我通过从您的 server.xml 复制单个更改，在工作的 Tomcat 配置上重现了您的错误:

更改是从 pattern 复制的<Valve> 的属性(property)server.xml 屏幕截图中的元素:

pattern="%h %l %u %t "%r" %s %b"

该值是无效的 XML，因为它包含嵌套引号 ("%r")。

修复很简单:用 character entity reference 替换嵌套引号等价物，因此 pattern属性看起来像这样:

pattern="%h %l %u %t "%r" %s %b"

完成更改后，您应该能够添加 Tomcat 服务器。

附注我在您的 server.xml 文件中注意到的另一个不相关的差异是 prefix 的值<Valve> 的属性元素是 "localhost_access_log."但是 Tomcat 9 默认是 "localhost_access_log" (没有尾随句点)。
