我正在尝试将 Hibernate 与 GWT 一起使用，但出现此错误：

org.hibernate.MappingException: Unknown entity: com.asso.shared.Personne

我不明白为什么我得到这个错误！我正在使用注释，这些类是由 Hibernate 生成的！Personne 类：

package com.asso.shared;

我用来持久化 Personne 类的方法：

public int ajouterAdherent(Personne p) {
        Session session = HibernateUtil.currentSession();
        Transaction tx = null;
        System.out.println("insertion");
        try {
            tx = session.beginTransaction();
            p.toString();
            session.save(p);
            tx.commit();

        } catch (Exception e) {
            if (tx != null) {
                tx.rollback();
                HibernateUtil.closeSession();
                e.printStackTrace();
            }
            HibernateUtil.closeSession();
            return -1;
        }
        return 1;
    }

这是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">

这个问题与 GWT 无关。

你得到： org.hibernate.MappingException 因为 Hibernate 不知道你的实体类。你必须添加

<mapping class="com.asso.shared.Personne"/>

在 hbm.xml 文件中，或创建 SessionFactory

sessionFactory = new AnnotationConfiguration()
                   .addAnnotatedClass(...)

阅读http://docs.jboss.org/hibernate/annotations/3.5/reference/en/html/ch01.html
