休眠无法找到默认提供

建议，我发现是：

1. 使用Hibernate 4+
2. 用户休眠验证4+
个
3. 添加Hibernate验证库
4. 添加JSR305（IMO并没有真正物）
5. 添加的javax验证库
6. 添加Hibernate验证器的注释处理器

我的所有，但仍然得到错误。

编辑：

显示我如何使用我的休眠。

<hibernate-configuration> 
    <session-factory> 
     <property name="hibernate.connection.driver_class">net.sourceforge.jtds.jdbc.Driver</property> 
     <property name="hibernate.connection.pool_size">5</property> 
     <property name="show_sql">false</property> 
     <property name="dialect">org.hibernate.dialect.SQLServerDialect</property> 
     <property name="hibernate.current_session_context_class">thread</property> 


     <mapping class="com.foo.bar.MyClass /> 
    </session-factory> 
</hibernate-configuration> 

大厦：

private static SessionFactory buildSessionFactory() { 

    try { 
     // Create the SessionFactory from hibernate.cfg.xml 
     Configuration configuration = new Configuration(); 
     configuration.configure(); 

     configuration.setNamingStrategy(ImprovedNamingStrategy.INSTANCE); // also other configuration changes made here 

     serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry(); 

     return configuration.buildSessionFactory(serviceRegistry); // this line gives the error 


    } catch (Throwable ex) { 
     // Make sure you log the exception, as it might be swallowed 
     log.error("Initial SessionFactory creation failed.", ex); 
     throw new ExceptionInInitializerError(ex); 
    } 
} 

Answer 1

关于你提到的6分：

• 使用Hibernate 4+
• 用户冬眠验证4+

Hibernate验证4.x版是参考实现对Bean验证的认识。这是使用的正确版本。它集成在休眠4.所以版本似乎是正确

• 添加Hibernate验证库

是的，这是必需的，你这样做，通过添加休眠-验证依赖。

• 添加JSR305（IMO并没有真正物）

没有关系的。甚至不知道JSR是什么。

• 添加的javax验证库

你这样做明确的，但同时又是一个传递依赖于休眠，验证所以你会得到他们任何一种方式。

• 添加Hibernate验证器的注释处理器

不，这不是必需/相关

那么，为什么它不工作？我想回答这个问题我们需要更多的信息。异常暗示javax.validation.Validation无法看到/加载Hibernate Validator Bean验证提供程序。你是否在受限制的班级工作？你如何使用所有这些依赖关系？
