使用EJB3.0 + jersey restful API + lucene 6.1
分析仪是Jcseg中文分析仪。
@Stateless
public class GoodsSearchBiz implements Serializable {
@Override
public List<String> test(){
Analyzer analyzer = new JcsegAnalyzer5X(JcsegTaskConfig.SEARCH_MODE);
JcsegAnalyzer5X jcseg = (JcsegAnalyzer5X) analyzer;
JcsegTaskConfig config = jcseg.getTaskConfig();
config.setAppendCJKSyn(true);
config.setAppendCJKPinyin(true);
TokenStream stream = null;
List<String> strList = new ArrayList<>();
try {
FSDirectory directory = FSDirectory.open(Paths.get(ResourcesUtils.loadGoodsMarketIndexDir()));
IndexWriterConfig iwConfig = new IndexWriterConfig(analyzer);
iwConfig.setOpenMode(IndexWriterConfig.OpenMode.CREATE_OR_APPEND);
IndexWriter iwriter = new IndexWriter(directory, iwConfig);
iwriter.deleteAll();
String words = "中华人民共和国";
Document doc = new Document();
doc.add(new TextField(SearchGoodsVO.FIELD_NAME, words, Field.Store.YES));
iwriter.addDocument(doc);
iwriter.commit();
iwriter.close();
stream = analyzer.tokenStream(SearchGoodsVO.FIELD_NAME, words);
stream.reset();
CharTermAttribute offsetAtt = stream.addAttribute(CharTermAttribute.class);
while (stream.incrementToken()) {
strList.add(offsetAtt.toString());
}
stream.end();
if (stream != null) stream.close();
} catch (Exception e) {
e.printStackTrace();
}
System.out.println(strList);
return strList;
}
在Main中运行它会产生不同的结果
public static void main(String[] args) {
GoodsSearchBiz goodsSearchBiz = new GoodsSearchBiz();
goodsSearchBiz.test();
}
}
/*The Api*/
@Path("/search")
@Produces(RestMediaType.JSON_HEADER)
@Consumes(RestMediaType.JSON_HEADER)
public class GoodsSearchApi {
@EJB
GoodsSearchBiz searchBiz;
@GET
@Path("/test")
public List<String> test() {
return searchBiz.test();
}
}
结果：
来自Main的：
[中华, 中华人民共和国, 华人, 人民, 人民共和国, 共和, 共和国]
Process finished with exit code 0
来自API：
09:31:05,433 INFO [stdout] (default task-1) [中, 华, 人, 民, 共, 和, 国]
为什么相同的代码会给出不同的结果？
