我使用Spring集成了MongoDB,我的数据服务有一个自动安装的mongo存储库,一切正常.除非在启动期间db已关闭.
当服务启动时mongo关闭时,初始化期间会抛出异常,在这种情况下,整个服务无法启动.这显然不是我想要的.
我想要发生的是捕获异常并启动服务,并优雅地处理数据库可用性问题(比如显示一个页面说我们有临时问题,使用缓存或其他)
我的存储库类：
public interface MediaDataRepository extends MongoRepository
我的服务类：
@Servicepublic class MediaDataService { @Autowired private MediaDataRepository mediaDataRepository;...}
和控制器：
@Controller@RequestMapping("/api/consumer")public class MediaController extends HtmlGenerationController { private static final Logger LOG = LoggerFactory.getLogger(MediaController.class); @Autowired private MediaDataService mediaDataService;...}
我在启动时得到的错误：

最佳答案
在我的搜索中,我发现没有好的方法让Spring直接处理它.您可能需要在服务和存储库之间放置代理.这里的帖子：How to make App server to start even if database is down?接近这个问题.
对你来说,这可能意味着拥有Spring创建的bean(RepositoryProxy).这个bean将尝试手动创建Mongo连接,或者从应用程序上下文的lazy bean中获取存储库.如果Mongo连接失败,它将捕获异常并为缓存数据或错误响应创建连接/对象.它还可以创建一个计时器进程来重新连接到Mongo实例.
