java - 对 HttpsURLConnection 的 PATCH 请求

Question

我正在尝试用 Java 做一个 PATCH，我使用 Jersey Client 尝试了这个解决方案 PATCH 请求

但是，我得到了这个例外：

Exception in thread "AWT-EventQueue-0" java.lang.reflect.InaccessibleObjectException: Unable to make field private static final java.lang.String[] java.net.HttpURLConnection.methods accessible: module java.base does not "opens java.net" to unnamed module @6b29883d

这是我添加的代码：

    public static void modifyPATCH(final HttpURLConnection httpURLConnection, final String method) {
    try {
         Field methodsField = HttpURLConnection.class.getDeclaredField("methods");
         methodsField.setAccessible(true);
         // get the methods field modifiers
         Field modifiersField = Field.class.getDeclaredField("modifiers");
         // bypass the "private" modifier 
         modifiersField.setAccessible(true);

         // remove the "final" modifier
         modifiersField.setInt(methodsField, methodsField.getModifiers() & ~Modifier.FINAL);

         // valid HTTP methods 
         String[] methods = {
                    "GET", "POST", "HEAD", "OPTIONS", "PUT", "DELETE", "TRACE", "PATCH"
         };
         // set the new methods - including patch
         methodsField.set(null, methods);

     } catch (SecurityException | IllegalArgumentException | IllegalAccessException | NoSuchFieldException e) {
      e.printStackTrace();
     }
}

我从这个方法中调用它：

public static void connectPATCHtoken(URL url, String token) {
    
    try {
        
        connection = (HttpsURLConnection) url.openConnection(); 
        modifyPATCH(connection, "PATCH");
        connection.setRequestMethod("PATCH");   
        connection.setRequestProperty("Content-Type", "application/json; utf-8");
        connection.setRequestProperty("Accept", "application/json");
        connection.setDoOutput(true);
        String oauth = "OAuth " + token;
        connection.setRequestProperty("Authorization", oauth);
        connection.setConnectTimeout(5000);
        connection.setReadTimeout(5000);
        setConnection(connection);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
}

我究竟做错了什么？

我将 JDK 更新到 17 版，但没有帮助。
