Schema

Example schema definition input-schema.properties

# KEY = <length-of-field>
id=2
codFiscale=16
sequence=16
number=10
FILLER_1=4
date=10
FILLER_2=4
Note=22

or if you want use custom model class with annotation

public class ModelMap {

   @Definition(name="id", size=2)
   private String id ;

   @Definition(name="codiceFiscale", size=16)
   private String codiceFiscale ;

   @Definition(name="sequence", size=12)
   private String sequence ;

   @Definition(name="number", size=10)
   private String number ;

   @Definition(size=4)
   private Filler filler ;

   @Definition(name="date", size=10)
   private String date ;

   @Definition(size=4)
   private Filler filler2 ;

   @Definition(name="note", size=6)
   private Filler note ;

}

Read

reading input.txt file

01ABCDFGHILMNOPQR99999999999991234567890    18/04/2019    NOTE 1

public static void main(String...args) throws IOException {

   String inputFile = "input.txt";

   RecordFileReader recorFileReader = new RecordFileReader(inputFile, ModelMap.class);

   for(Map element: recorFileReader.getElements()) {
		System.out.print(element);
   }

}

Result Map

{
	date=4/2019, 
	sequence=9999999999991234, 
	number=567890, 
	codFiscale=ABCDFGHILMNOPQR9, 
	id=01
}

Write

public static void main(String...args) throws IOException {
  
    String outputFile = "out.txt";

    Map<String,String> elements = new HashMap<>();

    elements.put("id","01");
    elements.put("codiceFiscale","ABCDFGHILMNOPQR9");
    elements.put("sequence","9999999999991234");
    elements.put("number","567890");
    elements.put("date","2019");
    elements.put("note","asd");

    RecorFileWriter recorFileWriter = new RecorFileWriter(outputFile, ModelMap.class);
    recorFileWriter.write(Arrays.asList(elements));

}

Note

By default RecorFileReader loocking for input-schema.properties file in resource folder but you can pass as parameter

File name of your schema
Directly the Properties object
.class of your custom entity

Like RecorFileReader also RecorFileWriter loocking for output-schema.properties or input-schema.properties else you can pass as parameter

File name of your schema
Directly the Properties object
.class of your custom entity
