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
