public class GroovyBeanDefinitionReader extends AbstractBeanDefinitionReader implements groovy.lang.GroovyObject
This bean definition reader also understands XML bean definition files, allowing for seamless mixing and matching with Groovy bean definition files.
Typically applied to a
DefaultListableBeanFactory
or a GenericApplicationContext
,
but can be used against any BeanDefinitionRegistry
implementation.
import org.hibernate.SessionFactory import org.apache.commons.dbcp.BasicDataSource def reader = new GroovyBeanDefinitionReader(myApplicationContext) reader.beans { dataSource(BasicDataSource) { // <--- invokeMethod driverClassName = "org.hsqldb.jdbcDriver" url = "jdbc:hsqldb:mem:grailsDB" username = "sa" // <-- setProperty password = "" settings = [mynew:"setting"] } sessionFactory(SessionFactory) { dataSource = dataSource // <-- getProperty for retrieving references } myService(MyService) { nestedBean = { AnotherBean bean -> // <-- setProperty with closure for nested bean dataSource = dataSource } } }
You can also load resources containing beans defined in a Groovy script using
either the AbstractBeanDefinitionReader.loadBeanDefinitions(Resource...)
or
AbstractBeanDefinitionReader.loadBeanDefinitions(String...)
method, with a script looking similar to
the following.
import org.hibernate.SessionFactory import org.apache.commons.dbcp.BasicDataSource beans { dataSource(BasicDataSource) { driverClassName = "org.hsqldb.jdbcDriver" url = "jdbc:hsqldb:mem:grailsDB" username = "sa" password = "" settings = [mynew:"setting"] } sessionFactory(SessionFactory) { dataSource = dataSource } myService(MyService) { nestedBean = { AnotherBean bean -> dataSource = dataSource } } }
