and this is my application.properties file.
server.port=0
and this is how I build my project to Jar :
mvn -> clean -> compile -> package
and I can run this application on my Windows computer and its working just fine! but my problem is in the Linux server when I run this application with systemed this is the log and it says it was successful but it's not working
INFO 20351 --- [ main] trationDelegate$BeanPostProcessorChecker : Bean 'org.springframework.hateoas.config.HateoasConfiguration' of type [org.springframework.hateoas.config.HateoasConfiguration$$EnhancerBySpringCGLIB$$b190a49] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)

and this is my
netstat -ltnpa | grep -i --colour LISTEN
log from 41940 port
tcp6 0 0 :::41940 :::* LISTEN 20351/java
but now i want to send a request to this port with example.com:41940/myrequest but its not working and server is not respondig
=================== EDIT i edit the server.port=0 to 8090
and this is the result of
curl -XGET localhost:8090
curl -XGET localhost:8090 % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0100 93 0 93 0 0 325 0 --:--:-- --:--:-- --:--:-- 326 { "_links" : { "profile" : { "href" : "http://localhost:8090/profile" } } }
