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?

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 am converting Java web project into Spring Project. (10 JSP and 5 controllers connecting to DB)
We are using Wildfly server for deployment.
Is there any use of creating Spring Boot project (though i have facilities like actuators, starters etc.)
or
Is it fine to create Spring MVC Project and deploy the war in Wildfly as i am not using any container here and spring boot project will be an overhead? Basically i am finding why should i use spring boot here?
it depends.
Spring boot is just SpringMVC + Tomcat in one JAR (very simplified definition, I know).
If you have an existing and working Wildfly Server, use it. Compile your web app as WAR an deploy it. You will have also better configuraiton, server update and server bugfixing possibilities. At least that was in my case, as my team mates had a lot of experience with Wildfly.
We are using SpringBoot for small pure REST (micro)services (without HTML, JSP), since they are fast to implement and to deploy (just run a jar file). All of these applications have their own Tomcat server - with own PORT. If you want a new Tomcat version you have to recompile your application. This could be a disadvantage (but not realy).
I am new in spring boot. can anyone help me out with this? Why tomcat is not required in spring boot? Any help well be great.
A Spring Boot Application contains the binaries for the server (example, tomcat.jar). It means you can run a web application as a normal Java application.
As you can see in the following text from https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-embedded-web-servers, you can change the server to a server of your choice:
For servlet stack applications, the spring-boot-starter-web includes
Tomcat by including spring-boot-starter-tomcat, but you can use
spring-boot-starter-jetty or spring-boot-starter-undertow instead.
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.
I am learning Spring Boot and wanted to know if there is any way to use Jboss as application server using gradle.
