private final MapString, TokenCache localCache new ConcurrentHashMap(); public String getAccessToken(String corpId, String secret) { String cacheKey wecom:token: corpId; // 一级缓存本地内存5分钟过期 TokenCache local localCache.get(cacheKey); if (local ! null !local.isExpired()) { return local.getToken(); } // 二级缓存Redis分布式缓存110分钟过期 String redisToken redisTemplate.opsForValue().get(cacheKey); if (redisToken ! null) { localCache.put(cacheKey, new TokenCache(redisToken, 300)); return redisToken; } // 三级策略刷新Token并双写 String newToken refreshFromWeCom(corpId, secret); redisTemplate.opsForValue().set(cacheKey, newToken, Duration.ofMinutes(110)); localCache.put(cacheKey, new TokenCache(newToken, 300)); return newToken; } }请求限流与熔断基于Resilience4j实现的企业级限流策略Configuration public class WeComCircuitBreakerConfig { Bean public CircuitBreaker weComCircuitBreaker() { CircuitBreakerConfig config CircuitBreakerConfig.custom() .failureRateThreshold(50) .waitDurationInOpenState(Duration.ofSeconds(30)) .permittedNumberOfCallsInHalfOpenState(10) .slidingWindowSize(100) .build();

return RateLimiter.of(weComApi, config); } }异步处理与响应式编程rx-wecom-sdk模块提供了完整的响应式支持Service public class ReactiveWeComService { Autowired private ReactiveAgentApi agentApi; public MonoAgentDetailsResponse getAgentDetailsReactive(String agentId) { return agentApi.detail(agentId) .timeout(Duration.ofSeconds(10)) .retryWhen(Retry.backoff(3, Duration.ofSeconds(1))) .doOnError(error - log.error(获取应用详情失败, error)) .onErrorResume(e - Mono.just(AgentDetailsResponse.error(e.getMessage()))); } public FluxDepartment getDepartmentsReactive() { return departmentApi.list() .flatMapMany(response - Flux.fromIterable(response.getDepartments())) .buffer(10) // 批量处理 .delayElements(Duration.ofMillis(100)); // 控制请求频率 } } 场景化应用典型业务场景实战场景一大规模组织架构同步企业微信组织架构同步面临数据量大、关系复杂的问题Service public class OrgSyncService { Autowired private DepartmentApi departmentApi; Autowired private UserApi userApi; Transactional public SyncResult syncOrganization() { // 1. 批量获取部门支持分页 ListDepartment departments departmentApi.listAll(); // 2. 并行获取部门成员 ListCompletableFutureListUser futures departments.stream() .map(dept - CompletableFuture.supplyAsync( () - userApi.listByDepartment(dept.getId()), executorService )) .collect(Collectors.toList()); // 3. 数据合并与持久化 return CompletableFuture.allOf(futures.toArray(new CompletableFuture[0])) .thenApply(v - { ListUser allUsers futures.stream() .map(CompletableFuture::join) .flatMap(List::stream) .collect(Collectors.toList()); return persistOrganization(departments, allUsers); }) .join(); } }场景二客户关系管理CRM集成外部联系人管理是企业微信的核心功能Service public class ExternalContactService { Autowired private ExternalContactManager externalContactManager; public CustomerJourney trackCustomerJourney(String externalUserId) { // 1. 获取客户详情 ExternalContactUser user externalContactManager.get(externalUserId); // 2. 获取跟进人列表 ListFollowUser followers externalContactManager.listFollowers(externalUserId); // 3. 获取互动记录 ListInteractionRecord interactions externalContactManager .getInteractionRecords(externalUserId, LocalDateTime.now().minusDays(30), LocalDateTime.now()); // 4. 构建客户旅程 return CustomerJourney.builder() .customer(user) .followers(followers) .interactions(interactions) .lastActiveTime(getLastActiveTime(interactions)) .build(); } }场景三审批流程自动化企业微信审批API的深度集成Service public class ApprovalWorkflowService { Autowired private ApprovalApi approvalApi; Transactional public ApprovalResult submitComplexApproval(ComplexApprovalRequest request) { // 1. 构建审批数据 ApprovalApplyRequest applyRequest ApprovalApplyRequest.builder() .creatorUserId(request.getApplicant()) .templateId(request.getTemplateId()) .applyData(buildApplyData(request)) .summary(buildSummary(request)) .build(); // 2. 提交审批 ApprovalSpNo spNo approvalApi.apply(applyRequest); // 3. 异步监听审批状态 CompletableFuture.runAsync(() - { monitorApprovalStatus(spNo.getSpNo(), request.getCallbackUrl()); }); return ApprovalResult.success(spNo); } private void monitorApprovalStatus(String spNo, String callbackUrl) { // Webhook回调监听 approvalApi.registerCallback(callbackUrl); // 轮询状态生产环境建议使用消息队列 ScheduledExecutorService scheduler Executors.newSingleThreadScheduledExecutor(); scheduler.scheduleAtFixedRate(() - { ApprovalDetail detail approvalApi.getDetail(spNo); if (detail.getStatus().isFinal()) { processApprovalResult(detail); scheduler.shutdown(); } }, 0, 30, TimeUnit.SECONDS);
