为Elasticsearch构建自定义标记器

为此，我正在构建自定义标记器：doc_values字段与已分析字段的性能

这个API似乎都没有记录（？），因此我不打算使用其他插件/令牌生成器的代码示例，但是当我重新部署弹性代码并部署了令牌生成器时，在日志中不断出现此错误：

我的令牌生成器是为v2.3.4构建的，令牌生成器工厂如下所示：

public class UrlTokenizerFactory extends AbstractTokenizerFactory {

    @Inject
    public UrlTokenizerFactory(Index index, IndexSettingsService indexSettings, @Assisted String name, @Assisted Settings settings){
        super(index, indexSettings.getSettings(), name, settings);
    }

    @Override
    public Tokenizer create() {
        return new UrlTokenizer();
    }
}

我真的不知道我在做什么错。我部署不正确了吗？它似乎正在根据日志使用我的课程...

我仅将其部署到我的es节点之一（4节点集群）。该/_cat/plugins?v端点给出了这样的：

name         component          version type url 
Samuel Silke urltokenizer       2.3.4.0 j        

由于此过程的文档很少或没有文档，因此，通过复制其他人在插件中创建的构造，我已经走了很远。

我看到的错误没有任何意义。我的TokenizerFactory看起来像其他所有人都在使用此版本的Elastic。我在做错什么，或者可能做错了我应该做的这项工作？
