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 be null)

方法详细资料

setBeanClassLoader

public void setBeanClassLoader(ClassLoader classLoader)

指定者:

setBeanClassLoader 在接口中 org.springframework.beans.factory.BeanClassLoaderAware

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

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

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 via BshScriptUtils.

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)

返回:

the scripted Java object

抛出:

IOException - if script retrieval failed

ScriptCompilationException - if script compilation failed

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 (never null)

返回:

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

抛出:

IOException - if script retrieval failed

ScriptCompilationException - 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's isModified() method).

指定者:

requiresScriptedObjectRefresh 在接口中 ScriptFactory

参数:

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

返回:

whether a fresh ScriptFactory.getScriptedObject(org.springframework.scripting.ScriptSource, java.lang.Class<?>...) call is required
