java - 无法创建请求的服务 [org.hibernate.cache.spi.RegionFactory] ​​- Hibernate 4.3.8

Question

我已经开始使用 Hibernate 4.3.8 并尝试使用一个基本程序来插入和检索用户。以下是我的文件。

hibernate .cfg.xml

<?xml version='1.0' encoding='utf-8'?>

<session-factory>

    <!-- Database connection settings -->
    <property name="connection.driver_class">com.mysql.jdbc.Driver</property>
    <property name="connection.url">jdbc:mysql://localhost:3306/mywork</property>
    <property name="connection.username">****</property>
    <property name="connection.password">*****</property>

    <!-- JDBC connection pool (use the built-in) -->
    <property name="connection.pool_size">1</property>

    <!-- SQL dialect -->
    <property name="dialect">
        org.hibernate.dialect.MySQL5Dialect
    </property>

    <!-- Enable Hibernate's automatic session context management -->
    <property name="current_session_context_class">thread</property>

    <property name="cache.use_query_cache">true</property>
    <property name="cache.use_second_level_cache">true</property>
    <property name="cache.use_structured_entries">true</property>

    <!-- Echo all executed SQL to stdout -->
    <property name="show_sql">true</property>
    <property name="hbm2ddl.auto">create</property>

    <mapping class="com.parvez.hibernate.model.User"/>

</session-factory>

Java代码HB2Test.java

package com.parvez.hibernate.model;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;


public class HB2Test {

    private static SessionFactory sessionFactory;
    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub

        User myUser = new User();
        myUser.setUserId(1);
        myUser.setUserName("Superman");

        /*StandardServiceRegistryBuilder builder = new    StandardServiceRegistryBuilder();

        //create session factory
        Configuration configuration = new Configuration();
        SessionFactory sessionFactory = configuration.configure().
                    buildSessionFactory(builder.applySettings(configuration.getProperties()).build());

        Session session = sessionFactory.openSession();
     */

    Configuration configuration = new Configuration().configure("hibernate.cfg.xml");

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

        sessionFactory =     configuration.buildSessionFactory(serviceRegistry);

        Session session = sessionFactory.openSession();
        session.beginTransaction();

        session.save(myUser);

        session.getTransaction().commit();
        session.close();
    }

}

我得到的错误是

我尝试了多种初始化 SessionFactory 的方法，但似乎没有任何效果。我正在使用 Hibernate 4.3.8-Final

对于 hibernate 5.X +添加以下依赖项:

 <!-- provide second level caching functionality -->
    <!-- https://mvnrepository.com/artifact/org.ehcache/ehcache -->
    <dependency>
        <groupId>org.ehcache</groupId>
        <artifactId>ehcache</artifactId>
        <version>3.4.0</version>
    </dependency>


    <!-- provide ehcache integration with hibernate -->
    <!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-ehcache -->
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-ehcache</artifactId>
        <version>5.2.8.Final</version>
    </dependency>

将以下内容添加到您的 hibernate.cfg.xml 文件中

<property name="hibernate.cache.use_second_level_cache">true</property>
<property name="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory</property>
<property name="hibernate.cache.provider_class">net.sf.ehcache.hibernate.EhCacheProvider</property>
