Question

Hi I have am trying to implement a file upload in my application where the file uploaded is parsed and an entry is created in the database using that information.

 def save = {

        def file = request.getFile("file");
        def filename = file.getOriginalFilename();
        def type = filename.split('\\.');

        if(!file.isEmpty()){
            if(type[1] == "properties"){

                redirect(action:"parsePropertyFile", params:params);
            }
        }
 }

def parsePropertyFile = {

      println "\n"
      println params.file;
      println "\n";

      def f = params.file;
      println f;

      def filename = f.getOriginalFilename();
      println filename;
}

when I print out f this is output:

org.springframework.web.multipart.commons.CommonsMultipartFile@29d32df9

but when I try to call getOriginalFilename() on f I get the following error:

groovy.lang.MissingMethodException: No signature of method: 
java.lang.String.getOriginalFilename() is applicable for argument types: () values: []

I also printed out file from the save function and the output of that is also:

org.springframework.web.multipart.commons.CommonsMultipartFile@29d32df9

so why am I getting the error?

Answer 1

Instead of redirecting, can you just call your another function? Redirect will issue an http redirect with the file as param with no need.

if(type[1] == "properties") {
  parsePropertyFile(file)
}

And then:

private def parsePropertyFile(def file) {
  String filename = file.getOriginalFilename();
  ...
}
