我已经创建了一个.json文件，并希望使用rest assured方法从该json文件中获取数据。我如何才能做到这一点？

<dependency>
    <groupId>io.rest-assured</groupId>
    <artifactId>rest-assured</artifactId>
    <version>4.4.0</version>
    <scope>test</scope>
</dependency>

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;

public class JsonReader {
    public static String readJsonFile(String filePath) {
        StringBuilder content = new StringBuilder();
        try (BufferedReader reader = new BufferedReader(new FileReader(filePath))) {
            String line;
            while ((line = reader.readLine()) != null) {
                content.append(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return content.toString();
    }
}

import io.restassured.path.json.JsonPath;

public class JsonParser {
    public static void main(String[] args) {
        String jsonFilePath = "path/to/your/json/file.json";
        String jsonContent = JsonReader.readJsonFile(jsonFilePath);
        
        JsonPath jsonPath = new JsonPath(jsonContent);
        
        // 从json文件中获取数据
        String data = jsonPath.getString("key");
        
        // 打印获取到的数据
        System.out.println("Data: " + data);
    }
}
