解决方案
解决方案二：
packagecom.mvc.controller;importjava.util.List;importjavax.servlet.http.HttpServletRequest;importjavax.servlet.http.HttpServletResponse;importorg.springframework.beans.factory.annotation.Autowired;importorg.springframework.stereotype.Controller;importorg.springframework.ui.ModelMap;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.bind.annotation.RequestParam;importcom.mvc.entity.Student;importcom.mvc.service.StudentService;importcom.sun.org.apache.commons.logging.Log;importcom.sun.org.apache.commons.logging.LogFactory;@Controller@RequestMapping("/student.do")publicclassStudentController{protectedfinaltransientLoglog=LogFactory.getLog("StudentController.class");@AutowiredpublicStudentServicestudentService;publicStudentController(){}publicStudentServicegetStudentService(){returnstudentService;}publicvoidsetStudentService(StudentServicestudentService){this.studentService=studentService;}@RequestMappingpublicStringload(ModelMapmodelMap){List<Student>list=studentService.findAll();modelMap.put("list",list);return"student";}@RequestMapping(params="method=add")publicStringadd(HttpServletRequestrequest,ModelMapmodelMap)throwsException{return"student_add";}@RequestMapping(params="method=save")publicStringsave(HttpServletRequestrequest,ModelMapmodelMap){Studentst=newStudent();Stringname=request.getParameter("name");Stringpsw=request.getParameter("psw");st.setName(name);st.setPsw(psw);try{studentService.save(st);modelMap.put("addstate","添加成功");}catch(Exceptione){e.printStackTrace();log.error(e.getMessage());modelMap.put("addstate","添加失败");}return"student_add";}@RequestMapping(params="method=del")publicvoiddel(@RequestParam("id")Stringid,HttpServletResponseresponse){try{Studentst=newStudent();st.setId(Integer.valueOf(id));studentService.delete(st);response.getWriter().print("{"del":"true"}");}catch(Exceptione){log.error(e.getMessage());e.printStackTrace();}}}这是controller
解决方案三：

spring配置贴出来看看，你的sessionFactory的class是不是：org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean？

解决方案十二：
我就讲方法好了：错误注释“Errorcreatingbeanwithname'studentController':Injectionofautowireddependenciesfailed;”一个叫studentController的注入错误。下面一句：Couldnotautowirefield:publiccom.mvc.service.StudentServicecom.mvc.controller.StudentController.studentService;这句不能自动装配下面这个包的studentService下句Nomatchingbeanoftype[com.mvc.service.StudentService]foundfordependency没有找到相匹配的类型。仔细看看是不是注释，配置哪里弄错了，自己弄出来不会忘。

你首先要仔仔细细的看清楚你报的错误，就像楼上说的，为什么注入bean的时候会报找不到匹配类型的错误？怀着问题来看我发给你的帖子
解决方案十四：
注解@Service("studentService")和@Transactional应该标在StudentService的实现类类名上
解决方案十五：
异常表明属性没有注入进去注解@Service("studentService")应该写到StudentService的实现类类名上比如@Service@TransactionalpublicclassUserServiceImplextendsDaoSupportImpl<User>implementsUserService{

我是写在实现类上的

我还是刚接触不懂springmvchibernate
解决方案：
你都没有StudentService的接口，怎么面向接口编程，怎么注解啊。
解决方案：
@Controller@RequestMapping("/student.do")publicclassStudentController{protectedfinaltransientLoglog=LogFactory.getLog("StudentController.class");@AutowiredpublicStudentServicestudentService;你自己注意StudentService要求是接口，你现在放的是实现类，那还要什么注入，你都可以自己new了，当然你不能这么做。

那你的意思是我把StudentService作为接口？
解决方案：
我的意思是你在controller中需要引用的是一个接口，而你却直接引用了实现了，这是不对的。他们的关系应该是这样的：StudentController内部引用一个StudentService(接口),你自己需要写一个StudentService的实现，例如：StudentServiceImplimplementsStudentService。而你现在controller引用了实例。StudentController引用StudentService(接口)<--StudentServiceImpl(实现)，注入的是StudentServiceImpl。
