Feijão com arroz hibernate com hsql

1º Passo: Adicionando as dependências no pom.xml

<dependencies>

<!-- hibernate -->
		<dependency>
			<groupId>org.hibernate</groupId>
			<artifactId>hibernate-core</artifactId>
			<version>5.2.10.Final</version>
		</dependency>
	
		<!-- hsql -->
		<dependency>
			<groupId>org.hsqldb</groupId>
			<artifactId>hsqldb</artifactId>
			<version>2.3.2</version>
			<scope>runtime</scope>
		</dependency>

	</dependencies>

2º Passo: Adicionando o arquivo persistence.xml

Observação importante, a pasta onde o arquivo deve ser colcado é ../src/main/resources/META-INF/

persistence.xml

<?xml version="1.0" encoding="UTF-8"?>

<persistence 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_2_0.xsd"
	version="2.0">

	<persistence-unit name="projeto">
	
		<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
		   	
		<properties>
            <property name="javax.persistence.jdbc.driver" value="org.hsqldb.jdbcDriver" />
			<property name="javax.persistence.jdbc.url"
				value="jdbc:hsqldb:file:db/projeto;locked=false;shutdown=true" />
			<property name="javax.persistence.jdbc.user" value="sa" />
			<property name="javax.persistence.jdbc.password" value="" />
			
			<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect" />
			<property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider" />
			
			<property name="hibernate.hbm2ddl.auto" value="update" />
			<property name="hibernate.show_sql" value="true" />
			<property name="hibernate.format_sql" value="true" />
			
		</properties>

	</persistence-unit>
	
</persistence>

3º Passo: Criando uma fábrica de conexões

classe EntityFactory

public class EntityFactory {
    
    private static EntityManagerFactory emf = Persistence.createEntityManagerFactory("projeto");
        
    public static EntityManager getEntityManager(){
      return emf.createEntityManager();
    }
           
}

O próximo passo é criar as classes de entidades e seus respectivos Dao’s. Abraço.

não tem uma vídeo aula n? pq depois que fiz esse procedimento aí não não funciona mais nada.

Narclk · Setembro 3, 2017, 4:27pm

Amigo deve ter, tente buscar no google, a configuração acima é pra ser utilizado com o banco de dados HSQLDB, achei que você estava começando um projeto do zero, se você já tem um projeto vinculado há algum banco de dados, e apenas quer adicionar o hibernate, você precisa informar detalhes do projeto.

Cleiton_Conceicao · Setembro 3, 2017, 11:00pm

já olhei todos os tutoriais possíveis e mesmo assim meu projeto não funciona.
apareceu um erro em um dos pacotes, porém não sei onde resolver.segue o print.

Narclk · Setembro 4, 2017, 7:29pm

Coloca o stacktrace do erro por favor.

Cleiton_Conceicao · Setembro 5, 2017, 1:36am

resolvi o erro, porém a aplicação não quer abrir no navegador.
segue print.
