Xử lý các vấn đề kết nối mongodb khi khởi động

Question

Tôi đã tích hợp MongoDB bằng Spring, dịch vụ dữ liệu của tôi có kho lưu trữ mongo tự động và tất cả đều hoạt động. Ngoại trừ khi db bị hỏng trong khi khởi động.

Khi mongo bị tắt trong khi dịch vụ xuất hiện, có một ngoại lệ được ném trong khi khởi tạo và trong trường hợp đó, toàn bộ dịch vụ không khởi động được. Đây không phải là điều tôi muốn rõ ràng.

Những gì tôi muốn xảy ra là để nắm bắt những ngoại lệ và bắt đầu dịch vụ, và xử lý các vấn đề db sẵn có một cách duyên dáng (như hiển thị một trang nói rằng chúng tôi đã có vấn đề tạm thời, sử dụng một bộ nhớ cache, hoặc bất cứ điều gì)

lớp kho của tôi:

public interface MediaDataRepository extends MongoRepository<MediaData, String> { 
... 
} 

dịch vụ My lớp:

@Service 
public class MediaDataService { 
    @Autowired 
    private MediaDataRepository mediaDataRepository; 
... 
} 

Và Bộ điều khiển:

@Controller 
@RequestMapping("/api/consumer") 
public class MediaController extends HtmlGenerationController { 
    private static final Logger LOG = LoggerFactory.getLogger(MediaController.class); 

    @Autowired 
    private MediaDataService mediaDataService; 
... 
} 

Các lỗi tôi nhận được trong quá trình khởi động:

Trong tìm kiếm của tôi, tôi thấy không có cách nào tốt để làm cho mùa xuân xử lý này trực tiếp. Bạn có thể cần phải đặt một proxy giữa dịch vụ của bạn và kho lưu trữ. Bài đăng ở đây: How to make App server to start even if database is down? tiếp cận vấn đề này.

Đối với bạn, điều này có thể có nghĩa là có một bean (RepositoryProxy) mà Spring tạo ra. Bean này sẽ cố gắng tạo kết nối Mongo theo cách thủ công, hoặc lấy kho từ bean lười của ngữ cảnh ứng dụng. Nếu kết nối Mongo không thành công, nó sẽ bắt ngoại lệ và tạo kết nối/đối tượng cho dữ liệu được lưu trong bộ nhớ cache hoặc các phản hồi lỗi. Nó cũng có thể tạo ra một quá trình hẹn giờ để kết nối lại với cá thể Mongo.
