### DefaultDataBinderFactory

    public DefaultDataBinderFactory(WebBindingInitializer initializer)

  Create new instance.

  Parameters:
    `initializer` - for global data binder intialization, or `null`

Method Detail

### createBinder

    public final WebDataBinder createBinder(NativeWebRequest webRequest,
                                            Object target,
                                            String objectName)
                                     throws Exception

  Create a new `WebDataBinder` for the given target object and initialize it through a `WebBindingInitializer`.

  Specified by:
    `createBinder` in interface `WebDataBinderFactory`
  Parameters:
    `webRequest` - the current request
    `target` - the object to create a data binder for, or `null` if creating a binder for a simple type
    `objectName` - the name of the target object
  Returns:
    the created `WebDataBinder` instance, never null
  Throws:
    `Exception` - in case of invalid state or arguments

### createBinderInstance

    protected WebDataBinder createBinderInstance(Object target,
                                                 String objectName,
                                                 NativeWebRequest webRequest)
                                          throws Exception

  Extension point to create the WebDataBinder instance. By default this is `WebRequestDataBinder`.

  Parameters:
    `target` - the binding target or `null` for type conversion only
    `objectName` - the binding target object name
    `webRequest` - the current request
  Throws:
    `Exception` - in case of invalid state or arguments

### initBinder

    protected void initBinder(WebDataBinder dataBinder,
                              NativeWebRequest webRequest)
                       throws Exception

  Extension point to further initialize the created data binder instance (e.g. with `@InitBinder` methods) after "global" initializaton via `WebBindingInitializer`.

  Parameters:
    `dataBinder` - the data binder instance to customize
    `webRequest` - the current request
  Throws:
    `Exception` - if initialization fails
