Spring Hibernate 映射问题

【问题标题】：Spring Hibernate Mapping IssueSpring Hibernate 映射问题
【发布时间】：2014-03-10 11:15:54
【问题描述】：

因为我是 Hibernate 和映射的新手。我无法找到这个原因的确切问题。当我找出问题的确切原因时，我会更新问题标题。运行 spring 项目时出现以下错误。 hbm.xml 是从 JBoss Hibernate 工具生成的。 （我会的）

下面给出了堆栈跟踪

我的模型位于另一个 maven 模块中。

这是注解 hbm.xml

这是我的 Annotation1 模型（我将 Annotation 更改为 Annotation1 以检查天气，这是问题所在。）

   package org.e.models;

public class Annotation1 implements java.io.Serializable {

    private static final long serialVersionUID = 2037771233820433553L;
    private Long id;
    private Resource resource;
    private Integer XPoint;
    private Integer YPoint;
    private Integer ZPoint;
    private String comment;

    public Annotation1() {
    }

    public Annotation1(Resource resource) {
        this.resource = resource;
    }

    public Annotation1(Resource resource, Integer XPoint, Integer YPoint,
            Integer ZPoint, String comment) {
        this.resource = resource;
        this.XPoint = XPoint;
        this.YPoint = YPoint;
        this.ZPoint = ZPoint;
        this.comment = comment;
    }

    public Long getId() {
        return this.id;
    }

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

    public Resource getResource() {
        return this.resource;
    }

    public void setResource(Resource resource) {
        this.resource = resource;
    }

    public Integer getXPoint() {
        return this.XPoint;
    }

    public void setXPoint(Integer XPoint) {
        this.XPoint = XPoint;
    }

    public Integer getYPoint() {
        return this.YPoint;
    }

    public void setYPoint(Integer YPoint) {
        this.YPoint = YPoint;
    }

    public Integer getZPoint() {
        return this.ZPoint;
    }

    public void setZPoint(Integer ZPoint) {
        this.ZPoint = ZPoint;
    }

    public String getComment() {
        return this.comment;
    }

    public void setComment(String comment) {
        this.comment = comment;
    }

}

这是我的 DAO 实现

    package org.e.persistance.dao.impli;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.e.models.Annotation1;
import org.e.persistance.dao.Annotation1DAO;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

@Repository("annotation1DAO")
public class Annotation1DAOImpli implements Annotation1DAO {

    private static final Log log = LogFactory.getLog(Annotation1DAOImpli.class);

    @Autowired
    private SessionFactory sessionFactory;

    public void persist(Annotation1 transientInstance) {
        log.debug("persisting Annotation1 instance");
        try {
            sessionFactory.getCurrentSession().persist(transientInstance);
            log.debug("persist successful");
        } catch (RuntimeException re) {
            log.error("persist failed", re);
            throw re;
        }
    }


    public void delete(Annotation1 persistentInstance) {
        log.debug("deleting Annotation1 instance");
        try {
            sessionFactory.getCurrentSession().delete(persistentInstance);
            log.debug("delete successful");
        } catch (RuntimeException re) {
            log.error("delete failed", re);
            throw re;
        }
    }

    public Annotation1 merge(Annotation1 detachedInstance) {
        log.debug("merging Annotation1 instance");
        try {
            Annotation1 result = (Annotation1) sessionFactory.getCurrentSession()
                    .merge(detachedInstance);
            log.debug("merge successful");
            return result;
        } catch (RuntimeException re) {
            log.error("merge failed", re);
            throw re;
        }
    }

    public Annotation1 findById(java.lang.Long id) {
        log.debug("getting Annotation1 instance with id: " + id);
        try {
            Annotation1 instance = (Annotation1) sessionFactory
                    .getCurrentSession().get("Annotation1", id);
            if (instance == null) {
                log.debug("get successful, no instance found");
            } else {
                log.debug("get successful, instance found");
            }
            return instance;
        } catch (RuntimeException re) {
            log.error("get failed", re);
            throw re;
        }
    }


}

抱歉，内容太长了。我非常感谢您对此提供的帮助。

谢谢

【问题讨论】：

  • 你可以发布你的休眠配置文件
  • @henrycharles 我已经添加了我的 hibernate.xml
  • 您的hibernate.xml 不是休眠配置文件。
  • @PeterRader 我将添加我正在使用的所有配置文件
  • 大家好，感谢您的大力帮助。它首先崩溃的原因是，hbm.xml 中的类不是完全合格的。在那之后，我得到了大多数人都提到了正确答案的错误。所以，我会为大家+1！ :)

标签： java spring hibernate


【解决方案1】：

您需要添加对将org.e.models.Annotation1 映射到Hibernate.xmllike 的映射文件的引用

<session-factory>
    <mapping resource="org/e/models/Annotation1.hbm.xml" />
</session-factory>

【讨论】：

  • 我已将其添加到 hibernate.xml 中。请看编辑。并感谢您的快速回复
  • @Diode 它说有一个类 org.endovantage.models.Annotation 没有任何映射。这是 org.e.models.Annotation1 类的副本吗？
  • 是的，我到处查看是否有任何遗漏的注释类需要手动重命名。那么是导致问题的原因吗？
  • @Diode 检查包 org.endovantage.models 并在不需要时删除 Annotation.java
  • 我试图删除它，它变得更糟了。映射中有一对多关系:(
【解决方案2】：

我认为您缺少这一行：

<mapping resource="path/to/your/annotation.hbm.xml"></mapping>

在你的hibernate.cfg.xml中。

【讨论】：

  • 我没有使用 hibernate.cfg.xml 文件。我在关注this article。他没有包括在内。他定义了一个hibernate.xml，我认为它的内容相同。请参阅编辑。非常感谢
【解决方案3】：

您的“注释”类未映射。添加

 <value>/hibernate/Annotation1.hbm.xml</value>

如果不存在则创建文件。

【讨论】：

  • 好的，我从 Annotation 改为 Annotation1 因为我认为这是问题的原因。我会将所有内容都更改回来并再次检查。
