Question

所以我正在构建一个Spring3.2。3.4.0发布/Hibernate。1.最后一次申请，我得到了以下例外

[2017-03-22 09:29:47860]调试组织。springframework。豆。工厂支持DefaultListableBeanFactory[localhost-startStop-1]忽略FactoryBean类型检查上的bean创建异常：org。springframework。豆。工厂BeanCreationException:创建名为“loginService”的bean时出错（URL[jar:file:/D:/programs/apache-tomcat-7.0.33/webapps/perWeb/WEB-INF/lib/perService-2.0.jar！/applicationContext transactional service.xml]：设置bean属性“target”时无法解析对bean“loginServiceImpl”的引用；嵌套的异常是org。springframework。豆。工厂BeanCreationException:创建名为“loginServiceImpl”的bean时出错，该名称在URL[jar:file:/D:/programs/apache-tomcat-7.0.33/webapps/perWeb/WEB-INF/lib/perService-2.0.jar！/applicationContext simple service.xml]中定义：bean初始化失败；嵌套的异常是org。springframework。豆。ConversionNotSupportedException:无法转换“ma”类型的属性值。刀。impl。GenericDAO“到所需类型”ma。刀。IGenericDAO'表示属性“dao”；嵌套的异常是java。lang.IllegalStateException:无法将[ma.dao.impl.GenericDAO]类型的值转换为属性“dao”所需的[ma.dao.IGenericDAO]类型：找不到匹配的编辑器或转换策略

这是我的bean:loginservice

<bean id="loginService"
        class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
        <property name="transactionManager">
            <ref bean="transactionManagerPER" />

                </prop>
            </props>
        </property>
    </bean>

loginServiceImpl

<bean id="loginServiceImpl"
          class="ma.service.login.LoginService">
        <property name="dao">
            <ref bean="userDAO" />
        </property>
    </bean>

UserDAO

<bean id="userDAO"
        class="ma.dao.impl.GenericDAO">
        <constructor-arg>
            <value>
                ma.dao.mappings.Utilisateur
            </value>

        <property name="sessionFactory">
            <ref bean="sessionFactoryPER" />
        </property>
    </bean>

Utilisateur.爪哇

@Entity
@NamedQueries(

    @ManyToOne
