Class AbstractSmartLifecycle

java.lang.Object

io.microsphere.spring.context.lifecycle.AbstractSmartLifecycle

All Implemented Interfaces:

org.springframework.context.Lifecycle, org.springframework.context.Phased, org.springframework.context.SmartLifecycle

Direct Known Subclasses:

LoggingSmartLifecycle

public abstract class AbstractSmartLifecycle
extends Object
implements org.springframework.context.SmartLifecycle

Abstract base class for implementing SmartLifecycle strategies.

This class provides a skeletal implementation of the SmartLifecycle interface, making it easier to create custom lifecycle beans with specific startup and shutdown logic.

Key Features

• Centralizes common lifecycle state management.
• Offers phase-based control for startup and shutdown order.
• Ensures consistent lifecycle behavior across implementations.

Example Usage

 public class MyCustomLifecycle extends AbstractSmartLifecycle {
     private boolean running = false;

     @Override
     protected void doStart() {
         // Initialize resources
         running = true;
     }

     @Override
     protected void doStop() {
         // Release resources
         running = false;
     }

     @Override
     public boolean isRunning() {
         return running;
     }
 }
 

This class is designed to be extended, requiring subclasses to implement the abstract methods doStart() and doStop() to define custom behavior.
