我最近将以下服务类添加到我的spring项目中，该项目具有为应用程序使用创建数据库和表的功能：
@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);
}
}
当我运行应用程序并调用方法create_database时，会发生以下错误：

执行create_tables方法时没有收到任何错误，但是在数据库中没有创建表，当我尝试在表中插入数据时导致错误。
任何人都可以告诉我什么是错的？我现在什么都看不到。
答案 0 :(得分：0)
@kleber mota似乎从日志文件内容org.hibernate.tool.hbm2ddl.SchemaExport execute创建了模式 信息：HHH000230：架构导出完成，我想因为没有提供给该用户的访问权限或授权或特权，所以hibernate无法连接。使用postgres sql检查架构是否创建为root / admin。
答案 1 :(得分：0)
好的，我终于完成了我的目标，现在正在创建数据库和表。方法create_table的最终代码（0是：
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，我在方法中包含一组带有指令的行：
config.addAnnotatedClass(com.horariolivre.entity.Atributo.class);
我告诉编程应该在数据库中创建哪些实体类。这样做。
