How to Auto-Start a JAR on Windows After Reboot

Scenario: Deploy a JAR on a Windows server and ensure it runs automatically after the machine reboots.

Implementation steps:

Choose a directory to store the JAR, e.g., D:\www\kaoqinBack, and copy the JAR (e.g., bdkqgl.jar) there.

Verify the JAR runs without errors: java -jar bdkqgl.jar Create a text file (e.g., badao.txt) with the following content:

@echo "公众号:霸道的程序猿"
java -jar d:\www\kaoqinBack\bdkqgl.jar

Save the file and rename its extension to .bat (e.g., badao.bat).

Double‑click the batch file to confirm it opens a command window, prints the text, and launches the JAR without errors.

Automatic startup configuration:

Open the Windows Startup folder, typically located at C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp. If the folder is hidden, enable the display of hidden files.

If the folder does not exist (or is named in Chinese), create a StartUp (or equivalent) directory manually.

Copy the prepared badao.bat into this Startup directory.

After placing the batch file, Windows will execute it automatically on each boot, causing the JAR to start without manual intervention.
