azure 应用服务与 spring 启动：等待响应预热

Question

I deploy a spring boot application on azure (app service), but it takes many time to get started (20 minutes sometimes), I always have in the logs this line with many occurences:

Waiting for response to warmup request for container myapp_id_on_azure_0_917c0e77. Elapsed time = 326.0884541 sec

I seems to wait something to effectively start the application... but what? Anyone have tips?

FYI: I execute: java -jar /home/site/wwwroot/my_app.jar for starting my application. I not define any server port in application.properties on my spring boot application. I also verify that on " general settings " of the app service the option " always on " is enabled...

Answer 1

FYI: I execute: java -jar /home/site/wwwroot/my_app.jar

From this sentence, I can probably guess that you are using the linux platform.

I think your question is meaningless, in the absence of any log. So there should be no one who can give you a direct and effective solution, but can only provide you with troubleshooting ideas.

Troubleshooting steps

1. If you use windows platform, you should add web.config under wwwroot folder.

   Instead of executing java -jar /home/site/wwwroot/my_app.jar in the command line.

2. If you use linux paltform, and your webapp use myapp.jar file, so you should use Java SE , like below.

   

3. Whatever paltform you use, you shold check application log, find error message, it will help you solve the issues.
