springboot创建线程池的方法

我只用到了其中几项，在application.yml配置文件

threadpool:
  # 核心线程池数（根据自身电脑cpu核数*2+1）（但是考虑通用性，以及使用时的感受在此设置5）
  corePoolSize: 5
  #最大线程
  maxPoolSize: 10
  #队列容量（满了的时候，排队的长度）
  queueCapacity: 1000

如下是项目所引入的完整代码

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

import java.util.concurrent.Executor;
import java.util.concurrent.ThreadPoolExecutor;

@Configuration
@EnableAsync
@ConfigurationProperties(prefix = "threadpool")
@PropertySource(name = "application.yml", value = {"classpath:/application.yml"})
public class ExecutorConfig {
    @Value("${corePoolSize}")
    private int corePoolSize;

    @Value("${maxPoolSize}")
    private int maxPoolSize;

    @Value("${queueCapacity}")
    private int queueCapacity;

    @Bean(name = "taskExecutor")
    public Executor asynsServiceExecutor(){
        ThreadPoolTaskExecutor threadPoolTaskExecutor = new ThreadPoolTaskExecutor();
        threadPoolTaskExecutor.setCorePoolSize(corePoolSize);
        threadPoolTaskExecutor.setMaxPoolSize(maxPoolSize);
        threadPoolTaskExecutor.setQueueCapacity(queueCapacity);

        threadPoolTaskExecutor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        threadPoolTaskExecutor.initialize();
        return threadPoolTaskExecutor;
    }
}

如果当你的配置文件可以自动搜索到上述配置文件的内容，可以把注释中的下面代码去掉

@PropertySource(name = "application.yml", value = {"classpath:/application.yml"})

一般线程代码都是从controller层使用，下面是引入的代码，service层不动

	@Resource(name = "taskExecutor")
    private Executor taskExecutor;

		//控制层接入service层的入口
    	taskExecutor.execute(()->{
                try {
                    //service方法
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            });
