无法使用spring3 restful生成json数据

大家好，我是spring restful服务的新手。我正在尝试将我的一个方法公开为restful，并从这个url获取xml数据（localhost:7001/SpringRestService/restful/showAllGrants/All/All/All.xml） 但当我键入（localhost:7001/SpringRestService/restful/showAllGrants/ITSMAXK/ALL/ALL.json）以获取json数据时，我得到的错误如下

哪个Spring Web MVC版本？在我看来，您的POM中有一个旧版本的Jackson。2.0.6对我来说很好。您确定使用的是上下文文件所指的Spring3.0吗？
