弹性搜索 - 在java中创建节点/索引时出错

时间：2012-06-07 12:24:01

标签： java elasticsearch

我正在努力获得概念证明Java代码的工作原理。我要做的第一件事是在我的HD上索引一些txt文档。但是，在尝试创建节点时遇到异常之前，我甚至没有那么远。

以下代码都会产生以下异常：

代码 

Node node = nodeBuilder().node();
Client client = node.client();

我的主要问题是：

我可以获得似乎缺少的BoundaryScanner类吗？我将在异常下面提供我的maven pom.xml 。 lucene-fast-vector-highlighter包似乎是最新版本3.0.3。

任何帮助都非常感激。

在同一个项目中混合不同版本的Lucene组件并不是一个好主意。你应该使用3.6.0的一切。最近版本中有一些更改，因此您需要替换/删除一些工件。例如，Snowball分析仪现在使用lucene分析仪，所以你不需要lucene-snowball神器，lucene-fast-vector-highlighter现在是lucene-highlighter：

      <dependency>
        <groupId>org.apache.lucene</groupId>
        <artifactId>lucene-core</artifactId>
        <version>3.6.0</version>
      </dependency>           

      <dependency>                  
        <groupId>org.apache.lucene</groupId>
        <artifactId>lucene-analyzers</artifactId>   
        <version>3.6.0</version>                            
      </dependency>                                               

      <dependency>
        <groupId>org.apache.lucene</groupId>
        <artifactId>lucene-highlighter</artifactId>
        <version>3.6.0</version>
      </dependency>

      <dependency>
        <groupId>org.apache.lucene</groupId>
        <artifactId>lucene-queries</artifactId>
        <version>3.6.0</version>
      </dependency>
