StockTV提供了覆盖股票、外汇、期货和加密货币的全球化金融数据接口。本文将通过Spring Boot实现对这些API的快速对接并提供完整的代码示例。
一、前期准备
1. 获取API Key
访问StockTV官网联系客服获取API Key所有请求需携带key参数。
2. 创建Spring Boot项目
添加依赖
dependenciesdependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-web/artifactId/dependencydependencygroupIdorg.springframework.boot/groupIdartifactIdspring-boot-starter-websocket/artifactId/dependencydependencygroupIdcom.fasterxml.jackson.core/groupIdartifactIdjackson-databind/artifactId/dependency
/dependencies二、基础配置
1. 配置RestTemplate
Configuration
public class AppConfig {Beanpublic RestTemplate restTemplate() {return new RestTemplate();}Value(${stocktv.api.key})private String apiKey;Beanpublic HttpHeaders commonHeaders() {HttpHeaders headers new HttpHeaders();headers.add(User-Agent, SpringBootClient/1.0);return headers;}
}2. 配置API地址
application.yml:
stocktv:api:key: YOUR_API_KEYbase-url: https://api.stocktv.top三、API调用示例
1. 股票市场列表接口
Data
public class StockResponse {private Integer code;private String message;private StockData data;Datapublic static class StockData {private ListStockRecord records;private Integer total;}Datapublic static class StockRecord {private Long id;private String symbol;private String name;private Double last;private Double chgPct;}
}Service
public class StockService {Autowiredprivate RestTemplate restTemplate;Value(${stocktv.api.base-url})private String baseUrl;Value(${stocktv.api.key})private String apiKey;public StockResponse getStockList(Integer countryId, Integer page, Integer size) {String url String.format(%s/stock/stocks?countryId%dpage%dpageSize%dkey%s,baseUrl, countryId, page, size, apiKey);return restTemplate.getForObject(url, StockResponse.class);}
}2. 外汇实时汇率
Data
public class ForexResponse {private ListForexRate data;Datapublic static class ForexRate {private String symbol;private String name;private String lastPrice;private String chgPct;}
}Service
public class ForexService {public ForexResponse getForexRates(String countryType) {String url String.format(%s/market/currency?key%scountryType%s,baseUrl, apiKey, countryType);return restTemplate.getForObject(url, ForexResponse.class);}
}四、WebSocket实时数据
1. 配置WebSocket客户端
Configuration
EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer {Value(${stocktv.ws.url})private String wsUrl;Overridepublic void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {registry.addHandler(stockWebSocketHandler(), /ws/stocks).setAllowedOrigins(*);}Beanpublic WebSocketHandler stockWebSocketHandler() {return new StockWebSocketHandler();}public class StockWebSocketHandler extends TextWebSocketHandler {Overridepublic void afterConnectionEstablished(WebSocketSession session) {String wsFullUrl wsUrl ?key apiKey;session.sendMessage(new TextMessage(connect| wsFullUrl));}Overrideprotected void handleTextMessage(WebSocketSession session, TextMessage message) {// 处理实时数据String payload message.getPayload();// 解析JSON数据...}}
}五、最佳实践建议
缓存策略 对低频变化数据如市场列表使用Spring Cache
Cacheable(value stockList, key #countryId - #page)
public StockResponse getStockList(Integer countryId, Integer page, Integer size) {// ...
}异常处理 全局异常处理器
RestControllerAdvice
public class GlobalExceptionHandler {ExceptionHandler(RestClientException.class)public ResponseEntityString handleApiError(RestClientException ex) {return ResponseEntity.status(503).body(金融数据服务暂不可用: ex.getMessage());}
}安全配置 敏感信息加密存储
Configuration
public class SecurityConfig {Beanpublic EncryptablePropertyResolver encryptablePropertyResolver() {return new AES256TextEncryptor(your-secret-key);}

使用WebClient实现响应式编程集成Spring Batch处理历史数据结合Spring Scheduling实现定时数据同步使用Micrometer实现API调用监控
通过以上步骤开发者可以快速构建一个功能完备的全球金融数据服务平台。建议在正式环境中增加限流控制、请求重试等机制以保证系统稳定性。
