Java InvalidPropertyException：无效属性'；classDAO'；bean类的：无属性'；classDAO'；

嗨，我一直在尝试在我们的服务器上实现一个新的bean。每次我尝试运行服务器时，它都会抛出此错误

org.springframework.beans.factory.BeanCreationException:创建名为“walletToWalletService”的bean时出错[文件：/opt/WSappl/webapps/axis2/WEB-INF/springjdbc.xml]：初始化 豆荚失败；嵌套异常为org.springframework.beans.InvalidPropertyException:bean类[com.cbas.jdbc.walletToWallet.WalletToWalletServiceImpl]的无效属性“walletToWalletDAO”： 未找到属性“walletToWalletDAO”

下面是springjdbc.xml文件

 <bean id="walletToWalletDAO" class="com.cbas.jdbc.walletToWallet.WalletToWalletDAO">
            <property name="dataSource">
                    <ref bean="dataSource" />
            </property>
    </bean>

    <bean id="walletToWalletService" class="com.cbas.jdbc.walletToWallet.WalletToWalletServiceImpl">
            <property name="walletToWalletDAO">
                    <ref bean="walletToWalletDAO" />
            </property>
    </bean>

您是否声明了变量private WalletToWalletDao WalletToWalletDao；在WalletToWalletServiceImpl中？错误抱怨WalletToWalletServiceImpl中缺少属性。该类的代码在哪里？是否使用基于注释的配置？然后你必须用

@Repository

注释并在spring配置文件中添加

来注释你的

DAO

类。这很尴尬。我只是把walletToWalletDao的房产和walletToWalletDao错卖了。我很抱歉。谢谢@Kalyan的提示。@Deus Levin谢谢你对拼写错误的评论！！！这让我找到了一个setter方法，该方法在重构过程中没有被重命名，这给我带来了类似的问题。
