tomcat启动报错：Annotation-specified bean name 'pickingCallback'

Question

在google和baidu上没有找到答案，环境也调试过了。java7，tomcat7和spring3.2.14，不知道哪里错了？来问下大神门。

Answer 1

我觉得是之前的错误 导致spring容器中有残留的bean 再次修改正确之后 重新运行也会报错，现在你修改了配置文件 可能之前的暂留还在 但是已经不会影响他运行了 我的问题是一直报错重复 然后我把文件名加了一个下划线，神奇的就好使了 但是我可以确定 项目中绝对不存在重名的文件 只是spring容器的问题而已

Answer 2

解决了，其实我都没发现错误在哪里。重新改了改配置文件，就好了。

Answer 3

pickingCallback这个类我也不知道是spring哪里引用的，貌似是jdk8里的一个类

Answer 4

Annotation-specified bean name'pickingCallback' for beanclass [com.sun.j3d.utils.picking.behaviors.PickingCallback] conflicts with existing, non-compatible bean definition of same name andclass [com.sun.j3d.utils.behaviors.picking.PickingCallback]

我外语不好，但是看到这个报错，第一个感觉就是 pickingCallback 这个bean有问题...

Answer 5

是不是按bean name注入的？[com.sun.j3d.utils.picking.behaviors.PickingCallback] conflicts with existing, non-compatible bean definition of same name andclass
[com.sun.j3d.utils.behaviors.picking.PickingCallback]按类型注入，或者改类名吧。
