如何从* java/jboss查看我的原始http post *？

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

public class Main {
    public static void main(String[] args) throws Exception {
        // 创建URL对象
        URL url = new URL("http://example.com/api/endpoint");

        // 打开连接
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();

        // 设置请求方法为POST
        connection.setRequestMethod("POST");

        // 设置请求头
        connection.setRequestProperty("Content-Type", "application/json");

        // 启用输出流，用于发送POST数据
        connection.setDoOutput(true);

        // 构造POST数据
        String postData = "{\"key\": \"value\"}";

        // 获取输出流并写入POST数据
        OutputStream outputStream = connection.getOutputStream();
        outputStream.write(postData.getBytes());
        outputStream.flush();
        outputStream.close();

        // 获取响应码
        int responseCode = connection.getResponseCode();

        // 读取响应数据
        BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        String line;
        StringBuilder response = new StringBuilder();
        while ((line = reader.readLine()) != null) {
            response.append(line);
        }
        reader.close();

        // 输出原始HTTP POST请求和响应数据
        System.out.println("Request:");
        System.out.println(connection.getRequestMethod() + " " + url);
        System.out.println(connection.getRequestProperty("Content-Type"));
        System.out.println(postData);
        System.out.println("Response:");
        System.out.println(responseCode);
        System.out.println(response.toString());
    }
}
