添加事务管理器时出错。怎么了？:/ 很少有可能的答案是缺少一些休眠库。但是，似乎所有这些都确实存在。如何克服这一点？另外我想在我的数据库中添加一些测试数据。在哪个类中插入它更好？谢谢你。
错误：

道：
@Repository
public class MiniVLEDAOImplementation implements MiniVLEDAO{
// Used for communicating with the database
@Autowired
private SessionFactory sessionFactory;
@Override
public void addStudentToDB(Student student) {
sessionFactory.getCurrentSession().saveOrUpdate(student);
}....
服务：
@Service
@Transactional(propagation = Propagation.SUPPORTS, readOnly = true)
public class StudentService implements IStudentService{
@Autowired
MiniVLEDAOImplementation dao;
public StudentService() {
System.out.println("*** StudentService instantiated");
}
@Override
public Student getStudent(String urn){
Student s = dao.getStudentFromDB(urn);
return s;
}
@Override
@Transactional(propagation = Propagation.REQUIRED, readOnly = false)
public void addStudent(Student student) {
dao.addStudentToDB(student);
}...
控制器：
@Controller
public class miniVLEController {
@Autowired
StudentService studentService;
添加 aopalliance-1.0.jar 后出现下一个 错误：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'miniVLEController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: miniVLE.service.StudentService miniVLE.controller.miniVLEController.studentService; nested exception is java.lang.IllegalArgumentException: Can not set miniVLE.service.StudentService field miniVLE.controller.miniVLEController.studentService to sun.proxy.$Proxy536
解决方案之一是添加<aop:aspectj-autoproxy proxy-target-class="true"/>到 dispatcher-servlet 中。下一个错误：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'miniVLEController' defined in file
[C:\Users\1\Documents\NetBeansProjects\com3014_mini_VLE\build\web\WEB-
