use csv file to send post request on rest API

i have a .csv file (having multiple rows and 3 columns). i need to use this data and send JAXB request to invoke client REST API in spring MVC project. client server should not be hard coded we need to form a bean in xml file to use it. we will NOT store this response, using this response need to filter id (suppose one element of xml resopnse) now we will send id as post request to another REST API.
