Anh cho em hỏi nếu muốn hiểu cái core với flow ezyfox của anh thì em nên đọc repo nào trước anh nhỉ, Kiểu trước kia em hay thắc mắc vì sao @Component annotation ở spring thì giúp mình đăng kí lớp đó như là bean để được quản lý ở bên dứoi á. Nay em thấy opensource của anh có những thứ đó. Nên em muốn dùng và nghiên cứu thêm thử. Với em thấy có cái gamebox cũng rất hay ạ.

So I watched the <a href="https://www.youtube.com/watch?v=aTZDSiiITBM&amp;list=PLlZavoxtKE1IfKY7ohkLLyv6YkHMkvH6G&amp;index=4">video</a> for the authentication with Ezyfox-server but I got an NullPointerException on UserRepo while I try to log in. I can't figure out why because I triple check my code and the video... <p> </p> <p> Here is my code: </p> <p> </p> <pre> # entity/BullyUser: @Getter @Setter @ToString @EzyCollection public class BullyUser { @EzyId int id; String username; String password; } # repo/BullyUserRepo: @EzyRepository("userRepo") public interface BullyUserRepo extends EzyMongoRepository&lt;Long, BullyUser&gt; { } # service/BullyUserService: public interface BullyUserService { void saveUser(BullyUser user); BullyUser createUser(String username, String password); BullyUser getUser(String username); } # service/impl/BullyUserServiceImpl: @Setter @EzySingleton("userService") public class BullyUserServiceImpl implements BullyUserService { @EzyAutoBind private BullyUserRepo BullyUserRepo; @Override public void saveUser(BullyUser user) { BullyUserRepo.save(user); } @Override public BullyUser createUser(String username, String password) { BullyUser user = new BullyUser(); user.setUsername(username); user.setPassword(password); BullyUserRepo.save(user); return user; } @Override public BullyUser getUser(String username) { return BullyUserRepo.findByField("username", username); } } // [PLUGIN]/controller/UserLoginController @EzySingleton @EzyEventHandler(USER_LOGIN) public class UserLoginController extends EzyAbstractPluginEventController { @EzyAutoBind private WelcomeService welcomeService; @EzyAutoBind private BullyUserService userService; @Override public void handle(EzyPluginContext ctx, EzyUserLoginEvent event) { logger.info("{} login in", welcomeService.welcome(event.getUsername())); String username = event.getUsername(); String password = event.getPassword(); BullyUser user = userService.getUser(username); if (user == null) { logger.info("User {} does not exist, creating new user", username); user = userService.createUser(username, password); userService.saveUser(user); } } } </pre>

Em đang viết test cho issue <a href="https://github.com/youngmonkeys/ezyfox-server/issues/68">https://github.com/youngmonkeys/ezyfox-server/issues/68</a>. Em dùng Mockito để khởi tạo EzyAppContext: <code class="markdown-inline">EzyAppContext appContext = mock(EzyAppContext.class)</code>. Nhưng làm vậy <code class="markdown-inline">context.get(ScheduledExecutorService.class)</code> trả về <code class="markdown-inline">null</code>: <p> </p> <img class="alignnone size-full wp-image-326" src="https://stackask.com/wp-content/uploads/2021/07/Screen-Shot-2021-07-30-at-16.52.13-1.png" alt="" /> <p> </p> <p> Cho em hỏi nên khởi tạo EzyAppContext như nào ạ? </p>

Em đã import ezyfox-server thành công, nhưng khi chạy thử <code>ezyfox-server/ezyfox-server-support/src/test/java/com/tvd12/ezyfoxserver/support/test/entry/EzySimpleAppEntryTest.java</code> thì bị exception, mặc dù test vẫn passed. Anh giải thích chỗ này giúp em với ạ. <p> </p> <p> Full log: </p> <pre>19:58:31,683 DEBUG [main] impl.EzyObjectWriterElementsFetcher - start scan class com.tvd12.ezyfoxserver.support.test.entry.ClientNoUserRequestHandler 19:58:31,695 DEBUG [main] impl.EzyObjectWriterElementsFetcher -
