Android Socket + ObjectOutputStream not working correctly

Hey guys. I am developing a client/server program where the client is an android device. The server has a listener class that reads an object from the input stream. I created a client software for another COMPUTER that sends a small object over a local network. Computer to Computer works perfectly fine , i read the object and printed the contents. However, the SAME code ported over to androi

Android Socket + ObjectOutputStream无法正常工作

大家好。 我正在开发一个客户端/服务器程序,客户端是Android设备。 服务器有一个从输入流中读取对象的监听器类。 我为其他计算机创建了一个客户端软件,通过本地网络发送一个小对象。 计算机到计算机的工作非常好 ,我读了对象并打印了内容。 然而,SAME代码移植到android(我重写了它以防万一)不起作用。 我构造了一个可序列化的对象(ANY对象),并通过ObjectOutputStream发送它。 我在计算机上运行的服务器确实连接

weird behavior around "same erasure" compilation error

I recently stumbled upon a piece of code that would not compile in my Eclipse due to the "same erasure" issue (looked very similar to this one). The guys who wrote the code assured me that it compiles in their local environment and their continuous integration and so I played along to emulate it. Take a look at this snippet: package com.mycompany.playground; import java.util.ArrayL

奇怪的行为围绕“相同的擦除”编译错误

我最近偶然发现了一段代码,由于“相同的擦除”问题,这段代码在我的Eclipse中无法编译(看起来与本文非常相似)。 编写代码的人向我保证,它在当地环境中编译并持续集成,所以我一直在模仿它。 看看这个片段: package com.mycompany.playground; import java.util.ArrayList; import java.util.Collection; public class GenericsTest { public static void main (String[] args) { System.out.println(Generi

JAXB workaround for Chameleon XSD imports?

this is my first question, so please be gentle ;) I'm stuck with a weird problem. Essentially i get three XSD definitions like the following: PartA.xsd targetNameSpace="PartA" include="PartB.xsd" PartB.xsd <!-- no namespace definition!!! --> PartC.xsd targetNameSpace="PartC" inlude="PartB.xsd" import="PartA.xsd" The error pops up, when binding PartC via JAXB to Java classes: A

适用于Chameleon XSD导入的JAXB解决方法?

这是我的第一个问题,所以请温和;) 我陷入了一个奇怪的问题。 基本上我得到了三个XSD定义,如下所示: PartA.xsd targetNameSpace="PartA" include="PartB.xsd" PartB.xsd <!-- no namespace definition!!! --> PartC.xsd targetNameSpace="PartC" inlude="PartB.xsd" import="PartA.xsd" 当通过JAXB将PartC绑定到Java类时,弹出错误消息: 具有相同名称“b.exampleType”的类/接口已被使用。 使用类定制来解决此

How to have 2 Threads Talk To Each Other?

I'm currently making a IRC bot in Java (I know, there are frameworks out there) and I'm trying to have it connect to multiple servers. The problem I'm having with this is not the connecting part, I'm just running my Connect class in x amount of threads. Each thread will connect the bot to the server/port specified. Now my problem is that when certain text is outputted by a user

如何让2个线程互相交谈?

我目前正在Java中制作一个IRC僵尸工具(我知道,那里有框架),我试图让它连接到多个服务器。 我遇到的问题不是连接部分,我只是在x个线程中运行Connect类。 每个线程都会将bot连接到指定的服务器/端口。 现在我的问题是,当用户输出某些文本时,机器人应该通知“你输入了这个命令”(例如)。 现在我想让机器人向所有服务器发送消息,告诉你“你输入了这个命令”。 这仅仅是一个例子(这就是为什么它没有多大意义)。 Connect

How to deserialize JSON to model object with Spring's RestController

如何使用Spring的RestController将JSON反序列化为模型对象

我正在使用Betfair的API开发REST Web应用程序,所以我需要序列化/反序列化JSON以发送HttpRequest并读取HttpResponse。 我正在使用Spring MVC,所以我想用@RestController,@RequestBody和@ResponseBody来使用Jackson,但我很努力去理解它们是如何工作的。 在下面的示例中,我向POST发送POST请求以获取用户的名和姓。 我认为HTTP响应应该反序列化到我的模型对象AccountDetailsResponse中,因为我使用了@RequestBody注释,但

spring mvc控制器接受具有可变数目的键/值的JSON对象

我知道我需要接受的JSON对象将始终是单个键和值。 我试图用@RequestBody Map和@RequestBody Map编写我的Spring MVC控制器,但是我总是收到400个错误请求。 当我将@RequestBody更改为字符串时,我看到我的数据通过,并且没有返回错误的请求响应。是否可以编写一些内容来接受任意的JSON对象,该JSON对象将始终符合作为单个密钥的合约值? @RequestMapping(value = "/advancedSearch", method = RequestMethod.POST,consumes ="ap
