Spring Framework使用JNDI API。由於它只是一個API，而不是一個實現，所以您需要告訴它要使用哪個JNDI實現。您可以使用Spring的JNDITemplate並通過屬性文件包括java.naming.factory.initial這正是這個錯誤跟蹤是突出

可以實現，像下面的例子中使用基於註解Spring配置傳遞所需的參數。

@Bean 
DataSource dataSource() { 
    DataSource dataSource = null; 
    JndiTemplate jndi = new JndiTemplate(); 
    try { 
      dataSource = (DataSource) jndi.lookup("java:comp/env/jdbc/jndiName"); 
     } catch (NamingException e) { 
      logger.error("NamingException for java:comp/env/jdbc/jndiName", e); 
     } 
     return dataSource; 
    }
