```
public StandardServletAsyncWebRequest(HttpServletRequest request,
                                      HttpServletResponse response)
```
    Create a new instance for the given request/response pair.
    参数:
    request - current HTTP request
    response - current HTTP response
- 方法详细资料
  - setTimeout
```
public void setTimeout(Long timeout)
```
    In Servlet 3 async processing, the timeout period begins after the container processing thread has exited.
    指定者:
    setTimeout 在接口中 AsyncWebRequest
    参数:
    timeout - amount of time in milliseconds; null means no timeout, i.e. rely on the default timeout of the container.
  - addTimeoutHandler
```
public void addTimeoutHandler(Runnable timeoutHandler)
```
    从接口复制的说明: AsyncWebRequest
    Add a handler to invoke when concurrent handling has timed out.
    指定者:
    addTimeoutHandler 在接口中 AsyncWebRequest
  - addErrorHandler
```
public void addErrorHandler(Consumer<Throwable> exceptionHandler)
```
    从接口复制的说明: AsyncWebRequest
    Add a handler to invoke when an error occurred while concurrent handling of a request.
    指定者:
    addErrorHandler 在接口中 AsyncWebRequest
  - addCompletionHandler
```
public void addCompletionHandler(Runnable runnable)
```
    从接口复制的说明: AsyncWebRequest
    Add a handler to invoke when request processing completes.
    指定者:
    addCompletionHandler 在接口中 AsyncWebRequest
  - isAsyncStarted
```
public boolean isAsyncStarted()
```
    从接口复制的说明: AsyncWebRequest
    Whether the request is in async mode following a call to AsyncWebRequest.startAsync(). Returns "false" if asynchronous processing never started, has completed, or the request was dispatched for further processing.
    指定者:
    isAsyncStarted 在接口中 AsyncWebRequest
  - isAsyncComplete
```
public boolean isAsyncComplete()
```
    Whether async request processing has completed.
    It is important to avoid use of request and response objects after async processing has completed. Servlet containers often re-use them.
    指定者:
    isAsyncComplete 在接口中 AsyncWebRequest
  - startAsync
```
public void startAsync()
```
    从接口复制的说明: AsyncWebRequest
    Mark the start of asynchronous request processing so that when the main processing thread exits, the response remains open for further processing in another thread.
    指定者:
    startAsync 在接口中 AsyncWebRequest
  - dispatch
```
public void dispatch()
```
    从接口复制的说明: AsyncWebRequest
    Dispatch the request to the container in order to resume processing after concurrent execution in an application thread.
    指定者:
    dispatch 在接口中 AsyncWebRequest
  - onStartAsync
```
public void onStartAsync(AsyncEvent event)
                  throws IOException
```
    从接口复制的说明: javax.servlet.AsyncListener
    Notifies this AsyncListener that a new asynchronous cycle is being initiated via a call to one of the ServletRequest.startAsync() methods.
    The AsyncContext corresponding to the asynchronous operation that is being reinitialized may be obtained by calling getAsyncContext on the given event.
    In addition, if this AsyncListener had been registered via a call to AsyncContext.addListener(AsyncListener, ServletRequest, ServletResponse), the supplied ServletRequest and ServletResponse objects may be retrieved by calling getSuppliedRequest and getSuppliedResponse, respectively, on the given event.
    This AsyncListener will not receive any events related to the new asynchronous cycle unless it registers itself (via a call to AsyncContext.addListener(javax.servlet.AsyncListener)) with the AsyncContext that is delivered as part of the given AsyncEvent.
    指定者:
    onStartAsync 在接口中 AsyncListener
    参数:
    event - the AsyncEvent indicating that a new asynchronous cycle is being initiated
    抛出:

             throws IOException
```
    从接口复制的说明: javax.servlet.AsyncListener

               throws IOException

    从接口复制的说明: javax.servlet.AsyncListener
    Notifies this AsyncListener that an asynchronous operation has timed out.
    The AsyncContext corresponding to the asynchronous operation that has timed out may be obtained by calling getAsyncContext on the given event.
    In addition, if this AsyncListener had been registered via a call to AsyncContext.addListener(AsyncListener, ServletRequest, ServletResponse), the supplied ServletRequest and ServletResponse objects may be retrieved by calling getSuppliedRequest and getSuppliedResponse, respectively, on the given event.
    指定者:
    onTimeout 在接口中 AsyncListener
    参数:
    event - the AsyncEvent indicating that an asynchronous operation has timed out
    抛出:
