加载映射文件Hibernate 4 [英] Loading mapping file Hibernate 4

问题描述

从hibernate.cfg.xml文件加载映射文件时遇到问题

 <？xml version =1.0encoding =UTF-8？> 
<！DOCTYPE hibernate-configuration PUBLIC -  // Hibernate / Hibernate配置DTD 3.0 // EN
http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd\"> ; 
< hibernate-configuration> 
< session-factory> 
< property name =hibernate.connection.driver_class> org.hsqldb.jdbcDriver< / property> 
< property name =hibernate.connection.url> jdbc：hsqldb：hsql：// localhost< / property> 
< property name =hibernate.dialect> org.hibernate.dialect.HSQLDialect< / property> 
< property name =hibernate.hbm2ddl.auto> create-drop< / property> 
< mapping resource =User.hbm.xml/> 
< / session-factory> 
< / hibernate-configuration> 
  

映射文件没有被加载到 SessionFactory $ b

线程main中的异常org.hibernate.MappingException：未知
实体：com.test.dto.User

但是如果我在配置实例中手动添加映射：

  static {
 Configuration config = new Configuration（）。configure（）。addResource（User.hbm.xml） ; 
 
 ServiceRegistry registry = new StandardServiceRegistryBuilder（）。applySettings（config.getProperties（））。build（）; 
 sessionFactory = config.buildSessionFactory（registry）; 
 
 
 
 
 $ b 
映射工作正常......，有什么建议？ 
解决方案
看起来像一个问题是一样的此处。您不能将配置与新配置（）。configure（）和 config.buildSessionFactory（注册表）混合。您应该使用 StandardServiceRegistryBuilder 进行所有配置。 
像这样
  ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder（）。 
 configure（）。build（）; 
 SessionFactory sessionFactory = new Configuration（）。buildSessionFactory（serviceRegistry）; 
  
 
I'm having problems when loading a mapping file from the hibernate.cfg.xml file
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
                                         "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
 <session-factory>
  <property name="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</property>
  <property name="hibernate.connection.url">jdbc:hsqldb:hsql://localhost</property>
  <property name="hibernate.dialect">org.hibernate.dialect.HSQLDialect</property>
  <property name="hibernate.hbm2ddl.auto">create-drop</property>
  <mapping resource="User.hbm.xml"/>
 </session-factory>
</hibernate-configuration>
The mapping file is not getting loaded in the SessionFactory

  
Exception in thread "main" org.hibernate.MappingException: Unknown
  entity: com.test.dto.User
but if i add the mapping manually in the Configuration instance:
static {
        Configuration config = new Configuration().configure().addResource("User.hbm.xml");

        ServiceRegistry registry = new StandardServiceRegistryBuilder().applySettings(config.getProperties()).build();
        sessionFactory = config.buildSessionFactory(registry);

    }
The mapping works correctly..., any suggestions??
解决方案
Looks like a problem is the same as here. You can't mix configurations with new Configuration().configure() and config.buildSessionFactory(registry). You should do all configuration with StandardServiceRegistryBuilder. 
Something like this
ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().
    configure().build();
SessionFactory sessionFactory= new Configuration().buildSessionFactory(serviceRegistry);
