使用Spring的应用程序中出现的问题进行全面的问答.
我正在尝试使用Spring为webapp自动装配一些bean(用于依赖注入).一个控制器bean包含另一个bean,而另一个bean又拥有另一组bean的hashmap.目前,地图只有一个条目.当我在tomcat中运行并调用该服务时,我得到一个错误,说第二个bean(保存在控制器中)不是唯一的
No unique bean of type [com.hp.it.km.search.web.suggestion.SuggestionService] is defined: expected single matching bean but found 2: [suggestionService, SuggestionService]

我无法看到我在两次定义bean的位置,但是我是Spring的新手并且自动装配,所以我可能会遗漏一些基本的东西.下面列出的xml和2类的源代码......
