mac Idea Tomcat 报错 Cannot open URL. Please check this URL is correct:

配置host xx.xxx.xxx.xxx hostname

tomcat 配置url http://hostname:8080
端口号要配置 8080 不能像windows一样配置80

Start by reviewing the host mapping and Tomcat URL configuration described in the issue, then reproduce the “Cannot open URL” error on macOS using port 8080. Done means the configured hostname opens the Tomcat service successfully; the issue does not name repository files or tests to inspect.
