篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了动态线程池Dinamic-Tp（接入篇）相关的知识，希望对你有一定的参考价值。
这世界上没有优秀的理念，只有脚踏实地的结果 。

前言
DynamicTp项目地址：
gitee地址：https://gitee.com/dromara/dynamic-tp
github地址：https://github.com/dromara/dynamic-tp
本文主要讲一下怎么接入dynamic-tp
一、配置中心
后续我们以spring boot 集成 nacos 应用接入为例。
提示
动态线程池配置文件，建议单独开一个文件放在 nacos 中，如：user-center-dtp-dev.yml
如果配置中心支持 yml 格式，建议最好使用 yml 文件配置，可读性、可操作性更友好
给出的是全配置项，使用不到的项或者使用默认值的项都可以删除，减少配置量
集成失败 90% 以上情况都是使用姿势有误 / 版本兼容问题，有版本兼容性问题可以提 Issues 或加群反馈。
nacos-config-spring-boot-starter 0.2.10 及以下版本对应 springboot 2.3.12.RELEASE 及以下版本
0.2.11-beta 及以上版本对应 springboot 版本 2.4.0 及以上版本，具体看官方说明
二、maven 依赖
<dependency>
<groupId>cn.dynamictp</groupId>
<artifactId>dynamic-tp-spring-boot-starter-nacos</artifactId>
<version>1.1.0</version>
</dependency>三、线程池配置文件
3.1 yml 格式
spring:
dynamic:
tp:
enabled: true
enabledCollect: true # 是否开启监控指标采集，默认false
collectorTypes: micrometer,logging # 监控数据采集器类型（logging | micrometer | internal_logging），默认micrometer
logPath: /home/logs # 监控日志数据路径，默认 $user.home/logs，采集类型非logging不用配置
monitorInterval: 5 # 监控时间间隔（报警检测、指标采集），默认5s
nacos: # nacos配置，不配置有默认值（user-center-dev.yml这样）
dataId: dynamic-tp-demo-dev.yml # 该配置文件的 dataId，如上述 user-center-dtp-dev.yml
group: DEFAULT_GROUP
configType: yml # 配置文件类型
platforms: # 通知报警平台配置
- platform: wechat
urlKey: 3a700-127-4bd-a798-c53d8b69c # 替换
receivers: test1,test2 # 接受人企微名称
- platform: ding
urlKey: f80dad441fcd655438f4a08dcd6a # 替换
secret: SECb5441fa6f375d5b9d21 # 替换，非sign模式可以没有此值
receivers: 18888888888 # 钉钉账号手机号
- platform: lark
urlKey: 0d944ae7-b24a-40 # 替换
receivers: test1,test2 # 接受人飞书名称/openid
- platform: email
receivers: 123456@qq.com,789789@qq.com # 收件人
executors: # 动态线程池配置，都有默认值，采用默认值的可以不配置该项，减少配置量
- threadPoolName: dtpExecutor1
threadPoolAliasName: 测试线程池 # 线程池别名
executorType: common # 线程池类型common、eager：适用于io密集型
corePoolSize: 6
maximumPoolSize: 8
queueCapacity: 200
queueType: VariableLinkedBlockingQueue # 任务队列，查看源码QueueTypeEnum枚举类
rejectedHandlerType: CallerRunsPolicy # 拒绝策略，查看RejectedTypeEnum枚举类
keepAliveTime: 50
allowCoreThreadTimeOut: false # 是否允许核心线程池超时
threadNamePrefix: test # 线程名前缀
waitForTasksToCompleteOnShutdown: false # 参考spring线程池设计，优雅关闭线程池
awaitTerminationSeconds: 5 # 单位（s）
preStartAllCoreThreads: false # 是否预热所有核心线程，默认false
runTimeout: 200 # 任务执行超时阈值，目前只做告警用，单位（ms）
queueTimeout: 100 # 任务在队列等待超时阈值，目前只做告警用，单位（ms）
taskWrapperNames: ["ttl", "mdc"] # 任务包装器名称，继承TaskWrapper接口
notifyEnabled: true # 是否开启报警，默认true
notifyItems: # 报警项，不配置自动会按默认值配置（变更通知、容量报警、活性报警、拒绝报警、任务超时报警）
- type: capacity # 报警项类型，查看源码 NotifyTypeEnum枚举类
enabled: true
threshold: 80 # 报警阈值
platforms: [ding,wechat] # 可选配置，不配置默认拿上层platforms配置的所以平台
interval: 120 # 报警间隔（单位：s）
- type: change
enabled: true
- type: liveness
enabled: true
threshold: 80
- type: reject
enabled: true
threshold: 1
- type: run_timeout
enabled: true
threshold: 1
- type: queue_timeout
enabled: true
threshold: 1

4.2 启动类添加@EnableDynamicTp注解
@EnableDynamicTp
@SpringBootApplication
public class DynamicApplication
public static void main(String[] args)
SpringApplication.run(DynamicApplication.class, args);
4.3 添加一个线程池配置文件
package com.dzw.dynamic;
import com.dtp.common.em.QueueTypeEnum;
import com.dtp.common.em.RejectedTypeEnum;
import com.dtp.core.support.ThreadPoolBuilder;
import com.dtp.core.support.ThreadPoolCreator;
import com.dtp.core.thread.DtpExecutor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;
/**
* @Description Description
* @Author lyb
* @Date Created in 2023/2/3
*/
@Configuration
public class ThreadPoolConfiguration
@Bean
public DtpExecutor dtpExecutor()
return ThreadPoolCreator.createDynamicFast("dynamic-tp-test-1");
@Bean
public ThreadPoolExecutor dynamicExecutor()
return ThreadPoolBuilder.newBuilder()
.threadPoolName("dynamicExecutor")
.corePoolSize(2)
.maximumPoolSize(2)
.keepAliveTime(6000L)
.timeUnit(TimeUnit.MILLISECONDS)
.workQueue(QueueTypeEnum.ARRAY_BLOCKING_QUEUE.getName(), 2, true)
.rejectedExecutionHandler(RejectedTypeEnum.DISCARD_POLICY.getName())
.buildDynamic();
@Bean
public ThreadPoolExecutor dynamicExecutor2()
return ThreadPoolBuilder.newBuilder()
.threadPoolName("dynamicExecutor2")
.corePoolSize(2)
.maximumPoolSize(2)
.keepAliveTime(6000L)
.timeUnit(TimeUnit.MILLISECONDS)
.workQueue(QueueTypeEnum.ARRAY_BLOCKING_QUEUE.getName(), 2, true)
.rejectedExecutionHandler(RejectedTypeEnum.DISCARD_POLICY.getName())
.buildDynamic();
4.4 写一个测试接口
package com.dzw.dynamic;
import com.dtp.core.DtpRegistry;
import com.dtp.core.thread.DtpExecutor;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.concurrent.ThreadPoolExecutor;
/**
* @Description Description
* @Author lyb
* @Date Created in 2023/2/3
*/
@Slf4j
@RestController
public class TestController
@Autowired
private ThreadPoolExecutor dynamicExecutor;
/**
* @Description: 测试自定义线程池
* @Author: lyb
* @Date: 2023/2/6 11:18 上午
* @Version: 1.0
* @Return:
*/
@GetMapping("/thread/customize/test")
public String customizeTest()
new Thread(() ->
try
task();
catch (InterruptedException e)
e.printStackTrace();
).start();
return "success";
public void task() throws InterruptedException
// DtpExecutor threadPoolExecutor = DtpRegistry.getDtpExecutor("dynamicExecutor");
for (int i = 0; i < 100; i++)
dynamicExecutor.execute(() ->
try
log.info("i am dynamic-tp-test-2 task");
Thread.sleep(2000);
catch (InterruptedException e)
e.printStackTrace();
);
/**
* @Description: 测试undertow线程池
* @Author: lyb
* @Date: 2023/2/6 11:22 上午
* @Version: 1.0
* @Return:
*/
@GetMapping("/thread/undertow/test")
public String undertowTest()
try
Thread.sleep(10000L);
catch (InterruptedException e)
e.printStackTrace();
return "success";
