找不到类，Morphia，Spring的编解码器

Question

向运行Spring BOOT的tomcat发布JSON。

通过Morphia映射请求更新Mongo

获取错误：“状态”：500，“错误”：“内部服务器错误”，“异常”：“org.bson.codecs.configuration.CodecConfigurationException”，“message”：“无法找到编解码器class se.preffo.model.ProfileAccess。

不知何故，它不知道如何创建Object ProfileAccess

ProfileAccess类：

ProfileController可

// ---------------------- UPDATE LIST OF PROFILES
        @RequestMapping(value="/profiles/batch", method=RequestMethod.POST)
        public void updateProfile(@RequestBody List<Profile> profiles) {

            logger.debug(profiles.get(0).toString());

            profileService.updateProfiles(profiles);
        }

ProfileService

public void updateProfiles(List<Profile> profiles) {

        datastore = MongoDbHelper.INSTANCE.getDatastore();

        for (Profile profile : profiles) {

            logger.debug(profile.toString());

            datastore.save(profile);
        }

    }

MongoDbHelper

   private MongoDbHelper() {

            MongoClient mongoClient = new MongoClient(new MongoClientURI("uritomongodb"));
            Morphia morphia = new Morphia(); 
            this.datastore = morphia.createDatastore(mongoClient, DATABASE_NAME);


        }

        public Datastore getDatastore() {
            return this.datastore;
        }
