Java 尝试从spring应用程序向远程服务器上的mongodb发送数据时出错

我正在尝试创建一个网站，将连接到外部主机上的数据库。为此，我创建了两个虚拟机。一个包含MongoDB数据库，另一个包含在SpringBoot+react中创建的网站。我目前正处于创建RestController的阶段。我在尝试发送测试请求时出错：

2020-10-25 17:39:38.492 ERROR 25849 --- [nio-8080-exec-1] o.a.c.c.C.[.[.[/].[dispatcherServlet]    : Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.springframework.data.mongodb.UncategorizedMongoDbException: Exception authenticating MongoCredential{mechanism=SCRAM-SHA-1, userName='', source='', password=<hidden>, mechanismProperties=<hidden>}; nested exception is com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=SCRAM-SHA-1, userName='', source='', password=<hidden>, mechanismProperties=<hidden>}] with root cause

然而，这没有帮助

您可以在下面看到我的application.properties

spring.data.mongodb.authentication-database=
spring.data.mongodb.database=projectdb
spring.data.mongodb.field-naming-strategy=
spring.data.mongodb.grid-fs-database=
spring.data.mongodb.host=172.25.1.5
spring.data.mongodb.password=
spring.data.mongodb.port=27017
spring.data.mongodb.username=

下面是我的RestController，我不知道它是否有用，但我还是添加了它

@RestController
@CrossOrigin(origins = "http://localhost:3000")
public class VideoServiceController {

    @Autowired
    private IUserService iUserService;

    @Autowired
    private IRoleService iRoleService;


    @RequestMapping(value = "/postUser", method = RequestMethod.POST)
    @ResponseBody
    public void postUser(@ModelAttribute UserPOJO userPOJO) {


        iUserService.postUser(userPOJO);

    }

    @RequestMapping(value = "/getUsers", method = RequestMethod.GET)
    @ResponseBody
    public List<UserPOJO> getUsers() {


        return iUserService.getUserPojo();

    }

    @RequestMapping(value = "/getUsersById", method = RequestMethod.GET)
    @ResponseBody
    public UserPOJO getUsersById(@RequestParam("Id") String id) {


        return iUserService.getUserById(id);
    }

    @RequestMapping(value = "/getUserByEmailAndPass", method = RequestMethod.GET)
    @ResponseBody
    public UserPOJO getUserByEmailAndPass(@RequestParam("email") String email,
                                      @RequestParam("password") String password) {



        return iUserService.getUserByEmailAndPassword(email,password);

    }

    @RequestMapping(value = "/putPassword", method = RequestMethod.PUT)
    @ResponseBody
    public void putPassword(@RequestParam("id") String id,@RequestParam("newPass") String newPass,
                            @RequestParam("oldPass") String oldPass) {

        iUserService.putPassword(id,newPass,oldPass);

    }

    @RequestMapping(value = "/deleteUser", method = RequestMethod.DELETE)
    @ResponseBody
    public Boolean deleteUser(@RequestParam("id") String id) {

        return iUserService.deleteUser(id);

    }

    @RequestMapping(value = "/postRole", method = RequestMethod.POST)
    @ResponseBody
    public void postRole(@ModelAttribute RolePOJO role) {



        iRoleService.postRole(role);

    }

    @RequestMapping(value = "/getRoles", method = RequestMethod.GET)
    @ResponseBody
    public List<RolePOJO> getRoles() {



        return iRoleService.getRoles();

    }
    //5eca9ef4bf824a6544b732a5 USER
    @RequestMapping(value = "/deleteRole", method = RequestMethod.DELETE)
    @ResponseBody
    public Boolean deleteRole(@RequestParam("id") String id) {



        return iRoleService.deleteRole(id);

    }

    @RequestMapping(value = "/putUserRole", method = RequestMethod.PUT)
    @ResponseBody
    public void putUserRole(@RequestParam("userId") String userId, @RequestParam("roleName") String roleName) {

        iUserService.putUserRole(userId, roleName);


    }


}

与：

此错误开始出现（有更多错误，但所有其他错误都是由此错误引起的）：

我还添加了pom.xml文件

org.springframework.boot
不幸的是，它帮不了我。它提到添加数据库的名称，但我已经在评论中添加了它。一定是其他原因导致了此错误。
尝试使用文档中的以下配置类：

@Configuration
class ApplicationConfig extends AbstractMongoClientConfiguration {

  
  @Value("${spring.data.mongodb.uri}")
  public String mongoUri;

  @Override
  protected void configureClientSettings(MongoClientSettings.Builder builder) {
      builder.applyConnectionString(new ConnectionString(mongoUri));
  }

  @Override
  protected String getDatabaseName() {
    return "projectdb";
  }
}

这回答了你的问题吗？这可能也有帮助：@Aman和@AlexisG我已经检查了这些主题，但问题是没有给出数据库的名称。但是，我在这里提供了它：
spring.data.mongodb.database=projectdb
。在我添加这个之后：
spring.data.mongodb.uri=mongodb://172.25.1.5:27017/projectdb
错误已更改。我将在编辑中向主题添加错误。将uri替换为
mongodb://username:password@172.25.1.5:27017/projectdb
@Aman我没有用户或密码。首先我创建了它们，但当错误开始出现时，我删除了它们。我想看看这是否有帮助。不幸的是没有。同样的错误出现了这回答了你的问题吗？这可能也有帮助：@Aman和@AlexisG我已经检查了这些主题，但问题是没有给出数据库的名称。但是，我在这里提供了它：

@enablemongorepositions
。这导致spring停止查看我的存储库。对我来说也很有效。我明天将尝试它，并告诉它是否有用。它有效。我只需要删除
@enablemongorepositions
。这导致spring停止查看我的存储库，也为我工作
