- org.springframework.http.client.Netty4ClientHttpRequestFactory

All Implemented Interfaces:
DisposableBean, InitializingBean, AsyncClientHttpRequestFactory, ClientHttpRequestFactory
```
public class Netty4ClientHttpRequestFactory
extends Object
implements ClientHttpRequestFactory, AsyncClientHttpRequestFactory, InitializingBean, DisposableBean
```
ClientHttpRequestFactory implementation that uses Netty 4 to create requests.
Allows to use a pre-configured EventLoopGroup instance: useful for sharing across multiple clients.
Note that this implementation consistently closes the HTTP connection on each request.
Since:
4.1.2

- Field Detail
  - DEFAULT_MAX_RESPONSE_SIZE
```
public static final int DEFAULT_MAX_RESPONSE_SIZE
```
    The default maximum response size.

    setMaxResponseSize(int), Constant Field Values
- Constructor Detail
  - Netty4ClientHttpRequestFactory
```
public Netty4ClientHttpRequestFactory()
```
    Create a new Netty4ClientHttpRequestFactory with a default NioEventLoopGroup.
  - Netty4ClientHttpRequestFactory
```
public Netty4ClientHttpRequestFactory(io.netty.channel.EventLoopGroup eventLoopGroup)
```
    Create a new Netty4ClientHttpRequestFactory with the given EventLoopGroup.
    NOTE: the given group will not be shutdown by this factory; doing so becomes the responsibility of the caller.

  - setMaxResponseSize
```
public void setMaxResponseSize(int maxResponseSize)
```
    Set the default maximum response size.
    By default this is set to DEFAULT_MAX_RESPONSE_SIZE.
    Since:
    4.1.5
    See Also:
    HttpObjectAggregator(int)
  - setSslContext
```
public void setSslContext(io.netty.handler.ssl.SslContext sslContext)
```
    Set the SSL context. When configured it is used to create and insert an SslHandler in the channel pipeline.
    A default client SslContext is configured if none has been provided.
  - setConnectTimeout
```
public void setConnectTimeout(int connectTimeout)
```
    Set the underlying connect timeout (in milliseconds). A timeout value of 0 specifies an infinite timeout.
    See Also:
    ChannelConfig.setConnectTimeoutMillis(int)
  - setReadTimeout
```
public void setReadTimeout(int readTimeout)
```
    Set the underlying URLConnection's read timeout (in milliseconds). A timeout value of 0 specifies an infinite timeout.
    See Also:
    ReadTimeoutHandler
  - afterPropertiesSet
```
public void afterPropertiesSet()
```
    Description copied from interface: InitializingBean
    Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.
    This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
    Specified by:
    afterPropertiesSet in interface InitializingBean
  - createRequest
```
public ClientHttpRequest createRequest(URI uri,
                                       HttpMethod httpMethod)
                                throws IOException
```
    Description copied from interface: ClientHttpRequestFactory
    Create a new ClientHttpRequest for the specified URI and HTTP method.
    The returned request can be written to, and then executed by calling ClientHttpRequest.execute().
    Specified by:
    createRequest in interface ClientHttpRequestFactory
    Parameters:
    uri - the URI to create a request for
    httpMethod - the HTTP method to execute
    Returns:
    the created request
    Throws:
    IOException - in case of I/O errors
  - createAsyncRequest
```
public AsyncClientHttpRequest createAsyncRequest(URI uri,
                                                 HttpMethod httpMethod)
                                          throws IOException
```
    Description copied from interface: AsyncClientHttpRequestFactory
    Create a new asynchronous AsyncClientHttpRequest for the specified URI and HTTP method.
    The returned request can be written to, and then executed by calling AsyncClientHttpRequest.executeAsync().
    Specified by:
    createAsyncRequest in interface AsyncClientHttpRequestFactory
    Parameters:
    uri - the URI to create a request for
    httpMethod - the HTTP method to execute
    Returns:
    the created request
    Throws:
    IOException - in case of I/O errors
  - configureChannel
```
protected void configureChannel(io.netty.channel.socket.SocketChannelConfig config)
```
    Template method for changing properties on the given SocketChannelConfig.
    The default implementation sets the connect timeout based on the set property.
    Parameters:
    config - the channel configuration
  - destroy
```
public void destroy()
             throws InterruptedException
```
    Description copied from interface: DisposableBean
    Invoked by the containing BeanFactory on destruction of a bean.
    Specified by:
    destroy in interface DisposableBean
    Throws:
    InterruptedException
