## 线程池痛点
线程池是一种基于池化思想管理线程的工具,使用线程池可以减少创建销毁线程的开销,避免线程过多导致系统资源耗尽。在高并发以及大批量的任务处理场景,线程池的使用是必不可少的。
如果有在项目中实际使用线程池,相信你可能会遇到以下痛点:
- 线程池随便定义,线程资源过多,造成服务器高负载。
- 线程池参数不易评估,随着业务的并发提升,业务面临出现故障的风险。
- 线程池任务执行时间超过平均执行周期,开发人员无法感知。
- 线程池任务堆积,触发拒绝策略,影响既有业务正常运行。
- 当业务出现超时、熔断等问题时,因为没有监控,无法确定是不是线程池引起。
- 原生线程池不支持运行时变量的传递,比如 MDC 上下文遇到线程池就 GG。
- 无法执行优雅关闭,当项目关闭时,大量正在运行的线程池任务被丢弃。
- 线程池运行中,任务执行停止,怀疑发生死锁或执行耗时操作,但是无从下手。
## 什么是 Hippo-4J
Hippo-4J 通过对 JDK 线程池增强,以及扩展三方框架底层线程池等功能,为业务系统提高线上运行保障能力。
提供以下功能支持:
- 全局管控 - 管理应用线程池实例。
- 动态变更 - 应用运行时动态变更线程池参数,包括不限于:核心、最大线程数、阻塞队列容量、拒绝策略等。
- 通知报警 - 内置四种报警通知策略,线程池活跃度、容量水位、拒绝策略以及任务执行时间超长。
- 运行监控 - 实时查看线程池运行时数据,最近半小时线程池运行数据图表展示。
- 功能扩展 - 支持线程池任务传递上下文;项目关闭时,支持等待线程池在指定时间内完成任务。
- 多种模式 - 内置两种使用模式:[依赖配置中心](https://hippo4j.cn/docs/user_docs/getting_started/config/hippo4j-config-start) 和 [无中间件依赖](https://hippo4j.cn/docs/user_docs/getting_started/server/hippo4j-server-start)。
- 容器管理 - Tomcat、Jetty、Undertow 容器线程池运行时查看和线程数变更。
- 中间件适配 - Dubbo、Hystrix、Polaris、RabbitMQ、RocketMQ 等消费线程池运行时数据查看和线程数变更。
