我有一个项目正在使用spring来创建bean并对其自己的类进行组件扫描。然后我将一个Jar包含在构建路径中，用于我需要添加内容的另一个项目。我可以整天创建bean，但是当我进行组件扫描时，它似乎没有做任何事情。
我从这个
开始<context:component-scan base-package="com.company.mainPackage.dao.hibernate" />
然后改为
<context:component-scan base-package="com.company.mainPackage.dao.hibernate" />
<context:component-scan base-package="com.company.jarPackage.dao.hibernate" />
那没有用，所以我尝试了这个
<context:component-scan base-package="com.company.mainPackage.dao.hibernate, com.company.jarPackage.dao.hibernate" />
显示的唯一错误是我的bean无法进行自动装配。来自＆＃34; mainPackage＆＃34;的课程可以找到，但不能来自＆＃34; jarPackage＆＃34;。
两个包中的所有类都使用@Repository注释。
我也试过删除Jar并直接将项目包含在eclipse中的构建路径上但是没有改变。
显然构建路径正常，因为我可以创建单个bean。
