**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)
<br/>
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DTPDynamic 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/>

<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
<br/>
