Untuk menghasilkan semula masalah, lihat kod di bawah untuk melihat sama ada terdapat masalah dan cara menyelesaikannya:
@RequestMapping("verify") @RestController @DependsOn({"DingAppInfoService","CloudChatAppInfoService"}) public class LoginAction { @Qualifier("ElderSonService") @Autowired private ElderSonService elderSonService; @Qualifier("EmployeeService") @Autowired private EmployeeService employeeService; @Qualifier("UserThreadPoolTaskExecutor") @Autowired private ThreadPoolTaskExecutor userThreadPoolTaskExecutor; private static AuthRequest ding_request = null; private static RongCloud cloud_chat = null; private static TokenResult register = null; private static final ThreadLocal<String> USER_TYPE = new ThreadLocal<>(); /** * 注意不能在bean的生命周期方法上添注@CheckAppContext注解 */ @PostConstruct public void beforeVerifySetContext() { AppContext.fillLoginContext(); Assert.hasText(AppContext.getAppLoginDingId(), "初始化app_login_ding_id错误"); Assert.hasText(AppContext.getAppLoginDingSecret(), "初始化app_login_ding_secret错误"); Assert.hasText(AppContext.getAppLoginReturnUrl(), "初始化app_login_return_url错误"); Assert.hasText(AppContext.getCloudChatKey(), "初始化cloud_chat_key错误"); Assert.hasText(AppContext.getCloudChatSecret(), "初始化cloud_chat_secret错误"); if (!(StringUtils.hasText(AppContext.getCloudNetUri()) || StringUtils.hasText(AppContext.getCloudNetUriReserve()))) { throw new IllegalArgumentException("初始化cloud_net_uri与cloud_net_uri_reserve错误"); } ding_request = new AuthDingTalkRequest( AuthConfig.builder(). clientId(AppContext.getAppLoginDingId()). clientSecret(AppContext.getAppLoginDingSecret()). redirectUri(AppContext.getAppLoginReturnUrl()).build()); cloud_chat = RongCloud.getInstance(AppContext.getCloudChatKey(), AppContext.getCloudChatSecret()); } .....以下API方法无所影响...... }
Apa yang mungkin membingungkan ialah kod kaedah permulaan dalam komponen pengawal :
public static void fillLoginContext() { DingAppInfo appInfo = SpringContextHolder.getBean(DingAppInfoService.class).findAppInfo(APP_CODE); setDingVerifyInfo(appInfo); CloudChatAppInfo cloudChatAppInfo = SpringContextHolder.getBean(CloudChatAppInfoService.class).findAppInfo(APP_CODE); setCloudChatInfo(cloudChatAppInfo); } public static void setDingVerifyInfo(DingAppInfo dingAppInfo){ if (dingAppInfo.checkKeyWordIsNotNull(dingAppInfo)) { put(APP_LOGIN_DING_ID, dingAppInfo.getApp_id()); put(APP_LOGIN_DING_SECRET, dingAppInfo.getApp_secret()); put(APP_LOGIN_RETURN_URL, dingAppInfo.getApp_return_url()); } } public static void setCloudChatInfo(CloudChatAppInfo cloudChatAppInfo){ if (cloudChatAppInfo.checkKeyWordIsNotNull(cloudChatAppInfo)){ put(CLOUD_CHAT_KEY,cloudChatAppInfo.getCloud_key()); put(CLOUD_CHAT_SECRET,cloudChatAppInfo.getCloud_secret()); put(CLOUD_NET_URI,cloudChatAppInfo.getCloud_net_uri()); put(CLOUD_NET_URI_RESERVE,cloudChatAppInfo.getCloud_net_uri_reserve()); } }
Di sini anda boleh mendapati bahawa sesetengah data tersuai projek sebenarnya dituangkan ke dalam utas tempatan ThreadLocal
Idea penyelesaian (sebenarnya ini bukan penyelesaian, tetapi ia juga boleh dilakukan dengan kos prestasi tinggi):
Reka bentuk pendengar dan penerbit dalam kaedah kemasukan permintaan Laksanakan aspek pemprosesan. Aspek menyemak data objek AppContext Jika ia kosong, acara akan diterbitkan Jika ia tidak kosong, masukkan kaedah:
Prototaip acara:
public class AppContextStatusEvent extends ApplicationEvent { public AppContextStatusEvent(Object source) { super(source); } public AppContextStatusEvent(Object source, Clock clock) { super(source, clock); } }
