I was looking at this wonderful mybatis example
http://mybatis.co.uk/index.php/2010/09/mybatis-simple-and-complete-example.html
that uses mostly annotations but was hoping for an #MyBatisDao annotation so I don't need to ever go back to some mapping file and add a line for each dao that I add to the system. I obviously will just use mapping for now but was just curious if there was a way???
You can use the package element to let it scan for your mappers (since 3.1)

I'm using Lombok in a Spring Boot application, The MongoDB object are the same as my domain model so when I do the mapping I have to specify all the field names even they are the same
public static Receipt toModel(MGReceipt mgReceipt) {
return Receipt.builder()
.id(mgReceipt.getId())
.date(mgReceipt.getDate())
.dueDate(mgReceipt.getDueDate())
...
.build();
}
Is there a way to simplfy this , and avoid to specify all the properties names from MGReceipt that match Receipt ones, with Lombok ? or maybe I should use another solution for the mapping like mapstruct
That's exactly what MapStruct was created for. MapStruct also plays quite nicely with lombok, as described here. Also lombok's #Builder is supported, if you want that.
Make sure you use recent versions of both lombok and MapStruct, and don't forget to add the lombok-mapstruct-binding as a third annotation processor to make sure MapStruct can see everything that lombok generates.
I'm not aware of any easier/nicer framework to do such a mapping. There's also no nice way of doing it manually, as that would require some nasty reflection stuff to identify similarly named fields/getters/setters.
I'm trying to create a custom annotation processor that generates code at compilation time (as hibernate-jpamodelgen does). I've looked in the web, and I find custom annotation processors that works with maven, but do nothing when added to the Annotation Processing > Factory Path option. How could I create a processor compatible in this way? I have not found a tutorial that works.
My idea is to, for example, annotate an entity to generate automatically a base DTO, a base mapper, etc that can be extended to use in the final code.
Thank you all
OK, Already found out the problem. The tutorial I hda found out dint't specified that, in order to the compiler to be able to apply the annotation processor, there must be a META-INF/services/javax.annotation.processing.Processor file that contains the qualified class name of the processor (or processors).
I created the file pointing to my processor class, generated the jar and added it to Annotation Processing > Factory Path and all worked correctly.
Just be careful to keep the order of the processors correctly (for example, hibernate model generator claims the classes, so no more generation will be made after it), and change the jar file name each time you want to replace the library (it seems eclipse keeps a cache). These two things have given me a good headache.
Thanks all
My name is Denis and I really need your help or advice or anything :)
I am developing my project in Zend Framework 1.11 and am using Doctrine 2.1.
I have successfully integrated Doctrine in my ZF project and everything works. I also integrated Gedmo extensions and some my custom extensions.
The problem is with validation. I want to have validation of doctrine entities by using annotations. Because I sometimes need to validate my entities sometimes don't, I want that sort of validation, for example:
$user = new Entity\User; $user->setName('user'); $user->validate();
I don't want to change doctrine generated entities at all, so I won't change setters or use doctrine events for this.#HasLifecycleCallbacks.
I run into example at http://www.spiffyjr.me/2011/07/15/more-doctrine-2-and-zend-framework-integration-goodies/.
I downloaded code but didn't managed to put it in work. I followed instructions from that page, made my entities extend AbstractEntity, but when try to use for example isValid() i recieve following error:
[Semantical Error] The annotation "#Column" in property Bild\Entity\TestTest::$id was never imported. Did you maybe forget to add a "use" statement for this annotation?
I use doctrine annotations without #ORM\, just #, (for example #Column, not #ORM\Column). I even tried to add ORM but no luck it continues to throw errors.
I can recieve metadata for my entity, get field mappings and associating mappings, but when I try to getPropertyAnnotation
// validator annotations
$vAnnotations = self::_getPropertyAnnotation($property, self::ZENDVALIDATION);
var_dump($vAnnotations);die;
I recieve mentioned semantic error.
I tracked the errors down to Doctrine\Common\Annotations\AnnotationReader::getPropertyAnnotations($property); not returning annotations but throwing errors.
What do you think it can be?
It seems like I am not doing something properly but can't figure out what.
So, I need to make abstract entity, make my entities extend it, and make functions to validate my entities by using annotations.
So please, help me with this, if you can. I really need for my project but couldn't find a solution.
Thanks in advance.
Best regards.
The problem is caused by the configuration of the annotation reader. I went through the same problems while integrating the Symfony2 validator service for my Doctrine2 models in ZF1, more on the blog post here http://ssmusoke.wordpress.com/2012/03/04/doctrine-2-day-2-model-validation-using-symfony-validator-service-in-zend-framework/
I am using Dozer to map my JAXB objects that come off a WebService interface to my domain objects. One of the elements or properties in my JAXB is a String set/setLocation(). This would be the description of the location. What I need in the backend is the to take that String and map it to a code which will be stored in my database. I've looked in the Dozer website and junit tests and I don't see anything that I can use as an example. I was hoping I could create some custom setter mapper to do this but I am looking for an example that I can start with. Any help would be appreciated.
With a little investigation I found a way to resolve my problem with a field level converter.
Here is the Dozer documentation for those interested: http://dozer.sourceforge.net/documentation/customconverter.html
I'm trying to work through groovy's Implementing Local AST Transformations tutorial, but whenever I clean my project I get this error in each file that has the #WithLogging annotation in it:
Groovy:Could not find class for Transformation Processor AC.LoggingASTTransformation declared by AC.WithLogging
So you have a package named "AC" that contains both "WithLogging.groovy" and "LoggingASTTransformation.groovy" classes? Does it also contain any classes that implement the "WithLogging" interface?
If so, I'd suggest you move the class(es) that use your annotation to a location outside of the annotation defining package (the default will suffice, for diagnostic purposes) - Order of compilation matters with transformations. See this post on the groovy users mailing list for more on that.
Also try changing the annotation from #WithLogging to #AC.WithLogging.
As far as cleaning with Eclipse is concerned, I had a similar issue and found that I had to make a trivial modification after a clean to any file that contained my annotation. IE, add a space somewhere. Then save the file. This should rebuild everything properly.
