## 三、响应式编程架构
### 3.1 响应式编程模型
本系统采用 Project Reactor 作为响应式编程库：
| 组件 | 类型 | 说明 |
|------|------|------|
| **Mono** | 0-1 个元素 | 表示异步计算结果，返回单个对象或空 |
| **Flux** | 0-N 个元素 | 表示异步数据流，返回多个对象 |
| **Scheduler** | 线程调度器 | 控制异步操作的执行线程 |
### 3.2 响应式编程规范
#### 3.2.1 基本原则
1. **永不阻塞**
- 禁止在响应式流中使用 `block()`、`blockFirst()`、`blockLast()`
- 所有 I/O 操作必须使用非阻塞方式
2. **链式调用**
- 使用 `flatMap`、`map`、`filter` 等操作符链式调用
- 避免嵌套的 `subscribe`
3. **错误处理**
- 使用 `onErrorResume`、`onErrorReturn` 处理错误
- 避免使用 `try-catch` 捕获响应式异常
4. **背压处理**
- 使用 `onBackpressureBuffer`、`onBackpressureDrop` 处理背压
- 避免内存溢出
#### 3.2.2 代码示例
**✅ 正确示例**：
```java
public Mono<Member> getMember(Long id) {
return memberRepository.findById(id)
.switchIfEmpty(Mono.error(new BusinessException("会员不存在")))
.flatMap(member -> loadMemberCards(member.getId()))
.flatMap(member -> loadMemberBenefits(member.getId()))
.doOnSuccess(member -> log.info("查询会员成功: memberId={}", member.getId()))
.doOnError(e -> log.error("查询会员失败: memberId={}", id, e));
}
```
**❌ 错误示例**：
```java
public Member getMember(Long id) {
// 错误：使用 block() 阻塞
return memberRepository.findById(id).block();
}
public Mono<Member> getMember(Long id) {
return memberRepository.findById(id)
.flatMap(member -> {
// 错误：在 flatMap 中使用 block()
List<MemberCard> cards = memberCardRepository.findByMemberId(member.getId()).collectList().block();
return Mono.just(member);
});
}
```
### 3.3 响应式事务管理
#### 3.3.1 本地事务
使用 `@Transactional` 注解管理本地事务：
```java
@Service
public class BookingService {
@Transactional
public Mono<BookingRecord> bookSlot(BookingRequest request) {
return validateBooking(request)
.flatMap(v -> checkSlotAvailability(request.getSlotId()))
.flatMap(slot -> deductBenefit(request.getMemberId(), slot))
.flatMap(benefit -> createBookingRecord(request, benefit))
.flatMap(booking -> updateSlotBookedCount(request.getSlotId()));
}
}
```
#### 3.3.2 分布式锁
使用 Redis 实现分布式锁：
```java
@Component
public class RedisDistributedLock {
private final ReactiveRedisTemplate<String, String> redisTemplate;
private static final String LOCK_PREFIX = "lock:";
private static final long DEFAULT_EXPIRE_TIME = 30;
public Mono<Boolean> tryLock(String key, long expireTime) {
String lockKey = LOCK_PREFIX + key;
String lockValue = UUID.randomUUID().toString();
return redisTemplate.opsForValue()
.setIfAbsent(lockKey, lockValue, Duration.ofSeconds(expireTime))
.flatMap(locked -> {
if (Boolean.TRUE.equals(locked)) {
log.info("获取锁成功: key={}", lockKey);
return Mono.just(true);
} else {
log.warn("获取锁失败: key={}", lockKey);
return Mono.just(false);
}
});
}
public Mono<Void> unlock(String key) {
String lockKey = LOCK_PREFIX + key;
return redisTemplate.delete(lockKey)
.doOnSuccess(deleted -> {
if (Boolean.TRUE.equals(deleted)) {
log.info("释放锁成功: key={}", lockKey);
}
})
.then();
}
}
```
#### 3.3.3 Saga 模式（跨模块事务）
对于跨模块的事务，使用 Saga 模式：
```java
@Service
public class BookingSaga {
public Mono<BookingRecord> execute(BookingRequest request) {
return bookSlot(request)
.flatMap(booking -> sendNotification(booking))
.flatMap(booking -> updateStatistics(booking))
.onErrorResume(e -> compensate(request, e));
}
private Mono<BookingRecord> bookSlot(BookingRequest request) {
// 预约逻辑
}
private Mono<BookingRecord> sendNotification(BookingRecord booking) {
// 发送通知
}
private Mono<BookingRecord> updateStatistics(BookingRecord booking) {
// 更新统计
}
private Mono<BookingRecord> compensate(BookingRequest request, Throwable e) {
// 补偿逻辑
}
}
```

### 5.3 日志管理
#### 5.3.1 日志配置
```yaml
logging:
level:
root: INFO
com.gym.manage: DEBUG
org.springframework.r2dbc: DEBUG
reactor.netty: INFO
file:
name: /app/logs/gym-manage.log
max-size: 100MB
max-history: 30
pattern:
console: "%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n"
file: "%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n"
```
#### 5.3.2 结构化日志
```java
@Slf4j
public class MemberService {
public Mono<Member> getMember(Long id) {
return memberRepository.findById(id)
.doOnSubscribe(s -> log.info("开始查询会员: memberId={}", id))
.doOnNext(m -> log.info("查询到会员: memberId={}, name={}", m.getId(), m.getName()))
.doOnError(e -> log.error("查询会员失败: memberId={}, error={}", id, e.getMessage()))
.doOnTerminate(() -> log.info("查询会员完成: memberId={}", id));
}
}
```

## 六、性能优化
### 6.1 数据库优化
#### 6.1.1 索引优化
```sql
-- 会员表索引
CREATE INDEX idx_member_tenant ON member(tenant_id) WHERE deleted_at IS NULL;
CREATE INDEX idx_member_store ON member(store_id) WHERE deleted_at IS NULL;
CREATE INDEX idx_member_phone ON member(phone) WHERE deleted_at IS NULL;
CREATE INDEX idx_member_level ON member(level) WHERE deleted_at IS NULL;
CREATE INDEX idx_member_status ON member(status) WHERE deleted_at IS NULL;
-- 预约记录表索引
CREATE INDEX idx_booking_member ON booking_record(member_id) WHERE deleted_at IS NULL;
CREATE INDEX idx_booking_slot ON booking_record(slot_id) WHERE deleted_at IS NULL;
CREATE INDEX idx_booking_coach ON booking_record(coach_id) WHERE deleted_at IS NULL;
CREATE INDEX idx_booking_status ON booking_record(status) WHERE deleted_at IS NULL;
CREATE INDEX idx_booking_time ON booking_record(created_at) WHERE deleted_at IS NULL;
```
#### 6.1.2 查询优化
```java
// ✅ 正确：使用索引
public Flux<Member> listMembers(Long tenantId, Long storeId) {
return memberRepository.findByTenantIdAndStoreId(tenantId, storeId);
}
// ❌ 错误：全表扫描
public Flux<Member> listMembers(Long tenantId, Long storeId) {
return memberRepository.findAll()
.filter(m -> m.getTenantId().equals(tenantId))
.filter(m -> m.getStoreId().equals(storeId));
}
```
### 6.2 缓存优化
#### 6.2.1 多级缓存
```java
@Service
public class MemberService {
private final MemberRepository memberRepository;
private final ReactiveRedisTemplate<String, Object> redisTemplate;
public Mono<Member> getMember(Long id) {
String cacheKey = "member:" + id;
return redisTemplate.opsForValue()
.get(cacheKey)
.cast(Member.class)
.switchIfEmpty(
memberRepository.findById(id)
.flatMap(member -> redisTemplate.opsForValue()
.set(cacheKey, member, Duration.ofMinutes(30))
.thenReturn(member))
);
}
}
```
#### 6.2.2 缓存策略
| 数据类型 | 缓存策略 | 过期时间 |
|---------|---------|---------|
| **会员信息** | Cache-Aside | 30 分钟 |
| **会员卡信息** | Cache-Aside | 1 小时 |
| **课程列表** | Cache-Aside | 10 分钟 |
| **预约时段** | Cache-Aside | 5 分钟 |
| **配置信息** | Write-Through | 1 小时 |
### 6.3 连接池优化
#### 6.3.1 R2DBC 连接池配置
```yaml
spring:
r2dbc:
pool:
initial-size: 5 # 初始连接数
max-size: 20 # 最大连接数
max-idle-time: 30m # 最大空闲时间
max-life-time: 1h # 最大生命周期
acquire-timeout: 5s # 获取连接超时时间
```
#### 6.3.2 Redis 连接池配置
```yaml
spring:
data:
redis:
lettuce:
pool:
max-active: 20 # 最大连接数
max-idle: 10 # 最大空闲连接数
min-idle: 5 # 最小空闲连接数
```
---
## 七、安全设计
### 7.1 认证授权
#### 7.1.1 JWT 认证
```java
@Configuration
@EnableWebFluxSecurity
public class SecurityConfig {
@Bean
public SecurityWebFilterChain securityWebFilterChain(
ServerHttpSecurity http,
JwtAuthenticationFilter jwtAuthenticationFilter) {
return http
.authorizeExchange(exchanges -> exchanges
.pathMatchers("/api/v1/auth/**").permitAll()
.pathMatchers("/actuator/**").permitAll()
.anyExchange().authenticated())
.addFilterBefore(jwtAuthenticationFilter, SecurityWebFiltersOrder.AUTHENTICATION)
.csrf(csrf -> csrf.disable())
.httpBasic(httpBasic -> httpBasic.disable())
.formLogin(formLogin -> formLogin.disable())
.build();
}
}
```
#### 7.1.2 数据加密
```java
@Component
public class EncryptionService {
private static final String AES_KEY = "your-secret-key";
private static final String AES_IV = "your-iv";
public String encrypt(String data) {
// AES 加密
}
public String decrypt(String encryptedData) {
// AES 解密
}
public String maskPhone(String phone) {
if (phone.length() == 11) {
return phone.substring(0, 3) + "****" + phone.substring(7);
}
return phone;
}
}
```
### 7.2 数据脱敏
```java
@Entity
public class Member {
@Column(name = "phone")
private String phone; // 加密存储
@Column(name = "phone_mask")
private String phoneMask; // 脱敏显示
@Column(name = "id_card")
private String idCard; // 加密存储
@Column(name = "emergency_phone")
private String emergencyPhone; // 加密存储
}
```
---
## 八、测试策略
### 8.1 单元测试
```java
@SpringBootTest
class MemberServiceTest {
@Autowired
private MemberService memberService;
@MockBean
private MemberRepository memberRepository;
@Test
void testGetMember() {
Member member = Member.builder()
.id(1L)
.name("张三")
.phone("13800138000")
.build();
when(memberRepository.findById(1L))
.thenReturn(Mono.just(member));
StepVerifier.create(memberService.getMember(1L))
.expectNextMatches(m -> m.getName().equals("张三"))
.verifyComplete();
}
}
```
### 8.2 集成测试
```java
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@AutoConfigureWebTestClient
class MemberControllerTest {
@Autowired
private WebTestClient webTestClient;
@Test
void testGetMember() {
webTestClient.get()
.uri("/api/v1/members/1")
.exchange()
.expectStatus().isOk()
.expectBody(Member.class)
.value(member -> {
assertThat(member.getName()).isEqualTo("张三");
});
}
}
```
### 8.3 性能测试
```java
@Test
void testGetMemberPerformance() {
StepVerifier.withVirtualTime(() -> memberService.getMember(1L))
.expectNextCount(1)
.expectComplete()
.verify(Duration.ofMillis(100));
}
```
