我想用 HibernateOGM 编写一个非常简单的示例来填充 MongoDB 中的集合，但是如果我运行我的程序，我会得到这个异常：
线程“主”org.hibernate.MappingException 中的异常：无法获取 org.hibernate.ogm.persister.OgmEntityPersister 的构造函数
这是我的堆栈跟踪：
*at org.hibernate.persister.internal.PersisterFactoryImpl.create(PersisterFactoryImpl.java:185)
at org.hibernate.persister.internal.PersisterFactoryImpl.createEntityPersister(PersisterFactoryImpl.java:135)
at org.hibernate.internal.SessionFactoryImpl.<init>(SessionFactoryImpl.java:383)
at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1750)
at hogm.hibernateogm_mongodb.App.main(App.java:30)*
他是我的 POJO：
public class Contact {
@Id
private Long id;
private String email;
private String firstname;
private String lastname;
public String getEmail() {
return email;
}
/**
* @param email the email to set
*/
public void setEmail(String email) {
this.email = email;
}
在这里你可以找到我的hibernate.cfg.xml：
<?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.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
<property name="hibernate.current_session_context_class">thread</property>
<property name="hibernate.ogm.datastore.provider">mongodb</property>
<property name="hibernate.ogm.mongodb.database">rcfdb</property>
<property name="hibernate.ogm.mongodb.host">127.0.0.1</property>
<property name="hibernate.ogm.mongodb.port">27017</property>
<mapping resource="hibernate-contact.hbm.xml"/>
</session-factory>
</hibernate-configuration>
和hbm.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="Untersuchungsraum.Contact" table="District">
<id column="id" type="integer" >
<generator class="native">
</generator>
</id>
<property name="firstname" type="java.lang.String">
<column name="Firstname"></column>
</property>
<property name="lastname" type="java.lang.String">
<column name="lastname"></column>
</property>
<property name="email" type="java.lang.String">
<column name="email"></column>
</property>
</class>
</hibernate-mapping>
你有解决这个问题的想法吗？谢谢
