maven导包不当的error

作为一个渣渣,我只能说我再不记一下,我觉得我自己都开始藐视自己的记忆力,自己也看过配置文件的讲解,但一般不是写doem的时候,我都没有配过,以前的过程,自己都忘了,连最基本tomcat起的是web.xml我都能不记得,真的是把自己秒成渣渣,配置好web.xml,起tomcat就遇到下面的问题.我这个和aop有什么关系呢??

在网上找各种解决方法,再次无语中:原因竟是maven导入的jar包版本冲突,以前犯过这个错,但是这次我真想...

最后的结果:我当时只是有一个版本比较低,就是运行不过,我不知道该如何是好,包的不兼容问题,......,这次长记性了,spring相关的包我一定要版本相同或者用{spring-version}来解决是最好的

                <dependency><groupId>org.springframework</groupId><artifactId>spring-test</artifactId><version>4.3.8.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-core</artifactId><version>4.3.8.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-web</artifactId><version>4.3.8.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-webmvc</artifactId><version>4.3.8.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-beans</artifactId><version>4.3.8.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context</artifactId><version>4.3.8.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-context-support</artifactId><version>4.3.8.RELEASE</version></dependency><dependency><groupId>org.springframework</groupId><artifactId>spring-tx</artifactId><version>4.3.8.RELEASE</version></dependency>

下面这个问题也是我无语的地方,网上有各种解决方案,但是不适合我这种,功夫不负我呀,我看到一句版本太低,不合tom6兼容,我一想我是tom8,我就马上找自己的servlet-api发现版本真的低问题就解决了,

总之一句话你的服务器版本高的话,你的jar包的版本也要高,否则不兼容,再次见识了,兼容的必要性
