Problem
It seems like my SpringBoot application can't connect with ElasticSearch. I keep getting this error whenever i try to run my application:
UnsatisfiedDependencyException: Error creating bean with name 'filterController': Unsatisfied dependency expressed through field 'service': Error creating bean with name 'filterService': Unsatisfied dependency expressed through field 'repository': Error creating bean with name 'filterRepository' defined in repository.FilterRepository defined in @EnableElasticsearchRepositories declared on ElasticsearchRepositoriesRegistrar.EnableElasticsearchRepositoriesConfiguration: Failed to instantiate [org.springframework.data.elasticsearch.repository.support.SimpleElasticsearchRepository]: Constructor threw exception
Code info
- I didn't make any changes nor extra-configurations. I'm running ElasticSearch normally
- I did not create a custom configuration file, since SpringBoot does it automatically
- You can find full source-code here
This is my Application.java file:
package br.com.uburu.spring;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
This is my FilterController.java file:
package br.com.uburu.spring.controller;
// Imports
@RestController
@RequestMapping("/api/v1/filter")
public class FilterController {
@Autowired
private FilterService service;
@GetMapping
public ResponseEntity<List<Filter>> getAll() {
List<Filter> filters = service.getAll();
return new ResponseEntity<List<Filter>>(filters, HttpStatus.OK);
}
@GetMapping("/{id}")
public ResponseEntity<Filter> getById(@PathVariable("id") long id) {
Filter filter = service.findById(id);
return new ResponseEntity<Filter>(filter, HttpStatus.OK);
}
// Some other methods
}
This is the FilterService.java file:
package br.com.uburu.spring.service;
// Imports
@Service
public class FilterService {
@Autowired
private FilterRepository repository;
public List<Filter> getAll() {
List<Filter> filters = new ArrayList<>();
repository.findAll().forEach(filters::add);
return filters;
}
public Filter findById(long id) {
return repository.findById(id).orElse(null);
}
public Filter save(Filter filter) {
return repository.save(filter);
}
public void delete(long id) {
repository.deleteById(id);
}
}
My FilterRepository.java file:
package br.com.uburu.spring.repository;
import org.springframework.data.elasticsearch.repository.ElasticsearchRepository;
import br.com.uburu.spring.document.Filter;
public interface FilterRepository extends ElasticsearchRepository<Filter, Long> {}

Some solutions i've tried:
- Initializing my service and repository variables without the
@Autowiredtag - Initializing it inside a class constructor, passing the
@Autowiredtag above the constructor - Running ElasticSearch as admin
- Cleaning Java Language Server Workspace (I'm using VSCode)
- Running
mvn clean installonce again before trying to run my application
Logs from ElasticSearch
I've noticed this logs in the ElasticSearch's console whenever i try to run my SpringBoot application:
[2023-04-23T14:57:56,085][WARN ][o.e.h.n.Netty4HttpServerTransport] [DESKTOP-LO4MIAG] received plaintext http traffic on an https channel, closing connection Netty4HttpChannel{localAddress=/127.0.0.1:9200, remoteAddress=/127.0.0.1:53007}
