使用Spring进行JUnit测试时使用Hibernate 4进行转换异常

我使用org.springframework.orm.hibernate4.LocalSessionFactoryBean类创建了sessionFactory bean，并使用org.springframework.orm.hibernate4.HibernateTransactionManager类创建了transactionManager bean .

在执行JUnits测试时，将显示以下内容 .

“引起：org.springframework.beans.ConversionNotSupportedException：无法将类型'java.lang.String'的属性值转换为属性'sessionFactory'所需的类型'org.hibernate.SessionFactory';嵌套异常是java.lang.IllegalStateException ：无法将类型[java.lang.String]的值转换为属性'sessionFactory'所需的类型[org.hibernate.SessionFactory]：找不到匹配的编辑器或转换策略“ .

Hibernate Core依赖版本是4.3.9 .

请指教 .

下面是我的JUnit测试的datasource.xml . 测试在dev配置文件下运行 . 虽然确切的.xml代码可以顺利地在主应用程序的 生产环境 配置文件下运行 .
