I'm trying to disable jmx so that i don't get org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mbeanExporter'anymore.
I've found a partial answer saying that I should include this in the application.properties file:
spring.datasource.jmx-enabled=false
So I created the file with that one line. But how do I make sure that Spring acutally reads it? Do I need to edit something in spring.xml? If so, where?
You need to disable the setting in your application.properties file (it is automatically turned on if not set). Either edit or create this file: src/main/resources/config/application.properties
That is for a maven project, so if not in maven, just put 'resources' at the same level as your java folder.
You will just need this single line in the file (it can be blank otherwise):
spring.jmx.enabled=false
If you want to add other settings, here are all the options: http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html
