eclipse 下配置spring项目常年遇到各种问题,有不小心配置文件写错的,或者eclipse难以言语的bug,特此记录一下遇到的bug及解决办法,以示警惕 (￣ー￣)
本人正在做的项目需要引入spring-mobile框架,然后maven加入了依赖:
<dependency> <groupId>org.springframework.mobile</groupId> <artifactId>spring-mobile-device</artifactId> <version>1.1.5.RELEASE</version> </dependency>项目构建然后启动tomcat but 出现以下错误

1.使用版本一致的依赖 2.没有一致版本则删掉(本人使用的方法)
搜的一些资料大概讲的都是配置文件的问题 项目出问题也大都在配置上 所以仔细检查spring及springMVC的配置文件很重要 使用Maven引入依赖也要注意版本问题
spring-mobile真的找不到一致的版本只能默默删掉依赖,寻找别的出路，有没有知道解决办法的同学下方留言谢谢
