Answer 2

package com.memedia.ad.dao;import com.memedia.ad.entity.AdContent;public interface IADContentDao extends IBaseDao<AdContent> {}
package com.memedia.ad.dao.impl;import org.springframework.stereotype.Repository;import com.memedia.ad.dao.IADContentDao;
import com.memedia.ad.entity.AdContent;@Repository("adContentDao")
public class ADContentDaoImpl extends BaseDaoImpl<AdContent> implements IADContentDao {}

Answer 3

<context:component-scan base-package="com.aa.*" use-default-filters="false">
<context:include-filter expression="org.springframework.stereotype.Controller" type="annotation" />
</context:component-scan>
需要加这个。packagesToScan是扫描实体类的。

Answer 4

加了没用啊，会不会是我hibernate-core.jar 和 spring-core.jar版本低了啊

Answer 5

        <property name="packagesToScan" value="com.memedia.ad" />
这样就好了,没有.*,它会扫描com.memedia.ad包下的所有实体,但不包括子包
如果要包括子包,需要写成com.memedia.ad*  注意ad与*之前没有点.
很多人会犯的错误.

Answer 6

那请问下ad*找到的是ad包下的字包吗
