Dynamic access to alfresco-global.properties

Question

I can't access to alfresco-global.properties values dynamically although I read this post: Accessing values from Alfresco's alfresco-global.properties file

Here is my conf:

service-context.xml

<bean id="AccesGlobalPropertiesService" class="com.package.ksc.services.AccesGlobalPropertiesService">
     <property name="properties">
        <ref bean="global-properties"/>
    </property>
</bean>

AccesGlobalPropertiesService.java

import org.springframework.stereotype.Service;
import java.util.Properties;

@Service
public class AccesGlobalPropertiesService {

    public Properties properties;

    public void setProperties(Properties properties) {
        this.properties = properties;
    }
    public Properties getProperties() {
        return properties;
    }
}

Worker.java

public abstract class ClassifierServiceCommon {

   private AccesGlobalProperties accesGlobalProperties;
   private Properties properties;    

   /* Constructor */
   protected Worker(accesGlobalProperties) {
     this.accesGlobalProperties= accesGlobalProperties;
   }

   ...

   protected Boolean propAcces() {
      accesGlobalProperties.properties.getProperty("myPropKey");
      ...
   }
}

I get a NullPointerException when I call getProperty("myPropKey") ...

What's wrong please? Thanks

have you inject AccesGlobalProperties properly? can you add snippet of your context file — Abbas Kararawala, Oct 07 '19 at 09:34

It seems like you made the mistake of defining two beans with different ID-s:

One bean comes from the XML, its ID is explicitly specified as "AccesGlobalPropertiesService". Its properties field is correctly set.
The other bean comes from Spring component scanning (thanks to the @Service annotation), its ID is implicitly set to "accesGlobalPropertiesService". Its properties field is not set, because a @Resource or @Autowired annotation is missing for that field (see e. g. this question on how to use them).

And then you most probably use the second (incomplete) one from your ClassifierServiceCommon class. (You didn't specify how you get the bean there.)

You have to initialize the variable (You don't seem to do it). You need to setProperty() before you getProperty(). As long as you don't initialize properties in the AccesGlobalPropertiesService class, your getProperty() will return null.

I don't know if that's what you're trying to do here :

protected Boolean propAcces(){

  accesGlobalProperties.properties.getProperty("myPropKey");
  ...
}

If that is the case, you should change getProperty for setProperty.

I hope this helps you :)
