springboot线程池配置核心参数

@Configuration
@EnableAsync
public class TaskExecutorConfig {

    @Bean
    public TaskExecutor taskExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();

        // 设置核心线程数
        executor.setCorePoolSize(10);
        // 设置最大线程数
        executor.setMaxPoolSize(20);
        // 设置队列容量
        executor.setQueueCapacity(Integer.MAX_VALUE);
        // 设置线程活跃时间（秒）
        executor.setKeepAliveSeconds(120);
        // 设置默认线程名称
        executor.setThreadNamePrefix("member-thread");
        // 设置拒绝策略
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());

        return executor;
    }
