service使用异步注解

springSecurity 获取认证信息返回null

# 问题原因 #

SpringSecurity 是线程绑定的  异步处理是重新new一个线程进行业务处理

所以说 新线程里是没有 认证信息的

需要重写AsyncConfigurer 使用SpringSecurity 的 装饰线程池 这样就可以携带认证信息了

@Configuration
    public class AsyncConfig extends AsyncConfigurerSupport {
    
        /**
         * 异步执行需要使用权限框架自带的包装线程池  保证权限信息的传递
         */
        @Override
        public Executor getAsyncExecutor() {
            return new DelegatingSecurityContextExecutorService(Executors.newFixedThreadPool(5));
        }
    
    }
