尝试为 dao hibernate 运行 Junit 测试给我以下错误

Question

错误信息是：-Error creating bean with name 'agencyDetailsInterfaceService' defined in class path resource。

下面的堆栈跟踪：

Answer 1

您是否将属性agencyBatchOutService 声明为实现类型而不是接口IAgencyBatchOutService？。

如果你需要使用实现，使用<aop:config proxy-target-class="true">强制Spring使用cglib代理。
