.claim("username", username)
.issuedAt(new Date())
.expiration(new Date(System.currentTimeMillis() + 86400000))
.signWith(secretKey)
.compact();
}
}
```
### 2.3 异步处理优化

public class AsyncConfig implements AsyncConfigurer {
@Override
public Executor getAsyncExecutor() {
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
executor.setCorePoolSize(20);
executor.setMaxPoolSize(100);
executor.setQueueCapacity(500);
executor.setKeepAliveSeconds(60);
executor.setThreadNamePrefix("emotion-async-");
executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
executor.initialize();
return executor;
}
@Bean("aiTaskExecutor")
public Executor aiTaskExecutor() {
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
executor.setCorePoolSize(10);
executor.setMaxPoolSize(50);
executor.setQueueCapacity(200);
executor.setThreadNamePrefix("ai-task-");
executor.initialize();
return executor;
}
}
```
### 2.4 HTTP客户端配置
#### 2.4.1 WebClient配置
```java
@Configuration
public class WebClientConfig {
@Bean
public WebClient.Builder webClientBuilder() {
return WebClient.builder()
.codecs(configurer -> configurer.defaultCodecs().maxInMemorySize(10 * 1024 * 1024))
.filter(ExchangeFilterFunction.ofRequestProcessor(clientRequest -> {
log.debug("Request: {} {}", clientRequest.method(), clientRequest.url());
return Mono.just(clientRequest);
}))
.filter(ExchangeFilterFunction.ofResponseProcessor(clientResponse -> {
log.debug("Response: {}", clientResponse.statusCode());
return Mono.just(clientResponse);
}));
}
@Bean
public RestTemplate restTemplate() {
RestTemplate restTemplate = new RestTemplate();
// 设置超时时间
SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
factory.setConnectTimeout(30000);
factory.setReadTimeout(30000);
restTemplate.setRequestFactory(factory);
// 添加请求拦截器
restTemplate.getInterceptors().add(new ClientHttpRequestInterceptor() {
@Override
public ClientHttpResponse intercept(HttpRequest request, byte[] body, ClientHttpRequestExecution execution) throws IOException {
log.debug("Request: {} {}", request.getMethod(), request.getURI());
ClientHttpResponse response = execution.execute(request, body);
log.debug("Response: {}", response.getStatusCode());
return response;
}
});
return restTemplate;
}
}
```
### 2.5 缓存优化
#### 2.5.1 Redis配置升级
```java
@Configuration
@EnableCaching
public class RedisConfig {
@Bean
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
RedisTemplate<String, Object> template = new RedisTemplate<>();
template.setConnectionFactory(factory);
Jackson2JsonRedisSerializer<Object> serializer = new Jackson2JsonRedisSerializer<>(Object.class);
ObjectMapper mapper = new ObjectMapper();
mapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
mapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance,
ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As.PROPERTY);
mapper.registerModule(new JavaTimeModule());
serializer.setObjectMapper(mapper);
template.setKeySerializer(new StringRedisSerializer());
template.setValueSerializer(serializer);
template.afterPropertiesSet();
return template;
}
@Bean
public CacheManager cacheManager(RedisConnectionFactory factory) {
RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
.entryTtl(Duration.ofMinutes(30))
.serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(new StringRedisSerializer()))
.serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(new GenericJackson2JsonRedisSerializer()));
return RedisCacheManager.builder(factory)
.cacheDefaults(config)
.build();
}
}
```
## 3. 配置管理优化
### 3.1 多环境配置
```yaml
# application.yml (主配置)
spring:
profiles:
active: ${SPRING_PROFILES_ACTIVE:local}
application:
name: emotion-museum
jackson:
date-format: yyyy-MM-dd HH:mm:ss
time-zone: GMT+8
serialization:
write-dates-as-timestamps: false
default-property-inclusion: non_null
# application-local.yml (本地环境)

data:
redis:
host: localhost
port: 6379
password:
# application-prod.yml (生产环境)
server:
port: 19089
servlet:
context-path: /api
spring:
datasource:
url: jdbc:mysql://prod-db:3306/emotion_museum_prod
username: ${MYSQL_USERNAME}
password: ${MYSQL_PASSWORD}
data:
redis:
host: ${REDIS_HOST}
port: ${REDIS_PORT}
password: ${REDIS_PASSWORD}
# Coze API配置
emotion:

api-key: ${COZE_API_KEY}
bot-id: ${COZE_BOT_ID}
base-url: https://www.coze.cn/api
timeout: 30000
max-retries: 3
```
### 3.2 数据库连接池优化
```yaml
spring:
datasource:
hikari:
maximum-pool-size: 30
minimum-idle: 10
connection-timeout: 30000
idle-timeout: 600000
max-lifetime: 1800000
leak-detection-threshold: 60000
connection-test-query: SELECT 1
```
## 4. API文档升级
### 4.1 SpringDoc OpenAPI 3配置
```java
@Configuration
public class OpenApiConfig {
@Bean
public OpenAPI customOpenAPI() {
return new OpenAPI()
.info(new Info()
.title("情绪博物馆API文档")
.version("1.0.0")
.description("情绪博物馆后端服务API文档")
.contact(new Contact()
.name("情绪博物馆团队")
.email("support@emotion-museum.com")))
.addSecurityItem(new SecurityRequirement().addList("Bearer Authentication"))
.components(new Components()
.addSecuritySchemes("Bearer Authentication",
new SecurityScheme()
.type(SecurityScheme.Type.HTTP)
.scheme("bearer")
.bearerFormat("JWT")));
}
}
```
### 4.2 控制器文档注解
```java
@RestController
@RequestMapping("/auth")
@Tag(name = "认证管理", description = "用户认证相关接口")
public class AuthController {
@PostMapping("/login")
@Operation(summary = "用户登录", description = "用户登录接口")
@ApiResponses(value = {
@ApiResponse(responseCode = "200", description = "登录成功"),
@ApiResponse(responseCode = "400", description = "参数错误"),
@ApiResponse(responseCode = "401", description = "认证失败")
})
public Result<AuthResponse> login(@Valid @RequestBody LoginRequest request) {
AuthResponse response = authService.login(request);
return Result.success("登录成功", response);
}
}
```
## 5. 监控和日志优化
### 5.1 应用监控配置
```yaml
management:
endpoints:
web:
exposure:
include: health,info,metrics,prometheus
endpoint:
health:
show-details: always
metrics:
enabled: true
metrics:
export:
prometheus:
enabled: true
```
### 5.2 健康检查配置
```java
@Component
public class CustomHealthIndicator implements HealthIndicator {
@Autowired
private RedisTemplate<String, Object> redisTemplate;
@Autowired
private DataSource dataSource;
@Override
public Health health() {
try {
// 检查Redis连接
redisTemplate.opsForValue().get("health_check");
// 检查数据库连接
try (Connection connection = dataSource.getConnection()) {
try (Statement statement = connection.createStatement()) {
statement.execute("SELECT 1");
}
}
return Health.up()
.withDetail("redis", "UP")
.withDetail("database", "UP")
.build();
} catch (Exception e) {
return Health.down()
.withDetail("error", e.getMessage())
.build();
}
}
}
```
## 6. 性能优化方案
### 6.1 多级缓存设计
```java
@Service
public class UserService {
@Autowired
private UserMapper userMapper;
@Autowired
private RedisTemplate<String, Object> redisTemplate;
@Cacheable(value = "user", key = "#userId")
public User getUserById(String userId) {
return userMapper.selectById(userId);
}
@CacheEvict(value = "user", key = "#user.id")
public void updateUser(User user) {
userMapper.updateById(user);
}
@CacheEvict(value = "user", key = "#userId")
public void deleteUser(String userId) {
userMapper.deleteById(userId);
}
}
```
### 6.2 Coze API调用实现
#### 6.2.1 Coze配置类
```java
@Configuration
@ConfigurationProperties(prefix = "emotion.coze")
@Data
public class CozeConfig {
private String apiKey;
private String botId;
private String baseUrl = "https://www.coze.cn/api";
private int timeout = 30000;
private int maxRetries = 3;
// 验证配置
@PostConstruct
public void validateConfig() {
if (StringUtils.isEmpty(apiKey)) {
throw new IllegalStateException("Coze API Key不能为空");
}
if (StringUtils.isEmpty(botId)) {
throw new IllegalStateException("Coze Bot ID不能为空");
}
log.info("Coze配置验证通过，Bot ID: {}", botId);
}
}
```
#### 6.2.2 Coze客户端实现 (使用WebClient)
```java
@Service
@Slf4j
public class CozeClient {
@Autowired
private CozeConfig cozeConfig;
@Autowired
private WebClient.Builder webClientBuilder;
private final WebClient webClient;
public CozeClient(CozeConfig cozeConfig, WebClient.Builder webClientBuilder) {
this.cozeConfig = cozeConfig;
this.webClientBuilder = webClientBuilder;
this.webClient = webClientBuilder
.baseUrl(cozeConfig.getBaseUrl())
.defaultHeader("Authorization", "Bearer " + cozeConfig.getApiKey())
.defaultHeader("Content-Type", "application/json")
.codecs(configurer -> configurer.defaultCodecs().maxInMemorySize(10 * 1024 * 1024))
.build();
}
public Mono<String> sendMessage(String message, String conversationId) {
CozeRequest request = CozeRequest.builder()
.botId(cozeConfig.getBotId())
.message(message)
.conversationId(conversationId)
.build();
return webClient.post()
.uri("/chat/completions")
.bodyValue(request)
.retrieve()
.bodyToMono(CozeResponse.class)
.map(CozeResponse::getContent)
.timeout(Duration.ofMillis(cozeConfig.getTimeout()))
.retryWhen(Retry.backoff(cozeConfig.getMaxRetries(), Duration.ofSeconds(1)))
.doOnError(error -> log.error("Coze API调用失败: {}", error.getMessage()))
.doOnSuccess(response -> log.info("Coze API调用成功，响应长度: {}", response.length()));
}
public Mono<String> generateSummary(String conversationId) {
CozeSummaryRequest request = CozeSummaryRequest.builder()
.botId(cozeConfig.getBotId())
.conversationId(conversationId)
.build();
return webClient.post()
.uri("/chat/summary")
.bodyValue(request)
.retrieve()
.bodyToMono(CozeSummaryResponse.class)
.map(CozeSummaryResponse::getSummary)
.timeout(Duration.ofMillis(cozeConfig.getTimeout()))
.retryWhen(Retry.backoff(cozeConfig.getMaxRetries(), Duration.ofSeconds(1)));
}
}
```
#### 6.2.2.1 替代方案：使用RestTemplate (同步调用)
```java
@Service
@Slf4j
public class CozeRestTemplateClient {
@Autowired
private CozeConfig cozeConfig;
@Autowired
private RestTemplate restTemplate;
public String sendMessage(String message, String conversationId) {
CozeRequest request = CozeRequest.builder()
.botId(cozeConfig.getBotId())
.message(message)
.conversationId(conversationId)
.build();
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.setBearerAuth(cozeConfig.getApiKey());
HttpEntity<CozeRequest> entity = new HttpEntity<>(request, headers);
try {
ResponseEntity<CozeResponse> response = restTemplate.postForEntity(
cozeConfig.getBaseUrl() + "/chat/completions",
entity,
CozeResponse.class
);
if (response.getStatusCode() == HttpStatus.OK && response.getBody() != null) {
log.info("Coze API调用成功，响应长度: {}", response.getBody().getContent().length());
return response.getBody().getContent();
} else {
throw new RuntimeException("Coze API返回错误状态码: " + response.getStatusCode());
}
} catch (Exception e) {
log.error("Coze API调用失败: {}", e.getMessage());
throw new RuntimeException("Coze API调用失败", e);
}
}
public String generateSummary(String conversationId) {
CozeSummaryRequest request = CozeSummaryRequest.builder()
.botId(cozeConfig.getBotId())
.conversationId(conversationId)
.build();
HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON);
headers.setBearerAuth(cozeConfig.getApiKey());
HttpEntity<CozeSummaryRequest> entity = new HttpEntity<>(request, headers);
try {
ResponseEntity<CozeSummaryResponse> response = restTemplate.postForEntity(
cozeConfig.getBaseUrl() + "/chat/summary",
entity,
CozeSummaryResponse.class
);
if (response.getStatusCode() == HttpStatus.OK && response.getBody() != null) {
return response.getBody().getSummary();
} else {
throw new RuntimeException("Coze API返回错误状态码: " + response.getStatusCode());
}
} catch (Exception e) {
log.error("Coze API调用失败: {}", e.getMessage());
throw new RuntimeException("Coze API调用失败", e);
}
}
}
```
#### 6.2.3 AI服务异步化实现
```java
@Service
@Slf4j
public class AiChatService {
@Autowired
private CozeClient cozeClient; // 使用WebClient的异步客户端
@Autowired
private CozeRestTemplateClient cozeRestTemplateClient; // 使用RestTemplate的同步客户端
@Autowired
private MessageMapper messageMapper;
// 方案1：使用WebClient异步调用
@Async("aiTaskExecutor")
public CompletableFuture<String> sendChatMessageAsync(String conversationId, String message, String userId) {
try {
// 调用Coze API (异步方式)
String aiReply = cozeClient.sendMessage(message, conversationId)
.block(); // 在异步方法中阻塞等待结果
if (aiReply != null) {
// 异步保存消息
saveMessageAsync(conversationId, message, aiReply, userId);
return CompletableFuture.completedFuture(aiReply);
} else {
throw new RuntimeException("Coze API返回空响应");
}
} catch (Exception e) {
log.error("AI调用失败", e);
return CompletableFuture.failedFuture(e);
}
}
// 方案2：使用RestTemplate同步调用
@Async("aiTaskExecutor")
public CompletableFuture<String> sendChatMessageSyncAsync(String conversationId, String message, String userId) {
try {
// 调用Coze API (同步方式)
String aiReply = cozeRestTemplateClient.sendMessage(message, conversationId);
if (aiReply != null) {
// 异步保存消息
saveMessageAsync(conversationId, message, aiReply, userId);
return CompletableFuture.completedFuture(aiReply);
} else {
throw new RuntimeException("Coze API返回空响应");
}
} catch (Exception e) {
log.error("AI调用失败", e);
return CompletableFuture.failedFuture(e);
}
}
@Async("aiTaskExecutor")
public CompletableFuture<String> generateSummaryAsync(String conversationId) {
try {
String summary = cozeClient.generateSummary(conversationId)
.block();
return CompletableFuture.completedFuture(summary);
} catch (Exception e) {
log.error("生成对话总结失败", e);
return CompletableFuture.failedFuture(e);
}
}
@Async
public void saveMessageAsync(String conversationId, String userMessage, String aiReply, String userId) {
try {
// 异步保存用户消息
Message message = new Message();
message.setConversationId(conversationId);
message.setContent(userMessage);
message.setSenderId(userId);
message.setSenderType("USER");
message.setCreateTime(LocalDateTime.now());
messageMapper.insert(message);
// 异步保存AI回复
Message aiMessage = new Message();
aiMessage.setConversationId(conversationId);
aiMessage.setContent(aiReply);
aiMessage.setSenderId("AI");
aiMessage.setSenderType("AI");
aiMessage.setCreateTime(LocalDateTime.now());
messageMapper.insert(aiMessage);
log.info("消息保存成功，会话ID: {}", conversationId);
} catch (Exception e) {
log.error("保存消息失败", e);
}
}
}
```
#### 6.2.4 Coze请求响应DTO
```java
@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class CozeRequest {
private String botId;
private String message;
private String conversationId;
private Map<String, Object> parameters;
}
@Data

```java
@SpringBootTest
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
@Transactional
@Rollback
class UserServiceTest {
@Autowired
private UserService userService;
@MockBean
private UserMapper userMapper;
@Test
@DisplayName("测试用户注册")
void testUserRegistration() {
RegisterRequest request = new RegisterRequest();
request.setUsername("testuser");
request.setPassword("password123");
request.setEmail("test@example.com");
when(userMapper.selectByUsername("testuser")).thenReturn(null);
when(userMapper.insert(any(User.class))).thenReturn(1);
AuthResponse response = userService.register(request);
assertNotNull(response);
assertNotNull(response.getToken());
verify(userMapper).insert(any(User.class));
}
}
```
### 7.2 集成测试
