BshScriptFactory
public BshScriptFactory(String scriptSourceLocator)
Create a new BshScriptFactory for the given script source.With this
BshScriptFactory
variant, the script needs to declare a full class or return an actual instance of the scripted object.- 参数:
scriptSourceLocator
- a locator that points to the source of the script. Interpreted by the post-processor that actually creates the script.
BshScriptFactory
public BshScriptFactory(String scriptSourceLocator, @Nullable Class<?>... scriptInterfaces)
Create a new BshScriptFactory for the given script source.The script may either be a simple script that needs a corresponding proxy generated (implementing the specified interfaces), or declare a full class or return an actual instance of the scripted object (in which case the specified interfaces, if any, need to be implemented by that class/instance).
- 参数:
scriptSourceLocator
- a locator that points to the source of the script. Interpreted by the post-processor that actually creates the script.scriptInterfaces
- the Java interfaces that the scripted object is supposed to implement (may benull
)

setBeanClassLoader
public void setBeanClassLoader(ClassLoader classLoader)
从接口复制的说明:BeanClassLoaderAware
Callback that supplies the beanclass 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.- 指定者:
setBeanClassLoader
在接口中BeanClassLoaderAware
- 参数:
classLoader
- the owning class loader
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()
从接口复制的说明:ScriptFactory
Return the business interfaces that the script is supposed to implement.Can return
null
if the script itself determines its Java interfaces (such as in the case of Groovy).- 指定者:
getScriptInterfaces
在接口中ScriptFactory
- 返回:
- the interfaces for the script
requiresConfigInterface
public boolean requiresConfigInterface()
BeanShell scripts do require a config interface.- 指定者:
requiresConfigInterface
在接口中ScriptFactory
- 返回:
- whether the script requires a generated config interface
- 另请参阅:
ScriptFactory.getScriptInterfaces()
getScriptedObject
@Nullable public Object getScriptedObject(ScriptSource scriptSource, @Nullable Class<?>... actualInterfaces) throws IOException, ScriptCompilationException
Load and parse the BeanShell script viaBshScriptUtils
.- 指定者:
getScriptedObject
在接口中ScriptFactory
- 参数:
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
)- 返回:
- the scripted Java object
- 抛出:
IOException
- if script retrieval failedScriptCompilationException
- if script compilation failed- 另请参阅:
BshScriptUtils.createBshObject(String, Class[], ClassLoader)
getScriptedObjectType
@Nullable public Class<?> getScriptedObjectType(ScriptSource scriptSource) throws IOException, ScriptCompilationException
从接口复制的说明: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.
- 指定者:
getScriptedObjectType
在接口中ScriptFactory
- 参数:
scriptSource
- the actual ScriptSource to retrieve the script source text from (nevernull
)- 返回:
- the type of the scripted Java object, or
null
if none could be determined - 抛出:
IOException
- if script retrieval failedScriptCompilationException
- if script compilation failed
requiresScriptedObjectRefresh
public boolean requiresScriptedObjectRefresh(ScriptSource scriptSource)
从接口复制的说明:ScriptFactory
Determine whether a refresh is required (e.g. through ScriptSource'sisModified()
method).- 指定者:
requiresScriptedObjectRefresh
在接口中ScriptFactory
- 参数:
scriptSource
- the actual ScriptSource to retrieve the script source text from (nevernull
)- 返回:
- whether a fresh
ScriptFactory.getScriptedObject(org.springframework.scripting.ScriptSource, java.lang.Class<?>...)
call is required - 另请参阅:
ScriptSource.isModified()
