Hibernate獲取配置元信息的方法合集

1、

ClassMetadata classMetadata = sessionFactory.getClassMetadata(AppTaskConfig.class);
String[] propertyNames = classMetadata.getPropertyNames();

for (String property : propertyNames) {
    Configuration configuration = sessionFactoryBean.getConfiguration();
    PersistentClass persistentClass = configuration
                    .getClassMapping(Details.class.getName());
    String columnName = ((Column) persistentClass.getProperty(property)
                    .getColumnIterator().next()).getName();
}

2、

Configuration configuration = new Configuration();
configuration.configure("hibernate.cfg.xml");
SessionFactory sessionFactory = configuration.buildSessionFactory();

// Way1 - get the all Class Mapping Information using Configuration
Iterator<PersistentClass> classMappings = configuration.getClassMappings();
while(classMappings.hasNext()) {
PersistentClass persistentClass = classMappings.next();
Table table = persistentClass.getTable();
String tableName = table.getName();
System.out.println(tableName);
}

// Way2 - get the all Class Metadata Information using SessionFactory
Map<String, ClassMetadata> classMetaDataMap = sessionFactory.getAllClassMetadata();
for(Map.Entry<String, ClassMetadata> metaDataMap : classMetaDataMap.entrySet()) {
ClassMetadata classMetadata = metaDataMap.getValue();
AbstractEntityPersister abstractEntityPersister = (AbstractEntityPersister) classMetadata;
String tableName = abstractEntityPersister.getTableName();
System.out.println(tableName);
}

// Way3 - using Session 
SessionImpl sessionImpl = (SessionImpl) sessionFactory.openSession();
try {
Connection connection = sessionImpl.connection();
DatabaseMetaData databaseMetaData = connection.getMetaData();
ResultSet resultSet = databaseMetaData.getTables(null, null, null, new String[] {"TABLE"});
while(resultSet.next()) {
String tableName = resultSet.getString(3);
System.out.println(tableName);
}
} catch (Exception e) {
e.printStackTrace();
