在Hibernate Spring中添加TransactionManager

Question

添加事务管理器时出现错误。怎么了?：／很少有可能的答案是缺乏一些hibernate库。然而，似乎所有这些都存在。如何克服这一点?我还想添加一些测试数据到我的数据库。在哪个类中插入它比较好?谢谢你！

错误:

    org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception 
parsing XML document from ServletContext resource [/WEB-INF/dispatcher-servlet.xml]; nested
 exception is java.lang.NoClassDefFoundError: org/aopalliance/intercept/MethodInterceptor

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后得到next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

解决方案之一是将<aop:aspectj-autoproxy proxy-target-class="true"/>添加到dispatcher-servlet中。错误:

    org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'miniVLEController' defined in file 
[C:Users1DocumentsNetBeansProjectscom3014_mini_VLEbuildwebWEB-
INFclassesminiVLEcontrollerminiVLEController.class]: BeanPostProcessor before

org/aspectj/lang/annotation/Aspect

Answer 1

您需要添加一个opalliance.jar依赖项。如果你使用maven:

<dependency>
    <groupId>aopalliance</groupId>
    <artifactId>aopalliance</artifactId>
    <version>1.0</version>
</dependency>

Answer 2

问题升级后:

需要找到丢失的aspectjrt-1.x.x.jar以克服上次错误，然后克服org.aspectj.util.PartialOrder.PartialComparable错误，您需要获得aspectjtools-1.X.X.jar

在这里我找到了所有我需要的额外库http://www.jarfinder.com/index.php/java/info/org.aspectj.lang.NoAspectBoundException
