User

import org.springframework.data.annotation.Id;
import org.springframework.data.elasticsearch.annotations.Document;

@Document(indexName = "user", type = "user", shards = 1, replicas = 0, refreshInterval = "-1")
public class User {
  @Id
  private String id;
  private String name;
  private int age;

UserRepository

public interface UserRepository extends ElasticsearchRepository 

UserServiceImpl

@Service
public class UserServiceImpl implements UserService {
  @Autowired
  private UserRepository userRepository;

  @Override
  public void save(User user) {
    userRepository.save(user);
  }

  @Override
  public Iterable findAll() {
    return userRepository.findAll();
  }

}

UserController

@RestController
@RequestMapping(value = "/es/")
public class UserController {
  @Autowired
  private UserService userService;

  @RequestMapping("/list")
  public Iterable list() {
    userService.save(new User("je_ge", 33));
    return userService.findAll();
  }
}

访问流程

• 启动Application
• 访问http://localhost:8080/es/list
• 输出

{"content":[{"id":"AVnQx4i3pXUZjTYvVwwS","name":"je_ge","age":33}],"totalElements":1,"totalPages":1,"last":true,"number":0,"size":1,"sort":null,"numberOfElements":1,"first":true}
