Question

所以我正在研究我的毕业设计，我遇到了这个问题：

Exception in thread "main" java.lang.ExceptionInInitializerError: Initial SessionFactory failedorg.hibernate.boot.InvalidMappingException: Could not parse mapping document: Beans/Receptions.hbm.xml (RESOURCE)
at Logic.HibernateSessionFactory.buildSessionFactory(HibernateSessionFactory.java:25)

at java.lang.reflect.Method.invoke(Method.java:498)
at com.intellij.rt.execution.application.AppMain.main(AppMain.java:147)

使用退出代码1完成处理

Receptions.hbm.xml：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-mapping PUBLIC

    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

Receptions.java：

package Beans;

import javax.persistence.Basic;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import java.sql.Date;

@Entity
public class Receptions {
    private int recNum;
    private int docPass;
    private int regNum;

    @Id
    @Column(name = "recNum", nullable = false)
    public int getRecNum() {
        return recNum;
    }

    public void setRecNum(int recNum) {
        this.recNum = recNum;
    }

    @Basic
    @Column(name = "docPass", nullable = false)
    public int getDocPass() {
        return docPass;
    }

    public void setDocPass(int docPass) {
        this.docPass = docPass;
    }

    @Basic
    @Column(name = "regNum", nullable = false)
    public int getRegNum() {
        return regNum;
    }

    public void setRegNum(int regNum) {
        this.regNum = regNum;
    }

    @Basic
    @Column(name = "recDate", nullable = false)
    public Date getRecDate() {
        return recDate;
    }

    public void setRecDate(Date recDate) {
        this.recDate = recDate;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;

        Receptions that = (Receptions) o;

        if (recNum != that.recNum) return false;
        if (docPass != that.docPass) return false;
        if (regNum != that.regNum) return false;
        if (recDate != null ? !recDate.equals(that.recDate) : that.recDate != null) return false;

        return true;
    }

    @Override
    public int hashCode() {
        int result = recNum;
        result = 31 * result + docPass;
        result = 31 * result + regNum;
        result = 31 * result + (recDate != null ? recDate.hashCode() : 0);
        return result;
    }
}

POJO类和映射文件是由IDEA生成的，但它一直说它无法解析文件。我的项目结构看起来像this

你可以给我一些提示吗？我不明白它有什么问题，映射文件对我来说很好看

Answer 1

在此设置中，有两件事我很奇怪： a）为什么在实体上同时具有映射xml和带注释的映射？似乎多余/不正确。新版本的hibernate倾向于消除对xml配置文件的需求。

b）在你的xml上，这个＆＃34;类名=＆＃34; Beans.Receptions＆＃34;看起来不对劲如果hbm文件在包本身内，它不应该需要前缀，我试试用＃34; class name =＆＃34; Receptions＆＃34;
