我试图从注入的EntityManager中解开Hibernate Session,因为我需要使用Hibernate的原生Criteria API.
当我尝试使用Criteria时,我得到以下异常：

但是,当我使用EntityManager本身的Query api时,一切正常.
我的配置：
db.xml
spring-beans-3.0.xsd
http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.3.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
