**动态线程池监控**，主意来源于美团技术公众号 [点击查看美团线程池文章](https://tech.meituan.com/2020/04/02/java-pooling-pratice-in-meituan.html)
|
|
|
|

看了文章后深受感触，再加上最近线上线程池的不可控以及不可逆等问题，想做出一个 **兼容性、功能性、易上手等特性** 集于一身的的开源项目，目标还是要有的
|
|
|
|
|
|
|
|
|
|
|
|
<br/>
|
|
|
|
|
|
|
|
|
|
|
|
目前项目由作者独立开发，时间在下班后、周六天等。具体什么时候能发布 1.0.0 版本不好说，需要看实际的开发情况
|
|
|
|
|
|
|
|
|
|
|
|
<br/>
|
|
|
|
|
|
|
|
|
|
|
|
根据目前的想法，美团技术文章中支持的特性，DTP（Dynamic Thread Pool）项目都会兼容进去，可能部分会因为作者技术有限，无法兼容
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
比如：
|
|
|
|
|
|
|
|
|
|
|
|
- 修改阻塞队列长度
|
|
|
|
|
|
|
|
|
|
|
|
- 修改线程池核心线程数、最大线程数、线程存活时长...
|
|
|
|
|
|
|
|
|
|
|
|
- 线程池详细信息监控
|
|
|
|
|
|
|
|
|
|
|
|
- 线程池负载报警
|
|
|
|
|
|
|
|
|
|
|
|
- ...
|
|
|
|
|
|
|
|
|
|
|
|
<br/>
|
|
|
|
|
|
|
|
|
|
|
|
**项目不会强依赖某个不通用的中间件**，对于小体量的工程，越是轻便越会有人想要去了解以及使用
|
|
|
|
|
|
|
|
|
|
|
|
<br/>
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|

|
## 本地部署
|
|
|
|
|
|
|
|
|
|
|
|
目前动态线程池功能已经完成，可以直接把代码拉到本地运行。项目中数据库是作者 ECS Docker 搭建，大家直接使用即可
|
|
|
|
|
|
|
|
|
|
|
|
<br/>
|
|
|
|
|
|
|
|
|
|
|
|
1. 启动 server 模块下 ServerApplication 启动类
|
|
|
|
|
|
|
|
|
|
|
|
<br/>
|
|
|
|
|
|
|
|
|
|
|
|
2. 启动 example 模块下 ExampleApplication 启动类
|
|
|
|
|
|
|
|
|
|
|
|
<br/>
|
|
|
|
|
|
|
|
|
|
|
|
3. 可以通过调用接口修改线程池配置。修改请求如下，**请求时勿动 tenantId、itemId、tpId**
|
|
|
|
|
|
|
|
|
|
|
|
<br/>
|
|
|
|
|
|
|
|
|
|
|
|
```json
|
|
|
|
|
|
POST http://localhost:6691/v1/cs/configs
|
|
|
|
|
|
|
|
|
|
|
|
{
|
|
|
|
|
|
"tenantId": "common",
|
|
|
|
|
|
"itemId": "message-center",
|
|
|
|
|
|
"tpId": "custom-pool",
|
|
|
|
|
|
"coreSize": 10,
|
|
|
|
|
|
"maxSize": 15,
|
|
|
|
|
|
"queueType": 9,
|
|
|
|
|
|
"capacity": 9,
|
|
|
|
|
|
"keepAliveTime": 100,
|
|
|
|
|
|
"rejectedType": 7,
|
|
|
|
|
|
"isAlarm": 2,
|
|
|
|
|
|
"capacityAlarm": 80,
|
|
|
|
|
|
"livenessAlarm": 80
|
|
|
|
|
|
}
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
<br/>
|
|
|
|
|
|
|
|
|
|
|
|
接口调用成功后，观察 example 控制台日志输出，日志输出包括不限于此信息即为成功
|
