Hibernate Eclipse未知实体（使用javax.persistence.Entity）

为了解决eclipse中未知实体的问题，我整天都在尝试和搜索。 我使用单独的.java和hbm.xml文件

我的实体类是Account.java

而且从

package com.mywebservice.utils;

import org.hibernate.Session;
import org.hibernate.Query;
import com.mywebservice.domain.*;
import org.hibernate.annotations.*;

public class HibernateTest {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        Session session = SessionFactoryUtil.getSessionFactory().getCurrentSession();
        session.beginTransaction();
        getAccount(session);

    }

    public static void getAccount(Session session) {
        Account acc = new Account();

        acc.setEmpId("123456789");

        session.save(acc);

        System.out.println("Saved!");
    }

}

此外，我还在hibernate.cfg.xml中添加了类的映射

<?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">

        <property name="hibernate.connection.password">hrportal@123</property>
        <property name="hibernate.connection.url">jdbc:sqlserver://HQ-10063332D\SQLEXPRESS;DatabaseName=EPP</property>

        <property name="hibernate.dialect">org.hibernate.dialect.SQLServer2008Dialect</property>        

       <property name="hibernate.current_session_context_class">thread</property>

       <mapping class="com.mywebservice.domain.Account" />
    </session-factory>
</hibernate-configuration>

我相信您在hibernate映射中缺少了

包

属性。尝试更新

hbm

文件中的映射部分，如下所示：

<hibernate-mapping package="com.mywebservice.domain">

您的

帐户

类位于包

com.mywebservice.domain

，因此在

Account.hbm.xml

类中，名称应该是

com.mywebservice.domain.Account

而不仅仅是

Account

如果使用xml配置bean，为什么要使用annotationConfiguration构建会话，可以使用AnnotationConfig进行尝试。may很管用。

回答我自己的问题，所以它将来可能会帮助其他人

在我的hibernate.cfg.xml中，映射应该如下

<mapping resource="com/mywebservice/domain/Account.hbm.xml"></mapping>

而不是

<mapping class="com.mywebservice.domain.Account" />

同样在更正了hibernate.cfg.xml之后，我得到了一个错误 “无法启动默认tuplizer”，为此，我必须添加一个名为javassist.jar的库，它可以工作：）

好运

更新了问题。堆栈跟踪添加您使用的

AnnotationConfiguration

（已弃用）没有注释。您可以使用

hibernate.cfg.xml

而不使用

org.hibernate.cfg.Configuration（）

。选择一种方式，两种方式都不起作用。#jesse如果我不使用AnnotationConfiguration对象，它会给出异常“需要使用AnnotationConfiguration实例”

<mapping resource="com/mywebservice/domain/Account.hbm.xml"></mapping>

<mapping class="com.mywebservice.domain.Account" />
