NoClassDefFoundError:com/fasterxml/jackson/databind/ObjectMapper with Red5

Question

我有一个Red5应用程序.由于Red5基于Tomcat,Tomcat大师可以提供帮助.

我的应用程序中有一个类,它使用Spring Social和Spring Social Facebook 1.1.0M3来初始化东西,以便准备一些实时的购买统计数据.

我有一个bean配置,用参数初始化该类.当我启动我的Red5并尝试创建我的bean时,我收到以下错误:

Error creating bean with name 'xpoFacebookPurchaseHandler' defined in ServletContext resource [/WEB-INF/red5-web.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/ObjectMapper

如何配置bean是无关紧要的,所以我没有在这里粘贴它.

所以我得到NoClassDefFoundError的com/fasterxml/jackson/databind/ObjectMapper

现在我正在使用它maven,每当我添加一个包时,它确保它添加了所有的依赖项,什么不是.

我收录了Jackson Databind v.2.2.2.

如果我执行

strings jackson-databind-2.2.2.jar | grep -i ObjectMapper.class$com/fasterxml/jackson/databind/ObjectMapper.class

我确实看到该类存在,并且该库位于我的项目的lib目录中.所以我无法弄清楚为什么当我执行我的项目时我仍然会得到NoClassDefFoundError.
