Remove JNDI from Spring initialization

Question

I'm loading Spring application in maven tomcat plugin. I'm not using Spring boot.

On loading I'm getting debug logs of failing to load JNDI properties, for example:

Can I disable/ignore JNDI in my spring projects?

Answer 1

It's a good read: what is JNDI?

Basic use of JNDI is to allows distributed applications to look up services in an abstract, resource-independent way.

To disable JNDI

create a spring.properties file in src/main/resources (ignore if already created) and add this value spring.jndi.ignore=true
