加載映射文件休眠4

Question

從

<?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> 

映射文件是沒有得到在SessionFactory

異常加載hibernate.cfg.xml文件加載映射文件時碰到的問題在線程 「主要」 org.hibernate.MappingException：未知 實體：com.test.dto.User

，但如果我添加映射manua lly在Configuration實例中：

static { 
     Configuration config = new Configuration().configure().addResource("User.hbm.xml"); 

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

    } 

映射工作正常......，有什麼建議？

看起來像一個問題是一樣的here。您不能將配置與new Configuration().configure()和config.buildSessionFactory(registry)混合。您應該使用StandardServiceRegistryBuilder進行所有配置。 類似這樣的東西

ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder(). 
    configure().build(); 
SessionFactory sessionFactory= new Configuration().buildSessionFactory(serviceRegistry);
