title: Spring.datasource.initialize=false not working
body: <p>I am working on spring boot and batch application. 
  Due to batch, the application tries to connect to datasource
  with <code>spring-boot:run</code>.
  I want to stop that and tried <code>spring.datasource.initialize=false</code></p>
  
  <p>Along with this also put <code>spring.batch.job.enabled=false</code></p>
  
  <p>While the second one works fine, it seems the first one is ignored.</p>
  
  <p>Could someone let me know if there is a way to stop db connection on startup?
  Thanks in advance</p>
