    <dependencies>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-alibaba-dependencies</artifactId>
            <version>2022.0.0.0</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>2022.0.0</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

二、金融级核心模块实现

1. 账户服务(JPA + 分库分表)

// AccountServiceApplication.java
@SpringBootApplication
@EnableDiscoveryClient
@EnableJpaRepositories(basePackages = "com.finance.account.repository")
@EntityScan("com.finance.account.entity")
public class AccountServiceApplication {
    public static void main(String[] args) {
        SpringApplication.run(AccountServiceApplication.class, args);
    }
}

// 分库分表配置
@Configuration
public class ShardingConfig {
    
    @Bean
    public DataSource dataSource() throws SQLException {
        Map<String, DataSource> dataSourceMap = new HashMap<>();
        // 配置主库和从库
        dataSourceMap.put("master", masterDataSource());
        dataSourceMap.put("slave1", slaveDataSource1());
        
        // 分片规则
        ShardingRuleConfiguration shardingRuleConfig = new ShardingRuleConfiguration();
        shardingRuleConfig.getTableRuleConfigs().add(getAccountTableRule());
        
        // 分布式序列算法
        shardingRuleConfig.getBindingTableGroups().add("t_account");
        shardingRuleConfig.setDefaultDatabaseShardingStrategyConfig(
            new InlineShardingStrategyConfiguration("user_id", "master"));
        
        return ShardingDataSourceFactory.createDataSource(
            dataSourceMap, shardingRuleConfig, new Properties());
    }
    
    private TableRuleConfiguration getAccountTableRule() {
        TableRuleConfiguration result = new TableRuleConfiguration();
        result.setLogicTable("t_account");
        result.setActualDataNodes("master.t_account_${0..15}");
        result.setTableShardingStrategyConfig(
            new StandardShardingStrategyConfiguration(
                "account_no", 
                new PreciseModuloShardingAlgorithm()));
        return result;
    }
}

2. 支付服务(分布式事务 + 幂等设计)

// PaymentController.java
@RestController
@RequestMapping("/payment")
public class PaymentController {
    
    @Autowired
    private PaymentService paymentService;
    
    @PostMapping("/execute")
    @GlobalTransactional(timeoutMills = 60000, name = "finance-payment-tx")
    public Result<PaymentRecord> executePayment(
            @RequestBody PaymentRequest request,
            @RequestHeader("X-Idempotent-Key") String idempotentKey) {
        
        // 幂等校验
        if (paymentService.checkIdempotent(idempotentKey)) {
            return Result.success(paymentService.getByRequestId(idempotentKey));
        }
        
        // 执行支付
        PaymentRecord record = paymentService.executeTransaction(request);
        paymentService.saveIdempotentKey(idempotentKey, record.getId());
        
        return Result.success(record);
    }
}

// Seata 配置类
@Configuration
public class SeataConfig {
    
    @Bean
    public GlobalTransactionScanner globalTransactionScanner() {
        return new GlobalTransactionScanner(
            "payment-service", 
            "my_test_tx_group");
    }
}

三、金融风控系统实现

1. 实时风控网关过滤器

// RiskControlFilter.java
@Component
@Order(Ordered.HIGHEST_PRECEDENCE)
public class RiskControlFilter implements GlobalFilter {
    
    @Autowired
    private RiskEngine riskEngine;
    
    @Override
    public Mono<Void> filter(ServerWebExchange exchange, GatewayFilterChain chain) {
        ServerHttpRequest request = exchange.getRequest();
        
        // 1. 获取必要参数
        String clientIp = request.getRemoteAddress().getAddress().getHostAddress();
        String path = request.getPath().toString();
        String token = request.getHeaders().getFirst("Authorization");
        
        // 2. 构建风控上下文
        RiskContext context = RiskContext.builder()
            .clientIp(clientIp)
            .apiPath(path)
            .accessToken(token)
            .timestamp(System.currentTimeMillis())
            .build();
        
        // 3. 执行风控检查
        RiskCheckResult result = riskEngine.check(context);
        
        if (!result.isPass()) {
            // 记录风控事件
            riskEngine.recordRiskEvent(context, result);
            
            // 阻断请求
            ServerHttpResponse response = exchange.getResponse();
            response.setStatusCode(HttpStatus.FORBIDDEN);
            response.getHeaders().add("Content-Type", "application/json");
            
            RiskResponse riskResponse = new RiskResponse(
                result.getCode(), 
                result.getMessage());
            
            DataBuffer buffer = response.bufferFactory()
                .wrap(JSON.toJSONBytes(riskResponse));
            
            return response.writeWith(Mono.just(buffer));
        }
        
        return chain.filter(exchange);
    }
}

2. 风控规则引擎(动态规则加载)

// DynamicRuleEngine.java
@Service
@RefreshScope
public class DynamicRuleEngine {
    
    @Value("${risk.rules.config}")
    private String ruleConfigJson;
    
    private List<RiskRule> activeRules;
    
    @PostConstruct
    public void init() {
        loadRules();
    }
    
    @Scheduled(fixedRate = 60000) // 每分钟更新规则
    public void refreshRules() {
        loadRules();
    }
    
    private void loadRules() {
        this.activeRules = JSON.parseArray(ruleConfigJson, RiskRule.class)
            .stream()
            .filter(RiskRule::isEnabled)
            .collect(Collectors.toList());
    }
    
    public RiskCheckResult check(RiskContext context) {
        for (RiskRule rule : activeRules) {
            if (rule.match(context)) {
                return new RiskCheckResult(
                    false, 
                    rule.getRuleCode(), 
                    rule.getAlertMessage());
            }
        }
        return RiskCheckResult.pass();
    }
}

四、金融级监控与稳定性保障

1. 全链路监控(Micrometer + Prometheus)

# application-monitor.yml
management:
  endpoints:
    web:
      exposure:
        include: health,info,metrics,prometheus
  metrics:
    export:
      prometheus:
        enabled: true
    distribution:
      percentiles-histogram:
        http:
          server:
            requests: true
    tags:
      application: ${spring.application.name}
      region: ${spring.cloud.nacos.discovery.metadata.zone}

2. 熔断降级配置(Sentinel)

// SentinelConfig.java
@Configuration
public class SentinelConfig {
    
    @PostConstruct
    public void init() {
        // 支付接口限流规则
        FlowRule rule = new FlowRule();
        rule.setResource("executePayment");
        rule.setGrade(RuleConstant.FLOW_GRADE_QPS);
        rule.setCount(100); // 每秒100笔
        rule.setLimitApp("default");
        rule.setStrategy(RuleConstant.STRATEGY_DIRECT);
        FlowRuleManager.loadRules(Collections.singletonList(rule));
        
        // 降级规则
        DegradeRule degradeRule = new DegradeRule();
        degradeRule.setResource("riskControlCheck");
        degradeRule.setGrade(RuleConstant.DEGRADE_GRADE_EXCEPTION_RATIO);
        degradeRule.setCount(0.5); // 异常比例阈值50%
        degradeRule.setTimeWindow(10); // 熔断10秒
        DegradeRuleManager.loadRules(Collections.singletonList(degradeRule));
    }
    
    @Bean
    public SentinelResourceAspect sentinelResourceAspect() {
        return new SentinelResourceAspect();
    }
}
