Spring Boot - Fundamentals

You want to run your Spring Boot app as a standalone jar. Which command correctly runs the jar file named app.jar?

Amvn run app.jar

Bjava run app.jar

Cgradle run app.jar

Djava -jar app.jar

Step-by-Step Solution

Solution:

Step 1: Recall how to run a jar file in Java
The standard command to run an executable jar is 'java -jar filename.jar'.
Step 2: Check other options for correctness
The mvn and gradle commands are for build tools, not for running jar files directly. 'java run app.jar' is invalid Java command syntax.
Final Answer:
java -jar app.jar -> Option D
Quick Check:
Run jar with 'java -jar' = java -jar app.jar [OK]

Quick Trick: Run jar files with 'java -jar filename.jar' [OK]
