public class GroovyWebApplicationContext
extends AbstractRefreshableWebApplicationContext

WebApplicationContext implementation which takes its configuration from Groovy bean definition scripts and/or XML files, as understood by an GroovyBeanDefinitionReader. This is essentially the equivalent of GenericGroovyApplicationContext for a web environment.

By default, the configuration will be taken from "/WEB-INF/applicationContext.groovy" for the root context, and "/WEB-INF/test-servlet.groovy" for a context with the namespace "test-servlet" (like for a DispatcherServlet instance with the servlet-name "test").

The config location defaults can be overridden via the "contextConfigLocation" context-param of ContextLoader and servlet init-param of FrameworkServlet. Config locations can either denote concrete files like "/WEB-INF/context.groovy" or Ant-style patterns like "/WEB-INF/*-context.groovy" (see PathMatcher javadoc for pattern details). Note that ".xml" files will be parsed as XML content; all other kinds of resources will be parsed as Groovy scripts.

Note: In case of multiple config locations, later bean definitions will override ones defined in earlier loaded files. This can be leveraged to deliberately override certain bean definitions via an extra Groovy script.

For a WebApplicationContext that reads in a different bean definition format, create an analogous subclass of AbstractRefreshableWebApplicationContext. Such a context implementation can be specified as "contextClass" context-param for ContextLoader or "contextClass" init-param for FrameworkServlet.

Method Detail

loadBeanDefinitions

protected void loadBeanDefinitions(DefaultListableBeanFactory beanFactory)
                            throws BeansException,
                                   java.io.IOException

Loads the bean definitions via an GroovyBeanDefinitionReader.

Specified by:

loadBeanDefinitions in class AbstractRefreshableApplicationContext

Parameters:

beanFactory - the bean factory to load bean definitions into

Throws:

BeansException - if parsing of the bean definitions failed

java.io.IOException - if loading of bean definition files failed

See Also:

GroovyBeanDefinitionReader, initBeanDefinitionReader(org.springframework.beans.factory.groovy.GroovyBeanDefinitionReader), loadBeanDefinitions(org.springframework.beans.factory.support.DefaultListableBeanFactory)

initBeanDefinitionReader

protected void initBeanDefinitionReader(GroovyBeanDefinitionReader beanDefinitionReader)

Initialize the bean definition reader used for loading the bean definitions of this context. Default implementation is empty.

Can be overridden in subclasses.

Parameters:

beanDefinitionReader - the bean definition reader used by this context

loadBeanDefinitions

protected void loadBeanDefinitions(GroovyBeanDefinitionReader reader)
                            throws java.io.IOException

Load the bean definitions with the given GroovyBeanDefinitionReader.

The lifecycle of the bean factory is handled by the refreshBeanFactory method; therefore this method is just supposed to load and/or register bean definitions.

Delegates to a ResourcePatternResolver for resolving location patterns into Resource instances.

Throws:

java.io.IOException - if the required Groovy script or XML file isn't found

AbstractRefreshableApplicationContext.refreshBeanFactory(), AbstractRefreshableWebApplicationContext.getConfigLocations(), AbstractApplicationContext.getResources(java.lang.String), AbstractRefreshableWebApplicationContext.getResourcePatternResolver()

getDefaultConfigLocations

protected java.lang.String[] getDefaultConfigLocations()

The default location for the root context is "/WEB-INF/applicationContext.groovy", and "/WEB-INF/test-servlet.groovy" for a context with the namespace "test-servlet" (like for a DispatcherServlet instance with the servlet-name "test").

Overrides:

getDefaultConfigLocations in class AbstractRefreshableConfigApplicationContext

Returns:

an array of default config locations, if any
