Hibernate 关于注解的错误，请教下
[code=Java][/code]ERROR [ContainerBackgroundProcessor[StandardEngine[Catalina]]] ContextLoader.initWebApplicationContext(220) | Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor#0' defined in class path resource [spring/applicationContext-dao.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in file [F:\webserver\apache-tomcat-6.0.32\webapps\blognms\WEB-INF\classes\spring\applicationContext-dao.xml]: Invocation of init method failed; nested exception is org.hibernate.MappingException:
问题重点：
Foreign key (FKAECBABBE3114B171:ibokee_report_comment [post])) must have same number of columns as the referenced primary key (ibokee_wb_postcomment [postID,postComments_id])

Java code

@Entity@Table(name = "ibokee_report_comment")@Searchable@XmlRootElementpublic class ReportComment implements Serializable {    private static final long serialVersionUID = 1L;        private Long id;    /** 日志评论 */    private ArticleComment article;    /** 照片评论 */    private PhotoComment photo;    /** 微博评论 */    private PostComment post;    @Id    @GeneratedValue(strategy = GenerationType.AUTO)    @SearchableId    public Long getId() {        return id;    }    public void setId(Long id) {        this.id = id;    }    @ManyToOne(fetch = FetchType.EAGER)    @JoinColumn(name = "article")    public ArticleComment getArticle() {        return article;    }    public void setArticle(ArticleComment article) {        this.article = article;    }    @ManyToOne(fetch = FetchType.EAGER)    @JoinColumn(name = "photo")    public PhotoComment getPhoto() {        return photo;    }    public void setPhoto(PhotoComment photo) {        this.photo = photo;    }    @ManyToOne(fetch = FetchType.EAGER)    @JoinColumn(name = "post")    public PostComment getPost() {        return post;    }    public void setPost(PostComment post) {        this.post = post;    }}

Java code

@Entity@Table(name = "ibokee_wb_postcomment")@Searchable@XmlRootElementpublic class PostComment implements Serializable {    private static final long serialVersionUID = 1L;    private Integer id;    private Post post;    private User user;    private String content;    private Date createTime;    private Boolean del = Boolean.FALSE;    /** 评论回复 */    private PostComment parent;    public PostComment() {    }    @Id    @GeneratedValue(strategy = GenerationType.AUTO)    @SearchableId    public Integer getId() {        return id;    }    public void setId(Integer id) {        this.id = id;    }    @ManyToOne(fetch = FetchType.EAGER)    @JoinColumn(name = "post")    public Post getPost() {        return post;    }    public void setPost(Post post) {        this.post = post;    }    @ManyToOne(fetch = FetchType.EAGER)    @JoinColumn(name = "user")    public User getUser() {        return user;    }    public void setUser(User user) {        this.user = user;    }    @Column    public String getContent() {        return content;    }    public void setContent(String content) {        this.content = content;    }    @Column    public Date getCreateTime() {        return createTime;    }    public void setCreateTime(Date createTime) {        this.createTime = createTime;    }    @Column    public Boolean getDel() {        return del;    }    public void setDel(Boolean del) {        this.del = del;    }    @ManyToOne(fetch = FetchType.EAGER)    @JoinColumn(name = "parent")    public PostComment getParent() {        return parent;    }    public void setParent(PostComment parent) {        this.parent = parent;    }}

applicationContext-dao.xml
里sessionfactory配置错了

你打红字的不是问题关键，因为sessionfactory配置里的初始化方法错了，才导致你那红字的错误。
好好看下 applicationContext-dao.xml 怎么配置的。

没看出来哪里错了。。帮顶。
[解决办法]
楼主，你这代码的错误提示是加载完毕那个xml文件的时候就这样的错误，原因出在你的外键上,一定是你的数据不对，请楼主仔细查找一下数据！！
[解决办法]
帮顶 请高手指教
[解决办法]
是不是在主表里没有关联的数据啊
[解决办法]
ManyToOne()这里有问题,
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "post")


改改
@JoinColumn(name = "post" class="类名" column="外键ID")

不过LZ好象manyToOne和onetomany有点混淆,
[解决办法]
刘诗诗姑娘说的很有道理~
