  参数:

  classLoader - the class loader to use for script engine detection

• StandardScriptEvaluator

  public StandardScriptEvaluator​(ScriptEngineManager scriptEngineManager)

  Construct a new StandardScriptEvaluator for the given JSR-223 ScriptEngineManager to obtain script engines from.

  参数:

  scriptEngineManager - the ScriptEngineManager (or subclass thereof) to use

方法详细资料

• setLanguage

  public void setLanguage​(String language)

  Set the name of the language meant for evaluating the scripts (e.g. "Groovy").

  This is effectively an alias for "engineName", potentially (but not yet) providing common abbreviations for certain languages beyond what the JSR-223 script engine factory exposes.

  setEngineName(java.lang.String)

• setEngineName

  public void setEngineName​(String engineName)

  Set the name of the script engine for evaluating the scripts (e.g. "Groovy"), as exposed by the JSR-223 script engine factory.

  从以下版本开始:

  4.2.2

  另请参阅:

  setLanguage(java.lang.String)

• setGlobalBindings

  public void setGlobalBindings​(Map<String,​Object> globalBindings)

  Set the globally scoped bindings on the underlying script engine manager, shared by all scripts, as an alternative to script argument bindings.

  从以下版本开始:

  4.2.2

  另请参阅:

  evaluate(ScriptSource, Map), ScriptEngineManager.setBindings(Bindings), SimpleBindings

• setBeanClassLoader

  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.

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

  指定者:

  setBeanClassLoader 在接口中 BeanClassLoaderAware

  参数:

  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()

• evaluate

  public Object evaluate​(ScriptSource script)

  从接口复制的说明: ScriptEvaluator
  Evaluate the given script.

  指定者:

  evaluate 在接口中 ScriptEvaluator

  参数:

  script - the ScriptSource for the script to evaluate

  返回:

  the return value of the script, if any

• evaluate

  public Object evaluate​(ScriptSource script,
                         Map<String,​Object> argumentBindings)

  从接口复制的说明: ScriptEvaluator
  Evaluate the given script with the given arguments.

  指定者:

  evaluate 在接口中 ScriptEvaluator

  参数:

  script - the ScriptSource for the script to evaluate

  argumentBindings - the key-value pairs to expose to the script, typically as script variables (may be null or empty)

  返回:

  the return value of the script, if any

• getScriptEngine

  protected ScriptEngine getScriptEngine​(ScriptSource script)

  Obtain the JSR-223 ScriptEngine to use for the given script.

  参数:

  script - the script to evaluate

  返回:

  the ScriptEngine (never null)
