老师您好，我在访问demo1时一直无法正确访问到，我想请问一下是什么原因，以及

之前学习servlet时有配置版本是apache-tomcat-9.0.55，现在插件配的是tomcat7，maven里面只配置tomcat7就能使用tomcat了吗？
还有之前讲解servlet，tomcat配置端口是8888，现在tomcat7插件是8080，两者是否会冲突？
两个tomcat版本不一样是不是会导致无法访问的问题。

老师老师，我的会出现这种情况，查意思好像是插件有问题，但是我是按着上节课设置插件的方式操作的，反复看了几次，步骤没错，还可能在哪出问题了？

想借楼给其他学习的小伙伴提醒，不要使用太新的jdk版本进行学习，因为有很多东西不兼容会导致结果不符合预期，包括中文乱码，tomcat启动异常等问题。血和泪的教训，我一直以为是我的问题，结果是jdk的问题。

maven课程的老师能换一下吗？讲的什么？完全不仔细，最基础的设置都不讲清楚，怎么跟着代码敲，敲出来全是错的。

视频8分多，内层for循环逻辑上或许不太对。

如果字段包含多个敏感词，那或许就只能替换掉最后一个敏感词。

我试着改了一下：

for (String sensitiveWord : sensitiveWords)
    if (value.contains(sensitiveWord))
        value = value.replaceAll(sensitiveWord, "***");
model.put(key,value);
