所有方法实例方法抽象方法
修饰符和类型	方法	说明
`void`	`addCompletionHandler(Runnable runnable)`	Add a handle to invoke when request processing completes.
`void`	`addTimeoutHandler(Runnable runnable)`	Add a handler to invoke when concurrent handling has timed out.
`void`	`dispatch()`	Dispatch the request to the container in order to resume processing after concurrent execution in an application thread.
`boolean`	`isAsyncComplete()`	Whether asynchronous processing has completed.
`boolean`	`isAsyncStarted()`	Whether the request is in async mode following a call to `startAsync()`.
`void`	`setTimeout(Long timeout)`	Set the time required for concurrent handling to complete.
`void`	`startAsync()`	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.

  - setTimeout
```
void setTimeout(Long timeout)
```
    Set the time required for concurrent handling to complete. This property should not be set when concurrent handling is in progress, i.e. when isAsyncStarted() is true.
    参数:
    timeout - amount of time in milliseconds; null means no timeout, i.e. rely on the default timeout of the container.
  - addTimeoutHandler
```
void addTimeoutHandler(Runnable runnable)
```
    Add a handler to invoke when concurrent handling has timed out.
  - addCompletionHandler
```
void addCompletionHandler(Runnable runnable)
```
    Add a handle to invoke when request processing completes.
  - startAsync
```
void startAsync()
```
    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.
    抛出:
    IllegalStateException - if async processing has completed or is not supported
  - isAsyncStarted
```
boolean isAsyncStarted()
```
    Whether the request is in async mode following a call to startAsync(). Returns "false" if asynchronous processing never started, has completed, or the request was dispatched for further processing.
  - dispatch
```
void dispatch()
```
    Dispatch the request to the container in order to resume processing after concurrent execution in an application thread.
  - isAsyncComplete
```
boolean isAsyncComplete()
```
    Whether asynchronous processing has completed.
