`void`	`handleReturnValue(Object returnValue, MethodParameter returnType, ModelAndViewContainer mavContainer, NativeWebRequest webRequest)`	Handle the given return value by adding attributes to the model and setting a view or setting the `ModelAndViewContainer.setRequestHandled(boolean)` flag to `true` to indicate the response has been handled directly.
`boolean`	`isAsyncReturnValue(Object returnValue, MethodParameter returnType)`	Whether the given return value represents asynchronous computation.
`boolean`	`supportsReturnType(MethodParameter returnType)`	Whether the given method return type is supported by this handler.

@Deprecated
public Map<Class<?>,ResponseBodyEmitterAdapter> getAdapterMap()
```
    已过时。
    in 4.3.8, see comments on ResponseBodyEmitterAdapter
    Return the map with ResponseBodyEmitter adapters. By default the map contains a single adapter ResponseBodyEmitter that simply downcasts the return value.
    返回:
    the map of adapters
  - supportsReturnType
```
public boolean supportsReturnType(MethodParameter returnType)
```
    从接口复制的说明: HandlerMethodReturnValueHandler
    Whether the given method return type is supported by this handler.
    指定者:
    supportsReturnType 在接口中 HandlerMethodReturnValueHandler
    参数:
    returnType - the method return type to check
    返回:
    true if this handler supports the supplied return type; false otherwise
  - isAsyncReturnValue
```
public boolean isAsyncReturnValue(Object returnValue,
                                  MethodParameter returnType)
```
    从接口复制的说明: AsyncHandlerMethodReturnValueHandler
    Whether the given return value represents asynchronous computation.
    指定者:
    isAsyncReturnValue 在接口中 AsyncHandlerMethodReturnValueHandler
    参数:
    returnValue - the value returned from the handler method
    returnType - the return type
    返回:
    true if the return value type represents an async value
  - handleReturnValue
```
public void handleReturnValue(Object returnValue,
                              MethodParameter returnType,
                              ModelAndViewContainer mavContainer,
                              NativeWebRequest webRequest)
                       throws Exception
```
    从接口复制的说明: HandlerMethodReturnValueHandler
    Handle the given return value by adding attributes to the model and setting a view or setting the ModelAndViewContainer.setRequestHandled(boolean) flag to true to indicate the response has been handled directly.
    指定者:
    handleReturnValue 在接口中 HandlerMethodReturnValueHandler
    参数:
    returnValue - the value returned from the handler method
    returnType - the type of the return value. This type must have previously been passed to HandlerMethodReturnValueHandler.supportsReturnType(org.springframework.core.MethodParameter) which must have returned true.
    mavContainer - the ModelAndViewContainer for the current request
    webRequest - the current request
    抛出:
    Exception - if the return value handling results in an error
