0000-00-00 00:00:55.497 WARN 12000 --- [ restartedMain] o.s.b.d.a.OptionalLiveReloadServer : Unable to start LiveReload server
reason:
When you use the springboot hot deployment plug-in devtools , and start multiple applications at the same time, the console will report this warning;
The problem is that a port is configured in devtoolsproperties. The default is 35729
public static class Livereload {
private boolean enabled = true;
private int port = 35729;
... }
Multiple ports are in conflict, causing the hot deployment plug-in behind to not take effect.
Solution:
Add the following configuration to the application.properties file:
spring. Devtools. Livereload. Port = 35731 (specified port does not duplicate port)
