如何解決FileNotFoundException

java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/springmvc-servlet.xml]

    at org.springframework.web.context.support.ServletContextResource.getInputStream(ServletContextResource.java:141)

    at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:330)

    at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:304)

在運作時找不到classpath，或者classpath指定的bean有誤，類名和路徑是不是和寫的一樣
