使用Spring Boot对接StockTV全球金融数据API指南

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：

<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-websocket</artifactId></dependency><dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-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 List<StockRecord> 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=%d&page=%d&pageSize=%d&key=%s",baseUrl, countryId, page, size, apiKey);return restTemplate.getForObject(url, StockResponse.class);}
}

2. 外汇实时汇率

@Data
public class ForexResponse {private List<ForexRate> 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=%s&countryType=%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 ResponseEntity<String> 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");}
}
