Using transmittablethreadlocal to realize parameter cross thread transmission

1. establish ThreadLocalContext

public class ThreadLocalContext {
    

    public static TransmittableThreadLocal<SystemParams> systemParamsThreadLocal = new TransmittableThreadLocal<>();
}

2. assignment

ThreadLocalContext.systemParamsThreadLocal.set(systemParamsDTO);

3. Thread pool configuration

@Configuration
public class ThreadPoolConfig {
    

    @Bean
    public ExecutorService threadPoolExecutor(){
    
        return  TtlExecutors.getTtlExecutorService(new ThreadPoolExecutor(
                10, 1000,30000L, TimeUnit.SECONDS,
                new LinkedBlockingQueue<Runnable>(2000),
                new CustomizableThreadFactory("thread-pool-"),
                RejectPolicy.ABORT.getValue()));
    }
}
