说明如下:有一个公共的dao层接口(IDAO)及其实现类(DAOImpl)和service层接口(IManager)及其实现类(ManagerImpl)

IDAO.java如下:

public interface IDAO {
public void add(Object obj);

}

DAOImpl.java如下:

public class DAOImpl implements IDAO {
@Autowired
protected HibernateTemplate ht;

public void add(Object obj) {
ht.save(obj);
}

}

IManager.java如下:

public interface IManager {
public void add(Object obj);

}

ManagerImpl.java如下:

public class ManagerImpl implements IManager {
@Autowired
protected IDAO iDAO;

public void add(Object obj) {
iDAO.add(obj);
}

}

现在有一个area类,以及dao层接口实现类,service层接口实现类,分别继承以上相应的接口或者类,AreaManagerImpl.java代码如下:

public class AreaManagerImpl extends ManagerImpl implements IAreaManager {
@Autowired

@Qualifier("iDAO")
private IAreaDAO areaDAO;

//此方法为AreaDAO接口方法

public List<Area> getAreaListByFather(Integer father) {
return areaDAO.getAreaListByFather(father);
}

}

===========================主要JAVA文件结束=====================

spring配置:

<context:annotation-config />

启动tomcat后报以上的异常,求各位大神,小弟不胜感激,谢谢了

private com.cn.common.area.IAreaDAO com.cn.common.area.service.AreaManagerImpl.areaDAO; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No unique bean of type [com.cn.common.area.IAreaDAO] is defined: Unsatisfied dependency of type [interface com.cn.common.area.IAreaDAO]: expected at least 1 matching bean

引用

public class AreaManagerImpl extends ManagerImpl implements IAreaManager {
@Autowired
@Qualifier("iDAO")
private IAreaDAO areaDAO;

改成

public class AreaManagerImpl extends ManagerImpl implements IAreaManager {
  @Autowired
  @Qualifier("areaDAO")
  private IAreaDAO areaDAO;

此处注入的是areaDao
