Lucene高版本(5.5.4) IKAnalyzer2012_u6版本Jar包修改方式

Maven配置

清除IKAnalyzer2012_u6所依赖的Lucene4.7.2相关jar包

重新写IKAnalyzer的jar包下org.wltea.analyzer.lucene下的IKANalyzer.java和IKTokenizer.java

package org.wltea.analyzer.lucene;

import java.io.Reader;

import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.Tokenizer;

public final class IKAnalyzer extends Analyzer {

	private boolean useSmart;

	public boolean useSmart() {
		return useSmart;
	}

	public void setUseSmart(boolean useSmart) {
		this.useSmart = useSmart;
	}

	public IKAnalyzer() {
		this(false);
	}

	public IKAnalyzer(boolean useSmart) {
		super();
		this.useSmart = useSmart;
	}

	/*
	//Lucene4.7.2
	@Override
	protected TokenStreamComponents createComponents(String fieldName, final Reader in) {
		Tokenizer _IKTokenizer = new IKTokenizer(in, this.useSmart());
		return new TokenStreamComponents(_IKTokenizer);
	}
	*/
	/**
	 *支持 Lucene5.5.4
	 * @author lucheng
	 */
	@Override
	protected TokenStreamComponents createComponents(String fieldName) {
		Tokenizer _IKTokenizer = new IKTokenizer(this.useSmart());
		return new TokenStreamComponents(_IKTokenizer);
	}

}

package org.wltea.analyzer.lucene;

import java.io.IOException;

import org.apache.lucene.analysis.Tokenizer;

	}
	*/
	/**

	@Override

			termAtt.append(nextLexeme.getLexemeText());

			termAtt.setLength(nextLexeme.getLength());

			offsetAtt.setOffset(nextLexeme.getBeginPosition(), nextLexeme.getEndPosition());

			endPosition = nextLexeme.getEndPosition();

			typeAtt.setType(nextLexeme.getLexemeTypeString());

			return true;
		}
		return false;
	}

	@Override
	public void reset() throws IOException {
		super.reset();
		_IKImplement.reset(input);
	}
	@Override
	public final void end() {
		int finalOffset = correctOffset(this.endPosition);

	}
}

从Maven本地中仓库中将com.janeluo.ikanalyzer.2012_u6.ikanalyzer-2012_u6.jar复制出来用WinRAR打开，找到org.wltea.analyzer.lucene下的IKANalyzer.class和IKTokenizer.class

删除原有的IKANalyzer.class和IKTokenizer.class。

找到我们创建的org.wltea.analyzer.lucene包下修改后的IKANalyzer.java和IKTokenizer.java所编译后生成的class文件，将这两个class文件粘粘进去。
