Export entities to database schema through java code - spring

Question

A long time ago, I did that with a code like that:
Configuration config = new Configuration();
Properties props = new Properties();
FileInputStream fos = = new FileInputStream( file_name );
props.load(fos);
fos.close();
config.setProperties(props);
config.addAnnotatedClass(...);
Connection conn = DriverManager.getConnection(url,usuario,senha);
SchemaExport schema = new SchemaExport();
schema.create(true, true);
But now, if I try use this code, I got a compilation error. Seeing the javadoc for SchemaExport, I notice a lot of changes in the methods used on this example.
Hpw I could do that now?
update
based on the suggested link, I implemented the method this way:
public void criarTabelas(String server, String user, String pass) throws Exception {
StandardServiceRegistry standardRegistry = new StandardServiceRegistryBuilder().applySetting("hibernate.hbm2ddl.auto", "create").applySetting("hibernate.dialect", dialect).applySetting("hibernate.id.new_generator_mappings", "true").build();
MetadataSources sources = new MetadataSources(standardRegistry);
for(Class<?> entity : lista_entidades())
sources.addAnnotatedClass(entity);
MetadataImplementor metadata = (MetadataImplementor) sources.getMetadataBuilder().build();
SchemaExport export = new SchemaExport();
export.create(EnumSet.of(TargetType.DATABASE), metadata);
}
private List<Class<?>> lista_entidades() throws Exception {
List<Class<?>> lista = new ArrayList<Class<?>>();
ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(false);
scanner.addIncludeFilter(new AnnotationTypeFilter(Entity.class));
for (BeanDefinition bd : scanner.findCandidateComponents("org.loja.model"))
lista.add(Class.forName(bd.getBeanClassName()));
return lista;
}
Now I need a way to establish a jdbc connection and associate to the SchemaExport.

I solve this issue with this code:
public void criarTabelas(String server, String user, String pass) throws Exception {
Connection conn = DriverManager.getConnection(url_prefix+server+"/"+url_suffix, user, pass);
StandardServiceRegistry standardRegistry = new StandardServiceRegistryBuilder()
.applySetting("hibernate.hbm2ddl.auto", "create")
.applySetting("hibernate.dialect", dialect)
.applySetting("hibernate.id.new_generator_mappings", "true")
.applySetting("javax.persistence.schema-generation-connection", conn)
.build();
MetadataSources sources = new MetadataSources(standardRegistry);
for(Class<?> entity : lista_entidades())
sources.addAnnotatedClass(entity);
MetadataImplementor metadata = (MetadataImplementor) sources.getMetadataBuilder().build();
SchemaExport export = new SchemaExport();
export.create(EnumSet.of(TargetType.DATABASE), metadata);
conn.close();
}
private List<Class<?>> lista_entidades() throws Exception {
List<Class<?>> lista = new ArrayList<Class<?>>();
ClassPathScanningCandidateComponentProvider scanner = new ClassPathScanningCandidateComponentProvider(false);
scanner.addIncludeFilter(new AnnotationTypeFilter(Entity.class));
for (BeanDefinition bd : scanner.findCandidateComponents("org.loja.model"))
lista.add(Class.forName(bd.getBeanClassName()));
System.out.println("lista: "+lista);
return lista;
}
