Solr中使用自定义查询分析器操纵查询(Manipulating query using Custo

我试图创造一个我利用OpenNLP库，以及一个CustomQueryParser。

我的目标是，如果我有一个查询“有多少缺陷的轮辋，在中国ABC轮胎引起的故障”

我想最终的查询是这样的“缺陷轮辋轮胎故障中国”，然后会去分析仪进行进一步的处理。

这是我QueryParserPlugin代码 -

package com.mycompany.lucene.search;
import org.apache.solr.common.params.SolrParams;
import org.apache.solr.request.SolrQueryRequest;
import org.apache.solr.search.QParser;
import org.apache.solr.search.QParserPlugin;
import com.mycompany.lucene.search.QueryParser;

public class QueryParserPlugin extends QParserPlugin {
@Override
  public QParser createParser(String qstr, SolrParams localParams, 
SolrParams params, SolrQueryRequest req) {
    return new QueryParser(qstr, localParams, params, req, "body_txt_str");
  }
}

而对于我的QueryParser代码 -

package com.mycompany.lucene.search;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.TokenStream;
import org.apache.lucene.analysis.tokenattributes.CharTermAttribute;
import org.apache.lucene.index.Term;
import org.apache.lucene.search.PhraseQuery;
import org.apache.lucene.search.Query;
import org.apache.lucene.search.TermQuery;
import org.apache.solr.common.params.SolrParams;
import org.apache.solr.request.SolrQueryRequest;
import org.apache.solr.search.QParser;
import org.apache.solr.search.SyntaxError;
import opennlp.tools.postag.POSModel;
import opennlp.tools.postag.POSTaggerME;
import opennlp.tools.tokenize.Tokenizer;
import opennlp.tools.tokenize.TokenizerME;
import opennlp.tools.tokenize.TokenizerModel;

public class QueryParser extends QParser {

  private String fieldName;

public QueryParser(String qstr, SolrParams localParams, SolrParams params, 
SolrQueryRequest req,
      String defaultFieldName) {

    super(qstr, localParams, params, req);

    fieldName = localParams.get("field");
    if (fieldName == null) {
      fieldName = params.get("df");
    }
  }
@Override
  public Query parse() throws SyntaxError {
    Analyzer analyzer = req.getSchema().getQueryAnalyzer(); 
    InputStream tokenModelIn = null;
    InputStream posModelIn = null;
    try {
        tokenModelIn = new FileInputStream("/Files/en-token.bin");
     } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    TokenizerModel tokenModel = null;
    try {
        tokenModel = new TokenizerModel(tokenModelIn);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    Tokenizer tokenizer = new TokenizerME(tokenModel);
    String tokens[] = tokenizer.tokenize(qstr);

    try {
        posModelIn = new FileInputStream("/Files/en-pos-maxent.bin");
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
         e.printStackTrace();
    }
      // loading the parts-of-speech model from stream
    POSModel posModel = null;
    try {
         posModel = new POSModel(posModelIn);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    // initializing the parts-of-speech tagger with model 
    POSTaggerME posTagger = new POSTaggerME(posModel);
    // Tagger tagging the tokens
    String tags[] = posTagger.tag(tokens);
    String final_query = "";
    for(int i=0;i<tokens.length;i++){
        if (tags[i]=="JJ" || tags[i]=="NNS" || tags[i]=="NN") {
            final_query = final_query + " " +tokens[i];
        }
    }
    TermQuery tq= new TermQuery(new Term(fieldName,final_query));  
    return tq; 
    }
}

然后我出口这是一个罐子，加入这些罐子我solrconfig.xml中 -

<lib dir="${solr.install.dir:../../../..}/contrib/customparser/lib" 
 regex=".*\.JAR" />
<lib dir="${solr.install.dir:../../../..}/contrib/analysis-extras/lib" 
 regex="opennlp-.*\.jar" />

但是，提示以下错误：

致：

这是我第一次创建CustomQueryParser，能否请你帮我出。

谢谢
