Cause of the exception:
This is because package conflicts occur when the spring framework and Hibernate framework are integrated. This bug is generated when myeclipse6.0 is used.

Jar files are: ASM. Jar conflicts with the asm-2.2.3.jar.

Solution: the video says to delete the asm-2.2.3.jar can run normally!
However, after I delete my machine, I still report the following error: org. springframework. Beans. Factory. beancreationexception: Error creating.

Bean with name 'datasource 'defined in servletcontext resource [/WEB-INF/applicationcontext. xml]: instantiation of bean

Failed; Nested exception is Java. Lang. noclassdeffounderror: ORG/Apache/commons/pool/impl/genericobjectpool

Later, I went to my lib directory and deleted many. Jar files with similar names (five or six. Jar files can be deleted), but I still reported the error, which is exciting!

Next, I went to watch the video and looked for clues. I suddenly found that myeclipse6.1 was used. hibernate only supported 3.1, while myeclipse6.5 was used in the video.

Hibernate3.2, So I downloaded myeclipse6.5 online. After the installation, I created a new project and copied all the files of the previous project (because the. Jar files are different

The previous project cannot be used directly.) after the project is deployed, it is indeed a full range of features in the higher version, and the errors reported are more targeted!

Changed:

<Value> COM/oristand/bean/user. HBM. xml </value>

Re-deployment and run: the following error occurs again, which is even more exciting:
Org. springframework. Beans. Factory. beancreationexception: Error creating bean with name 'sessionfactory 'defined in

Servletcontext resource [/WEB-INF/applicationcontext. xml]: Invocation of init method failed; Nested exception is

At this time, delete the corresponding asm-2.2.3.jar, re-deploy and run,

Success !!!!!!!!!!!!!!!!!!!!!!
