okhttp3 线程池管理
okhttp3httpclientdynamictp大约 1 分钟
使用步骤
- 引入下述依赖
<dependency>
<groupId>org.dromara.dynamictp</groupId>
<artifactId>dynamic-tp-spring-boot-starter-adapter-okhttp3</artifactId>
<version>1.1.4</version>
</dependency>
- 配置文件中配置 okhttp3 线程池
spring:
dynamic:
tp:
enabled: true
enabledCollect: true # 是否开启监控指标采集,默认false
collectorTypes: micrometer # 监控数据采集器类型(logging | micrometer | internal_logging),默认micrometer
monitorInterval: 5 # 监控时间间隔(报警判断、指标采集),默认5s
okhttp3Tp: # okhttp3 线程池配置
- threadPoolName: okHttpClientTp
corePoolSize: 100
maximumPoolSize: 200
keepAliveTime: 60
runTimeout: 200
queueTimeout: 100
- 启动日志
服务启动看到有如下日志输出说明接入成功,如果开启了通知,同时会推送参数修改通知
DynamicTp adapter, okhttp3 executors init end, executors: {okHttpClientTp=ExecutorWrapper(threadPoolName=okHttpClientTp, executor=java.util.concurrent.ThreadPoolExecutor@f336fd[Running, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 0], threadPoolAliasName=null, notifyItems=[NotifyItem(platforms=null, enabled=true, type=liveness, threshold=70, interval=120, clusterLimit=1), NotifyItem(platforms=null, enabled=true, type=change, threshold=0, interval=1, clusterLimit=1), NotifyItem(platforms=null, enabled=true, type=capacity, threshold=70, interval=120, clusterLimit=1)], notifyEnabled=true)}
DynamicTp okhttp3Tp adapter, [okHttpClientTp] refreshed end, changed keys: [corePoolSize, maxPoolSize], corePoolSize: [0 => 100], maxPoolSize: [2147483647 => 200], keepAliveTime: [60 => 60]
提示
- 服务启动会自动从 Spring 容器中获取所有被 Spring 容器管理的 OkHttpClient 实例
- 线程池名称规则:beanName + Tp(可以在启动日志找输出的线程池名称)
- okhttp3 线程池只在异步请求时生效,同步请求不会使用 okhttp3 线程池
- okhttp3 线程池享有动态调参、监控、通知告警完整的功能
- okhttp3 线程池通知告警项有(调参通知、活性告警、队列容量告警),可通过 notifyItems 自定义配置项值,默认全部开启
