从我搜索的内容来看，我似乎错过了一个库，所以这是我的POM

如果你们能帮助我找出哪个Lib，我会感激不尽。 但有人可以教如何调试这种错误吗？ 我正在使用Intelij Idea 13
这是mvn依赖的输出：三个

答案 0 :(得分：2)
将在Spring 3.2.1中引入此类seems（来自自标签）。尝试将spring.version更改为3.2.1.RELEASE（以升级包含此类的spring-beans.jar）。
答案 1 :(得分：2)
要解决此类问题，请在findjar.com或grepcode.com中搜索该课程
the report from grepcode，在这种情况下NoUniqueBeanDefinitionException为{{3}}。
在那里我们可以看到该类不在spring-beans jar的3.2.0版本中，并且是最早的版本3.2.1.RELEASE。
然后使用mvn dependency:tree检查项目中使用的版本，并相应地进行调整，在这种情况下升级到至少3.2.1.RELEASE。
