Examples of org.springframework.core.DefaultParameterNameDiscoverer

org.springframework.core.DefaultParameterNameDiscoverer
Default implementation of the {@link ParameterNameDiscoverer} strategy interface,using the Java 8 standard reflection mechanism (if available), and falling back to the ASM-based {@link LocalVariableTableParameterNameDiscoverer} for checkingdebug information in the class file.
Further discoverers may be added through {@link #addDiscoverer(ParameterNameDiscoverer)}. @author Juergen Hoeller @since 4.0 @see StandardReflectionParameterNameDiscoverer @see LocalVariableTableParameterNameDiscoverer

   * and adds a specifically configured {@link AspectJAdviceParameterNameDiscoverer}.
