Question

请问lucene错误提示：The constructor IndexWriter(String, StandardAnalyzer) is undefined问题怎么解决

Analyzer luceneAnalyzer = new StandardAnalyzer(Version.LUCENE_30);
IndexWriter FSWriter = new IndexWriter(indexPath,luceneAnalyzer,true);
在这里出现错误。。。我用的是lucene-3.0.2

已经引入了相关的包
import java.io.File;
import java.io.FileReader;
import java.io.Reader;
import java.util.Date;
import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.standard.StandardAnalyzer;
import org.apache.lucene.document.Document;
import org.apache.lucene.document.Field;
import org.apache.lucene.index.IndexWriter;
import java.io.IOException;
import org.apache.lucene.store.Directory;
import org.apache.lucene.store.RAMDirectory;
为什么还会出现这种状态呢，lucene-core-3.0.2.jar和lucene-demos-3.0.2.jar也已经导入到build path里了

Answer 1

IndexWriter FSWriter = new IndexWriter(indexPath,luceneAnalyzer,true);这里的构造函数好像错了。

Answer 2

lucene-3.0.2中 IndexWriter中间必须有MAX_FIELD_LENGTH这个参数

Answer 3

函数的IndexWriter(字符串,StandardAnalyzer)是未定义的

Answer 4

没有这么个构造器

你查下api吧，或者直接看源代码
