Creating custom maintenance task that is configurable

[royteeuwen]

Hey all,

I have created a custom maintenance task by using the following class. I can add the task in the maintenance page, but the "configure" icon is missing. It only shows the start icon. Any clue on what I am missing?

Thanks!

Roy

@Component( property = { MaintenanceConstants.PROPERTY_TASK_NAME + "=" + "FullIndexerTask", MaintenanceConstants.PROPERTY_TASK_TITLE + "=" + "Full Indexer", JobExecutor.PROPERTY_TOPICS + "=" + MaintenanceConstants.TASK_TOPIC_PREFIX + "FullIndexerTask" } ) @Designate(ocd = FullIndexer.Config.class) public class FullIndexer implements JobExecutor { private static final Logger LOG = LoggerFactory.getLogger(FullIndexer.class); private static final String SUBSERVICE_NAME = "fullindexer"; @ObjectClassDefinition(name = "Full Indexer Task", description = "Full indexer that will reindex all pages for the included site names") @interface Config { @AttributeDefinition(description = "Site names that should be reindexed") String[] site_names(); } private List<String> siteNames = new ArrayList<>(); @Activate protected void activate(Config config) { if (config.site_names() != null) { this.siteNames = Arrays.asList(config.site_names()); } } @Override public JobExecutionResult process(Job job, JobExecutionContext context) { ... } }

Hi 

Please have a look at this Adobe Helpx article 

Link:- http://www.aemcq5tutorials.com/tutorials/custom-osgi-configuration-aem/

// Create Custom OSGI Configuration in AEM

 In this you will learn 

    How to Set and Get OSGI configuration values using Text Field.

    How to Set and Get OSGI configuration values using Drop Down List.

    How to Set and Get OSGI configuration values using Check Box.

    How to Set and Get OSGI configuration values using Multi Field.

Set and Get OSGI configuration values using Textfield: When user wants to get and set single value in osgi configuration, Text Field is preferred. Setting Values: 1 2 @Property(label="Name of the Author",value = "author") @Property(label="Age of the Author",intValue = 15) Getting Values: 1 2 private static final String AUTHOR_NAME = "author.value"; private static final String AUTHOR_AGE = "author.age"; value: This property indicates default value of the configuration. intValue : If you want to take only integer value ,use this property to set default value.

Note:- @Property annotation helps us to define the properties in felix console.

I hope this would help you.

Hey kautuk,

That is the old way of working, it is outdated, the new way is with OSGi DS annotations.

Does this code work?

Yes of course, if you want I can give you the entire class? This is the new way of adding properties, please read the blog of Carsten Ziegler:
