ElasticTimer

介绍

使用zookeeper协同的分布式动态定时器,可随时加载卸载任务,暴露dubbo服务进行管理行为,无需额外存储

软件架构

spring:生命周期管理与Quarzt整合 quarzt:定时任务实现 zookeeper:任务协调 dubbo:定时器相关服务管理 curator-framework: zookeeper 客户端,封装监听,注册加载节点

安装教程

版本说明

你需要按照当前的项目进行版本选择,以下表格会进行实时更新

JDK版本 ElasticTimer版本 Spring版本 zookeeper版本 curator版本 dubbo版本 quarzt版本 功能 更新时间
1.7 1.0.0 3.1.0.RELEASE 3.3.3 1.0.6 2.5.3 1.6.3 动态加载、卸载任务、dubbo服务(更新、添加、删除、同步)、配置持久化、无外部存储 2020-04-29 13:06:26 星期三
基于Spring 安装
  1. 下载最新或指定分支版本源码
  2. 进行maven编译(国内可配置 ali 源,资源会比较全) mvn clean install
  3. 代码中引入依赖
    <dependency>
      <groupId>com.m31skytech</groupId>
      <artifactId>ElasticTimer</artifactId>
      <version>${targetVersion}</version>
    </dependency>  

暂时不提供非依赖Spring版本

使用说明

  1. 在任一Spring配置文件中添加包扫描声明 <context:component-scan base-package="com.m31skytech.ElasticTimer" />

  2. 编写基于Spring Quarzt 的配置文件,该部分可参考Quartz 官方配置指南 http://www.quartz-scheduler.org/

  3. 将所使用的 org.springframework.scheduling.quartz.SchedulerFactoryBean 进行如下配置引入

    <bean id="quarztHandleProxy" class="com.m31skytech.ElasticTimer.timer.ElasticTimerQuarztHandleProxy">
        <property name="innerSchedule" ref="scheduleFactory"/>
    </bean>
  1. 在资源目录下新建 elastictimer.properties 文件,按照以下参数列表进行填写
属性名 可空 描述
elastictimer.config.type N 配置方式,目前支持2种,代理或直连 proxy/direct
elastictimer.config.proxy.filename Y 使用 proxy 模式时非空,表示所代理的属性值文件全名该文件应该放在 resources 目录下,例:dubbo.properties
elastictimer.config.proxy.zookeeper.path Y 使用 proxy 模式时非空,表示代理配置文件中的代表zookeeper 注册中心地址的配置属性名,例:在dubbo.properties 中存在以下配置 dubbo.registry.address=zookeeper://127.0.0.1:2181 则应该填写 elastictimer.config.proxy.zookeeper.path=dubbo.registry.address
elastictimer.config.proxy.application.code Y 使用 proxy 模式时非空,表示代理配置文件中的代表dubbo application code的配置属性名
elastictimer.config.proxy.owner.code Y 使用 proxy 模式时非空,表示代理配置文件中的代表dubbo owner code的配置属性名
elastictimer.config.proxy.dubbo.port Y 使用 proxy 模式时非空,表示代理配置文件中的代表dubbo port的配置属性名
elastictimer.zookeeper.path Y 使用 direct 模式时应填写,表示所链接的注册中心值,默认值为: zookeeper://127.0.0.1:2181
elastictimer.application.code Y 使用 direct 模式时应填写,表示dubbo服务所使用的appname,默认值为 ElasticTimerApp
elastictimer.owner.code Y 使用 direct 模式时应填写,表示dubbo服务所使用的ownercode,默认值为 M31
elastictimer.dubbo.port Y 使用 direct 模式时应填写,表示dubbo服务所使用的端口,默认值为 20880
