Anil Yadav Thanks for posting your question in Microsoft Q&A. Azure Spring Apps support only 64-bit Java runtime and there is no support for 32-bit JAVA runtime. Therefore, if your Spring Boot application requires a 32-bit JVM, it cannot be deployed to Azure Spring Apps, and you might have to consider other options such as installing 32-bit Java on Azure VM or Azure Web Apps (Windows) etc.
I hope this helps and let me know if any questions.
