我正在编写一个语义 Web 应用程序，但 Jena 遇到了一些问题。我想执行一个参数化查询并且没有结果。
以下代码显示了我的查询：
public ArrayList getPieceByContrName(String n){
Property pr= infModel.getProperty(namespace+"NomPiecePreparer");
ArrayList ef=new ArrayList();
Query query = null;
QueryExecution qe = null;
String sql= "PREFIX supply: <http://www.semanticweb.org/ontologies/2012//Ontology1334514742253.owl#>"+
" SELECT ?y " +
" WHERE {" +
" ?x supply:NomSControle \""+n+"\"." +
"?x supply:controle ?y"+"." +
" }";
com.hp.hpl.jena.query.ResultSet results = null;
try{
query=QueryFactory.create(sql);
qe= QueryExecutionFactory.create(query,infModel);
results = qe.execSelect();
System.out.println("rrrrr");
} catch (Exception e) {
e.printStackTrace();
}
while(results.hasNext()){
System.out.println("hhhhh");
PiecePrepare pp = new PiecePrepare();
QuerySolution soln = results.next() ;
Resource r= soln.get("y").asResource();
System.out.println(r.getProperty(pr).getString());
}
qe.close();
}
这是我本体的一部分：
