这个怎么解决，谢谢

[tommore]

public class baseDaoImpl 声明是不是错了应该是:
public class baseDaoImpl implements baseDao
也就是没有实现接口，所以注入失败。

[cxw3152]

baseDaoImpl 这个类有没有实现baseDao接口。

[cxw3152]

把除了basedao以外的注入全部注释掉 看是否还有错误 如果没有的话按下面的方式配置一下 。。看看可以不
<bean id="adminService" class="com.sysbase.service.impl.adminServiceImpl" parent="baseDao" >
<property name="basedao" ref="basedao"/>
</bean>

Failed to convert property value of type 'com.sysbase.dao.baseDaoImpl' to required type 'com.sysbase.dao.baseDao' for property 'basedao'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [com.sysbase.dao.baseDaoImpl] to required type [com.sysbase.dao.baseDao] for property 'basedao':
意思是说com.sysbase.dao.baseDaoImpl不能赋值给com.sysbase.dao.baseDao，应该baseDaoImpl实现接口baseDao，这样才可以赋值。

[幻想多巴胺]

谢谢各位了，是这个原因 baseDaoImpl 这个类有没有实现baseDao接口。

[花落成泥徒伤悲]

多谢大神们，我的问题解决了，就是忘了写实现借口了，晕死！
