错误1：8080端口被IIS占用，关闭它
Description:
The Tomcat connector configured to listen on port 8080 failed to start. The port
may already be in use or the connector may be misconfigured.
Action:
Verify the connector's configuration, identify and stop any process that's liste
ning on port 8080, or configure this application to listen on another port.
http://localhost:8080/d.do
HelloWorld.grovy
@RestController
class HelloWorld {
@RequestMapping("/d.do")
String hello() {
"Hello JournalDev World."
}
}
("/d.do")去掉d.do可以用http://localhost:8080访问；路径不对会报下列错误
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
