服务名称：SimpleStockQuoteService

1. **API定义**：
   - **GET /quote/{stockSymbol}**:
     - 请求参数：`stockSymbol`（股票代码）
     - 返回值：包含当前股价、最新消息等的JSON对象。

2. **客户端示例**（使用Java中的HTTP客户端库，例如Apache HttpClient或Java's HttpURLConnection）：

```java
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.json.JSONObject;

import java.io.IOException;

public class SimpleStockQuoteClient {
    private static final String STOCK_SYMBOL = "AAPL"; // Apple Inc. for example

public JSONObject getLatestStockPrice() throws IOException {
        HttpGet httpGet = new HttpGet("http://localhost:8080/quote/" + STOCK_SYMBOL);
        HttpResponse response = executeHttpClient(httpGet);

if (response.getStatusLine().getStatusCode() == 200) {
            String jsonResponse = EntityUtils.toString(response.getEntity()));
            JSONObject stockPriceJson = new JSONObject(jsonResponse);
            return stockPriceJson;
        } else {
            throw new IOException("Failed to fetch stock price, response status code: " + response.getStatusLine().getStatusCode());
        }
    }

private HttpResponse executeHttpClient(HttpGet httpGet) throws IOException {
        HttpClient httpClient = HttpClients.createDefault();
        try (CloseableHttpResponse response = httpClient.execute(httpGet)) {
            return response;
        } finally {
            httpClient.close();
        }
    }
}
```

这个客户端示例使用了Apache HttpClient库来发送HTTP GET请求获取股票价格。你需要先在项目中添加Apache HttpClient的依赖。
