Examples of org.springframework.web.bind.ServletRequestDataBinder.bind()

org.springframework.web.bind.ServletRequestDataBinder.bind()
Bind the parameters of the given request to this binder's target, also binding multipart files in case of a multipart request.
This call can create field errors, representing basic binding errors like a required field (code "required"), or type mismatch between value and bean property (code "typeMismatch").
Multipart files are bound via their parameter name, just like normal HTTP parameters: i.e. "uploadedFile" to an "uploadedFile" bean property, invoking a "setUploadedFile" setter method.
The type of the target property for a multipart file can be MultipartFile, byte[], or String. The latter two receive the contents of the uploaded file; all metadata like original file name, content type, etc are lost in those cases. @param request request with parameters to bind (can be multipart) @see org.springframework.web.multipart.MultipartHttpServletRequest @see org.springframework.web.multipart.MultipartFile @see #bindMultipartFiles @see #bind(org.springframework.beans.PropertyValues)
