Question

其实我是Hibernate中的新手，这是个问题发生错误的配置？

SessionFactory sessionFactory = new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();

我在主类中使用的上述查询也不起作用，但它显示了同样的事情...... ??

Hibernate配置文件

<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
 "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

    </session-factory>
</hibernate-configuration>

我收到以下错误。

在地址实体映射xml文件中，您在表属性之前缺少空格。进行以下更改并尝试：

SELECT *
FROM   countries c
WHERE  c.name LIKE '%$str%' OR
       FIND_IN_SET(c.name, REPLACE($str, ' ', ',')) > 0

到

<class name="com.firoz.Pojo.Address"table="name">
