I am new to Spring boot architecture. I am trying to create a new spring boot application from the scratch. As a first step, I have installed STS in my machine and also I have the jdk-11 installed and configured in the environment variables section.
I am able to create standalone java applications using STS. But when I try to create a spring-starter project, I am not at all finding any such options in STS(image shown below). Please let me know what I am missing here. Below is the screenshot of my STS.
The problem was with my STS installation that I figured out by following the steps provide by andrewJames in the comments section. After installing the latest version(4.17), the problem got resolved.

I have created a Spring Boot project in Visual Studio Code. My issue is that autocompletion is not working in my application.settings file, it works fine in other parts of project. Any help will be appreciated.

Do you have the necessary plugins/extension installed in your VS Code.
Try installing Spring Boot Tools and try again.
i am still a beginner with spring boot, and i have a bunch of questions.
First of all, do i have to download maven in my pc and add it to my pc path envirement to make spring boot work correctly ?
Secondly, Spring boot wasn't able to work, was doing a hello world app and there were lot of errors on the console one of them is "SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".. why that ? i looked for the error and followed some mvn command line steps "mvn dependency:purge-local-repository", and my app finally worked.. but do i have to run this command everytime i create a spring boot app ? isn't everything supposed to be alright since it's only a hello world app ? ..
Thank you
Yes, you need to have installed maven or gradle in order to run your application. And it needs to be reachable, so you have to configure your system variables accordingly.
You can find more details here.
As per the maven error, maven keeps all the artifacts you need to run your application in a shared folder with all versions, sometimes maven could have corrupted files or a mismatch in version so you need to purge the repository and download artifacts again.
You can find a more detailed answer here.
Even when you are coding a simple application, spring-boot bring up a lot of code for supporting operations you may require, such code is self configured and hidden.
I am new in spring.I imported one spring project in eclipse and try to run with apache tomcat but it is not running.There is no main method in project.It contains only controllers and models and one jsp page.When i tried to run as a java application is shows below dialog. Please help me.I tried all in google for how to run spring project but i can't understand.Please tell me how to do?
Assuming you have added tomcat to your eclipse.
If your project is pure java project then it will not show you the run on server option in eclipe. You need to change project facet and add dynamic web module to it then you can run it on tomcat server from eclipse.Basically project needs to be web project.
After doing above if it gives error or do not run properly, check your project deployment assembly and add projects webapps folder in eclipse.
you need to have a tomcat installed in your eclipse and run it on the server.
Here is a tutorial to do this
You need to install the Web Tools Platform, which has support for the usual Web-application tools.
I don't know if some one asked this but I have a problem that I am working on this tutorial Hello World Example with annotation driven Spring 3 MVC in Eclipse .Now I am very embarrassed to say that how can I make war file to deploy on tomcat. Please guide me in this regard. Thank you
P.S: Just to inform you that I have Tomcat 6.0 and eclipse indigo 3.7
You have many options depending on the environment you're using; the more simple ways can be:
for testing purpose you can reference a Tomcat installation inside your Eclipse in the Severs tab of the J2EE perspective and add your Dynamic Web Project to it; then you can control (start/stop/debug) your server from Eclipse
to build a war to deploy, you can right click the Dynamic Web Project and choose Export War File
I would recommend using Apache Maven as it will help you much as you project will get bigger and your will have a lot of dependencies. You can try it as Eclipse plugin (m2eclipse) or use it from command line.
I have a jboss(5.1.0.GA)/seam(2.2.0.GA) app that gives me a lot of work everytime I need to setup a development environment for it.
What I want is to port the build to maven, and have it setup all the development environment for me(including downloading and configuring the AS).
How could I acomplish something like that? Currently the build is managed by eclipse and has a default java ee project structure(projects for ear, ejb and jsf) so a simple example of porting an eclipse java ee project to maven with the above requeriments will suffice.
I found these two posts which can explain how you can use seam-gen and convert it to use maven.
This might be helpful for you.
