I believe that this is related to the local JMX agent and the configuration of the hosts file. First, ensure your hosts file has an appropriate mapping of localhost to 127.0.0.1. Then, add the following VM option:
-Djava.rmi.server.hostname=localhost
If you are using IntelliJ, you can find instructions for adding this VM option here.

I'm doing a spring boot project , and this project can run successfully in the eclipse and war use cmd. However it failed to start in the linux environment.
I have used netstat -ano | grep 28081 , the port is not in use.

Description:
The Tomcat connector configured to listen on port 28081 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 listening on port 28081, or configure this application to listen on another port.
Local war instruction is :
C:\tmp\jdk1.8.0_31_x64\jre\bin\java -DaEnv=UAT -Denv=UAT -Da.domainName=pfDomain -Drealtime.nodeName=Node1 -jar C:\aServices.war -Djava.protocol.handler.pkgs=javax.net.ssl -Djavax.net.ssl.keyStore=C:\SSL-keystore.UAT.jks -Djavax.net.ssl.trustStore=C:\SSLTrust.UAT.jks
The application can start successfully.
In the application.properties file , the ssl location is wrong , it should like this :
server.ssl.key-store=/opt/a/etc/SSL-keystore.jks
server.ssl.trust-sotre=/opt/a/etc/certs/SSLTrust.jks
I am using default docker image of MongoDB and trying to connect using simple spring Boot application on windows box.
mongoDB image is getting stared correctly

What i am missing here ?
Not a MongoDB expert, but a moderate Docker user speaking: It looks like you are not publishing the port MongoDB runs by default: 27017. That's why your spring application could not get a connection and throws this exception:
Exception in monitor thread while connecting to server 192.168.99.100:27017
So you may try publishing the port by using -p 27017:27017when initiating mongo container.
I use embedded undertow server in my web project. It works well in Idea with listening port 80 and 443, following the log in idea.
2018-08-04 11:32:31.394 INFO 4933 --- [ main] o.s.b.w.e.u.UndertowServletWebServer : Undertow started on port(s) 443 (https) 80 (http) with context path ''
But when I run it on my ubuntu server or local command line:
java -jar xxxx.jar
Output log is
Undertow started on port(s) 443 (https) with context path ''
wihout listening port 80. I can only visit the site by inputing https://xxxx
handly.
I compared the log. The server log print the extra two lines

I din't know what's wrong. Any answer is helpful. Thanks.
I have a Spring Boot application which runs on a remote server. When I build it to work over HTTP everything works fine. But when I am trying to setup SSL the application not work. It doesn't throw errors or anything. But I can't access any page in the browser (I have tried https://www.example.com, https://www.example.com:8443, https://example.com etc).
I have built keystore.jks on remote server machine from certificate.crt (which I have bought for my domain on ssl).
I have the following application.properties:
server.port=8443
server.ssl.key-store=classpath:keystore.jks
server.ssl.key-store-password=PASSWORD
server.ssl.key-password=PASSWORD
I have tried different configurations but no results. The same story happens when I trying to run it on my local machine (I thought it is because of I am going to localhost when the certificate is for example.com but maybe it is the same problem).
Here is the server output:
INFO 11041 --- [ main] o.e.jetty.util.ssl.SslContextFactory : x509=X509#2a492f2a(jetty,h=[www.example.com, example.com],w=[]) for >SslContextFactory#3277e499(jar:file:/root/application.jar!/BOOT->INF/classes!/keystore.jks,null)

So everything seems to be fine but it doesn't work.
Problem solved. It was just wrong generated keystore.jks.
I developed a Spring boot application with MongoDB. While the MongoDB in the localhost, it works fine, but when the MongoDB is in different the server, I changed the setting in application.properties as
spring.data.mongodb.uri=mongodb://192.168.7.31/gcp
spring.data.mongodb.username=xxx
spring.data.mongodb.password=xxxxxxx
the application faileds as it still looks for the mongoDB in localhost
