Java Future – Spring Authentication在AuditorAware中为null

这是我的情景：

我的应用程序启用了Mongo审核,使用自定义AuditorAware从SecurityContext获取当前用户.这适用于同步方法,并且成功保存了当前审计员,但我无法使用@Async方法使其正常工作.

我有一个异步方法(CompletableFuture),它在我的Mongo数据库上进行了一些更新.调用AuditorAware.getCurrentAuditor()时,不存在身份验证信息,我无法获取当前审计员(SecurityContextHolder.getContext().getAuthentication()返回null).

@Override
public User getCurrentAuditor() {
   Authentication authentication = SecurityContextHolder.getContext().getAuthentication();

   if (authentication == null || !authentication.isAuthenticated()
                || authentication instanceof AnonymousAuthenticationToken) {
            log.error("Not authenticated");
            return null;
    }

    [...]

}

我正在使用DelegatingSecurityContextAsyncTaskExecutor：

@Configuration
@EnableAsync
public class AsyncConfig implements AsyncConfigurer {

    @Override
    public Executor getAsyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(20);
        executor.setMaxPoolSize(100);
        executor.setQueueCapacity(200);
        executor.initialize();

        return new DelegatingSecurityContextAsyncTaskExecutor(executor);
    }

    @Override
    public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
        return new itacaExceptionHandler();
    }

} 

我怎样才能让它正常工作？

解决方法:

Spring安全上下文始终绑定到Threadlocal.

也可以为安全上下文另外设置MODE_INHERITABLETHREADLOCAL.

@Bean
public MethodInvokingfactorybean methodInvokingfactorybean() {
    MethodInvokingfactorybean methodInvokingfactorybean = new MethodInvokingfactorybean();
    methodInvokingfactorybean.setTargetClass(SecurityContextHolder.class);
    methodInvokingfactorybean.setTargetmethod("setStrategyName");
    methodInvokingfactorybean.setArguments(new String[]{SecurityContextHolder.MODE_INHERITABLETHREADLOCAL});
    return methodInvokingfactorybean;
}
