Drools 决策表转drl

在drools5.0中,org.drools.decisiontable.SpreadsheetCompiler这个类可以把xls文件流转化为drl的String对象,通过FileWriter来写成drl文件,相关的转换代码是:
public String drlString(String file,String toDir) throws Exception{
SpreadsheetCompiler sc = new SpreadsheetCompiler();
File f = new File(file);
String fileName = f.getName();
String name = fileName.substring(0,fileName.lastIndexOf("."));
FileInputStream xlsStream = new FileInputStream(f);
String drlFileTmp = sc.compile(xlsStream, InputType.XLS);
drlFileTmp.replaceAll(".xls", ".drl");
File drlFile = new File(toDir + "/" + name + ".drl");
FileWriter writer = new FileWriter(drlFile);
writer.write(drlFileTmp);
writer.close();
return drlFileTmp;
}
