Description

This sub-element formatter is used into the decoding of client request's parameters in order to create the input for a GreenVulcano® ESB service and to convert the service's output into a HTTP response.


GreenVulcano® ESB Configuration

The GVAdapterHttpConfiguration Element is used by: GVAdapters.

The following table shows the ExtendedInboundParamHandlerFormatter attributes:

Attribute Type Description
type fixed Set to FormatterPlugin.
class fixed Set to it.greenvulcano.gvesb.adapter.http.formatters.handlers.ExtendedInboundParamHandlerFormatter.
ID required Formatter identifier
read-request-header optional If 'true' reads the request HTTP headers and provide them with the request parameters. Default value is false.
ReqCharacterEncoding optional CharacterEncoding to be used to handle requests from external system. Default to UTF-8.
RespCharacterEncoding optional CharacterEncoding to handle responses to the external system. Default to UTF-8.
RespContentType optional ContentType to be declared while handling HTTP responses to the external system. Default to text/html.
HandlePostBodyAsParams optional If true force the POST body to be handled as application/x-www-form-urlencoded content type. Default is false.
ResponseOnError-HTTPCode optional If != -1 force the adapter to respond with the given http code on case of error. Default is -1 (disabled).

Contains the sub-elements:
