We use Gradle build file that includes node component (React.js application) and Java/Grails with spring boot on the backend.
I expect React app to use a configured spring boot port 8092 to get bundle.js and other assets.
After Gradle, grails, and spring boot upgrade, I am getting the below error:
"Could not access webpack-dev-server at http://localhost:3001". After the "yarn start" react application is working.
What would be a way to diagnose why the spring boot port is not used?

I have a Maven-Java project having both Spring boot and Dropwizard application packages. Can I run the Dropwizard application alone? If yes how it can be done?
consider, I have package com.project.springboot containing spring boot application and com.project.dropwizard package containing dropwizard application, help me how I can run dropwizard app alone.
Everytime I run java -jar target/jarfile.jar com.package.dropwizard server config.yml It's starting spring boot application. Anyone please explain why?
When starting/relaunching a Spring Boot App and the app runs on a port which was already in use before I got an error:
Web server failed to start. Port 8092 was already in use.
So, everytime I am starting a Spring Boot App I have to switch server.port in application.properties.
Note: Because I do not have the Run as "Spring Boot App" I use the work around mentioned here to start it:
First Answer, How to run Spring Boot web application in Eclipse itself?
Is there a solution to avoid switching ports every time?
Thanks a lot!
We are working on spring boot application (backend) and angular6 (frontend)
To deploy our application, we used compute engine of google cloud platform.
We install Java 8, spring boot cli, and postgreSQL, our database.
When we run the application locally to the Virtual machine, everything is ok.
To deploy the application, we follow these steps for configuration:
But at least, we cannot get the application running,
here the screenshot:
Your help is more than welcome!
I have a web application created using Spring boot and I am using Spring Tool Suite(STS) for developing it. If my understanding is correct, tomcat is internally embedded in STS and I can run/debug the application from STS with the help of Application.java.
Now my doubts are, when we run the application by running a java class as 'Spring Boot App'
What is the deployment deliverable?(ear/war)
Where exactly the deliverable getting deployed? I have searched
everywhere in STS directories and could find it
If there is nothing like this, then how is it working?
Do this make sense or am I wrong with my understanding?
Your understanding about Spring Boot is wrong.
The embedded Tomcat is included on your application, when you use Spring Boot.
Spring Boot generates a .jar file. When the application is started, Spring knows how to bootstrap a Tomcat instance for you
If you are using the "Run" command on STS, there is no deliverable yet. The main method on Application.java has everything that is need for Spring run your application
Spring Boot is a project dedicated to create stand-alone Spring applications. As I said on first item, Spring Boot knows everything that is need to bootstrap a new Tomcat instance and run your application. You don't need an application server when working with Spring Boot, Spring provides by a embed Tomcat/Jetty or Undertow. The Tomcat is INSIDE your application with your code, not an external application server.
Update
Sorry for not being clear in my question, I am developing a Spring project with the next dependencies
Spring Boot
Spring Data
Mysql
wsdl
In the project I exposed soap Web services with Spring Data for persistence, I have to use RMI for support of application desktop.
I tried the following :
Integrate in the same project Spring and RMI (using RMI Register ) successfully but when I tried use Spring annotations obviously not working.
I'm searching when I found that Spring have support for RMI using XML configuration but I need the configuration in annotations.
My question How to would implement RMI in my project?
I'm using latest version in all dependencies
