public class GroovyScriptFactory
extends Object
implements ScriptFactory, BeanClassLoaderAware

ScriptFactory implementation for a Groovy script.

Typically used in combination with a ScriptFactoryPostProcessor; see the latter's javadoc} for a configuration example.

Constructor Summary
GroovyScriptFactory(String scriptSourceLocator)           Create a new GroovyScriptFactory for the given script source.
GroovyScriptFactory(String scriptSourceLocator, GroovyObjectCustomizer groovyObjectCustomizer)           Create a new GroovyScriptFactory for the given script source, specifying a strategy interface that can create a custom MetaClass to supply missing methods and otherwise change the behavior of the object.

 

Method Summary
protected  Object	executeScript(Class scriptClass)           Instantiate the given Groovy script class and run it if necessary.
Object	getScriptedObject(ScriptSource scriptSource, Class[] actualInterfaces)           Loads and parses the Groovy script via the GroovyClassLoader.
Class	getScriptedObjectType(ScriptSource scriptSource)           Determine the type of the scripted Java object.
Class[]	getScriptInterfaces()           Groovy scripts determine their interfaces themselves, hence we don't need to explicitly expose interfaces here.
String	getScriptSourceLocator()           Return a locator that points to the source of the script.
boolean	requiresConfigInterface()           Groovy scripts do not need a config interface, since they expose their setters as public methods.

Constructor Detail

GroovyScriptFactory

public GroovyScriptFactory(String scriptSourceLocator)

Create a new GroovyScriptFactory for the given script source.

We don't need to specify script interfaces here, since a Groovy script defines its Java interfaces itself.

Parameters:

scriptSourceLocator - a locator that points to the source of the script. Interpreted by the post-processor that actually creates the script.

---

GroovyScriptFactory

public GroovyScriptFactory(String scriptSourceLocator,
                           GroovyObjectCustomizer groovyObjectCustomizer)

Create a new GroovyScriptFactory for the given script source, specifying a strategy interface that can create a custom MetaClass to supply missing methods and otherwise change the behavior of the object.

We don't need to specify script interfaces here, since a Groovy script defines its Java interfaces itself.

Parameters:

scriptSourceLocator - a locator that points to the source of the script. Interpreted by the post-processor that actually creates the script.

groovyObjectCustomizer - a customizer that can set a custom metaclass or make other changes to the GroovyObject created by this factory (may be null)

Method Detail

setBeanClassLoader

public void setBeanClassLoader(ClassLoader classLoader)

Description copied from interface: BeanClassLoaderAware

Callback that supplies the bean class loader to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean's InitializingBean.afterPropertiesSet() method or a custom init-method.

Specified by:

setBeanClassLoader in interface BeanClassLoaderAware

Parameters:

classLoader - the owning class loader; may be null in which case a default ClassLoader must be used, for example the ClassLoader obtained via ClassUtils.getDefaultClassLoader()

---

getScriptSourceLocator

public String getScriptSourceLocator()

Description copied from interface: ScriptFactory

Return a locator that points to the source of the script. Interpreted by the post-processor that actually creates the script.

Typical supported locators are Spring resource locations (such as "file:C:/myScript.bsh" or "classpath:myPackage/myScript.bsh") and inline scripts ("inline:myScriptText...").

Specified by:

getScriptSourceLocator in interface ScriptFactory

Returns:

the script source locator

See Also:

ScriptFactoryPostProcessor.convertToScriptSource(java.lang.String, org.springframework.core.io.ResourceLoader), ResourceLoader

---

getScriptInterfaces

public Class[] getScriptInterfaces()

Groovy scripts determine their interfaces themselves, hence we don't need to explicitly expose interfaces here.

Specified by:

getScriptInterfaces in interface ScriptFactory

Returns:

null always

---

requiresConfigInterface

public boolean requiresConfigInterface()

Groovy scripts do not need a config interface, since they expose their setters as public methods.

Specified by:

requiresConfigInterface in interface ScriptFactory

Returns:

whether the script requires a generated config interface

See Also:

ScriptFactory.getScriptInterfaces()

---

getScriptedObject

public Object getScriptedObject(ScriptSource scriptSource,
                                Class[] actualInterfaces)
                         throws IOException,
                                ScriptCompilationException

Loads and parses the Groovy script via the GroovyClassLoader.

Specified by:

getScriptedObject in interface ScriptFactory

Parameters:

scriptSource - the actual ScriptSource to retrieve the script source text from (never null)

actualInterfaces - the actual interfaces to expose, including script interfaces as well as a generated config interface (if applicable; may be null)

Returns:

the scripted Java object

Throws:

IOException - if script retrieval failed

ScriptCompilationException - if script compilation failed

See Also:

GroovyClassLoader

---

getScriptedObjectType

public Class getScriptedObjectType(ScriptSource scriptSource)
                            throws IOException,
                                   ScriptCompilationException

Description copied from interface: ScriptFactory

Determine the type of the scripted Java object.

Implementations are encouraged to cache script metadata such as a generated script class. Note that this method may be invoked concurrently and must be implemented in a thread-safe fashion.

Specified by:

getScriptedObjectType in interface ScriptFactory

Parameters:

scriptSource - the actual ScriptSource to retrieve the script source text from (never null)

Returns:

the type of the scripted Java object, or null if none could be determined

Throws:

IOException - if script retrieval failed

ScriptCompilationException - if script compilation failed

---

executeScript

protected Object executeScript(Class scriptClass)
                        throws ScriptCompilationException

Instantiate the given Groovy script class and run it if necessary.

Parameters:

scriptClass - the Groovy script class

Returns:

the result object (either an instance of the script class or the result of running the script instance)

Throws:

ScriptCompilationException - in case of instantiation failure

---

toString

public String toString()

Overrides:

toString in class Object
