SpringCloud 启动"No qualifying bean of type 'javax.servlet.Filter' available"问题

导入别人的springcloud 的eureka服务的时候，启动报错，报错信息是：

Description:

Parameter 0 of method traceFilterRegistration in org.springframework.cloud.netflix.eureka.server.EurekaServerAutoConfiguration required a bean of type 'javax.servlet.Filter' that could not be found.
    - Bean method 'resourceUrlEncodingFilter' in 'FreeMarkerServletWebConfiguration' not loaded because @ConditionalOnEnabledResourceChain did not find class org.webjars.WebJarAssetLocator


Action:

Consider revisiting the conditions above or defining a bean of type 'javax.servlet.Filter' in your configuration.

搜了一下只找到一个办法，而且非常粗鲁：

rm -r $HOME/.m2

也就是删除本地maven仓库里面的所有东西，然后重新下载。没找到好的办法，只能这么干，挂机挂了很久才重新下载回来，结果还真的成功了。
