在Maven项目中配置Hibernate 4.2.1

Question

I'm configuring Hibernate 4.2.1 in a maven project and I'm using MS SQL JDBC to connect to a SQL Server Database. When I run my class Test I get the following error:

WARN : org.hibernate.internal.util.xml.DTDEntityResolver - HHH000223: Recognized obsolete hibernate namespace http://hibernate.sourceforge.net/. Use namespace http://www.hibernate.org/dtd/ instead. Refer to Hibernate 3.6 Migration Guide!

I need your help friends.

Answer 1

You need to remove <scope>test</scope> from your dependency declaration. You aren't only using the driver for your tests, but also for your actual runtime use.

Specifying <scope>test</scope> will instruct Maven to only load the dependency when running your tests. You should also ask yourself if you really want to use a preview version, and not a officially released version (ie: 6.2.2.jre8).
