如何使用不同於超級用戶（postgres）的用戶訪問postgresql數據庫？

Question

在我的春天應用程序，我有以下的Hibernate的類來訪問我的PostgreSQL數據庫：

@Configuration 
@EnableTransactionManagement 
@PropertySource({ "classpath:persistence.properties" }) 
@ComponentScan({ "org.webapp.persistence" }) 
public class HibernateConfig { 

    @Autowired 
    private Environment env; 

    @Bean 
    public LocalSessionFactoryBean sessionFactory() { 
     LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean(); 
     sessionFactory.setDataSource(restDataSource()); 
     sessionFactory.setPackagesToScan(new String[] { "org.webapp.persistence.model" }); 
     sessionFactory.setHibernateProperties(hibernateProperties()); 

     return sessionFactory; 
    } 

    @Bean 
    public DataSource restDataSource() { 
     BasicDataSource dataSource = new BasicDataSource(); 
     dataSource.setDriverClassName(env.getProperty("jdbc.driverClassname")); 
     dataSource.setUrl(env.getProperty("jdbc.url")); 
     dataSource.setUsername(env.getProperty("jdbc.user")); 
     dataSource.setPassword(env.getProperty("jdbc.pass")); 

     return dataSource; 
    } 

    @Bean 
    @Autowired 
    public HibernateTransactionManager transactionManager(SessionFactory sessionFactory) { 
     HibernateTransactionManager txManager = new HibernateTransactionManager(); 
     txManager.setSessionFactory(sessionFactory); 

     return txManager; 
    } 

    @Bean 
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation() { 
     return new PersistenceExceptionTranslationPostProcessor(); 
    } 

    Properties hibernateProperties() { 
     return new Properties() { 
     /** 
     * 
     */ 
     private static final long serialVersionUID = 1L; 

     { 
      setProperty("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto")); 
      setProperty("hibernate.dialect", env.getProperty("hibernate.dialect")); 
      setProperty("hibernate.globally_quoted_identifiers", "true"); 
     } 
     }; 
    } 
} 

我persitence.properties文件是：

jdbc.driverClassname=org.postgresql.Driver 
jdbc.url=jdbc:postgresql://localhost:5432/wehavescience?charSet=LATIN1 
jdbc.user=klebermo 
jdbc.pass=123 
hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect 
hibernate.show_sql=true 
hibernate.hbm2ddl.auto=update 

我的數據庫有三個表，它們分別是：

CREATE TABLE usuario 
(
    id serial NOT NULL, 
    login character varying(100), 
    senha character varying(100), 
    CONSTRAINT pf_usuario PRIMARY KEY (id) 
) 
WITH (
    OIDS=FALSE 
); 
ALTER TABLE usuario 
    OWNER TO klebermo; 
GRANT ALL ON TABLE usuario TO klebermo; 
GRANT SELECT ON TABLE usuario TO public; 

表autorizacoes：

CREATE TABLE autorizacao 
(
    id serial NOT NULL, 
    nome character varying(100), 
    CONSTRAINT pf_autorizacao PRIMARY KEY (id) 
) 
WITH (
    OIDS=FALSE 
); 
ALTER TABLE autorizacao 
    OWNER TO klebermo; 
GRANT ALL ON TABLE autorizacao TO klebermo; 
GRANT SELECT ON TABLE autorizacao TO public; 

和表autorizacao_usuario

CREATE TABLE autorizacao_usuario 
(
    id serial NOT NULL, 
    usuario integer, 
    autorizacao integer, 
    CONSTRAINT pf_autorizacao_usuario PRIMARY KEY (id), 
    CONSTRAINT fk_autorizacao FOREIGN KEY (autorizacao) 
     REFERENCES autorizacao (id) MATCH SIMPLE 
     ON UPDATE NO ACTION ON DELETE NO ACTION, 
    CONSTRAINT fk_usuario FOREIGN KEY (usuario) 
     REFERENCES usuario (id) MATCH SIMPLE 
     ON UPDATE NO ACTION ON DELETE NO ACTION 
) 
WITH (
    OIDS=FALSE 
); 
ALTER TABLE autorizacao_usuario 
    OWNER TO klebermo; 
GRANT ALL ON TABLE autorizacao_usuario TO klebermo; 
GRANT SELECT ON TABLE autorizacao_usuario TO public; 

我的問題是，當我運行該項目，數據庫不能被該用戶（僅postgres用戶，誰是管理員用戶）訪問。

如何修改應用程序/數據庫以允許其他用戶訪問表？

Answer 1

您需要create a user爲應用程序和GRANT permissions來連接和訪問表。

我不會推薦你的應用程序使用管理員憑證。
