编写一个java版本使用api调用kettle集群

以下是一个Java版本使用API调用Kettle集群的示例代码：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class KettleClusterAPI {

    public static void main(String[] args) throws IOException {
        String jobName = "myJob";
        String jobPath = "/myJobPath";
        String clusterIP = "192.168.1.100";
        String clusterPort = "8080";
        String endpoint = "http://" + clusterIP + ":" + clusterPort + "/kettle/api";

        // Create the URL for the job request
        String jobRequestURL = endpoint + "/job/" + jobName + "?path=" + jobPath;

        // Send the job request
        URL url = new URL(jobRequestURL);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("GET");
        connection.setRequestProperty("Accept", "application/json");

        // Read the response from the job request
        BufferedReader br = new BufferedReader(new InputStreamReader((connection.getInputStream())));
        String output;
        System.out.println("Output from Server .... \n");
        while ((output = br.readLine()) != null) {
            System.out.println(output);
        }

        // Clean up resources
        connection.disconnect();
        br.close();
    }
}

这个示例代码演示了如何使用Java语言发送一个GET请求到Kettle集群中的一个作业，并获取响应结果。你需要替换示例代码中的一些变量，如jobName、jobPath、clusterIP和clusterPort，以适应你的环境。同时，你需要确保你的Java项目中包含了Kettle的相关依赖库。
