存储库

@Repository
public interface StudentRepository extends ElasticsearchRepository<Student, Integer>{}

控制器

@RestController
public class Controller {
    
    @Autowired
    StudentRepository studentRepo;
    
    @GetMapping(value="/student/all")
    List<Student> getAllStudent() {
        
        Iterator<Student> studentList = studentRepo.findAll().iterator();
        List<Student> students = new ArrayList<>();
        if(studentList.hasNext()) {
            students.add(studentList.next());

考虑在您的配置中定义一个名为"elasticsearchTemplate"的bean.

Consider defining a bean named 'elasticsearchTemplate' in your configuration.

推荐答案

您需要在application.properties文件中定义一些弹性搜索属性，例如 cluster-nodes ， cluster-names，由 ElasticsearchTemplate 和 ElasticsearchRepository 使用以连接到Elasticsearch引擎.

You need to define some elastic search properties in your application.properties file such as cluster-nodes, cluster-names which are used by ElasticsearchTemplate and ElasticsearchRepository to connect to the Elasticsearch engine.
