无法打开JPA EntityManager进行事务处理; org.hibernate.exception.GenericJDBCException：无法打开连接

我正在使用jpa规范的spring hibernate，当我的web应用程序尝试连接到数据库时，它给出了上述异常。java.sql.SQLException：访问被用户拒绝'sandip'@'localhost'（使用密码：YES），sandip是我的linux用户。无法打开JPA EntityManager进行事务处理; org.hibernate.exception.GenericJDBCException：无法打开连接

数据源集就像.......

@Bean 
public DataSource getDataSource() {  
DriverManagerDataSource ds = new DriverManagerDataSource(
      env.getProperty("url")); 
    ds.setDriverClassName(env.getProperty("driver")); 
    ds.setUsername(env.getProperty("user")); 
    ds.setPassword(env.getProperty("pass"));

//设置JPA和transactionManager的

@Bean 
public LocalContainerEntityManagerFactoryBean entityManagerFactory() { 
    LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean(); 
    emf.setDataSource(getDataSource()); 
    emf.setPackagesToScan("com.genesis.model"); 
    emf.getJpaPropertyMap().put("hibernate.dialect", 
      env.getProperty("hibernate.dialect")); 
    HibernateJpaVendorAdapter va = new HibernateJpaVendorAdapter(); 
    emf.setJpaVendorAdapter(va); 
    return emf; 
}

属性文件.........

driver=com.mysql.jdbc.Driver 
url=jdbc:mysql://localhost:3306/test 
hibernate.dialect=org.hibernate.dialect.MySQLDialect 
user=root 
pass=sandy1234

控制台输出。

以及例外是非常明确的，你的用户/通过没有访问连接到数据库测试localhost –

但我可以从终端使用以下命令访问mysql -uroot -psandy1234 –

它看起来像你的代码没有正确地拾取属性。异常告诉你它试图连接成'sandip'，但它应该根据属性连接为'root'。你的代码是否被调用？您可以提供的任何调试信息？ – Rubrick

我做了一些调试来解决，我需要用下面的代码

@Bean 
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() { 
     LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean(); 
     entityManagerFactoryBean.setDataSource(getDataSource()); 
     entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistence.class); 
     entityManagerFactoryBean.setPackagesToScan(env.getRequiredProperty(PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN)); 

     entityManagerFactoryBean.setJpaProperties(hibProperties()); 

     return entityManagerFactoryBean; 
    } 

    private Properties hibProperties() { 
     Properties properties = new Properties(); 
     properties.put(PROPERTY_NAME_HIBERNATE_DIALECT, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT)); 
     properties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL)); 
     return properties; 
    }

更换的entityManagerFactory（）豆，但我需要澄清HibernatePersistence类现在已废弃所以这可能是这个实现的替代
