转换为 JSON：java.lang.NoClassDefFoundError：com/fasterxml/jackson/core/filter/TokenFilter

Question

坦率地说，我对 Elasticsearch (ES) 有问题，我想不通。我是 ES 新手，按照this 站点的教程，运行项目时出现以下错误：

2016-12-31 00:23:38.877 ERROR 6120 --- [pool-2-thread-1] o.s.s.s.TaskUtils$LoggingErrorHandler    : Unexpected error occurred in scheduled task.

java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/filter/TokenFilter 在 org.elasticsearch.common.xcontent.json.JsonXContent.createGenerator(JsonXContent.java:73) 在 org.elasticsearch.common.xcontent.XContentBuilder.(XContentBuilder.java:112) 在 org.elasticsearch.common.xcontent.XContentBuilder.(XContentBuilder.java:102)

py pom.xml 是：

我的工人阶级是：

    Node node  = nodeBuilder().settings(Settings.builder().put("path.home","/data"))
                              .clusterName("elasticsearch").node();
    Client client = node.client();
    //SearchQuery searchQuery ;
    private static final String INDEX_NAME = "Proven_news";
    private static final String TYPE = "news";


    public void createIndex(ProvenNews pNews)
    {
        System.out.println(pNews.getId());
        client.prepareIndex(INDEX_NAME, TYPE, pNews.getId().toString()).setSource(putJsonDocument(pNews)).execute().actionGet();
        System.out.println(pNews.getUrl() + " - saved in ElasticSearch");
    }


    public static Map<String, Object> putJsonDocument(ProvenNews pNews)
    {
        Map<String, Object> jsonDocument = new HashMap<String, Object>();
        jsonDocument.put("entity", pNews.getEntity());
        jsonDocument.put("newsDate", pNews.getNewsDate());
        jsonDocument.put("newsText", pNews.getNewsText());
        jsonDocument.put("title", pNews.getTitle());
        jsonDocument.put("url", pNews.getUrl());
        return jsonDocument;
}

加载jackson库的pom在哪里......我认为部署时jackson-core jar没有添加到你的lib文件夹中......请列出jackson库的maven条目。
