Let us try to create convert Drools decision table (excel spread sheet) to a (.drl) file in Drools.
The SpreadsheetCompiler class is used to convert the input XLS and CSV file to a (.drl) berkas. The required package is “org.drools.decisiontable.SpreadsheetCompiler”.You need to use the compile () method of this class to do the conversion. Following example shows the processs.
Example program:-
mengimpor java.io.FileInputStream;
impor java.io.FileNotFoundException;
mengimpor java.io.InputStream;
impor org.drools.decisiontable.InputType;
impor org.drools.decisiontable.SpreadsheetCompiler;
public class ExcelToDrlDemo {
public static void main(String args[]) {
// create an input stream
InputStream adalah = null;
coba {
// assign the excel to the input stream
// mention the local directory path where your excel is kept
// you can take any decision table (excel sheet) for testing
adalah = FileInputStream baru(“D:/Workspace/TestProj/src/ExamplePolicyPricing.xls”);
} menangkap (FileNotFoundException e) {
e.printStackTrace();
}
// create compiler class instance
SpreadsheetCompiler sc = new SpreadsheetCompiler();
// compile the excel to generate the (.drl) berkas
String drl=sc.compile(adalah, InputType.XLS);
// check the generated (.drl) berkas
System.out.println(“Generate DRL file is –: “);
System.out.println(drl);
}
}
