Production Mode in Vaadin Spring-Boot

Flow
1

Hi,

I am trying to activate production Mode in my spring-boot application, but I didn’t find any documentation about it. Also I would like to set other parameters, like idle session timeout, etc.

My workaround was to overwrite the parameter in my custom servlet:


https://github.com/datenhahn/ffmobile-map/commit/9b7db70dc12f89c2efc136d397a51fc2d41de2d1

These parameters I would like to overwrite (like with the VaadinServletConfiguration Annotation in “normal” vaadin)

I think that is the way you’ll have to do it at the moment - or that’s how I’ve also done it. Personally, I’d like to be able to configure those settings through application properties, would be consistent with other configuration.

If you are using Spring Boot, you can set most (but not all) of the servlet properties by adding them to your application.properties file. You can find the supported properties
here
. In your case, you’d use:

  • vaadin.servlet.resourceCacheTime
  • vaadin.servlet.productionMode
  • vaadin.servlet.heartbeatInterval
  • vaadin.servlet.closeIdleSessions

I created a wiki page for
Vaadin Spring tips
 and added this as a basis. Feel free to add new stuff to that page. These should definitely be in the Book as well, I’ll tip Marko about this.

cheers,

Thanks, it worked with the application.properties now. I tried that before, but maybe I used the wrong keys.

Thank you for the writeup and also maati for adding this to the Vaadin Spring tips Wiki entry. Valuable information.

I tried

#vaadin.servlet.resourceCacheTime
vaadin.servlet.productionMode=true
#vaadin.servlet.heartbeatInterval
vaadin.servlet.closeIdleSessions=true;

and it seems I am still stuck in

Vaadin is running in DEBUG MODE.
Add productionMode=true to web.xml to disable debug features.
===========================================================**

all othe rproperites froms ame application.properties are read just fine… any ideas?
I am using

	<dependency>
		    <groupId>org.springframework.boot</groupId>
		    <artifactId>spring-boot-starter-tomcat</artifactId>
		    <version>2.0.5.RELEASE</version>
		</dependency>

and


		<vaadin.version>11.0.1</vaadin.version>
		<component.version>1.1.0.beta1</component.version>

Use the following in your application.yml to set production mode

vaadin:
  productionMode: false

Of course, if you wanted production mode to be enabled, set the value to true

sorry to sound weird but… I am using SpringBoot and I have no idea where an yml file could be… I am using maven and springboot, (yml this looks like gradle? I am not using gradle )
I have tried in application.properties

#vaadin.servlet.resourceCacheTime
vaadin.servlet.productionMode=true
#vaadin.servlet.heartbeatInterval
vaadin.servlet.closeIdleSessions=true;

in vain

I passed it OK on java cmd line
-Dvaadin.productionMode=true

problem solved

application.yml lives in src/main/resources. IDK if one can use both application.properties and application.yml, but I chose to use yml. The two files both serve the same purpose in Spring.

I got it to work by changing vaadin.servlet.productionMode=true to vaadin.productionMode=true

I tried everything from this topic to run application in production mode… but all the time I see DEBUG MODE. Any chance for help?

my application.properties

server.port = 8090
vaadin.servlet.productionMode=true
#vaadin.productionMode=true
vaadin.servlet.heartbeatInterval=60
vaadin.servlet.closeIdleSessions=true

Using java still dont work:

java -jar application.jar -Dvaadin.productionMode=true

Try setting

vaadin.productionMode=true
vaadin.heartbeatInterval=60
vaadin.closeIdleSessions=true

in application.properties. Then build with

mvn clean package -Pproduction-mode
15

strange with

vaadin.productionMode=true
vaadin.heartbeatInterval=60
vaadin.closeIdleSessions=true

works now … thx
