GroovyScriptExecutingMessageProcessor

public GroovyScriptExecutingMessageProcessor(ScriptSource scriptSource)

Create a processor for the given ScriptSource that will use a DefaultScriptVariableGenerator.

Parameters:

scriptSource - The script source.

public GroovyScriptExecutingMessageProcessor(ScriptSource scriptSource, ScriptVariableGenerator scriptVariableGenerator)

Create a processor for the given ScriptSource that will use the provided ScriptVariableGenerator.

Parameters:

scriptSource - The script source.

scriptVariableGenerator - The variable generator.

Method Details

setCustomizer

public void setCustomizer(GroovyObjectCustomizer customizer)

Sets a GroovyObjectCustomizer for this processor.

Parameters:

customizer - The customizer.

setCompileStatic

public void setCompileStatic(boolean compileStatic)

Specify the boolean flag to indicate if the GroovyClassLoader's compiler should be customised for the CompileStatic hint for the provided script.

More compiler options can be provided via setCompilerConfiguration(CompilerConfiguration) overriding this flag.

Parameters:

compileStatic - the compile-static boolean flag.

setCompilerConfiguration

public void setCompilerConfiguration(org.codehaus.groovy.control.CompilerConfiguration compilerConfiguration)

Specify the CompilerConfiguration options to customize the Groovy script compilation. For example the CompileStatic and ImportCustomizer are the most popular options.

Parameters:

compilerConfiguration - the Groovy script compiler options to use.

Since:

4.3

getScriptSource

protected ScriptSource getScriptSource(Message<?> message)

Description copied from class: AbstractScriptExecutingMessageProcessor

Subclasses must implement this method to create a script source, optionally using the message to locate or create the script.

Specified by:

getScriptSource in class AbstractScriptExecutingMessageProcessor<Object>

Parameters:

message - the message being processed

Returns:

a ScriptSource to use to create a script

afterPropertiesSet

public void afterPropertiesSet()

Specified by:

afterPropertiesSet in interface InitializingBean

executeScript

protected Object executeScript(ScriptSource scriptSource, Map<String,Object> variables)

Description copied from class: AbstractScriptExecutingMessageProcessor

Subclasses must implement this method. In doing so, the execution context for the script should be populated with the provided script variables.

Specified by:

executeScript in class AbstractScriptExecutingMessageProcessor<Object>

Parameters:

scriptSource - The script source.

variables - The variables.

Returns:

The result of the execution.
