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

标签： java hibernate

我已经开始使用Hibernate 4.3.8并且正在尝试插入和检索用户的基本程序。以下是我的文件。

的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

我尝试了不同的初始化SessionFactory的方法，但似乎没有任何效果。我正在使用Hibernate 4.3.8-Final

对于休眠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>


在hibernate.cfg.xml文件中添加以下内容

<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>

通过修改hibernate.cfg.xml中的属性来禁用缓存，如下所示：

for link in soup.find_all('a'):
    Href_q.write(link.get('href')+ '\t' + link.get('target') + '\n')
Href_q.close()

确保pom.xml文件中的hibernate和hibernate-ehcache使用相同的版本。请参考以下内容：

<!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-core -->
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.4.10.Final</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>5.4.10.Final</version>
    </dependency>

在hibernate.cfg文件中，使用以下属性

<property name="hibernate.cache.use_second_level_cache">true</property>
    <property name="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.internal.EhcacheRegionFactory</property>

应用@Solanki 's answer时。请注意，您会收到以下消息：

class page1 extends React.Component {
  render() {
    const admin = false;

    if (!admin) return <></>

    return (
    <div>
    
        <button onClick={this.deleteThis}>hello</button>
        <button onClick={this.deleteThis}>hello</button>
        <button onClick={this.deleteThis}>hello</button>
        <button onClick={this.deleteEverything}>hello</button>

    </div>

    
 );
  }
}

要解决此问题，您需要使用EhCacheRegionFactory。

意思是，您的applicationContext实际上应该像：

HHH020100: The Ehcache second-level cache provider for Hibernate is deprecated.  See https://hibernate.atlassian.net/browse/HHH-12441 for details.

在sessionFactoryBean的配置中，删除属性<bean name="ehcacheRegionFactory" class="org.hibernate.cache.ehcache.internal.SingletonEhcacheRegionFactory"/> ... 和hibernate.cache.region.factory_class。

然后添加：

net.sf.ehcache.hibernate.EhCacheProvider

创建类似这样的内容：

<property name="cacheRegionFactory" ref="ehcacheRegionFactory"/>

在hibernate.cfg.xml中禁用二级缓存。

包含以下代码行以禁用二级缓存。 

<!-- Disable the second-level cache -->
    <property 
name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

摆脱与缓存相关的三个配置......你应该很好
