问题

我是Hibernate的初学者，在创建`SessionFactory`时遇到了问题。

**SessionFactoryProvider.java：**

```java
public class SessionFactoryProvider {

    private static SessionFactory factory;

    public static SessionFactory getFactory() {

        try {
            if (factory == null) {
                Configuration cfg = new Configuration().configure("hibernate.cfg.xml");

                factory = cfg.buildSessionFactory();
            }
        } catch (Exception e) {
            try {
                if (factory == null) {
                    Configuration configuration = new Configuration();
                    // Hibernate设置与hibernate.cfg.xml中的属性等效
                    Properties property = new Properties();
                    property.put(Environment.DRIVER, "com.mysql.jdbc.Driver");
                    property.put(Environment.URL, "jdbc:mysql://localhost:3306/shopingsite");
                    property.put(Environment.USER, "root");
                    property.put(Environment.PASS, "");
                    property.put(Environment.DIALECT, "org.hibernate.dialect.MySQL5Dialect");
                    property.put(Environment.SHOW_SQL, "true");
                    property.put(Environment.HBM2DDL_AUTO, "update");
                    property.put(Environment.POOL_SIZE, 12);
                    configuration.setProperties(property);
                    configuration.addAnnotatedClass(Category.class);
                    configuration.addAnnotatedClass(User.class);
                    configuration.addAnnotatedClass(Product.class);

                    ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder()
                            .applySettings(configuration.getProperties()).build();
                    factory = configuration.buildSessionFactory(serviceRegistry);

                }
            } catch (HibernateException | NullPointerException he) {
                System.out.println("Both factory code Fail");
            }
        }

        return factory;
    }

    public static void shutdow() {
        factory.close();
    }
}

pom.xml：

<!-- 在这里是pom.xml的内容 -->

hibernate.cfg.xml：

<!-- 在这里是hibernate.cfg.xml的内容 -->

日志中显示的错误如下：

Info:   MavenShopping was successfully deployed in 1,530 milliseconds.

How to solve this ?

# 答案1
**得分**: 0

你的[Hibernate SessionFactory][1]存在问题，与你的环境有关。看起来你的编译时库与运行时库不一致，因为在编码时使用的某个类的方法在服务器启动时不存在。

    java.lang.NoSuchMethodError: org.hibernate.internal.CoreMessageLogger.debugf(Ljava/lang/String;I)V

这似乎是导致[SessionFactory创建][2]出现问题的主要原因。

The problem with your [Hibernate SessionFactory][1] has something to do with your environment. It would appear that your compile time libraries are not the same as your runtime libraries, as a method on one of the classes you use when coding isn&#39;t there when the server kicks off.

    java.lang.NoSuchMethodError: org.hibernate.internal.CoreMessageLogger.debugf(Ljava/lang/String;I)V

That seems to be the big problem triggering issues with [SessionFactory creation][2].
