Answer 1

xml文件没有改变,
报shell-servlet.xml文件不存在的错误,可是这个文件根本就是需要的.是不是我还少了什么包,或者有谁知道这个文件记录的什么内容,格式是怎么样的,请一并给出.
产生的新异常如下: <pre>org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from ServletContext resource [/WEB-INF/shell-servlet.xml]; nested exception is java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/shell-servlet.xml]
