Wie Drools Decision Tabelle in mehreren Blättern der gleichen Excel-Datei zu importieren, mit Drools 6?

Question

Ich bin keine spezifische Art und Weise bekommen, es zu tun geifert mit 6. ich versucht hatte, es mit dem folgenden Beispielcode zu tun: `

private static KieBase readBase(String strFilePath) throws IOException, BiffException { 
     DecisionTableConfiguration dtconf = KnowledgeBuilderFactory.newDecisionTableConfiguration(); 
     dtconf.setInputType(DecisionTableInputType.XLS); 

     KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); 
     File xls = new File(strFilePath); 

     SpreadsheetCompiler compiler = new SpreadsheetCompiler(); 
     Workbook w; 
     String sheetName = ""; 
     FileInputStream in = null; 

     try { 

      w = Workbook.getWorkbook(xls); 
      for (Sheet sheet : w.getSheets()) { 

       sheetName = sheet.getName(); 
       in = new FileInputStream(xls); 

       System.out.println("The sheet name is : " + sheetName); 

       compileSheet(kbuilder, xls, compiler, sheetName, in); 


      } 


     } catch (DecisionTableParseException e) { 
      System.out.println("Failed to parse spreadsheet " + sheetName + " " 
        + e); 
     } 

     KieBase k = KnowledgeBaseFactory.newKnowledgeBase(); 
//  kContainer. 
     KnowledgeBase kb = KnowledgeBaseFactory.newKnowledgeBase(); 
     kb.addKnowledgePackages(kbuilder.getKnowledgePackages()); 

     return kb; 
    } 

    private static KnowledgeBuilder compileSheet(KnowledgeBuilder kbuilder, File xls, SpreadsheetCompiler compiler, String sheetName, FileInputStream in) { 
     try { 
      String compiled = compiler.compile(in, sheetName); 

      kbuilder.add(ResourceFactory.newReaderResource(new StringReader(compiled)), ResourceType.DRL); 
      System.out.println("***************************************drl**************************************"); 
      System.out.println(compiled); 

     } catch (DecisionTableParseException dtpe) { 
      if (dtpe.getMessage().equals("No RuleTable's were found in spreadsheet.")) { 
       System.out.println("No rule tables found in sheet {}" + sheetName); 
      } else { 
       throw dtpe; 
      } 
     } 
     return kbuilder; 
    }

Problem hier ist geifert 6 verwendet KIEBase Nicht KnowledgeBase, daher bekomme ich keinen geeigneten Weg kompilierte Blätter in KieBase zu laden. Gibt es einen anderen Weg, es in Drools 6 zu tun?

Answer 1

KieServices kieServices = KieServices.Factory.get(); 
KieFileSystem kfs = kieServices.newKieFileSystem(); 
FileInputStream fis = new FileInputStream("dir/some.drl"); 
kfs.write("src/main/resources/simple.drl", 
      kieServices.getResources().newInputStreamResource(fis)); 

KieBuilder kieBuilder = kieServices.newKieBuilder(kfs).buildAll(); 

Results results = kieBuilder.getResults(); 
if(results.hasMessages(Message.Level.ERROR)){ 
    System.out.println(results.getMessages()); 
    throw new IllegalStateException("### errors ###"); 
} 

KieContainer kieContainer = 
    kieServices.newKieContainer(kieServices.getRepository().getDefaultReleaseId()); 
KieBase kieBase = kieContainer.getKieBase(); 

Sie können dies auch mit dsl, dslr und xls-Dateien verwenden.
