Multithreading Spring延迟结果&；在web筛选器中请求作用域bean（Oauth2ClientContext）

从我的控制器返回另一个线程填充的延迟结果：

FooController.java

@RequestMapping("/deferred")
public DeferredResult<String> deferred() throws InterruptedException, ExecutionException{
    DeferredResult<String> deferred = new DeferredResult<>();
    pagePreparer.setResult(deferred);
    return deferred;
}

查看我配置的异常：

@Bean
public RequestContextListener requestContextListener(){
    return new RequestContextListener();
}

---

但是没有区别。如何解决这个问题？

事实证明，您必须执行以下操作：

@Bean
public FilterRegistrationBean requestContextFilterRegistration(){
    FilterRegistrationBean filter = new FilterRegistrationBean();
    filter.setFilter(requestContextFilter());
    filter.setOrder(0);
    return filter;
}

@Bean
public RequestContextFilter requestContextFilter(){
    return new RequestContextFilter();
}

@Bean
public RequestContextListener requestContextListener(){
    return new RequestContextListener();
}

@Bean
public FilterRegistrationBean requestContextFilterRegistration(){
    FilterRegistrationBean filter = new FilterRegistrationBean();
    filter.setFilter(requestContextFilter());
    filter.setOrder(0);
    return filter;
}

@Bean
public RequestContextFilter requestContextFilter(){
    return new RequestContextFilter();
}
