Getting application configuration in doWithSpring closure using Grails 3 application

Grails 3 allows authors to use start hooks similar to those provided by Grails 2 plugins. I look at the definition of beans in a doWithSpring closure, and I would like to pass values ​​to a new bean based on some configuration values. However, I cannot figure out how to get the grailsApplication instance or application configuration. How do you do this with Grails 3?

Your plugin should have grails.plugins.Plugin extended, which defines the getConfig() method. See https://github.com/grails/grails-core/blob/9f78cdf17e140de37cfb5de6671131df3606f2fe/grails-core/src/main/groovy/grails/plugins/Plugin.groovy#L65 .

You can simply refer to the config property.

Similarly, you can refer to the inherited property grailsApplication , which is defined in https://github.com/grails/grails-core/blob/9f78cdf17e140de37cfb5de6671131df3606f2fe/grails-core/src/main/groovy/grails/plugins/lugin .

I hope this helps.

Under Grails 3, I took the recommendation of Jeff Scott Brown and used GrailsApplicationAware instead:

Here's how you are going to configure the bean:

So, in your new plugin descriptor, you need to change the grails 2 def doWithSpring style to ClosureDoWithSpring, as shown below:

Notice that in Grails 2 we introduced grailsApplication, in grails 3 all we do is declare a bean:

 /* def doWithSpring = { sshConfig(SshConfig) { grailsApplication = ref('grailsApplication') } } */ Closure doWithSpring() { {-> sshConfig(SshConfig) } }

Now, to get your plugin configuration:

Src / main / groovy / grails / plugin / remotessh / sshconfig sshconfig.groovy

 package grails.plugin.remotessh import grails.core.GrailsApplication import grails.core.support.GrailsApplicationAware class SshConfig implements GrailsApplicationAware { GrailsApplication grailsApplication public ConfigObject getConfig() { return grailsApplication.config.remotessh ?: '' } }

grails.plugin.remotessh.RemoteSsh.groovy:

 String Result(SshConfig ac) throws InterruptedException { Object sshuser = ac.config.USER ?: '' Object sshpass = ac.config.PASS ?: '' ...

Now your configuration object is passed to the groovy src classes. The end user application would pass the sshConfig bean as follows:

 class TestController { def sshConfig def index() { RemoteSSH rsh = new RemoteSSH() .... def g = rsh.Result(sshConfig) }

Edited to add, just found this :) which is a relevant or recurring question:
