public class StandardServletAsyncWebRequest extends ServletWebRequest implements AsyncWebRequest, AsyncListener
A Servlet 3.0 implementation ofAsyncWebRequest
.The servlet and all filters involved in an async request must have async support enabled using the Servlet API or by adding an
<async-supported>true</async-supported>
element to servlet and filter declarations inweb.xml

构造器详细资料
StandardServletAsyncWebRequest
public StandardServletAsyncWebRequest(HttpServletRequest request, HttpServletResponse response)
Create a new instance for the given request/response pair.- 参数:
request
- current HTTP requestresponse
- 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
addCompletionHandler
public void addCompletionHandler(Runnable runnable)
从接口复制的说明:AsyncWebRequest
Add a handle 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 toAsyncWebRequest.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
- 指定者:
onStartAsync
在接口中AsyncListener
- 抛出:
IOException
onError
public void onError(AsyncEvent event) throws IOException
- 指定者:
onError
在接口中AsyncListener
- 抛出:
IOException
onTimeout
public void onTimeout(AsyncEvent event) throws IOException
- 指定者:
onTimeout
在接口中AsyncListener
- 抛出:
IOException
onComplete
public void onComplete(AsyncEvent event) throws IOException
- 指定者:
onComplete
在接口中AsyncListener
- 抛出:
IOException
