Maven 从RESTEasy方法调用mongo jackson映射器时出错

我已经在这上面呆了几天了。我有一个用maven构建的Javaservlet，它将被部署到Jetty（一个旧版本）。它是Jetty上的一个RESTful web服务，由RESTEasy和Jackson以及Jackson Mongo Mapper构建，用于将我连接到MongoDB

我可以在maven/jetty上运行应用程序（使用mvnjetty:run），对于不使用jacksonmongo映射器/Jackson位的查询，它会像预期的那样返回JSON。然而，当我发送一个触发Jackson和mapper的请求时，我首先遇到以下错误：

java.lang.NoClassDefFoundError: org/codehaus/jackson/map/deser/std/StdDeserializer

java.lang.NoClassDefFoundError: Could not initialize class net.vz.mongodb.jackson.JacksonDBCollection

当我第二次提交（以及所有后续请求）时，会出现以下错误：

java.lang.NoClassDefFoundError: org/codehaus/jackson/map/deser/std/StdDeserializer

java.lang.NoClassDefFoundError: Could not initialize class net.vz.mongodb.jackson.JacksonDBCollection

据我所知，我已经正确地设置了所有依赖项，尽管我将在问题的末尾包括我的web.xml和pom.xml。如果它不是一个依赖项，我就会想到，我的bean（BillItem.class）的传递方式可能存在一些问题。我对Java比较陌生，所以这很容易成为一个愚蠢的错误，而不是与我试图实现的特定堆栈相关的东西……有什么想法吗

下面的最后一行是抛出错误的违规调用：

        Mongo mongo = new Mongo(MONGO_PATH, MONGO_PORT);
        DB db = mongo.getDB(MONGO_APPDB);
        DBCollection collection = db.getCollection(MONGO_BILL_COL);
        JacksonDBCollection<BillItem, String> coll = JacksonDBCollection.wrap(collection, BillItem.class, String.class);

Mongo-Mongo=新的Mongo（Mongo\u路径，Mongo\u端口）；
DB DB=mongo.getDB（mongo_APPDB）；
DBCollection=db.getCollection（MONGO\u BILL\u COL）；
JacksonDBCollection coll=JacksonDBCollection.wrap（collection，BillItem.class，String.class）；

这是一种严重的愚蠢行为。在清理pom文件时，我不小心删除了3个jackson依赖项
