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

Question

坦率地说，Elasticsearch（ES）存在问题，我无法弄清楚。我是新来的ES，并按照从this网站上的教程，在运行该项目下面的错误是发生：

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 /杰克逊/核心/过滤/ TokenFilter 在org.elasticsearch.common.xcontent.json.JsonXContent.createGenerator（JsonXContent.java:73） at org.elasticsearch.common.xcontent.XContentBuilder。（XContentBuilder.java:112） at org.elasticsearch.common.xcontent.XContentBuilder 。（XContentBuilder.java:102）

py pom.xml是：

和我的工人阶级是：

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; 
}

其中是pom加载杰克逊库....我认为杰克逊核心jar没有添加到您的lib文件夹当您部署....请列出杰克逊库的maven条目。
