org.springframework.beans.factory.BeanCreationException: Error creating bean with name '***'


错误如下：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'newsService' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException:
Could not instantiate bean class [com.zhym.service.NewsService]: Specified class is an interface

Caused by:

org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [com.zhym.service.NewsService]: Specified class is an interface

错误原因：首先确保service接口的实现类没有错，然后查看applicationContext.xml中对此service的声明，是否把bean中class后的包名中的service实现了写成了service接口。比如service接口名:UserService.java，其实现类为UserServiceImpl.java，而你的bean写成了<bean name="userService" class="com.zyy.service.UserService><!--省略中。。。--></bean>，这里只需把class改为：class="com.zyy.service.UserServiceImpl"
