Grails Configuring your own Bean or Groovy Object

Configuring Additional Beans

Using the Spring Bean DSL

You can easily register new (or override existing) beans by configuring them in grails-app/conf/spring/resources.groovy which uses the Grails Spring DSL. Beans are defined inside a beans property (a Closure):

beans = {
    // beans here
}

As a simple example you can configure a bean with the following syntax:

import my.company.MyBeanImpl



beans = {
    myBean(MyBeanImpl) {
        someProperty = 42
        otherProperty = "blue"
    }
}

Once configured, the bean can be auto-wired into Grails artifacts and other classes that support dependency injection (for example BootStrap.groovy and integration tests) by declaring a public field whose name is your bean's name (in this case myBean):

class ExampleController {

     def myBean
     …
}






Referencing Existing Beans

Beans declared in resources.groovy or resources.xml can reference other beans by convention. For example if you had a BookService class its Spring bean name would be bookService, so your bean would reference it like this in the DSL:

beans = {
    productUtility ( ProductUtility )
            {
          someProperty = 42
          otherProperty = "blue"
          springSecurityService = ref ( "springSecurityService" )
            }
}


or like this in XML:

"myBean" class="my.company.MyBeanImpl"> 

"someProperty" value="42" />
    "otherProperty" value="blue" />

  "springSecurityService" ref="springSecurityService" />

The bean needs a public setter for the bean reference (and also the two simple properties), which in Groovy would be defined like this:

package my.company

class MyBeanImpl {
    Integer someProperty
    String otherProperty
    
   SpringSecurityService springSecurityService  or def springSecurityService 
}

Grails Debugging Enable Intelj Idea

Step 1:-
Add in config.groovy

plugin.platformCore.events.catchFlushExceptions = true

Step 2:-
Add in buildconfig.groovy

grails.project.fork = [
        test: false,
        run: false
]


That's It, 
 Just run in debug mode..  [ click debug button, instead of run button/from menu]
