随着对印度市场兴趣的增长,获取实时和历史股市数据变得至关重要。本文将简明介绍如何利用Spring Boot框架对接StockTV API,以轻松访问印度股票市场的数据。
准备工作
获取API Key
首先,确保您已从StockTV获得了API Key。这是调用API时的身份验证凭证。联系StockTV团队获取您的专属Key。
创建Spring Boot项目
通过Spring Initializr创建一个Spring Boot项目,并添加以下依赖:
- Spring Web
- Lombok(可选)
导入生成的项目到IDE中。
获取K线数据
配置RestTemplate Bean
在配置类中定义RestTemplate Bean:
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;
@Configuration
public class AppConfig {
@Bean
public RestTemplate restTemplate() {
return new RestTemplate();
}
}
实现服务层
创建服务类来封装API请求逻辑:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestTemplate;
import org.json.JSONArray;
import org.json.JSONObject;
@Service
public class StockDataService {
private final String apiUrl = "https://api.stocktv.top/stock/kline?symbol=INFY&interval=1day&startTime=START_TIME&endTime=END_TIME&key=YOUR_API_KEY";
private final RestTemplate restTemplate;
@Autowired
public StockDataService(RestTemplate restTemplate) {
this.restTemplate = restTemplate;
}
public JSONArray fetchKLineData() {
String jsonResponse = restTemplate.getForObject(apiUrl, String.class);
JSONObject jsonObject = new JSONObject(jsonResponse);
return jsonObject.getJSONArray("data");
}
}
创建控制器
提供REST端点供客户端调用:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.json.JSONArray;
@RestController
public class StockDataController {
private final StockDataService stockDataService;
@Autowired
public StockDataController(StockDataService stockDataService) {
this.stockDataService = stockDataService;
}
@GetMapping("/kline")
public JSONArray getKLineData() {
return stockDataService.fetchKLineData();
}
}
WebSocket实时数据
对于WebSocket支持,添加依赖并实现监听器:
添加WebSocket依赖
在pom.xml中添加:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
实现WebSocket监听器
简单的监听器示例:
import org.springframework.messaging.simp.stomp.StompFrameHandler;
import org.springframework.messaging.simp.stomp.StompHeaders;
import org.springframework.stereotype.Component;
import java.lang.reflect.Type;
@Component
public class StockWebSocketListener implements StompFrameHandler {
@Override
public Type getPayloadType(StompHeaders headers) {
return String.class;
}
@Override
public void handleFrame(StompHeaders headers, Object payload) {
System.out.println("Received message: " + payload);
}
}
启动WebSocket连接
在应用启动时初始化连接:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;
import java.util.concurrent.ExecutionException;
@Component
public class WebSocketInitializer {
private final WebSocketStompClient stompClient;
private final StockWebSocketListener listener;
@Autowired
public WebSocketInitializer(WebSocketStompClient stompClient, StockWebSocketListener listener) {
this.stompClient = stompClient;
this.listener = listener;
}
@PostConstruct
public void initialize() throws ExecutionException, InterruptedException {
String url = "wss://api.stocktv.top/connection?key=YOUR_API_KEY";
StompSession session = stompClient.connect(url, new StompSessionHandlerAdapter() {}).get();
listener.connectAndSubscribe(session);
}
}
通过上述步骤,您可以快速搭建起与印度股票市场的数据交互平台,无论是进行数据分析还是构建实时报价系统,都能为您提供坚实的基础。希望这篇简洁指南能帮助您顺利对接所需的数据源。
