Hibernate urgente - gerar Tabelas

Assuntos Gerais
#1

Pessoal, configurei tudo certinho no habernate e no eclipse.
Quando rodo o método para gerar tabelas, ele me da as segintes linhas e não gera as tabelas:

new SchemaExport(cfg).create(true, true);O primeiro parâmetro é para gerar o script, o segundo para exportá-lo para o banco, e por estar false, não gerava o banco. Tente assim que deve funcionar.

Flw! :thumbup:

Coloquei os dois parametros como True e agora a mensagem aumentou mais ainda naõ gerou a tabela de produtos:

coloca no arqivo de hibernate.properties a propriedade: hibernate.hbm2ddl.auto create e da uma testada.

Outra coisa, abaixo do @Entity, acho que tem que colocar @Table(name = "Produtos")

#5

Nada ainda, o Show_SQL está como true e não mostra nenhum SQL.
Realmente ele não está criando a tabela.

Por favor, continuem me ajudando. Estou desesperado.

Abraços!

##############################

Proxool Connection Pool###

##############################

Properties for external configuration of Proxool

hibernate.proxool.pool_alias pool1

Only need one of the following

#hibernate.proxool.existing_pool true
#hibernate.proxool.xml proxool.xml
#hibernate.proxool.properties proxool.properties

#################################

Plugin ConnectionProvider

#################################

use a custom ConnectionProvider (if not set, Hibernate will choose a built-in ConnectionProvider using hueristics)

#hibernate.connection.provider_class org.hibernate.connection.DriverManagerConnectionProvider
#hibernate.connection.provider_class org.hibernate.connection.DatasourceConnectionProvider
#hibernate.connection.provider_class org.hibernate.connection.C3P0ConnectionProvider
#hibernate.connection.provider_class org.hibernate.connection.ProxoolConnectionProvider

#######################

Transaction API

#######################

Enable automatic flush during the JTA beforeCompletion() callback

(This setting is relevant with or without the Transaction API)

#hibernate.transaction.flush_before_completion

Enable automatic session close at the end of transaction

(This setting is relevant with or without the Transaction API)

#hibernate.transaction.auto_close_session

the Transaction API abstracts application code from the underlying JTA or JDBC transactions

#hibernate.transaction.factory_class org.hibernate.transaction.JTATransactionFactory
#hibernate.transaction.factory_class org.hibernate.transaction.JDBCTransactionFactory

to use JTATransactionFactory, Hibernate must be able to locate the UserTransaction in JNDI

default is java:comp/UserTransaction

you do NOT need this setting if you specify hibernate.transaction.manager_lookup_class

#jta.UserTransaction jta/usertransaction
#jta.UserTransaction javax.transaction.UserTransaction
#jta.UserTransaction UserTransaction

to use the second-level cache with JTA, Hibernate must be able to obtain the JTA TransactionManager

#hibernate.transaction.manager_lookup_class org.hibernate.transaction.JBossTransactionManagerLookup
#hibernate.transaction.manager_lookup_class org.hibernate.transaction.WeblogicTransactionManagerLookup
#hibernate.transaction.manager_lookup_class org.hibernate.transaction.WebSphereTransactionManagerLookup
#hibernate.transaction.manager_lookup_class org.hibernate.transaction.OrionTransactionManagerLookup
#hibernate.transaction.manager_lookup_class org.hibernate.transaction.ResinTransactionManagerLookup

##############################

Miscellaneous Settings

##############################

print all generated SQL to the console

hibernate.show_sql true

format SQL in log and console

hibernate.format_sql true

add comments to the generated SQL

#hibernate.use_sql_comments true

generate statistics

#hibernate.generate_statistics true

auto schema export

#hibernate.hbm2ddl.auto create-drop
hibernate.hbm2ddl.auto create
#hibernate.hbm2ddl.auto update
#hibernate.hbm2ddl.auto validate

specify a default schema and catalog for unqualified tablenames

#hibernate.default_schema test
#hibernate.default_catalog test

enable ordering of SQL UPDATEs by primary key

#hibernate.order_updates true

set the maximum depth of the outer join fetch tree

hibernate.max_fetch_depth 1

set the default batch size for batch fetching

#hibernate.default_batch_fetch_size 8

rollback generated identifier values of deleted entities to default values

#hibernate.use_identifer_rollback true

enable bytecode reflection optimizer (disabled by default)

#hibernate.bytecode.use_reflection_optimizer true

#####################

JDBC Settings

#####################

specify a JDBC isolation level

#hibernate.connection.isolation 4

enable JDBC autocommit (not recommended!)

#hibernate.connection.autocommit true

set the JDBC fetch size

#hibernate.jdbc.fetch_size 25

set the maximum JDBC 2 batch size (a nonzero value enables batching)

#hibernate.jdbc.batch_size 5
#hibernate.jdbc.batch_size 0

enable batch updates even for versioned data

hibernate.jdbc.batch_versioned_data true

enable use of JDBC 2 scrollable ResultSets (specifying a Dialect will cause Hibernate to use a sensible default)

#hibernate.jdbc.use_scrollable_resultset true

use streams when writing binary types to / from JDBC

hibernate.jdbc.use_streams_for_binary true

use JDBC 3 PreparedStatement.getGeneratedKeys() to get the identifier of an inserted row

#hibernate.jdbc.use_get_generated_keys false

choose a custom JDBC batcher

hibernate.jdbc.factory_class

enable JDBC result set column alias caching

(minor performance enhancement for broken JDBC drivers)

hibernate.jdbc.wrap_result_sets

choose a custom SQL exception converter

#hibernate.jdbc.sql_exception_converter

##########################

Second-level Cache

##########################

optimize chache for minimal “puts” instead of minimal “gets” (good for clustered cache)

#hibernate.cache.use_minimal_puts true

set a prefix for cache region names

hibernate.cache.region_prefix hibernate.test

disable the second-level cache

#hibernate.cache.use_second_level_cache false

enable the query cache

#hibernate.cache.use_query_cache true

store the second-level cache entries in a more human-friendly format

#hibernate.cache.use_structured_entries true

choose a cache implementation

#hibernate.cache.provider_class org.hibernate.cache.EhCacheProvider
#hibernate.cache.provider_class org.hibernate.cache.EmptyCacheProvider
hibernate.cache.provider_class org.hibernate.cache.HashtableCacheProvider
#hibernate.cache.provider_class org.hibernate.cache.TreeCacheProvider
#hibernate.cache.provider_class org.hibernate.cache.OSCacheProvider
#hibernate.cache.provider_class org.hibernate.cache.SwarmCacheProvider

choose a custom query cache implementation

#hibernate.cache.query_cache_factory

############

JNDI

############

specify a JNDI name for the SessionFactory

#hibernate.session_factory_name hibernate/session_factory

Hibernate uses JNDI to bind a name to a SessionFactory and to look up the JTA UserTransaction;

if hibernate.jndi.* are not specified, Hibernate will use the default InitialContext() which

is the best approach in an application server

#file system
#hibernate.jndi.class com.sun.jndi.fscontext.RefFSContextFactory
#hibernate.jndi.url file:/

#WebSphere
#hibernate.jndi.class com.ibm.websphere.naming.WsnInitialContextFactory
#hibernate.jndi.url iiop://localhost:900/

[/code]

Achei o problema:

import org.hibernate.annotations.Entity; Você deve usar o @Entity da JPA, não o do Hibernate.

import javax.persistence.Entity;Isso vai resolver.

Flw! :thumbup:

#8

Cara era isso mesmo,
Agora me diga mais uma coisa,

Criei a tabela, e agora ela tem dados.
Gostaria de alterar a classe mudando o preço do produto de double pra String. Como refletir isso no banco de dados sem dar rop na tabela?

No mais muito obrigado pelas dicas, te devo essa!

Abraços!

#9

Inclua no seu hibernate.properties a linha:

hibernate.hbm2ddl.auto updateAssim ele valida o que tem na base em relação aos mapeamentos quando a SessionFactory é criada. Mas não estou certo se ele vai atualizar a coluna se já existirem valores nela. E teste primeiro antes de fazer no banco de produção! :mrgreen:

Blz? Flw! :thumbup:
