I have a spring boot project. How can I make the java spring boot project run on my local machine without using any application (Intellij IDEA, Eclipse, Heroku, Docker etc.)? I can do this using jar file on command line, but I want to use a different method. How can I do that on windows ?

A couple of options, depending on how advanced you want to make it.
Here's a related answer on how to use Launch4J: How do I bundle a JRE in my JAR, so that it can run on systems without Java?
You can also look into using https://www.advancedinstaller.com, which allows helps you create installation wizards for different operating systems, including setting registry values, etc.
Make sur that the JRE is installed on your machine (which is the case if you'r running .jar files from cmd) then open the jar file as any windows program, if you want to generate an executable .exe from your file then use launch4j.
GraalVM
Another more modern and efficient approach than launch4j would be to use GraalVM.
- Install GraalVM
- Install some C developer environment like Visual Studio
- Run:
gu install native-image
After compiling your Java code with javac compile as a native image
javac YourClass.javanative-image YourClass
Now you have an efficient executable that can run on its own anywhere.
At least this is how you do it manually.
You have a library for Spring, spring-native, to help you. Or you can develop your project using Quarkus instead, which can build a native image out of the box
