使用hibernate，hibernate注释和ehcache的Maven依赖关系是什么？ [英] What are the Maven dependencies to use hibernate, hibernate annotations, and ehcache?

问题描述

我想使用最新的hibernate，hibernate-annotations和ehcache依赖来更新我的Maven pom.xml。

我阅读了hibernate的下载页面和ehcache donwload页面。我所有的尝试解释它似乎都失败了。有人可以写出应该进入pom.xml的片段吗？

Cryptic hibernate下载页面：
http://hibernate.org/downloads

Cryptic ehcache下载页面：
http://www.terracotta.org/dl/ehcache-oss-download-catalog

这是我到目前为止所有的：

我知道，它看起来像一个大混乱，因为我似乎没有弄清楚，所有的依赖项都存储起来。

以上失败：

 调用init方法失败;嵌套异常是java.lang.NullPointerException 
在org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveReference（BeanDefinitionValueResolver.java:328）
  

更新：
帕斯卡尔，你的回答很清楚，很好解释。但是，hibernate在启动时仍然失败。

1. sl4j抛出错误，后者添加：

    <依赖关系> 
   < groupId> org.slf4j< / groupId> 
   < artifactId> slf4j-log4j12< / artifactId> 
   < version> 1.6.1< / version>

2. 这个警告有很多例子：

    1797 [main] WARN net.sf.ehcache.hibernate.AbstractEhcacheRegionFactory  -  No Tr 
    ansactionManagerLookup在Hibernate配置中找到，XA缓存将被参与
     




3. 此外，此错误使一切失败：

   
   
   

   相关原因：

     org.springframework.beans.factory.BeanCreationException：在ServletContext资源中定义的

    PointerException 
   在org.springframework.beans.factory.support.BeanDefinitionValueResolver

要确认，这是弹簧配置：

< prop key =net.sf.ehcache.configurationResourceName> /ehcache.xml< / prop> 
  

更新：
这似乎是hibernate被卡住的最新异常： p>

 导致：java.lang.NullPointerException 
在net.sf.ehcache.hibernate.HibernateUtil.loadAndCorrectConfiguration（HibernateUtil.java ：48）

在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean（AbstractAutowireCapableBeanFactory.java:1409）
  

解决方案

如果你真的意味着hibernate-annotations（而不是hibernate-entitymanager）和ehcache的终极版本，那么你将需要以下：

 < project> 
 ... 
<依赖关系> 
<依赖关系> 
< groupId> org.hibernate< / groupId> 
< artifactId> hibernate-core< / artifactId> 
< version> 3.6.0.Final< / version> 
< / dependency> 
<依赖关系> 
< groupId> net.sf.ehcache< / groupId> 
< artifactId> ehcache-core< / artifactId> 
< version> 2.2.0< / version> 
< / dependency> 
 ... 
< / dependencies> 
 
< repositories> 
< repository> 
< id> repository.jboss.org-public< / id> 
< name> JBoss存储库< / name> 
< url> https：//repository.jboss.org/nexus/content/groups/public< / url> 
< / repository> 
< / repositories> 
 ... 
< / project> 
  

截至Hibernate 3.6，JDK 1.4的支持已经被删除，Hibernate注释已经被并入Core

我的意思是Hibernate EntityManager，然后将 hibernate-core 替换为 hibernate-entitymanager

关于EHCache， ehcache-core 应该提供一切你需要（包括实现新 Hibernate 3.3 / 3.5缓存SPI 及其 CacheRegionFactory ）。因此，如记录的：

将Ehcache设置为休眠二级缓存

< h3> Hibernate 3.3及更高版本

注意HIBERNATE 3.2 USERS

确保注意到BOTH属性名称和值的更改。

使用：

 < property name =hibernate.cache.region.factory_class> 
 net.sf.ehcache.hibernate.EhCacheRegionFactory< / property> 
  

例如创建，或

 < property name =hibernate.cache.region.factory_class> 
 net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory< / property> 
  

强制Hibernate使用Ehcache CacheManager的单例
。

后续行动：要回答您的更新：

sl4j抛出错误，这是通过添加（...）而消失的。

嗯，我不能猜测你正在使用什么样的日志框架，提供你选择的绑定作为读者的一个练习：）

这个警告有很多例子（...）

我只得到一个 警告 在非JTA环境中运行。如果是这种情况（非JTA环境），我会考虑 WARNING 正常。如果不是这样，请查看有关 JTA 的文档。

此外，这个错误使一切失败

这是一个不同的问题（但它看起来像 SessionFactory 无法正确初始化，激活日志记录以了解原因），我建议发布一个新的春季特定问题。

I would like to update my Maven pom.xml with the latest hibernate, hibernate-annotations, and ehcache dependencies.

I read the hibernate download page and the ehcache donwload page. All my tries at interpreting it seem to fail. Can someone write out the snippet that should go into pom.xml?

I know, it looks like a big mess, because I don't seem to figure out, where all the dependencies are stored.

The above fails with:

Invocation of init method failed; nested exception is java.lang.NullPointerException
    at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveReference(BeanDefinitionValueResolver.java:328)

Update: Pascal, your reply is very clear and well explained. However, hibernate still fails on startup.

1. sl4j threw errors, which went away by adding:

   <dependency>
       <groupId>org.slf4j</groupId>
       <artifactId>slf4j-log4j12</artifactId>
       <version>1.6.1</version>
   </dependency>
   

2. There are many instances of this warning:

   g in the two-phase commit!
   1797 [main] WARN  net.sf.ehcache.hibernate.AbstractEhcacheRegionFactory  - No Tr
   ansactionManagerLookup found in Hibernate config, XA Caches will be participatin
   

3. Additionally, this error makes everything fail:

   Related cause:

   org.springframework.beans.factory.BeanCreationException: Error creating bean wit
   h name 'financialDAO' defined in ServletContext resource [/WEB-INF/config/applic
   ationContext-database.xml]: Cannot resolve reference to bean 'transactionManager

   PointerException
       at org.springframework.beans.factory.support.BeanDefinitionValueResolver
   .resolveReference(BeanDefinitionValueResolver.java:328)
   

To confirm, this is the spring configuration:

<!-- Enable EHCache -->
<prop key="hibernate.cache.use_second_level_cache">true</prop>
<prop key="hibernate.cache.use_query_cache">false</prop>
<prop key="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</prop>
<prop key="net.sf.ehcache.configurationResourceName">/ehcache.xml</prop>

Update: This seems to be the latest exception that hibernate gets stuck on:

解决方案

If you really mean the ultimate versions of hibernate-annotations (and not hibernate-entitymanager) and ehcache, then you'll need the following:

<project>
  ...
  <dependencies>
    <dependency>
      <groupId>org.hibernate</groupId>
      <artifactId>hibernate-core</artifactId>
      <version>3.6.0.Final</version>
    </dependency>
    <dependency>
       <groupId>net.sf.ehcache</groupId>
       <artifactId>ehcache-core</artifactId>
       <version>2.2.0</version>
   </dependency>
   ...
  </dependencies>

  <repositories>
    <repository>
      <id>repository.jboss.org-public</id>
      <name>JBoss repository</name>
      <url>https://repository.jboss.org/nexus/content/groups/public</url>
    </repository>
  </repositories>
  ...
</project>

As of Hibernate 3.6, JDK 1.4 support has been dropped and the Hibernate Annotations have been merged back into Core.

I you meant Hibernate EntityManager, then replace hibernate-core by hibernate-entitymanager in the above snippet.

Regarding EHCache, ehcache-core should provide everything you need (including implementations of the "new" Hibernate 3.3/3.5 caching SPI with its CacheRegionFactory). So, as documented:

Setting Ehcache as the Hibernate Second Level Cache

Hibernate 3.3 and higher

ATTENTION HIBERNATE 3.2 USERS

Make sure to note the change to BOTH the property name and value.

Use:

<property name="hibernate.cache.region.factory_class">
          net.sf.ehcache.hibernate.EhCacheRegionFactory</property>

for instance creation, or

<property name="hibernate.cache.region.factory_class">
          net.sf.ehcache.hibernate.SingletonEhCacheRegionFactory</property>

to force Hibernate to use a singleton of Ehcache CacheManager.

Follow-up: To answer your update:

sl4j threw errors, which went away by adding (...)

Well, I can't guess what logging framework you're using, providing the binding of your choice was left as an exercise for the reader :)

There are many instances of this warning (...)

I get only one WARNING when running in a non JTA environment. If that's your case (a non JTA environment), I would consider the WARNING as normal. If that's not your case, have a look at the documentation about JTA.

Additionally, this error makes everything fail

This is somehow a different question (but it looks like the SessionFactory fails to initialize properly, activate logging to see why) and I suggest to post a new spring specific question.
