eclipse 中web项目部署到tomcat上的问题，tomcat下没有.class文件

最近学习了下springmvc，写了个HelloWorld工程，可总是部署到tomcat上时出现错误，求大神指点一下。说是找不到HelloController，可src中明明有，然后去tomcat目录下看，才知道其他的东西都有，唯独没有HelloController.class文件，求大神指点哪里错了，还是少了什么配置，错误如下：
严重: Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping#0' defined in ServletContext resource [/WEB-INF/hello-servlet.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.test.controller.HelloController] for bean with name '/hello' defined in ServletContext resource [/WEB-INF/hello-servlet.xml]; nested exception is java.lang.ClassNotFoundException: com.test.controller.HelloController

.HelloController] for bean with name '/hello' defined in ServletContext resource [/WEB-INF/hello-servlet.xml];
----------------------这个应该是配置哪里出错了，可以查看一下配置文件
