寻找一个不被弃用的会话工厂 [英] Looking for a not-deprecated session-factory

问题描述

  AnnotationConfiguration 
 
我正在处理hibernate，当我打开当前项目时我发现我的Session-Factory已被弃用。 af = new AnnotationConfiguration（）; 
 SessionFactory factory = af.configure（）。buildSessionFactory（）; 
会话会话= factory.openSession（）; 
  

AnnotationConfiguration现在似乎已被废弃......所以我查了JavaDoc，至：

org.hibernate.cfg.Configuration

我的代码到目前为止工作正常，实际上我不想改变它......但是我搜索了一下，发现有人在问自己同样的问题，为什么SessionFactory需要更改...
http://rgordon.co.uk/blog/ 2012/02/24 / hibernate-please-dont-deprecate-yourself /

这篇文章是从2012年开始的以这种方式描述一切：

  ServiceRegistryBuilder serviceRegistryBuilder = new ServiceRegistryBuilder（）; 
 serviceRegistryBuilder.applySettings（properties）; 
 ServiceRegistry serviceRegistry = serviceRegistryBuilder.buildServiceRegistry（）; 
 
 Configuration configuration = new Configuration（）。addClass（FeedTradePersistable.class）; 
 
 SessionFactory sessionFactory = configuration.buildSessionFactory（serviceRegistry）; 
  

我实现了这一点。 JavaDoc证明了错误 - 再次！已过时。
它指的是：

org.hibernate.boot.registry.StandardServiceRegistryBuilder

我再次使用了Google。结果并不令人满意......

我开始修改代码...

  ServiceRegistry serviceRegistry = serviceRegistryBuilder.build（）; 
配置配置=新配置（）; 
 SessionFactory sessionFactory = configuration.buildSessionFactory（serviceRegistry）; 
 Session session = sessionFactory.openSession（）; 
  

引发异常...

< blockquote>

org.hibernate.HibernateException：当
'hibernate.dialect'未设置时，连接不能为空

at line：

  SessionFactory sessionFactory = configuration.buildSessionFactory（serviceRegistry）; 
  

我确定这是因为我没有指定任何配置设置。其实我不想。我对hibernate.cfg.xml感到满意。

我使用了配置文件.addFile（.. - 没有那么成功......

有没有人对此有所了解？
谢谢

更新：（hibernate.cfg.xml ）

更新（2014年2月16日）：
我认为有必要向你展示我的pom.xml。我花了一段时间，直到我找出Hibernate-Framework的哪个组合适用于我...

解决方案

为此付出一些努力并进行了一些研究：

http://www.codejava.net/frameworks/hibernate/building-hibernate-sessionfactory-from-service-registry
提供了一个现代 HibernateUtil ：

  import org.hibernate.SessionFactory; 
导入org.hibernate.cfg.Configuration; 
 import org.hibernate.service.ServiceRegistry; 
 import org.hibernate.service.ServiceRegistryBuilder; 
 
 public class HibernateUtil {
 
 private static SessionFactory sessionFactory; 
 $ b $ public static SessionFactory getSessionFactory（）{
 if（sessionFactory == null）{
 Configuration configuration = new Configuration（）。configure（）; 
 ServiceRegistryBuilder registry = new ServiceRegistryBuilder（）; 
 registry.applySettings（configuration.getProperties（））; 
 ServiceRegistry serviceRegistry = registry.buildServiceRegistry（）; 
 
 sessionFactory = configuration.buildSessionFactory（serviceRegistry）; 
} 
 
 return sessionFactory; 
} 
 
} 
  

尽管此版本似乎有效还有：

  import java.util.logging.Level; 
 import java.util.logging.Logger; 
 import org.hibernate.SessionFactory; 
导入org.hibernate.cfg.Configuration; 
 
 public class HibernateUtil {
 
 private static final SessionFactory sessionFactory; 
 
 static {
 try {
 Configuration cfg = new Configuration（）; 
 sessionFactory = cfg.configure（hibernate.cfg.xml）。buildSessionFactory（）; 
} catch（Throwable ex）{
 Logger.getLogger（HibernateUtil.class.getName（））.log（Level.SEVERE，null，ex）; 
抛出新的ExceptionInInitializerError（ex）; 
 
 
 
 public static SessionFactory getSessionFactory（）{
 return sessionFactory; 
} 
  

}

但我的问题是我不想将新版本与旧版本集成在一起。更新后，我遇到了一个

java.lang.NoSuchMethodError：
org.hibernate.annotations.common.reflection.java。通常，JavaReflectionManager.injectClassLoaderDelegate（Lorg / hibernate / annotations / common / reflection / ClassLoaderDelegate;）V

。
烦人。通常 Mkyong 提供了很好的解决方案，但在我的情况下，他写了 Stackoverflow 的相反解决方案。 。

因此，我搜索了一些存储库，发现了一个令人震惊的简单解决方案（比较： http://hibernate.org/orm/downloads/ ）：

< dependency> 
< groupId> org.hibernate< / groupId> 
< artifactId> hibernate-core< / artifactId> 
< version> 5.0.0.Final< / version> 
< /依赖关系> 
  

一些其他小问题阻止了我：
在 hibernate .cfg.xml 我必须将行从 update 更改为 auto ： p>

 < property name =hbm2ddl.auto> auto< / property> 
  

将它与我旧的pom.xml进行比较... - 当时我有第一次遭遇与Hibernate并添加了一切似乎有用，直到它的工作。在这样做之后，我不再接触它......几乎两年......永远不要改变一个胜利的团队，对吧？

I am dealing with hibernate and as I opened my current project I figured out my Session-Factory is deprecated:

AnnotationConfiguration af = new AnnotationConfiguration();
SessionFactory factory = af.configure().buildSessionFactory();
Session session = factory.openSession();

AnnotationConfiguration seems to be deprecated by now... So I checked the JavaDoc and I got told it moved to:

org.hibernate.cfg.Configuration

My code works fine so far, actually I don't want to change it... But I googled and found someone who's asking himself the same question whythe SessionFactory needs to be changed... http://rgordon.co.uk/blog/2012/02/24/hibernate-please-dont-deprecate-yourself/

The Article is from 2012 (so not that old...) and describes everything in that way:

ServiceRegistryBuilder serviceRegistryBuilder = new ServiceRegistryBuilder();
serviceRegistryBuilder.applySettings(properties);
ServiceRegistry serviceRegistry = serviceRegistryBuilder.buildServiceRegistry();

Configuration configuration = new Configuration().addClass(FeedTradePersistable.class);

SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);

I implemented that. The JavaDoc proves that wrong - again! Deprecated. It refers to:

org.hibernate.boot.registry.StandardServiceRegistryBuilder

I googled that again. The results weren't so satisfying...

I started to modify the code...

ServiceRegistry serviceRegistry = serviceRegistryBuilder.build();
Configuration configuration = new Configuration();
SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);
Session session = sessionFactory.openSession();

And an exception is thrown...

org.hibernate.HibernateException: Connection cannot be null when 'hibernate.dialect' not set

at line:

SessionFactory sessionFactory = configuration.buildSessionFactory(serviceRegistry);

I am pretty sure this is because I haven't specified any configuration-settings. Actually, I don't want to. I feel comfortable with the hibernate.cfg.xml.

I played a bit around with configuration.addFile(.. - wasn't that successful...

Has anyone an idea about that? Thanks

UPDATE: (hibernate.cfg.xml)

<?xml version="1.0" encoding="UTF-8"?>

UPDATE (16. Feb 2014): I think it is necessary to show you my pom.xml as well. It took me a while until I figured out which combination of the Hibernate-Framework works for me...

解决方案

As I got some time to modernize my software I decided to put some effort into it and did some research:

http://www.codejava.net/frameworks/hibernate/building-hibernate-sessionfactory-from-service-registry provides a modern HibernateUtil:

import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;

public class HibernateUtil {

private static SessionFactory sessionFactory;

public static SessionFactory getSessionFactory() {
    if (sessionFactory == null) {
        Configuration configuration = new Configuration().configure();
        ServiceRegistryBuilder registry = new ServiceRegistryBuilder();
        registry.applySettings(configuration.getProperties());
        ServiceRegistry serviceRegistry = registry.buildServiceRegistry();

        sessionFactory = configuration.buildSessionFactory(serviceRegistry);            
    }

    return sessionFactory;
}

}

Even though this version seems to work as well:

import java.util.logging.Level;
import java.util.logging.Logger;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class HibernateUtil {

private static final SessionFactory sessionFactory;

static {
    try {
        Configuration cfg = new Configuration();
        sessionFactory = cfg.configure("hibernate.cfg.xml").buildSessionFactory();
    } catch (Throwable ex) {
        Logger.getLogger(HibernateUtil.class.getName()).log(Level.SEVERE, null, ex);
        throw new ExceptionInInitializerError(ex);
    }
}

public static SessionFactory getSessionFactory() {
    return sessionFactory;
}

}

But my problem was I didn't want to integrate a new version with the old libs. After updating I ran into a

java.lang.NoSuchMethodError: org.hibernate.annotations.common.reflection.java.JavaReflectionManager.injectClassLoaderDelegate(Lorg/hibernate/annotations/common/reflection/ClassLoaderDelegate;)V

often. Annoying. Usually Mkyong provides good solutions, but in my case he wrote the opposite solution of Stackoverflow...

So I searched some repositories and found a shockingly easy solution (compare: http://hibernate.org/orm/downloads/):

<!-- HIBERNATE -->
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>5.0.0.Final</version>
</dependency>

Some other minor issues which stopped me: In the hibernate.cfg.xml I had to change the line from update to auto:

<property name="hbm2ddl.auto">auto</property> 

Compare it to my old pom.xml... - back then I had my first "encounter" with Hibernate and added everything which seemed useful until it worked. After it did so I stopped touching it for... Almost two years... Never change a "winning" team, right?
