测试策略

单元测试示例

@ExtendWith(MockitoExtension.class)class IntelligentCustomerServiceTest { @Mock private AnthropicChatModel chatModel; @Mock private VectorStore vectorStore; @Mock private ChatMemory chatMemory; @Mock private ConversationService conversationService; @InjectMocks private IntelligentCustomerService customerService; @Test void shouldHandleUserQuerySuccessfully() { // Given ChatRequest request = ChatRequest.builder() .userId(\"user123\") .message(\"如何申请年假？\") .conversationId(\"conv456\") .build(); List<Document> mockDocs = Arrays.asList( new Document(\"年假申请需要提前2周提交申请表...\") ); when(vectorStore.similaritySearch(any(SearchRequest.class))) .thenReturn(mockDocs); when(chatMemory.get(eq(\"user123\"), eq(10))) .thenReturn(Arrays.asList()); org.springframework.ai.chat.model.ChatResponse mockResponse =  new org.springframework.ai.chat.model.ChatResponse(  Arrays.asList(new Generation(new AssistantMessage(\"根据公司政策，年假申请需要...\")))); when(chatModel.call(any(Prompt.class))) .thenReturn(mockResponse); // When ChatResponse response = customerService.handleUserQuery(request); // Then assertThat(response).isNotNull(); assertThat(response.getMessage()).contains(\"年假申请\"); assertThat(response.isError()).isFalse(); verify(vectorStore).similaritySearch(any(SearchRequest.class)); verify(chatModel).call(any(Prompt.class)); verify(chatMemory, times(2)).add(eq(\"user123\"), any(Message.class)); } @Test void shouldHandleEmptyKnowledgeBase() { // Given ChatRequest request = ChatRequest.builder() .userId(\"user123\") .message(\"这是一个新问题\") .build(); when(vectorStore.similaritySearch(any(SearchRequest.class))) .thenReturn(Arrays.asList()); // When & Then ChatResponse response = customerService.handleUserQuery(request); assertThat(response).isNotNull(); // 验证系统能够优雅处理空知识库的情况 }}

集成测试

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)@Testcontainersclass CustomerServiceIntegrationTest { @Container static PostgreSQLContainer<?> postgres = new PostgreSQLContainer<>(\"pgvector/pgvector:pg16\") .withDatabaseName(\"test_customer_service\") .withUsername(\"test\") .withPassword(\"test\"); @Autowired private TestRestTemplate restTemplate; @Autowired private KnowledgeBaseService knowledgeBaseService; @MockBean private AnthropicChatModel chatModel; @Test void shouldCompleteFullChatFlow() throws Exception { // 1. 准备测试数据 - 添加知识文档 MockMultipartFile testFile = new MockMultipartFile( \"file\",  \"test-doc.txt\",  \"text/plain\",  \"这是一个测试文档，包含公司政策信息。\".getBytes() ); knowledgeBaseService.addDocument(testFile, \"policy\", \"test-user\"); // 2. 模拟Claude响应 org.springframework.ai.chat.model.ChatResponse mockResponse =  new org.springframework.ai.chat.model.ChatResponse(  Arrays.asList(new Generation(new AssistantMessage(\"基于提供的文档，我可以回答您的问题...\")))); when(chatModel.call(any(Prompt.class))).thenReturn(mockResponse); // 3. 发送聊天请求 ChatRequest chatRequest = ChatRequest.builder() .message(\"请告诉我公司政策\") .userId(\"test-user\") .conversationId(\"test-conv\") .build(); HttpHeaders headers = new HttpHeaders(); headers.set(\"X-User-ID\", \"test-user\"); HttpEntity<ChatRequest> request = new HttpEntity<>(chatRequest, headers); // 4. 验证响应 ResponseEntity<ApiResponse> response = restTemplate.postForEntity( \"/api/chat/message\",  request,  ApiResponse.class ); assertThat(response.getStatusCode()).isEqualTo(HttpStatus.OK); assertThat(response.getBody().isSuccess()).isTrue(); }}

性能调优与扩展

1. 缓存优化

@Configuration@EnableCachingpublic class CacheConfig { @Bean public CacheManager cacheManager() { RedisCacheManager.Builder builder = RedisCacheManager .RedisCacheManagerBuilder .fromConnectionFactory(redisConnectionFactory()) .cacheDefaults(cacheConfiguration()); return builder.build(); } private RedisCacheConfiguration cacheConfiguration() { return RedisCacheConfiguration.defaultCacheConfig() .entryTtl(Duration.ofMinutes(30)) .serializeKeysWith(RedisSerializationContext.SerializationPair .fromSerializer(new StringRedisSerializer())) .serializeValuesWith(RedisSerializationContext.SerializationPair .fromSerializer(new GenericJackson2JsonRedisSerializer())); }}@Servicepublic class CachedKnowledgeService { @Cacheable(value = \"knowledge-search\", key = \"#query + \'-\' + #limit\") public List<KnowledgeSearchResult> searchWithCache(String query, int limit) { return knowledgeBaseService.searchKnowledge(query, limit); } @CacheEvict(value = \"knowledge-search\", allEntries = true) public void clearSearchCache() { // 当知识库更新时清除缓存 }}

2. 异步处理优化

@Configuration@EnableAsyncpublic class AsyncConfig { @Bean(name = \"documentProcessingExecutor\") public TaskExecutor documentProcessingExecutor() { ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor(); executor.setCorePoolSize(4); executor.setMaxPoolSize(8); executor.setQueueCapacity(100); executor.setThreadNamePrefix(\"doc-processing-\"); executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy()); executor.initialize(); return executor; } @Bean(name = \"chatProcessingExecutor\") public TaskExecutor chatProcessingExecutor() { ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor(); executor.setCorePoolSize(8); executor.setMaxPoolSize(16); executor.setQueueCapacity(200); executor.setThreadNamePrefix(\"chat-processing-\"); executor.initialize(); return executor; }}@Servicepublic class AsyncDocumentProcessor { @Async(\"documentProcessingExecutor\") public CompletableFuture<Void> processDocumentAsync(MultipartFile file,  String category,  String uploadedBy) { try { knowledgeBaseService.addDocument(file, category, uploadedBy); // 发送处理完成通知 notificationService.sendProcessingComplete(uploadedBy, file.getOriginalFilename()); return CompletableFuture.completedFuture(null);  } catch (Exception e) { log.error(\"异步文档处理失败\", e); notificationService.sendProcessingError(uploadedBy, file.getOriginalFilename(), e.getMessage()); throw new CompletionException(e); } }}

3. 流式响应实现

@RestControllerpublic class StreamingChatController { @GetMapping(value = \"/api/chat/stream\", produces = MediaType.TEXT_EVENT_STREAM_VALUE) public Flux<ServerSentEvent<String>> streamChat( @RequestParam String message, @RequestParam String userId) { return Flux.create(sink -> { try { // 构建流式请求 ChatRequest request = ChatRequest.builder() .message(message) .userId(userId) .build(); // 调用支持流式响应的服务 customerService.handleUserQueryStream(request) .subscribe( chunk -> sink.next( ServerSentEvent.<String>builder()  .data(chunk)  .build() ), error -> sink.error(error), () -> sink.complete() );  } catch (Exception e) { sink.error(e); } }); }}
