Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
环境：paoding 2.0.4 beta,lucene 2.9.1

public static void createIndex(String str) {
        IndexWriter writer;
        try {
            Directory directory = new SimpleFSDirectory(new 
File(index),new SimpleFSLockFactory());  
            writer = new IndexWriter(directory, analyzer, 
true,IndexWriter.MaxFieldLength.UNLIMITED);
            Document doc = new Document();
            Field field = new Field("content", str, 
Field.Store.YES,
                Field.Index.ANALYZED, 
Field.TermVector.WITH_POSITIONS_OFFSETS);
            doc.add(field);
            System.out.println(writer);
            writer.addDocument(doc);
            //writer.close();
            System.out.println("Indexed success!");
        } catch (CorruptIndexException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (LockObtainFailedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }
上述创建索引方法失败。报异常如下：
