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");}
}
六、完整项目结构
src/
├── main/
│ ├── java/
│ │ └── com/example/finance/
│ │ ├── config/ # 配置类
│ │ ├── model/ # 数据模型
│ │ ├── service/ # 业务服务
│ │ └── controller/ # API端点
│ └── resources/
│ ├── application.yml
└── test/ # 测试用例
七、扩展建议
- 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。
