Question

我试图将hibernate从3.6.10升级到4.3.11，但我遇到了多个问题。首先，在hibernate 3.x中有EntityMode会话，其中包括：

Session session = sessionFactory.openSession().getSession(EntityMode.MAP);

但是在hibernate-4.x中删除了对实体模式会话的支持（参见EntityMode.Map with Hibernate 4.2.6+ Spring 3.2）。在4.x中，解决方案是使用 hibernate.default_entity_mode = dynamic-map 配置自定义SessionFactory，但在我的情况下不起作用 - 我得到一个例外：

我配置了一个示例项目，试图找出问题所在。我的hibernate配置（test.hibernate.cfg.xml）：

<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">org.h2.Driver</property>
        <property name="hibernate.connection.password">sa</property>
        <property name="hibernate.connection.url">jdbc:h2:./target/test</property>
        <property name="hibernate.connection.username">sa</property>
        <property name="hibernate.dialect">org.hibernate.dialect.H2Dialect</property>
        <property name="hibernate.hbm2ddl.auto">update</property>
        <property name="hibernate.default_entity_mode">dynamic-map</property>
        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>

        <mapping resource="mapping/User.hbm.xml" />
    </session-factory>
</hibernate-configuration>

映射User.hbm.xml文件：

<hibernate-mapping>
    <class entity-name="user" name="test.moro.User" table="USER">
        <id name="id" type="long">
            <column name="ID" />
            <generator class="identity" />
        </id>
        <property name="name" type="java.lang.String">
            <column name="NAME" />
        </property>
        <property name="password" type="java.lang.String">
            <column name="PASSWORD" />
        </property>
    </class>
</hibernate-mapping>

实体：

public class User  implements Serializable {
    private long id;
    private String name;
    private String password;

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

测试类运行代码：

public class HibernateDynamicMapTest {

    @Test
    public void test_1() {
        Configuration configuration = new Configuration();
        configuration.configure("/test.hibernate.cfg.xml");
        StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
        SessionFactory sessionFactory = configuration.buildSessionFactory(builder.build());
        //------------------------------

        Session session = sessionFactory.openSession();
        session.beginTransaction();
        Map insertMap = new HashMap();
        insertMap.put("name", "User_1");
        insertMap.put("password", "mypassword");
        session.save("user", insertMap);
        session.getTransaction().commit();
        session.close();
        sessionFactory.close();
    }
}

请帮我解决这个错误。

P.S。我观察到如果我从类映射中删除 name =＆＃34; test.moro.User＆＃34;

<class entity-name="user" name="test.moro.User" table="USER">...</class>

它正在工作，但我需要保留类的名称，因为它用于将hbm映射到java实体。

升级到Hibernate 4.x default_entity_mode =动态映射异常
