Java BaseModelAction-class And Method Code Example

BaseModelAction is a abstract class in Logback that provides an implementation of the Action interface, making it easier to create new Action classes. It provides basic functionality for handling events and logging errors. Here's an example of how it might be used to create a new Action class:

import ch.qos.logback.core.spi.ContextAwareBase;

public class MyAction extends ContextAwareBase implements BaseModelAction {
    public void begin(String event, Object origin) {
        // Perform the action
        System.out.println("Event '" + event + "' occurred at " + origin);

    public void end(String event, Object origin) {
        // Perform any necessary cleanup
        System.out.println("Event '" + event + "' finished at " + origin);

In this example, the MyAction class extends the ContextAwareBase and implements the BaseModelAction interface. It overrides the begin() and end() methods, and provides its own implementation for performing the action and cleaning up after the action is finished.

It could be used on logback.xml file as:

  <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
      <new class="com.example.MyAction"/>
  <root level="info">
    <appender-ref ref="console"/>

This way, the begin() and end() methods of the class are going to be invoked when the appender is started and stopped respectively.

It's important to keep in mind that this is just an example of how the BaseModelAction can be used to create new Action classes, and that the actual implementation of your application may vary depending on your specific requirements.
