The Hibernate configuration file must define the entity classes: <mapping class=”annotations.Users”/> Or you must explicitly add the class to the configuration using configuration.addClass(annotations.Users.class) // Read mappings as a application resourceName // addResource is for add hbml.xml files in case of declarative approach configuration.addResource(“myFile.hbm.xml”); // not hibernateAnnotations.cfg.xml
The forward slash is valid as is and does not need further encoding. The only reserved characters are: > < & % For even more XML entities – http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references
You need to implement the __toString() method in your Apw\BlackbullBundle\Entity\CategoriesDescription. You could do: public function __toString() { return $this->name; }
Given the table definition: CREATE TABLE webuser( idwebuser SERIAL PRIMARY KEY, … ) Use the mapping: @Entity @Table(name=”webuser”) class Webuser { @Id @SequenceGenerator(name=”webuser_idwebuser_seq”, sequenceName=”webuser_idwebuser_seq”, allocationSize=1) @GeneratedValue(strategy = GenerationType.SEQUENCE, generator=”webuser_idwebuser_seq”) @Column(name = “idwebuser”, updatable=false) private Integer id; // …. } The naming tablename_columname_seq is the PostgreSQL default sequence naming for SERIAL and I recommend that you … Read more
It requires two steps (second is maybe optional, but I always like clean solution) In Explorer open folder where your project resides. Open packages.config using Notepad. Find and remove the line that mentions corrupted package name. Open folder where your solution resides. Open subfolder “packages”. Find folder with corrupted package and remove it. Note: If … Read more
An empty constructor is needed to create a new instance via reflection by your persistence framework. If you don’t provide any additional constructors with arguments for the class, you don’t need to provide an empty constructor because you get one per default. You can also use the @PersistenceConstructor annotation which looks like following @PersistenceConstructor public … Read more
This behavior is correct, otherwise if you change object one and object two with different values you will have problems when persisting them. What is happening is the call to load object two updates the entity loaded in the first call. They must point to the same object since they ARE the same object. This … Read more
First off, I’m assuming you have read the article “Multithreading and the Entity Framework” on MSDN. Solution #1 is almost certainly the safest from a threading perspective, since you are guaranteeing that only one thread is interacting with the context at any give time. There is nothing inherently wrong with keeping the context around- it … Read more
Not sure you can do it exactly as you want but you can use inheritance to produce the same result. AbsT has all the fields but no @Table annotation Ta and Tb inherit from AbsT and have an @Table annotation each Use @Inheritance(strategy=InheritanceType.TABLE_PER_CLASS) in AbsT. Sample code: @Entity @Inheritance(strategy=InheritanceType.TABLE_PER_CLASS) public class abstract AbsT { @Id … Read more
A class is a template for an object (among other things), and is a very general concept. An entity has more semantic significance and is usually tied to a concept (possibly about a real object for example, an Employee or a Student or a Music Album) and is linked to business logic. Entities are usually … Read more
