Question

我正在尝试在MongoDB中创建一个Users数据库，而ive却不了解如何创建数据库并将信息添加到DB的基本知识，但是当我运行该应用程序并检查是否在MongoDB Compass中建立了数据库时，我什么也没看到。我有0个代码错误，所以我不确定问题出在哪里。

任何对此的建议/帮助，将不胜感激。

实体；

@Document(collection = "Users")
public class User {

    @Id
    private String _firstname;

    @Indexed(direction = IndexDirection.ASCENDING)
    private String _surname;
    private String _email;
    private int _nhsid;
    private String _password;
    private Address _address;


    public User(String _firstname, String _surname, String _emaik, int _nhsid, String _password, Address _address) {
        this._firstname = _firstname;
        this._surname = _surname;
        this._email = _emaik;
        this._nhsid = _nhsid;
        this._password = _password;
        this._address = _address;
    }

   Getters / Setters


public class Address {

   private String _addressline;
   private String _postcode;
   private String _county;

   public Address(String _addressline, String _postcode, String _county) {
       this._addressline = _addressline;
       this._postcode = _postcode;
       this._county = _county;
   }

   Getters / Setters

用户存储库；

import org.springframework.data.mongodb.repository.MongoRepository;

public interface UserRepository extends MongoRepository<User, String> {
}

添加数据的测试类；

@Component
public class TestClass implements CommandLineRunner {

    private UserRepository userRepo;

    public TestClass(UserRepository userRepo) {
        this.userRepo = userRepo;
    }

    @Override
    public void run(String... args) throws Exception {
        User test1 = new User("XXXXXXX",
                "XXXXX",
                "FFFFFFFFFFFFFF",
                166673823,
                "Test123",
                new Address("5 Willet Lane", "XXXXXXXXXXXXX", "London"));

        User test2 = new User("Davneet",
                "Singh",
                "ManlikeDavs50@hotmail.co.uk",
                1664433333,
                "Test123",
                new Address("5 End Wills", "UB5 6JQ", "London"));

        this.userRepo.deleteAll();

        List<User> allUsers = Arrays.asList(test1,test2);
        this.userRepo.saveAll(allUsers);
    }

}

控制器;

@RestController
@RequestMapping("/Users")
public class accountServiceController {

    private UserRepository userRepo;

    public accountServiceController(UserRepository userRepo) {
        this.userRepo = userRepo;
    }

    @GetMapping("/getUsers")
    public List<User> getAllUsers(){
        List<User> users = this.userRepo.findAll();
        return users;
    }
}

应用程序属性；

spring.data.mongodb.host=localhost
spring.data.mongodb.port=27017
spring.data.mongodb.database=Users

我看不到告诉MongoDB在您提供的代码中创建Schema和表的配置。

请参考以下链接：Unable to get spring boot to automatically create database schema

Spring Boot应用程序未在MongoDB Compass中创建/显示数据库
