  2.   

    回去检查下注解扫描有没有开在userBizImpl这个类所在的包
      

  3.   

    我在springmvc-servlet里写了
    <!-- 对web包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 -->
         <context:component-scan base-package="*"/>
    应该有扫到吧

    我在springmvc-servlet里写了
    <!-- 对web包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 -->
         <context:component-scan base-package="*"/>
    应该有扫到吧<context:annotation-config />加上这句
      

  5.   

    UserBizImpl用bean的配置文件配置吧
      

  6.   

    @Controller
    public class UserController {@Resource(name="userBiz")
    private UserBiz userBiz;
    你的这个userBiz  这个@Resource有问题，spring你既然配置了自动注入bean，为啥不用@Autowired
