我正在尝试将一个对象转换为JSON，该对象具有InetSocketAddress示例作为属性。InetSocketAddress中的保持器属性被标记为 transient ，因此在序列化为JSON时被Gson忽略。
我不能删除transient关键字，因为InetSocketAddress类内置在java.net中。
我还尝试将excludeFieldsWithModifiers()用于transient和static修饰符：

final Gson gson = new GsonBuilder().excludeFieldsWithModifiers(Modifier.TRANSIENT).create();
String json = gson.toJson(registration, Registration.class);

这会产生以下错误：

java.lang.reflect.InaccessibleObjectException: Unable to make field private static final long java.net.InetSocketAddress.serialVersionUID accessible: module java.base does not "opens java.net" to unnamed module @3e849b9e
