这篇文章主要介绍“Java动态线程池插件dynamic-tp怎么使用”,在日常操作中,相信很多人在Java动态线程池插件dynamic-tp怎么使用问题上存在疑惑,小编查阅了各式资料,整理出简单好用的操作方法,希望对大家解答”Java动态线程池插件dynamic-tp怎么使用”的疑惑有所帮助!接下来,请跟着小编一起来学习吧!

    前言

    dynamic-tp
    是一个轻量级的动态线程池插件,它是一个基于配置中心的动态线程池,线程池的参数可以通过配置中心配置进行动态的修改,目前支持的配置中心有
    Apollo
    ,
    Nacos
    Zookeeper
    ,同时
    dynamic-tp
    支持线程池的监控和报警,具体特性如下:

      基于

      Spring
      框架,现只支持
      SpringBoot
      项目使用,轻量级,引入 starter 即可使用

      基于配置中心实现线程池参数动态调整,实时生效;集成主流配置中心,已支持 Nacos、Apollo,Zookeeper, 同时也提供 SPI 接口可自定义扩展实现

      内置通知报警功能,提供多种报警维度(配置变更通知、活性报警、容量阈值报警、拒绝策略触发报警), 默认支持企业微信、钉钉报警,同时提供 SPI 接口可自定义扩展实现

      内置线程池指标采集功能,支持通过 MicroMeter、JsonLog 日志输出、Endpoint 三种方式,可通过 SPI 接口自定义扩展实现

      集成管理常用第三方组件的线程池,已集成 SpringBoot 内置 WebServer(tomcat、undertow、jetty)的线程池管理

      Builder 提供

      TTL
      包装功能,生成的线程池支持上下文信息传递

    快速开始

    pom依赖

    dynamic-tp-spring-boot-starter-zookeeper
    是集成
    dynamic-tp
    的starter,这里引入了
    micrometer-registry-prometheus
    spring-boot-starter-actuator
    用于对接
    Prometheus

    YML配置

    server:
      port: 8888

    spring:
      application:
        name: dynamic-tp-zookeeper-demo
      # 下面是接入zk配置中心的配置  
      dynamic:
        tp:
          config-type: properties # zookeeper只支持properties配置
          zookeeper:
            config-version: 1.0.0 # 配置版本号
            zk-connect-str: 127.0.0.1:2181 # zk配置中心,如果是集群用逗号分开
            root-node: /configserver/userproject # 项目节点
            node: dynamic-tp-zookeeper-demo # 配置文件节点
    # 对接prometheus
    management:
      metrics:
        tags:
          application: ${spring.application.name}
      endpoints:
        web:
          exposure:
            include: '*'

    配置中心dynamic-tp-zookeeper-demo配置文件配置

    注:Zookeeper配置中心只支持

    properties
    类型配置,配置示例如下:

    spring.dynamic.tp.executors
    部分是对线程池的配置,该配置是数组类型,可以定义多个线程池

    spring.dynamic.tp.executors[1].notifyItems
    部分配置是对线程池报警平台的配置,可以配置多个报警平台

    创建线程池

    创建线程池,会注册到

    dynamic-tp

    @Configuration
    public class ThreadPoolConfiguration {
        @Bean
        public DtpExecutor dtpExecutor() {
    
            return ThreadPoolCreator.createDynamicFast("dynamic-tp-test-1");
        }
        @Bean
        public ThreadPoolExecutor threadPoolExecutor() {
            return ThreadPoolBuilder.newBuilder()
                    .threadPoolName("dynamic-tp-test-2")
                    .corePoolSize(10)
                    .maximumPoolSize(15)
                    .keepAliveTime(15000)
                    .timeUnit(TimeUnit.MILLISECONDS)
                    .workQueue(QueueTypeEnum.SYNCHRONOUS_QUEUE.getName(), null, false)
                    .buildDynamic();
        }
    }

    使用

    初次使用不注意官网文档的话可能会通过

    @Autowired
    的方式使用,目前版本这么使用是不正确的,因为当读取配置文件后,配置文件生成的线程池对象就会把
    @Bean
    创建的线程池覆盖了,所以目前版本只能根据名字从
    DtpRegistry
    获取线程池对象了,笔者也和项目作者沟通过,项目作者也觉得通过
    @Autowired
    方式更好一些,后面版本也会优化。

    @Slf4j
    @RestController
    @SuppressWarnings("all")
    public class TestController {
        @GetMapping("/dtp-zookeeper-example/test")
        public String test() {
            new Thread(() -> {
                try {
                    task();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }).start();
            return "success";
        }
        public void task() throws InterruptedException {
            DtpExecutor dtpExecutor1 = DtpRegistry.getExecutor("dynamic-tp-test-1");
            DtpExecutor dtpExecutor2 = DtpRegistry.getExecutor("dynamic-tp-test-2");
            for (int i = 0; i < 100; i++) {
                Thread.sleep(100);
                dtpExecutor1.execute(() -> {
                    log.info("i am dynamic-tp-test-1 task");
                });
                dtpExecutor2.execute(() -> {
                    log.info("i am dynamic-tp-test-2 task");
                });
            }
        }
    }

    监控数据和第三方平台对接

    logging方式

    spring.dynamic.tp.collectorType=logging
    ,logging方式的监控数据,采集日志文件中,文件的位置可以通过
    spring.dynamic.tp.logPath
    配置,默认 ${user.home}/logs,日志内容如下:

    2022-03-07 13:48:31.585 INFO [dtp-monitor1:D.M.LOG] {"activeCount":0,"queueSize":0,"largestPoolSize":0,"poolSize":0,"rejectHandlerName":"CallerRunsPolicy","queueCapacity":0,"fair":false,"rejectCount":0,"waitTaskCount":0,"taskCount":0,"queueRemainingCapacity":0,"corePoolSize":40,"queueType":"SynchronousQueue","completedTaskCount":0,"dtpName":"dynamic-tp-test-2","maximumPoolSize":55}
    2022-03-07 13:48:31.585 INFO [dtp-monitor1:D.M.LOG] {"activeCount":0,"queueSize":0,"largestPoolSize":0,"poolSize":0,"queueCapacity":2147483647,"fair":false,"rejectCount":0,"waitTaskCount":0,"taskCount":0,"queueRemainingCapacity":2147483647,"corePoolSize":10,"queueType":"TaskQueue","completedTaskCount":0,"dtpName":"tomcatWebServerTp","maximumPoolSize":200}
    2022-03-07 13:48:36.590 INFO [dtp-monitor1:D.M.LOG] {"activeCount":0,"queueSize":0,"largestPoolSize":0,"poolSize":0,"rejectHandlerName":"CallerRunsPolicy","queueCapacity":1024,"fair":false,"rejectCount":0,"waitTaskCount":0,"taskCount":0,"queueRemainingCapacity":1024,"corePoolSize":50,"queueType":"VariableLinkedBlockingQueue","completedTaskCount":0,"dtpName":"dynamic-tp-test-1","maximumPoolSize":50}
    2022-03-07 13:48:36.590 INFO [dtp-monitor1:D.M.LOG] {"activeCount":0,"queueSize":0,"largestPoolSize":0,"poolSize":0,"rejectHandlerName":"CallerRunsPolicy","queueCapacity":0,"fair":false,"rejectCount":0,"waitTaskCount":0,"taskCount":0,"queueRemainingCapacity":0,"corePoolSize":40,"queueType":"SynchronousQueue","completedTaskCount":0,"dtpName":"dynamic-tp-test-2","maximumPoolSize":55}
    2022-03-07 13:48:36.590 INFO [dtp-monitor1:D.M.LOG] {"activeCount":0,"queueSize":0,"largestPoolSize":0,"poolSize":0,"queueCapacity":2147483647,"fair":false,"rejectCount":0,"waitTaskCount":0,"taskCount":0,"queueRemainingCapacity":2147483647,"corePoolSize":10,"queueType":"TaskQueue","completedTaskCount":0,"dtpName":"tomcatWebServerTp","maximumPoolSize":200}

    MicroMeter方式

    spring.dynamic.tp.collectorType=micrometer
    采集数据到第三方平台,这里使用的是
    Prometheus
    。可视化展示需要在
    Grafana
    平台配置,数据源选择
    Prometheus
    ,然后创建
    Dashboard
    ,先要在
    Dashboard
    配置动态的参数
    Variables
    ,如下图:

    配置完参数后,我们创建

    Panel
    ,可以创建多个
    Panel
    ,然后配置
    Panel
    的数据查询,报警显示等等,如下图:

    最终的Dashboard如下图:
