package com.puppet.util;
import org.apache.lucene.index.IndexWriter; import org.apache.lucene.util.Version; import org.apache.lucene.analysis.standard.StandardAnalyzer; public class IndexProcess { private String INDEX_STORE_PATH=""; public void createIndex(String inputDir){ try { IndexWriter writer= new IndexWriter(INDEX_STORE_PATH,new StandardAnalyzer(Version.LUCENE_CURRENT),true,IndexWriter.MAX_TERM_LENGTH); } catch (Exception e) { e.printStackTrace(); } } } 上面红色行一直报错,说没有这个构造函数。 error:The constructor IndexWriter(String,StandardAnalyzer,boolea,int) id undefined 换成这样也不行。 IndexWriter writer= new IndexWriter(INDEX_STORE_PATH,new StandardAnalyzer(),true); 我用的包是3.0的 我刚学,麻烦各位大大帮忙解决下。 |

IndexWriter(Directory d, Analyzer a, boolean create, IndexWriter.MaxFieldLength mfl)
Constructs an IndexWriter for the index in d. http://lucene.apache.org/java/3_0_2/api/all/org/apache/lucene/index/IndexWriter.html#IndexWriter(org.apache.lucene.store.Directory, org.apache.lucene.analysis.Analyzer, boolean, org.apache.lucene.index.IndexWriter.MaxFieldLength) 3的构造函数和2不同,目录参数不能是String,必须是Directory类型的 最后一个参数MaxFieldLength不是int的,是自定义的类型 |

Directory 参数一般这样取得
Directory dir = FSDirectory.open("d:\index\"); |
