tiene más problemas para recomponer la hibernación con spring3. esta vez dice que la conexión es nula ya que el dialecto no está configurado, lo cual está en mi archivo hibernate.cfg.xml.La conexión no puede ser nula cuando 'hibernate.dialect' no está configurado
aquí es la excepción completo:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mySessionFactory' defined in URL [file:war/WEB-INF/datasource-config.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Connection cannot be null when 'hibernate.dialect' not set

Aquí está mi thats dataSource-config.xml ets hasta la SessionFactory

Y a continuación es el archivo hibernate.cfg.xml
<?xml version='1.0' encoding='utf-8'?>

Como puede ver, el dialecto se está configurando.
edición: mis database.properties archivo
# DB properties file
database.url=jdbc:mysql://localhost:3306/freedom
database.driver=com.mysql.jdbc.Driver
database.user=root
database.password=password
database.maxConnections=25
edición: aquí hay una traza completa. acceder a la base de datos podría ser el problema, pero puedo acceder a él con éxito a través del símbolo del sistema?

No creo que u puede depurar un archivo XML. He intentado depurar el código de Java actual pero nunca lo alcanza, ya que todavía está tratando de organizar los beans y su contexto de aplicación – jonney
Spring e Hibernate están escritos en "código real de Java" también. El stacktrace revela qué clases y métodos están involucrados en la construcción de SessionFactory. Simplemente establece un punto de quiebre allí para descubrir dónde van las cosas mal? – meriton
Lo sentimos, pero no puedes depurar libs a menos que importes todo el proyecto de la clase lib en tu proyecto. cosas como "org.springframework.beans.factory" no se pueden depurar a través de libs. – jonney
