localhost上的服务器Tomcat v9.0服务器无法在eclipse中启动

问题描述 投票：1回答：3

我一直在尝试编写基本的spring mvc程序，只是为了显示一个静态的html页面。我遇到了一个我无法解决的错误，因为这是我的第一个spring-mvc程序。我使用的是spring5.15和apache tomcat9。我正在尝试运行我的代码，但总是在下面得到例外：

我想添加的几个指针：1。我没有使用maven或任何依赖管理工具。 2.我将添加Spring 5.1.5发行版中的所有jar，javax.servlet.jsp.jstl-1.2.1，common-logging-1.2.jar和javax.servlet.jsp.jstl-api-1.2.1。

这是使用最新版本的Tomcat 9.0.16的问题。这个版本的Tomcat最近有一些变化。

但是，我们可以通过以下方式解决此问题。

在您的web.xml文件中，在第8行添加此条目

<absolute-ordering />

这应该出现在<display-name>条目之后。

有关<absolute-ordering>标签的详细信息，请参阅此链接

只是为了完整性，这里是完整的文件进行比较

也许你没有在项目中添加commons-logging作为依赖项

只是为了更多的说明从以下两个链接读取

我在Tomcat 9中面临同样的问题，我将其更改为Tomcat 8.5并且还添加了它并且它有效
