spring远程调用

Spring 远程调用 远程调用是客户端应用和服务端之间的会话。在客户端上所需要的一些功能并不包括在该应用的职能范围内。所以应用向能提供这些功能的其他系统寻求帮助。远程的应用通过远程服务把这些功能公开出来。 一、Spring远程调用概览 Spring为各种远程访问技术的集成提供了工具类。Spring远程支持是由普通(Spring)POJO实现的,这使得开发具有远程访问功能的服务变得相当容易。 Spring远程调用支持6种不同的RPC模式:远程方法调用(RMI)、Caucho的Hessian和Burlap、Spring自己的HTTP invoker、EJB和使用JAX-RPC 的Web Services。 RPC模式 在何种情况下有用 远程方法调用(RMI) 不考虑网络限制(如防火墙)时,访问/公开基于Java的服务 Hessian或 Burlap 考虑网络限制时,通过HTTP访问/公开基于Java的服务 HTTP invoker 考虑网络限制时,访问/公开基于Spring的服务 EJB 访问用EJB实现的遗留的J2EE系统 JAX-RPC 访问Web Services 其中(来自Spring2.0参考手册): l 远程方法调用(RMI)。通过使用 RmiProxyFactoryBean和 RmiServiceExporter,Spring同时支持传统的RMI(使用java.rmi

C/C++ RPC Tutorial for Linux [closed]

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 6 years ago . Can someone point me to a decent RPC tutorial for (or books) linux, like in this post. I tried looking around myself, I've only found tutorials that are really old. Thanks 回答1: Since the idea of RPC goes back to 1976 and the first business use was by Xerox in 1981, I'm not exactly sure what qualifies as a really

IDL for JSON REST/RPC interface

妖精的绣舞 提交于 2019-12-03 16:27:12
问题 We are designing a fairly complex REST API, in which most of the I/O are JSON encoded objects with a specific structure. One challenge we have found is to document the API in such a way that makes it easier for clients to post correct input and process output. Because the data of both the input and output requires fairly complex JSON objects, client developers often introduce bugs related to the structure of the I/O objects. With all of the JSON web API's these days, I would have hoped for a

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . Is there something like this for Windows? If not, what is the easiest/quickest way to test an XML RPC? 回答1: I'm using xmlrpc-test-tool, a browser tool: http://code.google.com/p/xmlrpc-test/ 回答2: Browser tools: Firefox: http://restclient.net/ Chrome: https://chrome.google.com

Python中实现远程调用(RPC、RMI)简单例子

╄→尐↘猪︶ㄣ 提交于 2019-12-03 16:21:18
说白了,远程调用就是将对象名、函数名、参数等传递给远程服务器,服务器将处理结果返回给客户端 远程调用使得调用远程服务器的对象、方法的方式就和调用本地对象、方法的方式差不多,因为我们通过网络编程把这些都隐藏起来了。远程调用是分布式系统的基础。 远程调用一般分为两种,远程过程调用(RPC)和远程方法调用(RMI)。 RPC RPC属于函数级别的远程调用,其多是通过HTTP传输数据,数据形式有XML、JSON、序列化数据等。在此,用python做一个xml-rpc的示例。 先给服务器端server.py: from SimpleXMLRPCServer import SimpleXMLRPCServer def add(x, y): return x + y if __name__ == '__main__': s = SimpleXMLRPCServer(('127.0.0.1', 8080)) s.register_function(add) s.serve_forever() s是一个绑定了本地8080端口的服务器对象,register_function()方法将函数add注册到s中。serve_forever()启动服务器。 再给个客户端client.py: from xmlrpclib import ServerProxy if __name__ == '__main__':

SOAP RPC/Encoded convert to RPC/Literal

五迷三道 提交于 2019-12-03 16:19:40
Does anyone know of a tool or 'blackbox' that would convert a RPC/Encoded WSDL to RPC/Literal? I don't have the ability to change the API (it's not mine) but the tool I want to use does not support RPC/Encoded. I'd like to see if someone has created a simple black box communication converter. I want to use wave maker and i'm not a programmer so I'm looking for a tool to just take care of the translation. If you are changing the encoding of the WSDL, then the SOAP messages would change to: RPC/Encoded Message Sample <soap:envelope> <soap:body> <myMethod> <x xsi:type="xsd:int">5</x> <y xsi:type=

dotnet core各rpc组件的性能测试

喜欢而已 提交于 2019-12-03 13:16:50
dotnet core各rpc组件的性能测试 一般 rpc 通讯组件都具有高性特性,因为大部分 rpc 都是基于二进制和连接复用的特点,相对于 HTTP (2.0以下的版本)来说有着很大的性能优势,非常适合服务间通讯交互。本文针对了dotnet core平台上的一些 rpc 组件进行性能测试,主要包括 grpc , Orleans , xrpc 和 netx ;其实平台下的 rcp 组件有很多,毕竟个人精力有限并没有一一添加到测试里面去;如果大家有兴趣可以参与进来 https://github.com/IKende/dotnet-rpc-benchmark 添加或优化测试代码并提交相关PR。 测试描述 为了更好的体现实际应用的情况,功能和网络环境都会多样性测试。调用测试是基于远程对象或接口的方式操作,操作方法包括简单和相对复杂的对象;测试的物理网络环境包括10Gb和普通网络1Gb.分别测试16,32,64,128和256等不同的请求并发并获取相关的总请求量和秒并发值。 测试工具 https://github.com/IKende/CodeBenchmarkDoc 测试物理环境 Client E3-1230v2 16g Server E5-2670v2 32g Network 10Gb和1Gb System Windows server 测试接口描述 public interface

Why is exactly once semantics infeasible?

与世无争的帅哥 提交于 2019-12-03 12:25:53
问题 In RPC semantics where Erlang has hope for the best, SUN RPC with at-least once and Java RMI with at-most-once but no one has exactly once semantics. Why does it seem infeasible to have exactly once semantics? For example if the client keeps resending a uniquely tagged request until a reply is received and a server keeps track of all handled requests in order not to duplicate a request. Would that not be exactly once? 回答1: Consider what happens if the server crashes between carrying out the
