## Class MethodInvokingRunnable

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

- All Implemented Interfaces:
    Runnable, Aware, 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`.

    - #### 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
