六大核心能力： 高性能RPC调用 智能负载均衡 服务自动注册和发现 高度可扩展能力 运行期流量调度 可视化的服务治理与运维 基础功能 RPC调用 多协议（序列化、传输、RPC） 服务注册发现 配置、元数据管理 框架分层设计，可任意扩展和组装 分析： 基本模块：Registry[注册中心]、Monitor[监控中心]、Consumer[消费者]、Provider[服务提供者] 初始化操作： Provider将服务register到registry consumer向registry服务进行subscribe 序列化操作 registry向consumer对服务的改动，上下线等进行notify consumer和Provider的服务调用，注册等情况，在Monitor进行count 同步操作 consumer对已注册的服务，向Provider直接发起invoke 在consumer中的Protocol、Cluster、Proxy 以及在Provider中的Protocol、Service、Container 均可自由扩展和组装 扩展功能 集群、高可用、管控 集群，负载均衡 治理，路由 控制台、管理与监控 灵活扩展+简单易用，是Dubbo成功的秘诀 整体架构 Config：配置层——对外配置接口，以ServiceConfig、ReferenceConfig为中心、可以直接初始化、也可以通过spring解析配置生成类 Proxy：服务代理层——服务接口透明代理，生成服务客户端的Stub和服务器端Skeleton，以serviceProxy为中心，扩展接口为proxyFactory Registry：注册中心层——封装服务地址的注册与发现，以服务Url为中心，扩展接口为RegistryFactory、Registry、RegistryService Cluster：路由层——封装多个提供者的路由及负载均衡，并桥接注册中心，以Invoker为中心，扩展接口未Cluster、Directory、Router、LoadBalance Monitor：监控层——RPC调用次数和调用时间监控、以statistics为中心，扩展接口为MonitorFactory、Monitor、MonitorService Protocol：远程调用层——封装RPC调用，以Invocation，Result为中心，扩展接口未Protocol、Invoker、Exporter exchange：信息交换层：封装请求响应模式，同步转异步，以Request、Response为中心，扩展接口为Exchanger、ExchangeClient、ExchangeServer transport：网络传输层：抽象mina和netty为统一接口，以Message为中心，扩展接口未Channel、Transporter、Client、Server、Codec

将整个堆内存进行分块，每块堆内存所分配的区域都会有改变的情况，不会将分代模型按比例进行堆内存的分配。优化了堆内存的使用效率。GC时间相比其他GC更短，但是GC更频繁。","categories":[],"tags":[]},{"title":"JVM基础","slug":"JVM基础","date":"29/06/2021","updated":"20/08/2021","comments":true,"path":"2021/06/29/JVM基础/","link":"","permalink":"http://zone.dizent.cn/2021/06/29/JVM%E5%9F%BA%E7%A1%80/","excerpt":"","text":"JDK

进入项目代码仓库，复制git地址。https://e.coding.net/dizent/fanli.git 进入本地项目目录，使用命令行将代码推送至仓库。 cd 项目目录 git init git remote add origin https://e.coding.net/dizent/fanli.git #替换为你的仓库地址 git add . git commit -m &quot;项目初始化&quot; git push origin master 查看仓库中是否已有代码，即操作成功 构建配置新的构建计划 选择项目左侧菜单栏构建与部署 –&gt;构建 在内容区域选择新建构建配置 输入计划名称，代码源选择coding、仓库选需要构建的仓库 配置来源使用静态配置的JenkinsFile–&gt;并行过程模板 勾选前往流程配置，点击保存修改流程配置 选择文本编辑器 配置解读 配置采用pipeline 默认环境下需要添加agent any ，表示“在 CODING 提供的云主机上执行 Pipeline 或 stage” 构建步骤将在stages下分布进行，每个子stage都代表一个阶段 阶段配置 检出： stage(&#39;检出&#39;) { steps { checkout([$class: &#39;GitSCM&#39;, branches: [[name: env.GIT_BUILD_REF]], userRemoteConfigs: [[url: env.GIT_REPO_URL, credentialsId: env.CREDENTIALS_ID]]]) } } 在仓库检出，此阶段配置无需改动，都默认为上一步构建计划的参数 构建 stage(&#39;构建&#39;) { steps { echo &#39;构建中...&#39; sh &#39;java -version&#39; sh &#39;mvn package&#39; echo &#39;构建完成.&#39; archiveArtifacts(artifacts: &#39;**/target/*.jar&#39;, fingerprint: true) } } echo为输出信息，不作其他解释 检查Java版本 Maven打包，打包在项目路径的../target/*.jar 收集打包后的文件 测试 stage(&#39;测试&#39;) { steps { echo &#39;单元测试中...&#39; sh &#39;mvn test&#39; echo &#39;单元测试完成.&#39; } } 执行Maven测试，测试test包下的代码 部署 stage(&#39;部署&#39;) { steps

配置服务器的ssh密钥，并导入coding凭据。相关操作见coding使用凭证进行认证 上传文件到服务器 运行服务器端的脚本deploy.sh deploy.sh脚本内容如下 #!/bin/sh ## java 环境 export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.232.b09-0.el7_7.x86_64 ## jre环境

可以将上方用到的变量使用变量配置，即可多项目使用 缓存目录：项目目录 Maven打开 通知提醒 选择在构建时开启邮件提醒，并选择成员 开始构建所有配置完成之后，即可点击开始构建 ，可以查看构建进度。 参考文章： coding部署到-Linux-Web-服务器 coding在持续集成中使用凭据 Linux 运行jar包命令
