我有一个Quarkus应用程序版本1.2.0最后。我有这样的解码器:
public class UuidDecoder implements Decoder.TextStream<UUID>, Decoder, Decoder.Binary<UUID>, Decoder.Text<UUID> {
public UuidDecoder() {
System.out.println("OK!");
}
@Override
public void init(EndpointConfig config
我的问题是,有时我会遇到这样的例外:
[nioEventLoopGroup-2-6] WARN io.netty.channel.DefaultChannelPipeline - An exceptionCaught() event was fired, and it reached at the tail of the pipeline. It usually means the last handler in the pipeline did not handle the exception.

Java如何确定用于System.out的编码
鉴于以下课程:
import java.io.File;
import java.io.PrintWriter;
public class Foo
{
public static void main(String[] args) throws Exception
{
String s = "xxäñxx";
System.out.println(s);
PrintWriter out = new PrintWriter(new File("test.txt&
我已经编写了自己的序列化程序来将java对象发布到主题。我将serializer.class属性设置为自定义序列化程序。在运行生产者时,我会得到以下异常。有人能帮我吗?

当我试图编译我的GWT应用程序时,我得到了很多错误。其中一些是
[ERROR] com.google.gwt.xml.client.impl.AttrImpl is not default instantiable (it must have a zero-argument constructor or no constructors at all) and has no custom serializer.

我正在尝试从Mongo DB检索文档。当不包括性别属性时,文件得到了很好的接收。但是当它被包含进来时,就会发生错误。 下面是我从Mongo检索person文档的函数 private List<Person> getPersons()

我下载并在我的应用程序中保存一个照片列表:
List<BitmapDrawable> photos = new ArrayList<BitmapDrawable>();
photos.add(Utils.bitmapToBitmapDrawable(downloadBitmap(s));
public static Bitmap downloadBitmap(String url) {
// GET input stream from server
return BitmapFactory.decodeStream(inputStream);
}

我使用java.util.Base64 (在Java8中介绍)和它的rfc2045译码器可用的Base64.getMimeDecoder()。我预计Base64编码字符串的解码时间超过76个字符会导致异常,但它似乎有效。
String value = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
// encode with rfc4648 to have a String longer than 76 chars
String encoded = new String(java.util
如果指定的映像文件包含的映像太大,则根据加载它所需的内存,将引发OutOfMemoryError。出于同样的原因,如果缩放操作的缩放因子会创建太大的图像,则会引发以下OutOfMemoryError:
