Magnolia Powernode

The PowerNode module provides a special wrapper for JCR nodes with extended functionality.

Advantages:

• Fully compatible to JCR nodes: PowerNode implements the javax.jcr.Node interface
• No checked RepositoryExceptions: all checked exceptions either handled or wrapped in runtime exceptions
• Stream compatible: since there are no checked exceptions, PowerNodes can be easily used in streams
• Blossom compatible: PowerNodes can be injected into Blossom templates

Setup

• Add Maven dependency:

  <dependency>
      <groupId>com.namics.oss.magnolia</groupId>
      <artifactId>magnolia-powernode</artifactId>
      <version>2.0.7</version>
  </dependency>

• Add binding for ZoneId provider

  import info.magnolia.context.MgnlContext;
  import info.magnolia.context.WebContext;
  import info.magnolia.ui.framework.util.TimezoneUtil;
  
  import javax.inject.Inject;
  import javax.inject.Provider;
  import java.time.ZoneId;
  import java.util.Optional;
  
  public class TimeZoneProvider implements Provider<ZoneId> {
  
    @Override
    public ZoneId get() {
        return Optional
                .ofNullable(MgnlContext.getWebContextOrNull())
                .map(WebContext::getUser)
                .map(TimezoneUtil::getUserZoneId)
                .orElseGet(ZoneId::systemDefault);
    }
  }

  <components>
    <id>main</id>
    <component>
      <type>java.time.ZoneId</type>
      <provider>com.namics.engagement.web.configuration.TimeZoneProvider</provider>
    </component>
  </components>

• Import Spring Configuration:

  @Configuration
  @Import({PowerNodeConfiguration.class})
  public class BlossomServletConfiguration {
      //...
  }

• If needed, add the DelegatingPowerNodeArgumentResolver in the BlossomServletConfiguration as follows:

  @Override
  protected void addArgumentResolvers(final List<HandlerMethodArgumentResolver> argumentResolvers) {
        argumentResolvers.add(delegatingPowerNodeArgumentResolverFactory.create(new BlossomHandlerMethodArgumentResolver()));
  }
