - spring

Question

In my Spring Boot application I'm trying to implement a fuzzy search via Elasticsearch.
This is my ES config:
#Profile("test")
#Configuration
#EnableElasticsearchRepositories(basePackages = "com.example.domain.repository.elasticsearch")
public class ElasticsearchTestConfig {
}
I have a repository:
#Repository
public interface ESDecisionRepository extends ElasticsearchRepository<ESDecision, String>, ESDecisionRepositoryCustom {
}
In order to be able to do a fuzzy search I have created a custom repository:
public interface ESDecisionRepositoryCustom {
public List<ESDecision> findFuzzyBySearchTerm(String searchTerm);
}
and provided a custom implementation:
#Repository
public class ESDecisionRepositoryCustomImpl implements ESDecisionRepositoryCustom {
#Autowired
protected ElasticsearchTemplate elasticsearchTemplate;
#Override
public List<ESDecision> findFuzzyBySearchTerm(String searchTerm) {
Criteria c = new Criteria("name").fuzzy(searchTerm);
return elasticsearchTemplate.queryForList(new CriteriaQuery(c), ESDecision.class);
}
}
Right now during startup my application fails with a following exception:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ESDecisionRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.PropertyReferenceException: No property searchTerm found for type ESDecision!

What am I doing wrong and how to fix it ?

Answer 1

Change your custom repository implementation class name from ESDecisionRepositoryCustomImpl to ESDecisionRepositoryImpl.
From the docs
The most important bit for the class to be found is the Impl postfix of the name on it compared to the core repository interface (see below).
There is a naming convention that has to be followed to make the custom repository implementation work. Check out the docs
Try this:
#Repository
public class ESDecisionRepositoryCustomImpl implements ESDecisionRepositoryCustom {
#Autowired
protected ElasticsearchTemplate elasticsearchTemplate;
#Override
public List<ESDecision> findFuzzyBySearchTerm(String searchTerm) {
Criteria c = new Criteria("name").fuzzy(searchTerm);
return elasticsearchTemplate.queryForList(new CriteriaQuery(c), ESDecision.class);
}
}
Hope this helps.
