我在Spring AOP和下面的Spring配置文件嘗試我的手:BeanNotOfRequiredTypeException與Spring AOP

當我運行的代碼,我得到錯誤說:
異常在線程「主」 org.springframework.beans.factory.BeanNotOfRequiredTypeException: 豆命名爲‘埃迪’必須 [com.springinaction.Instrumentalist]類型, 卻被類型[$ Proxy4]實際上在 組織.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:348) 在 org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:193) 在 org.springframework.context .support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1008) 在 com.springinaction.Main.main(Main.java:12)
如果我在評論彈簧配置文件<aop:config>
元件它是完全運行狀態。 。
爲什麼它是怎麼回事?
感謝Pourquoi Litytestdata爲您詳細的解答...... 好像你知道有很多關於SpringIdol競爭:) 我想我需要再次瞭解代理類... 感謝您的澄清... – javanoob 2010-08-28 15:50:48
