java.lang.Object
  org.springframework.util.MethodInvoker
      org.springframework.beans.support.ArgumentConvertingMethodInvoker
          org.springframework.scheduling.support.MethodInvokingRunnable

All Implemented Interfaces:

Runnable, BeanClassLoaderAware, InitializingBean

Direct Known Subclasses:

MethodInvokingTimerTaskFactoryBean

public class MethodInvokingRunnable
extends ArgumentConvertingMethodInvoker
implements Runnable, BeanClassLoaderAware, InitializingBean

Adapter that implements the Runnable interface as a configurable method invocation based on Spring's MethodInvoker.

Inherits common configuration properties from MethodInvoker.

Useful to generically encapsulate a method invocation as timer task for java.util.Timer, in combination with a DelegatingTimerTask adapter. Can also be used with JDK 1.5's java.util.concurrent.Executor abstraction, which works with plain Runnables.

Extended by Spring's MethodInvokingTimerTaskFactoryBean adapter for java.util.TimerTask. Note that you can populate a ScheduledTimerTask object with a plain MethodInvokingRunnable instance as well, which will automatically get wrapped with a DelegatingTimerTask.

Since:

1.2.4

Method Detail

setBeanClassLoader

public void setBeanClassLoader(ClassLoader classLoader)

Description copied from interface: 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's InitializingBean.afterPropertiesSet() method or a custom init-method.

Specified by:

setBeanClassLoader in interface BeanClassLoaderAware

Parameters:

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()

resolveClassName

protected Class resolveClassName(String className)
                          throws ClassNotFoundException

Description copied from class: MethodInvoker

Resolve the given class name into a Class.

The default implementations uses ClassUtils.forName, using the thread context class loader.

Overrides:

resolveClassName in class MethodInvoker

Parameters:

className - the class name to resolve

Returns:

the resolved Class

Throws:

ClassNotFoundException - if the class name was invalid

afterPropertiesSet

public void afterPropertiesSet()
                        throws ClassNotFoundException,
                               NoSuchMethodException

Description copied from interface: InitializingBean

Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:

afterPropertiesSet in interface InitializingBean

Throws:

ClassNotFoundException

NoSuchMethodException

run

public void run()

Specified by:

run in interface Runnable

getInvocationFailureMessage

protected String getInvocationFailureMessage()

Build a message for an invocation failure exception.

Returns:

the error message, including the target method name etc
