Custom plug-in factory


There are two ways to customize the plug-in factory:
  • Configure the plug-in factory through the @PluginFactory annotation. The annotation parameters are explained as follows:

    Sample code:

        @PluginFactory(pluginHome = "${root}/plugins")
        public class DemoPluginFactory extends DefaultPluginFactory {
        }
    
        // 或者
    
        @PluginFactory(pluginHome = "${root}/plugins",
                autoscanPackages = {"com.company", "cn.company"},
                automatic = true,
                includedClassPath = false,
                listenerClass = DemoPluginEventListener.class)
        public class DemoPluginFactory extends DefaultPluginFactory {
        }
  • Instantiation via factory configuration object

    Create factory configuration object:

        DefaultPluginConfig _conf = new DefaultPluginConfig();
        _conf.setPluginHome(new File(RuntimeUtils.replaceEnvVariable("${root}/plugins")));
        _conf.setAutomatic(true);
        _conf.setAutoscanPackages(Arrays.asList("com.company", "cn.company"));
        _conf.setIncludedClassPath(false);
        _conf.setPluginEventListener(new DefaultPluginEventListener());

    Create and initialize the plug-in factory instance object:

        IPluginFactory _factory = new DefaultPluginFactory();
        _factory.init(_conf);

    Customize the event listening method of the plug-in factory:

    The event processing method of the custom plug-in factory is different from the default plug-in factory. The plug-in life cycle event monitoring must be completed by implementing the IPluginEventListener interface. The IPluginEventListener interface event method and description are as follows:

    Sample code:

    public class DemoPluginEventListener implements IPluginEventListener {
    
        public void onInited(IPluginContext context, IPlugin plugin) {
            System.out.println("onInited: " + context.getPluginMeta().getName());
        }
    
        public void onStarted(IPluginContext context, IPlugin plugin) {
            System.out.println("onStarted: " + context.getPluginMeta().getName());
        }
    
        public void onShutdown(IPluginContext context, IPlugin plugin) {
            System.out.println("onShutdown: " + context.getPluginMeta().getName());
        }
    
        public void onDestroy(IPluginContext context, IPlugin plugin) {
            System.out.println("onDestroy: " + context.getPluginMeta().getName());
        }
    }
