了解hibernate注解的请进

[wwhui]

先贴上代码和错误信息：
1,hibernate.cfg.xml
<hibernate-configuration>
<session-factory>
<property name="hibernate.dialect">{hibernate.dialect}</property>
<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:test</property>
<property name="hibernate.connection.username">test</property>
<property name="hibernate.connection.password">123456</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<property name="hibernate.show_sql">true</property>
<property name="hibernate.format_sql">true</property>
<property name="hibernate.current_session_context_class">thread</property>

<mapping class="com.test.web.WoOrderTypeDao" />
</session-factory>
</hibernate-configuration>

2,WoOrderTypeDao.java
public class WoOrderTypeDao implements Serializable {

private static final long serialVersionUID = 8410470907542355038L;

/** 类型名称 */
public String orderTypeName;

/** 工单类型编码 */
public String orderTypeCode;

/** 工单类型ID */
public Long orderTypeId;

public void setOrderTypeName(String orderTypeName) {
this.orderTypeName = orderTypeName;
}

public void setOrderTypeCode(String orderTypeCode) {
this.orderTypeCode = orderTypeCode;
}

public void setOrderTypeId(Long orderTypeId) {
this.orderTypeId = orderTypeId;
}

@Column(name="ORDER_TYPE_NAME")
public String getOrderTypeName() {
return orderTypeName;
}

@Column(name="ORDER_TYPE_CODE")
public String getOrderTypeCode() {
return orderTypeCode;
}

@Id
@Column(name="ORDER_TYPE_ID")
public Long getOrderTypeId() {
return orderTypeId;
}

}

3,数据库操作
SessionFactory sessionFactory = new AnnotationConfiguration().buildSessionFactory();
Session session = sessionFactory.openSession();
session.beginTransaction();
Iterator ite = session.createQuery("from WoOrderTypeDao").iterate();

错误信息：
org.hibernate.hql.ast.QuerySyntaxException: WoOrderTypeDao is not mapped. [from WoOrderTypeDao]

我觉得错误出在数据库操作那里，但一直找不到解决的办法。
如果有知道的话，请大家告诉下。谢谢！！

<mapping resource="com/xxx/WoOrderType.hbm.xml"/>

你这工作差太多！慢慢干吧！

[Quote=引用 2 楼 APOLLO_TS 的回复:]

大哥 人家说了是注解的 你整个xxx.hbm.xml.....跟这没关系

多整整

[hanjin8307]

既然用注解
@Entity
@table(name="xxx")
这两个是不是应该写上啊??

[不能飞的肥燕]

少了“table”的注解。
呵呵

[oxcow]

@Entity
@Table(name = "hr_faq")
@SequenceGenerator(name = "seq_faq", sequenceName = "hr_faq_id")
public class Faq {
	/**
	 * 
	 */
	private static final long serialVersionUID = -769106584615139352L;

	private Long faqId; // 主键

	private int faqType;// 知识种类

	private String question; // 问题

	private String answer; // 答案

	// private Long operatorId; // 操作人ID

	private Date createDate; // 创建时间

	private Date updateDate; // 修改时间

	// 多对一
	private Operator operator;

	@ManyToOne(cascade = CascadeType.REFRESH, fetch = FetchType.LAZY)
	@JoinColumn(name = "operatorId", nullable = false)
	public Operator getOperator() {
		return operator;
	}

	public void setOperator(Operator operator) {
		this.operator = operator;
	}

	@Column(nullable = false)
	public String getAnswer() {
		return answer;
	}

	@Column(nullable = false)
	public Date getCreateDate() {
		return createDate;
	}

	@Column(nullable = false)
	public int getFaqType() {
		return faqType;
	}

	@Id
	@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "seq_faq")
	public Long getFaqId() {
		return faqId;
	}

	@Column(nullable = false)
	public String getQuestion() {
		return question;
	}

	@Column(nullable = false)
	public Date getUpdateDate() {
		return updateDate;
	}

	public void setAnswer(String answer) {
		this.answer = answer;
	}

	public void setCreateDate(Date createDate) {
		this.createDate = createDate;
	}

	public void setFaqType(int faqType) {
		this.faqType = faqType;
	}

	public void setFaqId(Long faqId) {
		this.faqId = faqId;
	}

	public void setQuestion(String question) {
		this.question = question;
	}

	public void setUpdateDate(Date updateDate) {
		this.updateDate = updateDate;
	}

<mapping class="test.Faq" />

学习中……，呵呵

[running_song]

看看EJB的 JPA，都是差不多的

非常感谢大家的帮助。
代码中是有TABLE的注解的，忘了贴出来了。不好意思。
哪位朋友可以例举一个针对Hibernate注解的数据操作的例子吗？
谢谢！

问题已解决，主要是因为工程导入的JAR包太多了，很多一样的，但是版本不一样。
后来重新建了一个工程，就可以啦。
感谢上面各位的回答。
谢谢！
