Question

我正在研究支付网关集成，而我一直停留在这一点上。我得到错误。我尝试了所有可能的解决方案，但无法继续。帮助我确定解决方案。我有servlet-context.xml，其中我通过

导入pg-context.xml。

<beans:import resource="classpath:pg-context.xml" />

In this file pg-context.xml , you define like below

<beans:bean id="pgService" class="com.majesco.dcf.pg.service.PGService" >
        <beans:property name="pgService" ref="PGService" /> 
    </beans:bean>

But where you are getting **ref="PGService"**? Is there any bean you define with name "PGService"?

BeanCreationException：创建类路径资源中定义的名称为“ pgService”的bean时出错
