类 GroovyScriptFactory

构造器详细资料

• 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.

  参数:

  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.

  参数:

  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)

  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.

  参数:

  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 be null)

  Create a new GroovyScriptFactory for the given script source, specifying a strategy interface that can customize Groovy's compilation process within the underlying GroovyClassLoader.

  参数:

  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

• setBeanFactory

  public void setBeanFactory​(BeanFactory beanFactory)

  从接口复制的说明: BeanFactoryAware
  Callback that supplies the owning factory to a bean instance.

  指定者:

  setBeanFactory 在接口中 BeanFactoryAware

  参数:

  beanFactory - owning BeanFactory (never null). The bean can immediately call methods on the factory.

  public void setBeanClassLoader​(ClassLoader classLoader)

  从接口复制的说明: BeanClassLoaderAware
  Callback that supplies the bean class loader to a bean instance.

  指定者:

  setBeanClassLoader 在接口中 BeanClassLoaderAware

  参数:

  classLoader - the owning class loader

• getGroovyClassLoader

  public groovy.lang.GroovyClassLoader getGroovyClassLoader()

  Return the GroovyClassLoader used by this script factory.

• buildGroovyClassLoader

  protected groovy.lang.GroovyClassLoader buildGroovyClassLoader​(@Nullable
                                                                 ClassLoader classLoader)

  Build a GroovyClassLoader for the given ClassLoader.

  参数:

  classLoader - the ClassLoader to build a GroovyClassLoader for

  从以下版本开始:

  4.3.3

• getScriptSourceLocator

  public String getScriptSourceLocator()

  从接口复制的说明: 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...").

  指定者:

  getScriptSourceLocator 在接口中 ScriptFactory

  返回:

  the script source locator

• getScriptInterfaces

  @Nullable
  public Class<?>[] getScriptInterfaces()

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

  指定者:

  getScriptInterfaces 在接口中 ScriptFactory

  返回:

  null always

• requiresConfigInterface

  public boolean requiresConfigInterface()

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

  指定者:

  requiresConfigInterface 在接口中 ScriptFactory

  返回:

  whether the script requires a generated config interface

  ScriptFactory.getScriptInterfaces()

• getScriptedObject

  @Nullable
  public Object getScriptedObject​(ScriptSource scriptSource,
                                  @Nullable

  Loads and parses the Groovy script via the GroovyClassLoader.

  指定者:

  getScriptedObject 在接口中 ScriptFactory

  参数:

  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)
