Spring批处理-创建Bean时出错

我想创建一个内存jobrepository，我得到了这个异常，你知道我为什么会得到这个异常吗

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jobExplorerInitial' defined in class path resource [fr/rsi/gdficoba/batch/integrationinitial/job/datasource.xml]: Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'com.sun.proxy.$Proxy22 implementing org.springframework.batch.core.repository.JobRepository,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised' to required type 'org.springframework.batch.core.repository.support.MapJobRepositoryFactoryBean' for property 'repositoryFactory'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [com.sun.proxy.$Proxy22 implementing org.springframework.batch.core.repository.JobRepository,org.springframework.aop.SpringProxy,org.springframework.aop.framework.Advised] to required type [org.springframework.batch.core.repository.support.MapJobRepositoryFactoryBean] for property 'repositoryFactory': no matching editors or conversion strategy found

我的配置是

<bean id="repositoryFactory"
    class="org.springframework.batch.core.repository.support.MapJobRepositoryFactoryBean">
        <property name="transactionManager" ref="transactionManager" />
    </bean>
<bean id="jobExplorerInitial" class="org.springframework.batch.core.explore.support.MapJobExplorerFactoryBean>
        <property name="repositoryFactory" ref="repositoryFactory" />
    </bean>

您必须添加一个“&”：

<property name="repositoryFactory" ref="&amp;repositoryFactory"/>
