异步线程实现简单实现方式@Async

初始化配置EnableAsync

import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.task.AsyncTaskExecutor;
import org.springframework.scheduling.annotation.AsyncConfigurer;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

import java.util.concurrent.ThreadPoolExecutor;

@Configuration
@EnableAsync
public class TheadPoolConfig implements AsyncConfigurer {
    @Value("${ThreadPoolConfig.corePoolSize:50}")
    private int coreSize;

    @Value("${ThreadPoolConfig.maxPoolSize:200}")
    private int maxSize;

    @Value("${ThreadPoolConfig.queueCapacity:100}")
    private int queueCapacity;

    @Value("${ThreadPoolConfig.keepAlive:100}")
    private int keepAliveSeconds;

    @Value("${ThreadPoolConfig.otherCoreSize:50}")
    private int otherCoreSize;
    @Value("${ThreadPoolConfig.otherMaxPoolSize:200}")
    private int otherMaxSize;

    @Value("${ThreadPoolConfig.otherQueueCapacity:100}")
    private int otherQueueCapacity;

    @Value("${ThreadPoolConfig.otherKeepAlive:100}")
    private int otherKeepAliveSeconds;



    @Bean("asyncThreadPool")
    public AsyncTaskExecutor taskExecutor1() {
        //使用Spring内置线程池任务对象
        ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor();
        //设置线程池参数
        taskExecutor.setThreadNamePrefix("asyncThreadPool-");
        taskExecutor.setCorePoolSize(coreSize);
        taskExecutor.setMaxPoolSize(maxSize);
        taskExecutor.setQueueCapacity(queueCapacity);
        taskExecutor.setKeepAliveSeconds(keepAliveSeconds);
        taskExecutor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        taskExecutor.initialize();
        return taskExecutor;
    }


}

使用

    @Async("asyncThreadPool")
    public void updateHotelPriceMap(String hotelId) {

}
