在Hibernate Spring中添加TransactionManager

[英]Adding TransactionManager in Hibernate Spring

Getting error when adding Transaction-Manager. 添加Transaction-Manager时出错。 What's wrong? 怎么了? :/ Few possible answers reffer to lack of some hibernate libraries. :/几乎没有可能的答案是因为缺少一些休眠库。 However It seems that all of them do persist. 但是,似乎所有这些方法都确实存在。 How to overcome this? 如何克服呢? Also I want to add some test data to my database. 我也想向我的数据库添加一些测试数据。 In what class is it better to insert it? 插入哪个类中更好? Thank you. 谢谢。

ERROR: 错误:

DAO: 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);        
}....

Service: 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);
    }...

Controller: 控制器:

@Controller
public class miniVLEController {

    @Autowired
    StudentService studentService;

After adding the aopalliance-1.0.jar getting next ERROR: 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

One of the solutions was to add <aop:aspectj-autoproxy proxy-target-class="true"/> into the dispatcher-servlet. 解决方案之一是将<aop:aspectj-autoproxy proxy-target-class="true"/>到调度程序servlet中。 next Error: 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-
INF\classes\miniVLE\controller\miniVLEController.class]: BeanPostProcessor before 
instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError:

You need to add aopalliance.jar dependency. 您需要添加aopalliance.jar依赖项。 If you use maven: 如果使用maven:

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

Following the problem escalation: 问题升级之后:

Needed to find aspectjrt-1.xxjar that was missing to overcome last error and then to overcome org.aspectj.util.PartialOrder.PartialComparable error you need to get aspectjtools-1.XXjar 需要找到缺少的Aspectjrt aspectjrt-1.xxjar以克服上一个错误,然后要克服org.aspectj.util.PartialOrder.PartialComparable错误,您需要获取aspectjtools-1.XXjar

here I found all extra libraries i needed http://www.jarfinder.com/index.php/java/info/org.aspectj.lang.NoAspectBoundException 在这里,我找到了我需要的所有其他库http://www.jarfinder.com/index.php/java/info/org.aspectj.lang.NoAspectBoundException
