Maven 2 斯普林·马歇尔+；contextPath+；嵌入maven抛出的tomcat

我正在使用spring的Jaxb2Marshaller（没有web服务）来解组一些xml。xml代码是通过maven jaxb插件编写的代码gen，我通过以下方式在spring中实例化了Jaxb2Marshaller：

<bean id="unmarshaller" class="...Jaxb2Marshaller" p:contextPath="my.package.path" />  

第一个解组器创建得很好，第二个抛出org.springframework.oxm.jaxb.JaxbSystemException，因为它找不到ObjectFactory（它是由maven jaxb插件生成的，我已经验证了它实际上存在于jar中的正确包中）

实际上，我有两个解组器（尽管我尝试了使用一个解组器和使用冒号分隔的包路径的contextPath，结果相同）

我不认为这通常是spring或我的配置的问题，因为如果我部署到一个完整的tomcat容器中，它就可以正常工作。我注意到maven将tomcat放在我的project/target/tomcat文件夹中，并且存在一些差异，比如没有lib目录。实际上，我不知道嵌入式tomcat和常规安装之间有什么区别

有人能解释一下吗：
1） 嵌入式tomcat与常规安装的具体区别
2） 如果存在已知的限制
3） 如果可以将其配置为在此情况下正常工作

对于其他遇到此问题的人，我最终通过使用classesToBeBound属性而不是contextPath解决了这个问题。我最初避免classesToBeBound的原因是我认为我必须在classesToBeBound列表中指定模型中的每个类，但事实并非如此。您只需指定具有@XmlRootElement注释的类
