Gente!!!!
Preciso de um help.
Se puderem me ajudar...
Estou tentando aprender Hibernate, já entendi a Teoria mas estou com duvida na parte prática!!

Nessa parte do código : Persistence.createEntityManagerFactory("Hibernate.cfg.xml");
O que eu tenho que colocar entre parenteses?

Bom, faltava esse arquivo aqui pelo wizard do netbeans :

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt; &lt;persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"&gt; &lt;persistence-unit name="HibernateCRUDPU" transaction-type="RESOURCE_LOCAL"&gt; &lt;provider&gt;org.hibernate.ejb.HibernatePersistence&lt;/provider&gt; &lt;properties&gt; &lt;property name="hibernate.connection.username" value="root"/&gt; &lt;property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/&gt; &lt;property name="hibernate.connection.password" value="admin"/&gt; &lt;property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/mysql?zeroDateTimeBehavior=convertToNull"/&gt; &lt;property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider"/&gt; &lt;property name="hibernate.hbm2ddl.auto" value="create-drop"/&gt; &lt;/properties&gt; &lt;/persistence-unit&gt; &lt;/persistence&gt;

Mas ainda da esse erro:

<blockquote>Exception in thread “main” java.lang.IllegalArgumentException: Unknown entity: Model.Maca

at hibernatecrud.HibernateCRUD.main(HibernateCRUD.java:24)

vc não preciso do hibernate.cfg.xml apenas o persistence.xml que deve ficar na pasta META-INF

no seu codigo

public class HibernateCRUD {  
  
     
    public static void main(String[] args)   
    {  
       Maca maca = new Maca();  
       maca.setCor("Azul");  
       maca.setTamanho(10);  
         
       EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("Hibernate.cfg.xml");  // essa é a forma errada. aqui vc deve passar o persistence unit
       EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("HibernateCRUDPU");  // forma certa.
       EntityManager manager = entityManagerFactory.createEntityManager();  
       manager.getTransaction().begin();  
         
       manager.persist(maca);  
       manager.getTransaction().commit();  
       manager.close();  
       entityManagerFactory.close();  
     
          
          
          
    }  
  
}

O persitence unit fica na no persistence.xml nessa linha

<persistence-unit name="HibernateCRUDPU" transaction-type="RESOURCE_LOCAL">

Sera que é esse transaction-type=“RESOURCE_LOCAL” ?

falta o nome da sua database

<property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306"/>  //falta da nome da database na url

outra coisa como vc esta usando jpa use as property do jpa so use da a do provider se não existir na jpa

outra dica crie uma fabrica de entityManager e instancia a entityManagedFactory apenas uma vez, entityManagedFactory é um recurso caro não deve ser criado em toda chamada de metodo

Criei um novo schema chamado “hibernate”

<?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> <persistence-unit name="HibernateCRUDPU" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> <class>Model.Maca</class> <properties> <property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider"/> <property name="hibernate.connection.username" value="root"/> <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/> <property name="hibernate.connection.password" value="admin"/> <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/hibernate"/> <property name="hibernate.hbm2ddl.auto" value="create-drop"/> </properties> </persistence-unit> </persistence>

Ainda nada :frowning:
