spring MVC helloworld应用程序显示CannotLoadBeanClassException
spring MVC helloworld应用程序显示CannotLoadBeanClassException
提问于 2015-03-08 16:43:21
我是spring MVC.I的新手，我正在学习下面的链接中的教程：Spring Hello World
在tomcat服务器上运行应用程序时，显示以下异常，我猜可能与控制器类文件路径有关，但无法解决：

您在SpringMVCTutorial-servlet.xml中放置了错误的类路径。使用以下路径
<bean name="/helloworld.htm"
class="com.springmvctutorial.web.controller.HelloWorldController"/>Stack Overflow用户

看起来java.com.springmvctutorial.web.controller.HelloWorldController对应的类文件不在类路径下。
所以这里有两件事要检查：
1)是否创建HelloWorldController的类文件。
2)如果是，则包含i.e. java.com.springmvctutorial.web.controller.HelloWorldController的文件夹应该在类路径下
理想情况下，包名称应以com.springmvctutorial开头。不是用java.com..按照java约定
