[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。

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-

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
