问题
From my controller I'm returning deferred result which is filled by another thread:
FooController.java
@RequestMapping("/deferred")
public DeferredResult<String> deferred() throws InterruptedException, ExecutionException{
DeferredResult<String> deferred = new DeferredResult<>();
pagePreparer.setResult(deferred);
return deferred;
}
PagePreparer.java
@Async
public void setResult(DeferredResult<String> result){
try {
logger.debug("Execute method asynchronously - " + Thread.currentThread().getName());
Thread.sleep(2000l);
result.setResult("deferred");
} catch (InterruptedException e) {
e.printStackTrace();
}
}
Apparently DeferredResult calls all the filters again to "finalize" the request. One of my filter, needs to access oauth2ClientContext bean, which is request scoped. That call is throwing an exception

Looking at the exception I've configured:
@Bean
public RequestContextListener requestContextListener(){
return new RequestContextListener();
}
But there's no difference. How can I solve this?
回答1:
Actually it turns out, you have to do the following:
@Bean
public FilterRegistrationBean requestContextFilterRegistration(){
FilterRegistrationBean filter = new FilterRegistrationBean();
filter.setFilter(requestContextFilter());
filter.setOrder(0);
return filter;
}
@Bean
public RequestContextFilter requestContextFilter(){
return new RequestContextFilter();
}
