Re-Inject Spring Autowired dependency

Question

I need to reinject a dependency once it is initialized w/o re-initializing of Application Context.

in detail below is what my requirement

if DB is down application should not perform any transaction , once DB is up application should resume.

this is what i am doing

i have created mongoTemplate , autowiring with attr (required=false). so that when application is getting deployed , even though DB is down ,deployment should not fail .

problem :::

but when DB will be up is there any way to reinitialize mongoTemplate and inject it again w/o rebooting server or re-deployment of application.

You should use a Provider for changing dependencies. See When to use javax.inject.Provider in Spring? for more information.

Should probably provide a code example or more guidance than that – Snappawapa Feb 22 '18 at 17:29
