Class GroovyScriptFactory
- All Implemented Interfaces:
 Aware,BeanClassLoaderAware,BeanFactoryAware,ScriptFactory
ScriptFactory implementation
 for a Groovy script.
 Typically used in combination with a
 ScriptFactoryPostProcessor;
 see the latter's javadoc for a configuration example.
 
Note: Spring 4.0 supports Groovy 1.8 and higher.

GroovyScriptFactory
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, @Nullable 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.- 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 benull)- See Also:
 
 - 
GroovyScriptFactory
public GroovyScriptFactory(String scriptSourceLocator, @Nullable org.codehaus.groovy.control.CompilerConfiguration compilerConfiguration) 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.- Parameters:
 scriptSourceLocator- a locator that points to the source of the script. Interpreted by the post-processor that actually creates the script.compilerConfiguration- a custom compiler configuration to be applied to the GroovyClassLoader (may benull)- Since:
 - 4.3.3
 - See Also:
 - 
GroovyClassLoader(ClassLoader, CompilerConfiguration)
 
 - 
GroovyScriptFactory
public GroovyScriptFactory(String scriptSourceLocator, org.codehaus.groovy.control.customizers.CompilationCustomizer... compilationCustomizers) Create a new GroovyScriptFactory for the given script source, specifying a strategy interface that can customize Groovy's compilation process within the underlying GroovyClassLoader.- Parameters:
 scriptSourceLocator- a locator that points to the source of the script. Interpreted by the post-processor that actually creates the script.compilationCustomizers- one or more customizers to be applied to the GroovyClassLoader compiler configuration- Since:
 - 4.3.3
 - See Also:
 - 
CompilerConfiguration.addCompilationCustomizers(org.codehaus.groovy.control.customizers.CompilationCustomizer...)ImportCustomizer

setBeanFactory
Description copied from interface:BeanFactoryAwareCallback that supplies the owning factory to a bean instance.Invoked after the population of normal bean properties but before an initialization callback such as
InitializingBean.afterPropertiesSet()or a custom init-method.- Specified by:
 setBeanFactoryin interfaceBeanFactoryAware- Parameters:
 beanFactory- owning BeanFactory (nevernull). The bean can immediately call methods on the factory.- See Also:
 
 - 
setBeanClassLoader
Description copied from interface:BeanClassLoaderAwareCallback that supplies the beanclass loaderto a bean instance.Invoked after the population of normal bean properties but before an initialization callback such as
InitializingBean'sInitializingBean.afterPropertiesSet()method or a custom init-method.- Specified by:
 setBeanClassLoaderin interfaceBeanClassLoaderAware- Parameters:
 classLoader- the owning class loader
 - 
getGroovyClassLoader
public groovy.lang.GroovyClassLoader getGroovyClassLoader()Return the GroovyClassLoader used by this script factory. - 
buildGroovyClassLoader
Build aGroovyClassLoaderfor the givenClassLoader.- Parameters:
 classLoader- the ClassLoader to build a GroovyClassLoader for- Since:
 - 4.3.3
 
 - 
getScriptSourceLocator
Description copied from interface:ScriptFactoryReturn 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:
 getScriptSourceLocatorin interfaceScriptFactory- Returns:
 - the script source locator
 - See Also:
 
 - 
getScriptInterfaces
Groovy scripts determine their interfaces themselves, hence we don't need to explicitly expose interfaces here.- Specified by:
 getScriptInterfacesin interfaceScriptFactory- Returns:
 nullalways
 - 
requiresConfigInterface
public boolean requiresConfigInterface()Groovy scripts do not need a config interface, since they expose their setters as public methods.- Specified by:
 requiresConfigInterfacein interfaceScriptFactory- Returns:
 - whether the script requires a generated config interface
 - See Also:
 
 - 
getScriptedObject
@Nullable public Object getScriptedObject(ScriptSource scriptSource, @Nullable Class<?>... actualInterfaces) throws IOException, ScriptCompilationException Loads and parses the Groovy script via the GroovyClassLoader.- Specified by:
 getScriptedObjectin interfaceScriptFactory- Parameters:
 scriptSource- the actual ScriptSource to retrieve the script source text from (nevernull)actualInterfaces- the actual interfaces to expose, including script interfaces as well as a generated config interface (if applicable; may benull)- Returns:
 - the scripted Java object
 - Throws:
 IOException- if script retrieval failedScriptCompilationException- if script compilation failed- See Also:
 - 
GroovyClassLoader
 
 - 
getScriptedObjectType
@Nullable public Class<?> getScriptedObjectType(ScriptSource scriptSource) throws IOException, ScriptCompilationException Description copied from interface:ScriptFactoryDetermine 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:
 getScriptedObjectTypein interfaceScriptFactory- Parameters:
 scriptSource- the actual ScriptSource to retrieve the script source text from (nevernull)- Returns:
 - the type of the scripted Java object, or 
nullif none could be determined - Throws:
 IOException- if script retrieval failedScriptCompilationException- if script compilation failed
 - 
requiresScriptedObjectRefresh
Description copied from interface:ScriptFactoryDetermine whether a refresh is required (for example, through ScriptSource'sisModified()method).- Specified by:
 requiresScriptedObjectRefreshin interfaceScriptFactory- Parameters:
 scriptSource- the actual ScriptSource to retrieve the script source text from (nevernull)- Returns:
 - whether a fresh 
ScriptFactory.getScriptedObject(org.springframework.scripting.ScriptSource, java.lang.Class<?>...)call is required - See Also:
 
 - 
executeScript
@Nullable protected Object executeScript(ScriptSource scriptSource, Class<?> scriptClass) throws ScriptCompilationException Instantiate the given Groovy script class and run it if necessary.- Parameters:
 scriptSource- the source for the underlying scriptscriptClass- 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
