Why reading byte array to an Object throws java.io.StreamCorruptedException?

I have a requirement to read a stream of bytes from a remote system. The remote system has its own client API to read the bytes. But at my end, I have to convert the byte array to a POJO. While doing so, I am getting error java.io.StreamCorruptedException: invalid stream header: . To test the functionality, I wrote following program to convert a String to a byte array and then convert the by

为什么读取字节数组到一个对象会抛出java.io.StreamCorruptedException?

我有要求从远程系统读取字节流。 远程系统有自己的客户端API来读取字节。 但在我的最后,我必须将字节数组转换为POJO。 虽然这样做,我得到错误java.io.StreamCorruptedException: invalid stream header: 。 为了测试功能,我编写了以下程序将String转换为byte array ,然后将字节数组转换为Object 。 public class ByteToObject { public static void main(String[] args) { try { final String str = "Tige

Generating working invokedynamic instruction with ASM

I'm working with Java bytecode via ASM and am trying to get a simple invokedynamic example functioning properly. I feel as though I'm fundamentally misunderstanding how invokedynamic is supposed to work. This is what I've tried so far: In Test2.java I have a static method I wish to invoke and my bootstrap method: public static int plus(int a, int b) { // method I want to dynamic

用ASM生成工作invokedynamic指令

我正在通过ASM使用Java字节码,并试图获得一个简单的invokedynamic示例正常运行。 我觉得好像我从根本上误解了invokedynamic应该如何工作。 这是我迄今为止所尝试的: 在Test2.java我有一个我希望调用的静态方法和我的引导方法: public static int plus(int a, int b) { // method I want to dynamically invoke return a + b; } public static CallSite bootstrap(MethodHandles.Lookup caller, String name,

Netty (4.0.4) version compress/decompress string messages error

I want to apply compress/decompress on Netty client/server I use the following code for pipeline in both client and sever: @Override protected void initChannel(SocketChannel ch) throws Exception { ChannelPipeline pipeline = ch.pipeline(); pipeline.addLast("framer", new DelimiterBasedFrameDecoder( 8192, Delimiters.lineDelimiter())); pipeline.addLast("decoder", new StringDecoder()); pipeline.

我想在Netty客户机/服务器上应用压缩/解压缩我在客户机和服务器上使用以下代码进行管道: @Override protected void initChannel(SocketChannel ch) throws Exception { ChannelPipeline pipeline = ch.pipeline(); pipeline.addLast("framer", new DelimiterBasedFrameDecoder( 8192, Delimiters.lineDelimiter())); pipeline.addLast("decoder", new StringDecoder()); pipeline.addLast("encoder", new StringEncoder())

ActiveMQ some consumers not picking up tasks if they arrive after producer

Im just getting starting with ActiveMQ and i seem to have a weird problem. (Source below) There are 2 scenarios Consumers connect to broker, waits for tasks on the queue. Producer arrives later, drops the list of tasks and they are rightly taken up by the different consumers and performed. This works fine and i have simulated it as well. Producer connects first, drops the list of tasks.

ActiveMQ一些消费者如果到达生产者后面,他们不会完成任务

我只是从ActiveMQ开始,我似乎有一个奇怪的问题。 (来源如下) 有两种情况 消费者连接到代理,等待队列中的任务。 制片人稍后到达,放下任务清单,并由不同的消费者正确接受并执行。 这工作正常,我也模拟它。 生产者首先连接,删除任务列表。 目前没有消费者连接。 现在当我们说3个消费者--C1,C2和C3连接到经纪人时(按照这个顺序),我发现只有C1接受并完成了生产者放弃的任务。 C2和C3保持空闲状态。 为什么会

java split source files

I am new to java and I have two classes (class calc and button) that I need to split into separate files and class calc uses class button. they both compile however when I run class A it fails. How can I do this? This is the code for class calc package start; import javax.swing.*; import java.awt.event.*; import java.awt.Container; import java.awt.Insets; import java.awt.Dimension;

java分割源文件

我是java的新手,我有两个类(类calc和按钮),我需要分割成单独的文件和类calc使用类按钮。 他们都编译,但是当我运行类A失败。 我怎样才能做到这一点? 这是类calc的代码 package start; import javax.swing.*; import java.awt.event.*; import java.awt.Container; import java.awt.Insets; import java.awt.Dimension; import button.*; public class calc { private button calc_buttons; private stat

Transaction rollback in a reactive application

I am using RxJava 1.1 to compose an observable sequence from inside a Spring application that looks like the following: @Transaction public Observable<Event> create(Event event) { return Observable.just(event) .flatMap(event -> { //save event to db (blocking JPA operation) Event event = eventRepository.save(event); return

事务回滚在被动应用程序中

我使用RxJava 1.1在Spring应用程序中编写了一个可观察的序列,如下所示: @Transaction public Observable<Event> create(Event event) { return Observable.just(event) .flatMap(event -> { //save event to db (blocking JPA operation) Event event = eventRepository.save(event); return Observable.just(event); })

Hibernate Composite key Criteria Join

I'm trying to perform multiple joins over a composite key. I'm using aliases to force the join creation however it seems like the join is not generated by Hibernate. I don't know why this is the case. I can get it to work with a native SQL query, but not while using criteria. I suspect it might have to do with the way how the composite key definitions are mapped (cf the associati

Hibernate复合关键标准加入

我试图通过复合键执行多个连接。 我使用别名来强制连接创建,但看起来连接不是由Hibernate生成的。 我不知道为什么会这样。 我可以让它使用原生SQL查询,但不能在使用条件时使用。 我怀疑它可能与如何映射组合键定义的方式有关(请参阅BusinessServiceUser上的associationOverrides) 以下是我的领域模型类和查询信息。 任何想法都欢迎:) 商业服务 @Entity @Table(name = "business_services") public class BusinessS
