SpringBoot无法连接ElasticSearch，SimpleElasticsearchRepository实例化失败

我的SpringBoot应用无法与ElasticSearch建立连接，启动时持续抛出以下错误：

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

代码相关信息 #

• 未做任何额外配置，ElasticSearch正常运行
• 未创建自定义配置文件，依赖SpringBoot自动完成配置
• 完整源码可查看对应代码仓库的elasticsearch分支

Application.java文件 #

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);
    }

}

FilterController.java文件 #

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
    
}

FilterService.java文件 #

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);
    }
    
}

FilterRepository.java文件 #

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> {}

已尝试的解决方案 #

• 移除@Autowired注解初始化service和repository变量
• 通过构造函数注入，将@Autowired注解放在构造函数上
• 以管理员身份运行ElasticSearch
• 清理VSCode的Java Language Server工作区
• 运行mvn clean install后再启动应用

ElasticSearch日志信息 #

启动SpringBoot应用时，ElasticSearch控制台出现以下日志：

[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}
