SchemaExport不要在數據庫中創建我的表

[英]SchemaExport don't create my tables in the database

問題描述

我最近在我的spring項目中添加了關注服務類，該類具有創建供應用程序使用的數據庫AND表的功能： 

@Service
public class InstallService {

    @Autowired
    UsuarioHome usuario;

    @Autowired
    AutorizacaoHome autorizacao;

    public boolean create_database(String maquina, String usuario, String senha) {
        try {
            Class.forName("org.postgresql.Driver");
            String url = "jdbc:postgresql://localhost:5432/postgres?user="+usuario+"&password="+senha;
            Connection conn = null;
            conn = DriverManager.getConnection(url);
            Statement stmt = conn.createStatement();
            String sql = "SELECT * FROM pg_database";
            ResultSet rs = stmt.executeQuery(sql);
            while(rs.next()) {
                if(rs.getString("datname").equals("horario"))
                    return false;
            }
            sql = "CREATE DATABASE horario WITH OWNER = "+usuario+" ENCODING = 'UTF8' TABLESPACE = pg_default LC_COLLATE = 'pt_BR.utf8' LC_CTYPE = 'pt_BR.utf8' CONNECTION LIMIT = -1;";
            stmt.executeUpdate(sql);
            rs.close();
            stmt.close();
            conn.close();
        } catch (SQLException e) {
            e.getStackTrace();
        } catch (ClassNotFoundException e) {
            e.getStackTrace();
        }

        return create_tables(maquina, usuario, senha);
    }

    public boolean create_tables(String maquina, String usuario, String senha) {
        Configuration config = new Configuration();
        config.setProperty("jdbc.Classname", "org.postgresql.Driver");
        config.setProperty("jdbc.url", "jdbc:postgresql://"+maquina+"/horario?charSet=LATIN1");
        config.setProperty("jdbc.user", usuario);
        config.setProperty("jdbc.pass", senha);
        config.setProperty("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
        config.setProperty("hibernate.show_sql", "false");
        config.setProperty("hibernate.hbm2ddl.auto", "create");

        SchemaExport schema = new SchemaExport(config);
        schema.create(true, true);

        Properties properties = new Properties();
        properties.setProperty("jdbc.Classname", "org.postgresql.Driver");
        properties.setProperty("jdbc.url", "jdbc:postgresql://"+maquina+"/horario?charSet=LATIN1");
        properties.setProperty("jdbc.user", usuario);
        properties.setProperty("jdbc.pass", senha);
        properties.setProperty("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
        properties.setProperty("hibernate.show_sql", "false");
        properties.setProperty("hibernate.hbm2ddl.auto", "validate");

        try {
            File file = new File("database.properties");
            FileOutputStream fileOut = new FileOutputStream(file);
            properties.store(fileOut, "propriedades");
            fileOut.close();
        } catch(FileNotFoundException e) {
            e.printStackTrace();
        } catch(IOException e) {
            e.printStackTrace();
        }

        return autorizacao.persist(new Autorizacao("permissao_teste"));
    }

    public boolean create_user(String login, String senha, String pnome, String unome) {
        Usuario novo = new Usuario(login, senha, pnome, unome);
        novo.setAutorizacao(autorizacao.findALL());
        return usuario.persist(novo);
    }
}

當我運行應用程序並調用方法create_database時，會發生此錯誤：

有人知道如何解決嗎？

當執行create_tables方法時，我沒有收到任何錯誤，但是在數據庫中沒有創建任何表，因此當我嘗試在表中插入數據時導致錯誤。

誰能告訴我怎么了？ 我現在什么都看不到。

@kleber mota似乎是從日志文件內容org.hibernate.tool.hbm2ddl.SchemaExport執行創建了該模式。無法連接。 使用postgres sql檢查架構是否以root / admin身份創建。

好的，我終於完成了目標，現在正在創建數據庫和表。 方法create_table（0的最終代碼為： 

public void create_tables(String maquina, String usuario, String senha) {
    System.out.println("create_tables");
    create_properties(maquina, usuario, senha);

    Configuration config = new Configuration();
    Properties props = new Properties();
    FileInputStream fos;
    try {
        fos = new FileInputStream( "database.properties" );
        props.load(fos);
        fos.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    config.setProperties(props);

    config.addAnnotatedClass(com.horariolivre.entity.Atributo.class);
    config.addAnnotatedClass(com.horariolivre.entity.ConfigHorarioLivre.class);
    config.addAnnotatedClass(com.horariolivre.entity.Evento.class);
    config.addAnnotatedClass(com.horariolivre.entity.HorarioLivre.class);
    config.addAnnotatedClass(com.horariolivre.entity.Key.class);
    config.addAnnotatedClass(com.horariolivre.entity.Tipo.class);
    config.addAnnotatedClass(com.horariolivre.entity.Value.class);
    config.addAnnotatedClass(com.horariolivre.entity.Autorizacao.class);
    config.addAnnotatedClass(com.horariolivre.entity.Usuario.class);

    try {
        String url = props.getProperty("jdbc.url");
        Connection conn = DriverManager.getConnection(url,usuario,senha);
        SchemaExport schema = new SchemaExport(config, conn);
        schema.create(true, true);
    } catch (SQLException e) {
        e.printStackTrace();
    }

    insert_default_values();
}

基本上，我在方法中包括以下幾行指令： 

config.addAnnotatedClass(com.horariolivre.entity.Atributo.class);

我告訴程序應該在數據庫中創建哪些實體類。 做到了。
