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:
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=""> 
"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:
class MyBeanImpl { Integer someProperty String otherProperty
   SpringSecurityService springSecurityService  or def springSecurityService
