无法为事务打开Hibernate Session：org.hibernate.exception.GenericJDBCException

时间：2017-02-02 06:47:18

标签： spring hibernate database-connection sessionfactory

我有一个spring项目，我使用mysql作为数据库。我在servelet配置文件中配置了Tomcat JDBC连接池，连接在我的本地机器上工作正常。但最近我重新创建了我们的远程服务器我在尝试访问数据库时遇到以下错误。

{"error":"unauthorized","error_description":"Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Could not open connection"}curl: (6) Could not resolve host: application

那么这个错误的原因是什么。同样的项目之前没有问题，重新启动服务器后出现问题。我可以使用相同的用户名和密码从phpmyadmin访问远程服务器mysql数据库。也没问题我们在本地机器和本地mysql数据库中运行该项目。 下面是我的spring servlet配置文件。

这就是我在服务类中使用会话的方式：

    @Repository
@Transactional
public class MyMainService implements MainDao {
    @Autowired
    private SessionFactory sessionFactory;

    private org.hibernate.Session getCurrentSession(){
        return sessionFactory.getCurrentSession();
    }

    // just a sample
    @Override
    public void setUser(String idStr, Integer age) {
        UserSample newUserSam = new UserSample();
        try{
            newUserSam.setAge(age);
            newUserSam.setId(idStr);
            getCurrentSession().saveOrUpdate(newUserSam);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

在pom.xml中添加以下依赖项

            <artifactId>slf4j-log4j12</artifactId>
            <version>1.6.4</version>
        </dependency>

这是我的pom.xml，它可以很好地与JBoss一起使用。只需确保你有其他 HIBERNATE 依赖关系，其余部分保持不变。
