-- 添加 -->???? <!-- 配置業(yè)務(wù)層的類 -->???????????? <bean id="addService" class="com.zhang.service.addService">???? <property name="addDao" ref="addDao"></property>??? </bean>?????????????????????????????????????????? <!-- 配置Dao的類 -->????????????????????????????????????? <bean id="addDao" class="com.zhang.dao.addDao">???
報錯了
???????? </bean>Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'addDao' of bean class [com.zhang.service.addService]: Bean property 'addDao' is not writable or has an invalid setter method. Did you mean 'adao'?

Did you mean 'adao'?你的類里面取名是這個，而你想用addDao，所以報錯了，你檢查一下你的名稱是否一致，我的之前也報這個錯誤，原因就是多了個空格，真的嚴(yán)格--，希望對你有幫助
