同学好，感觉还是配置上有问题，这个是访问URL出错还是启动tomcat的时候就出错？ 说的是参数非法。

可以参考

进行搭建

  老师好，早上按参考的检查了一下，tomcat启动没问题，配置步骤也检查了一遍应该没问题，最后run as/maven install出现如下错误
  [ERROR] Plugin org.apache.maven.plugins:maven-war-plugin:2.2 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-war-plugin:jar:2.2: Could not transfer artifact org.apache.maven.plugins:maven-war-plugin:pom:2.2 from/to central (https://repo.maven.apache.org/maven2): Connect to repo.maven.apache.org:443 [repo.maven.apache.org/151.101.40.215] failed: Read timed out -> [Help 1]
  [ERROR] 
  [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
  [ERROR] Re-run Maven using the -X switch to enable full debug logging.
  
  我按照帮助信息[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/PluginResolutionException  稍微看了下说是plugin的问题，按照前两个建议我仔细检查了下pom.xml里面内容跟老师的是一样的，然后第三方maven仓库设置也没问题，下面几个建议没看明白

  run as/maven install没报错了，更新了下仓库配置。然后，浏览器依然404

  解决了，下午把tomcat服务器换成8.0的之后没用谷歌浏览器打开就能看到了，一开始就把我整蒙了,T-T
