Answer 1

stacktrace的这一部分让我怀疑您使用的是Hibernate4:

Caused by: java.lang.ClassCastException:     
org.springframework.orm.hibernate3.LocalDataSourceConnectionProvider cannot be cast to org.hibernate.service.jdbc.connections.spi.ConnectionProvider

如果使用Hibernate4，则需要使用org.springframework.orm.hibernate4.localDataSourceConnectionProvider而不是org.springframework.orm.hibernate3.localDataSourceConnectionProvider。
