使用Hibernate 4生成SQL DB创建脚本

您可以直接使用SchemaExport类生成DDL脚本：

对于Hibernate 4：

    Configuration config = new Configuration();    Properties properties = new Properties();    properties.put("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");    properties.put("hibernate.connection.url", "jdbc:postgresql://localhost:5432/Test");     properties.put("hibernate.connection.username", "username");    properties.put("hibernate.connection.password", "password");    properties.put("hibernate.connection.driver_class", "org.postgresql.Driver");    properties.put("hibernate.show_sql", "true");    config.setProperties(properties);    config.addAnnotatedClass(MyMappedPojo1.class);    config.addAnnotatedClass(MyMappedPojo2.class);    ..................    SchemaExport schemaExport = new SchemaExport(config);    schemaExport.setDelimiter(";");        schemaExport.create(true, false);

Hibernate 5的更新：

    Properties properties = new Properties();    properties.put("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");    properties.put("hibernate.connection.url", "jdbc:postgresql://localhost:5432/Test");     properties.put("hibernate.connection.username", "username");    properties.put("hibernate.connection.password", "password");    properties.put("hibernate.connection.driver_class", "org.postgresql.Driver");    properties.put("hibernate.show_sql", "true");    StandardServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()     .applySettings(properties).build();    metadataSources metadataSource = new metadataSources(serviceRegistry);    metadataSource.addAnnotatedClass(MyMappedPojo1.class);    metadataSource.addAnnotatedClass(MyMappedPojo2.class);    ...........    metadata meta = metadataSource.buildmetadata();    SchemaExport schemaExport = new SchemaExport();    schemaExport.setDelimiter(";");    schemaExport.execute(EnumSet.of(TargetType.STDOUT), Action.CREATE, meta);
