集成了spring 3，hibernate 3，maven和mysql
我在applicationContext.xml中尝试了不同的sessionFactory。 它有同样的问题。 任何建议都会得到提升！ applicationContext.xml中
${jdbc.dialect} ${hibernate.show_sql} ${hibernate.format_sql} 这是pom.xml。

这是错误的轨道。 我在eclipse中运行它，在tomcat 7服务器上

你有JAR地狱的情况。
无论出于何种原因，这种依赖
org.springframework spring-hibernate3 2.0.8
其中有一个org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean类隐藏了org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean类，即。 同名，在此依赖项中
org.springframework spring-orm 3.2.4.RELEASE
并且该类没有setPackagesToScan方法。 摆脱spring-hibernate3依赖。 spring-orm应该绰绰有余。 您可以在此处下载源代码并自行检查。
我认为问题是属性packagesToScan占用String array而不是简单的String 。 尝试更改属性：
