企业分布式微服务云SpringCloud SpringBoot mybatis (五)路由网关(zuul)

在微服务架构中,需要几个基础的服务治理组件,包括服务注册与发现、服务消费、负载均衡、断路器、智能路由、配置管理等,由这几个基础组件相互协作,共同组建了一个简单的微服务系统。一个简答的微服务系统如下图: 注意:A服务和B服务是可以相互调用的,作图的时候忘记了。并且配置服务也是注册到服务注册中心的。 在Spring Cloud微服务系统中,一种常见的负载均衡方式是,客户端的请求首先经过负载均衡(zuul、Ngnix),再到达服务网关(zuul集群),然后再到具体的服。,服务统一注册到高可用的服务注册中心集群,服务的所有的配置文件由配置服务管理(下一篇文章讲述),配置服务的配置文件放在git仓库,方便开发人员随时改配置。企业分布式微服务云SpringCloud SpringBoot mybatis 一、Zuul简介 Zuul的主要功能是路由转发和过滤器。路由功能是微服务的一部分,比如/api/user转发到到user服务,/api/shop转发到到shop服务。zuul默认和Ribbon结合实现了负载均衡的功能。 zuul有以下功能: Authentication Insights Stress Testing Canary Testing Dynamic Routing Service Migration Load Shedding Security Static Response

I have created a ribbon for Powerpoint with visual studio XML ribbon. This ribbon has a button that, simplifying, does this: opens an IE browser search an element (hiddenfield) in the code by his id get the value of this element Print the value in the actual slide It works correctly the first time I click the button of my ribbon, but it throws an Exception 0x800A01B6 the following times I click the button. This is the code executed when I click the button: Dim oType As Type = Type.GetTypeFromProgID("InternetExplorer.Application") If oType IsNot Nothing Then Dim ie As SHDocVw.InternetExplorer

Custom Ribbon onAction syntax question

安稳与你 提交于 2019-11-29 13:17:10
问题 I followed the directions here to create a custom ribbon for an Access application. But none of the buttons worked! I kept getting an error that stated Access couldn't find the function or macro, even though it was public and in a standard module. Eventually I discovered that it would work if I used the following syntax: onAction="=fncMyFunction('string argument', 1234)" fncMyFunction receives the manually typed in arguments, but not the ribbon object. In Word for another project, I created a

Develop MS Access 2016 AddIn (Ribbon / VSTO) with Visual Studio 2015

拟墨画扇 提交于 2019-11-29 12:45:46
Hope you can help me. I am looking forward to programming my first MS Access AddIn with Visual Studio 2015 (a Ribbon-Bar as VSTO), but not having started I have to stop already. Visual Studio provides templates for almost every office product, but MS Access. I heard it is possible to "change" for example the Excel VSTO-Template so it can be used to develop an MS Access Ribbon. Does anyone know a good instruction how to handle this? How are you developing VSTO for MS Access? Thanks for your help There exists a tutorial for this. I haven't tried it, don't know if it works, but it sounds

Window style with WPF Ribbon from Microsoft doesn't match Windows 8 style

问题 I'm using the release Version of Windows 8 and Visual Studio 2012 to create a WPF application with a Ribbon control. I choose the ribbon control that comes with WPF in .Net Framework 4.5. My code to create the ribbon: <RibbonWindow xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfExperiments" x:Class="WpfExperiments.MainWindow" Title="MainWindow" Height="350" Width="525" Icon="Test.ico">

Customizing the PowerPoint Ribbon at Run-Time

梦想的初衷 提交于 2019-11-29 10:59:11
I am developing a PowerPoint add-in and would like to temporarily disable some of the Ribbon controls while the add-in application is running . I have developed a solution that works as expected when the Add-In is enabled , but this is not really adequate, because it disables some commonly used controls, like SlideMaster, SlideSorter, etc. I am using PowerPoint 2010. Here is a sample XML which is well-formed: <customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui"> <ribbon startFromScratch="false"> <tabs> <tab idMso="TabView"> <group idMso="GroupMasterViews" getVisible=

Ribbon 解读

Spring Cloud Ribbon 是一个基于TCP和HTTP的客户端负载均衡工具,基于Netflix Ribbon实现。虽然是一个工具类框架,它不想服务注册中心,网关等单独部署,不过它几乎存在于每一个Spring Cloud 构建的微服务体系和基础设施中。在微服务间的调用,API网观的请求转发等实际上都是通过Ribbon来实现的。包括我们常用到的Feign,也是依赖于Ribbon来实现的工具。 客户端负载均衡 负载均衡在系统架构中非常重要,并且是不得不去实施的内容。负载均衡对系统高可用,网络压力的处理,系统扩容的重要手段。我们通常所说的负载均衡是指服务端复杂均衡。如常规的硬件负载均衡F5,以及软件负载均衡Nginx等。这些都会在软件模块维护一个下挂可用的服务端清单,通过心跳检测来剔除故障的节点以保证清单中都是可用的服务端节点。当客户端发送请求到达负载均衡设备的时候,改设备按照某种算法(线性轮询,按权重轮询,按流量负载,随机等)从维护的可用服务清单中取出一台服务端地址,然后进行转发。 客户端负载均衡和服务端负载最大的不同点在于服务列表清单存储的位置。在客户端负载均衡中,所有客户端节点都要维护自己要访问的服务端清单。这些数据来源于注册中心,比如Eureka服务端。在客户端负载均衡中也需要心跳去维护服务端清单的健康性,默认会创建针对各个服务治理框架的Ribbon自动化整合配置

restTemplate 工具类

比自己封装的http工具靠谱,毕竟feign和ribbon也用这个,没有那么多需要考虑的地方,apollo也基于restTemplate封装了一个工具类。默认用的是HttpURLConnection。和okhttp比起来也差不了多少,本人在本地测了一下 import org.springframework.http.*; import org.springframework.util.CollectionUtils; import org.springframework.util.MultiValueMap; import org.springframework.web.client.RestTemplate; import java.util.Map; /** * @author liyhu * @date 2019年09月06日 */ public class RestTemplateUtil { /** * 实际执行请求的template */ private static RestTemplate restTemplate=new RestTemplate(); /** * json请求 * @param url * @param entity * @param cls * @param <T> * @return */ public static <T>T post
