I've been struggling with this for days without any idea in how to solve it. Basically I have the following WSDL service definition: <?xml version='1.0' encoding='UTF-8'?><!-- Published by JAX-WS RI at http://jax-ws.dev.java.net. RI's version is Metro/2.2.0-1 (tags/2.2.0u1-7139; 2012-06-02T10:55:19+0000) JAXWS-RI/2.2.6-2 JAXWS/2.2 svn-revision#unknown. --><!-- Generated by JA

In C# you can enclose a lambda expression in an expression tree object and then possibly parse it. I was wondering if this is also possible in Java? What I'm looking for is doing something like this: BooksRepository.getAll() .where(b -> b.getIban() == "SomeIban") .and(b -> b.getAuthor() == "SomeAuthor"); //etc. And then the BooksRepository should somehow translate that query to the
在C＃中，您可以在表达式树对象中包含一个lambda表达式，然后可能解析它。 我想知道这是否也可以在Java中使用？ 我在找的是做这样的事情： BooksRepository.getAll() .where(b -> b.getIban() == "SomeIban") .and(b -> b.getAuthor() == "SomeAuthor"); //etc. 然后， BooksRepository应以某种方式将该查询转换为以下基于指定为lambdas的谓词的RESTful API请求： GET http://mylibrary.com/books?Iban=SomeIban&
Possible Duplicate: What is the Java equivalent for LINQ? There are numerous questions asking whether there is a Java equivalent for LINQ. But most of them are incorrectly specifying that there is nothing.

I'm new with RabbitMq and AMQP but I have some experience with ActiveMQ and JMS. I try to publish a message in a topic (topic like topic in JMS) and to consume this message from several listeners. For example, I publish a message saying there is a new user in the system, and there is one consumer to send an email to this user, and another consumer indexing this user in elasticsearch. So, e
我是RabbitMq和AMQP的新手，但我对ActiveMQ和JMS有一些经验。 我尝试在一个主题（像JMS中的主题这样的主题）中发布消息，并从几个监听器中消费这个消息。 例如，我发布了一条消息，指出系统中有一个新用户，并且有一位消费者向该用户发送电子邮件，另一位消费者在elasticsearch中为该用户编制索引。 因此，每消费必须阅读消息，直到它可以从主题中删除。 我试图用这种方式使用TopicExchange： @Bean public TopicExchange p
The RabbitMQ Java client has the following concepts: Connection - a connection to a RabbitMQ server instance Channel - ??? Consumer thread pool - a pool of threads that consume messages off the RabbitMQ server queues Queue - a structure that holds messages in FIFO order I'm trying to understand the relationship, and more importantly , the associations between them. I'm still n
RabbitMQ Java客户端具有以下概念： Connection - 与RabbitMQ服务器实例的连接 Channel - ??? 消费者线程池 - 消耗RabbitMQ服务器队列消息的线程池 队列 - 按FIFO顺序保存消息的结构 我试图理解这种关系， 更重要的是 ，他们之间的关系。 我还不太确定Channel是什么，除了这是您发布和使用的结构，并且它是从一个开放连接创建的。 如果有人能向我解释“频道”代表什么，它可能有助于清除一些事情。 Channel和Queue
I have the code segment below. If the RabbitMQ server drops off the connection seems to return null and a new connection is established. I am suspicious that repeated attempts to reconnect to the server is eating up memory, but I am not sure why. How should a lost connection (server unavailable) be handled? public Connection getConnection( ) { if (myConnection == null) { start();
我有下面的代码段。 如果RabbitMQ服务器断开连接似乎返回null并建立新的连接。 我怀疑重复尝试重新连接到服务器正在耗尽内存，但我不知道为什么。 如何处理丢失的连接（服务器不可用）？ public Connection getConnection( ) { if (myConnection == null) { start(); } return myConnection; } private void start() { log.debug("Building AMQP Connection"); ConnectionFactory factory = ne
I learn nio now, but I don't know how to send message without client send me message firstly after it connected with server. I try to cache SelectionKey and SocketChannel, but it does'n t work. So how can I solve this problem. Thanks. I solved the problem，there are two methods selectKeys and keys, selectKeys can get all channels that receive an action. keys can get all channels tha
我现在学习nio，但是我不知道如何在没有客户端的情况下发送消息。 我尝试缓存SelectionKey和SocketChannel，但它不起作用。 那我该如何解决这个问题。 谢谢。 我解决了这个问题，有两种方法selectKeys和keys，selectKeys可以获得接收动作的所有通道。 密钥可以获得与服务器连接的所有通道，我可以使用密钥方法直接发送消息。
I'm writing a toy Java NIO server paired with a normal Java client. The client sends a string message to the server using plain Socket. The server receives the message and dumps the content to terminal. I've noticed that the same message from client is broken up into bytebuffers differently every single time. I understand this is intended behaviour of NIO, but would like to find out
我正在写一个玩具Java NIO服务器与普通的Java客户端配对。 客户端使用普通的Socket向服务器发送字符串消息。 服务器收到消息并将内容转储给终端。 我注意到，客户端发出的相同消息每次都以不同的方式分解为不同的字节缓冲区。 我知道这是NIO的预期行为，但想大致了解NIO如何决定切断信息？ 示例：向服务器发送字符串“这是测试消息”。 以下是服务器日志摘录（每行代表1个接收的字节缓冲区）。 Run 1: Server receiving: t
friends! I'm new to Java NIO and I'm currently trying to make a non-blocking chat app. The client connects to the server without problem. The client writes a message or few messages to the server but the server starts reading the messages only when the Socket connection is closed from the client code, so a SocketChannel (or only Socket) must be created and closed in the client code for
朋友们！ 我是Java NIO的新手，目前我正在尝试制作一个无阻塞的聊天应用程序。 客户端连接到服务器没有问题。 客户端向服务器写入消息或少量消息，但服务器只有在客户端代码关闭Socket连接时才开始读取消息，因此必须为客户端代码创建并关闭每个消息的SocketChannel（或仅Socket）。 - 这在我看来不正确。 我用简单的Java I / O和NIO Selector尝试了客户端。 同样的问题 - 服务器只有在客户端关闭SocketChannel或Socket时才
I have a client/server application where two users write to each other and also can send large files to each other, i used ServerSocket and Socket classes to do this and everything was fine except of slow file transfer, this was the code: Client side: public void sendFileRequest(Path filePath) { try { DataOutputStream output = new DataOutputStream(socket.getOutputStream());
我有一个客户端/服务器应用程序，其中两个用户互相写入，也可以将大型文件发送给对方，我使用ServerSocket和Socket类来执行此操作，除慢文件传输外，一切都很好，这是代码： 客户端： public void sendFileRequest(Path filePath) { try { DataOutputStream output = new DataOutputStream(socket.getOutputStream()); output.writeUTF("FILE_REQUEST"); output.writeUTF(gui.getFilePath().to
