springboot中实现异步方法

开启配置线程池

package org.springblade.auth.config;
 
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
 
import java.util.concurrent.ThreadPoolExecutor;
 
/**
 * 线程池配置
 */
@EnableAsync
@Configuration
public class ThreadPoolTaskConfig {
 
    /**
     * 核心线程数（默认线程数）
     */
    private static final int CORE_POOL_SIZE = 5;
    /**
     * 最大线程数
     */
    private static final int MAX_POOL_SIZE = 10;
    /**
     * 允许线程空闲时间（单位：默认为秒）
     */
    private static final int KEEP_ALIVE_TIME = 5;
    /**
     * 缓冲队列大小
     */
    private static final int QUEUE_CAPACITY = 50;
    /**
     * 线程池名前缀
     */
    private static final String THREAD_NAME_PREFIX = "Async-Service-";
 
    /**
     * bean的名称，默认为首字母小写的方法名
     * 然后在用到的异步方法的地方，显式引用改线程池。
     * 例如@Async("taskExecutor")
     */
    @Bean("taskExecutor")
    public ThreadPoolTaskExecutor taskExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(CORE_POOL_SIZE);
        executor.setMaxPoolSize(MAX_POOL_SIZE);
        executor.setQueueCapacity(QUEUE_CAPACITY);
        executor.setKeepAliveSeconds(KEEP_ALIVE_TIME);
        executor.setThreadNamePrefix(THREAD_NAME_PREFIX);
 
        // 线程池对拒绝任务的处理策略
        // CallerRunsPolicy：由调用线程（提交任务的线程）处理该任务
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        // 初始化
        executor.initialize();
        return executor;
    }
 
}

方法上加上@Async("taskExecutor")注解，在其他业务类中调用就可以实现异步调用
 
        @Override
    @Async("taskExecutor")
    public Boolean updateDoctorOrAssistantRedundanceInfo(BizUpdateDTO dto) {
 
       }
