Lucene使用IKAnalyzer分词时报错：”TokenStream contract violation: close() call missing” 解决办法是每次完成后必须调用关闭方法。
如果报错：java.lang.illegalstateexception: tokenstream contract violation: reset()/close() call missing,则要在tokenStream.incrementToken()，原因是lucene从4.6.0开始tokenstream使用方法更改的问题，在使用incrementtoken方法前必须调用reset方法，详见api http://lucene.apache.org/core/4_6_0/core/index.html 。
以下正确示例代码(第10行和22行调用reset()和close()方法)：
public Set<String> slicing(String text){ Set<String> result = new HashSet<>(); StringReader reader = null; TokenStream tokenStream = null; try { reader = new StringReader(text); tokenStream = analyzer.tokenStream("", reader); CharTermAttribute charTermAttribute = tokenStream.getAttribute(CharTermAttribute.class); OffsetAttribute offsetAttribute = tokenStream.addAttribute(OffsetAttribute.class); tokenStream.reset(); while (tokenStream.incrementToken()) { int startOffset = offsetAttribute.startOffset(); int endOffset = offsetAttribute.endOffset(); if((endOffset - startOffset) > 1){ String term = charTermAttribute.toString(); result.add(term); } } } catch (IOException e) { e.printStackTrace(); } finally{ IOs.close(tokenStream, reader); } return result; }
