可以看到最主要的错误为：

org.apache.catalina.LifecycleException: Failed to start component 
    
    java.lang.IllegalArgumentException: Invalid <url-pattern> as in servlet mapp

一开始被第一个误导了，百度了很久找了很多方法也没用。这里也将找到的第一个的解决方法汇总以下：

① 端口占用导致的启动失败：[https://blog.csdn.net/baidu9883/article/details/102142703][https_blog.csdn.net_baidu9883_article_details_102142703]

②修改Tomcat 文件：[https://blog.csdn.net/weixin\_42310074/article/details/108375196][https_blog.csdn.net_weixin_42310074_article_details_108375196]

③jar包下载缺损导致的启动失败：[https://blog.csdn.net/yan3013216087/article/details/86558292][https_blog.csdn.net_yan3013216087_article_details_86558292]

④ Tomcat缓存问题：[https://www.cnblogs.com/xiedongshan/p/4686247.html][https_www.cnblogs.com_xiedongshan_p_4686247.html]

我自己的解决方法，直接百度搜索第二个错误：

发现是url-pattern的 url 忘记加 /

@WebServlet(value="as",asyncSupported = true)

改正

@WebServlet(value="/as",asyncSupported = true)
