Cia peb sim los tsim hloov qhov kev txiav txim cov lus Drools (mus zoo kab ntawv) rau ib tug (.drl) cov ntaub ntawv nyob rau hauv Drools.
Cov chav kawm ntawv uas tsis yog SpreadsheetCompiler yuav siv hloov input XLS thiab CSV ntawv rau ib tug (.drl) cov ntaub ntawv. Cov pob yuav tsum yog “org.drools.decisiontable.SpreadsheetCompiler”.Koj yuav tau siv cov compile () hom hoob kawm no yuav tau ua tus conversion. Cov piv txwv hauv qab no qhia tau hais tias cov processs.
Example program:-
ntshuam java.io.FileInputStream;
ntshuam java.io.FileNotFoundException;
ntshuam java.io.InputStream;
ntshuam org.drools.decisiontable.InputType;
ntshuam org.drools.decisiontable.SpreadsheetCompiler;
pej xeem hoob ExcelToDrlDemo {
pej xeem tsis muaj dabtsis loj zoo li qub(Txoj hlua args[]) {
// tsim ib cov kwj input
InputStream = null;
sim {
// cob rau excel mus rau tus kwj input
// pav ib txog kev hauv zos directory qhov twg koj excel cia
// koj nqa tau ib cov lus txiav txim (mus zoo ntawv) kev soj ntsuam
= yog tshiab FileInputStream(“D:/Workspace/TestProj/src/ExamplePolicyPricing.xls”);
} ntes (FileNotFoundException e) {
e.printStackTrace();
}
// tsim compiler hoob lom
SpreadsheetCompiler sc = tshiab SpreadsheetCompiler();
// compile lub excel rau Meskas lub (.drl) cov ntaub ntawv
Txoj hlua drl=sc.compile(yog, InputType.XLS);
// xyuas cov generated (.drl) cov ntaub ntawv
System.out.println(“Ua kom muaj DRL ntaub ntawv –: “);
System.out.println(drl);
}
}
