Hibernate3在Eclipse下web工程中的基本配置

• 获得Hibernate3组件包，获得渠道可参考http://kch.iteye.com/category/85145
• 将Hibernate3组件包根目录下的Hibernate3.jar和lib目录下所有.jar文件拷贝到web工程的WEB-INF/lib目录中
• 在Hibernate3组件包中找到etc目录，可参考hibernate.cfg.xml文件配置自己所用的hibernate.cfg.xml文件，例如：

<?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">
	<!-- Hibernate配置文件 -->
<hibernate-configuration>
	<!-- 会话工厂配置 -->
	<session-factory>
		<!-- 数据库驱动程序 -->
		<property name="connection.driver_class">
			oracle.jdbc.driver.OracleDriver
	</property>
		<!-- 数据库连接字符串，1521：后为数据库名 -->
		<property name="connection.url">
			jdbc:oracle:thin:@localhost:1521:DBNAME
	</property>
		<!-- 数据库登录名 -->
		<property name="connection.username">SCOTT</property>
		<!-- 数据库登录密码 -->
		<property name="connection.password">TIGER</property>
		<!-- 数据库方言 ，ORACLE9\10\11都用Oracle9iDialect-->
		<property name="dialect">
			org.hibernate.dialect.OracleDialect
	</property>
		<!-- 是否显示SQL语句 -->
		<property name="show_sql">true</property>
		<property name="format_sql">true</property>
		<property name="current_session_context_class">thread</property>
		<!-- 每次提交数据的数量，设置此项可提高运行效率 -->
		<property name="hibernate.jdbc.batch_size">100</property>
		<property name="hibernate.cache.provider_class">org.hibernate.cache.HashtableCacheProvider</property>
		<!-- POJO对象对应的映射文件 -->
		<mapping resource="cn/kch/pojo/users.hbm.xml" />
	</session-factory>
</hibernate-configuration>

•  POJO对象对应的映射文件可参考users.hbm.xml文件，如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
	<class name="cn.kch.pojo.users" table="USERS">
		<id name="id" type="java.lang.Integer">
			<column name="ID" />
			<generator class="sequence">
				<param name="sequence">gb_seq</param>
			</generator>
		</id>
		<property name="username" type="java.lang.String" not-null="true">
			<column name="NAME" />
		</property>
		<property name="password" type="java.lang.String" not-null="true">
			<column name="PASSWORD" />
		</property>
		<property name="email" type="java.lang.String" not-null="true">
			<column name="EMAIL" />
		</property>
		<property name="name" type="java.lang.String">
			<column name="NAME" />
		</property>
		<property name="sex" type="java.lang.String">
			<column name="SEX" />
		</property>
		<property name="cellphone" type="java.lang.String">
			<column name="CELLPHONE" />
		</property>
		<property name="telephone" type="java.lang.String">
			<column name="TELEPHONE" />
		</property>
		<property name="organization" type="java.lang.String">
			<column name="ORGANIZATION" />
		</property>
		<property name="department" type="java.lang.String" not-null="true">
			<column name="DEPARTMENT" />
		</property>
		<property name="post" type="java.lang.String">
			<column name="POST" />
		</property>
		<property name="role" type="java.lang.String">
			<column name="ROLE" />
		</property>
		<property name="createdTime" type="java.util.Date" not-null="true">
			<column name="CREATED_TIME" />
		</property>
		<property name="lastEntryTime" type="java.util.Date" not-null="true">
			<column name="LAST_ENTRY_TIME" />
		</property>
		<property name="activation" type="java.lang.String">
			<column name="ACTIOVATION" />
		</property>
	</class>
</hibernate-mapping>

•  POJO对象的类文件可参考users.java文件，如下：

package cn.kch.pojo;

import java.util.Date;

public class users implements java.io.Serializable {

	/**
	 * user POJO class
	 */
	private static final long serialVersionUID = -4671554435704824992L;
	
	private int id; // 序号
	private String username; // 用户名
	private String password; // 密码
	private String email; // 电子邮箱
	private String name; // 姓名
	private String sex; // 性别
	private String cellphone; // 移动电话
	private String telephone; // 固定电话
	private String organization; // 所在单位
	private String department; // 所在部门
	private String post; // 所处职位
	private String role; // 所属角色
	private Date registerTime; // 注册时间
	private Date lastEntryTime; // 最后登录时间
	private String activation; // 是否激活

	public users() {
	}

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

	public int getId() {
		return id;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public String getUsername() {
		return username;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public String getPassword() {
		return password;
	}

	public void setEmail(String email) {
		this.email = email;
	}

	public String getEmail() {
		return email;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getName() {
		return name;
	}

	public void setSex(String sex) {
		this.sex = sex;
	}

	public String getSex() {
		return sex;
	}

	public void setCellphone(String cellphone) {
		this.cellphone = cellphone;
	}

	public String getCellphone() {
		return cellphone;
	}

	public void setTelephone(String telephone) {
		this.telephone = telephone;
	}

	public String getTelephone() {
		return telephone;
	}

	public void setOrganization(String organization) {
		this.organization = organization;
	}

	public String getOrganization() {
		return organization;
	}

	public void setDepartment(String department) {
		this.department = department;
	}

	public String getDepartment() {
		return department;
	}

	public void setPost(String post) {
		this.post = post;
	}

	public String getPost() {
		return post;
	}

	public void setRole(String role) {
		this.role = role;
	}

	public String getRole() {
		return role;
	}

	public void setRegisterTime(Date registerTime) {
		this.registerTime = registerTime;
	}

	public Date getRegisterTime() {
		return registerTime;
	}

	public void setLastEntryTime(Date lastEntryTime) {
		this.lastEntryTime = lastEntryTime;
	}

	public Date getLastEntryTime() {
		return lastEntryTime;
	}

	public void setActivation(String activation) {
		this.activation = activation;
	}

	public String getActivation() {
		return activation;
	}
}

•  至此Hibernate3在Eclipse下web工程的基本配置完毕

将Hibernate3组件包根目录下的Hibernate3.jar和lib目录下所有.jar文件拷贝到web工程的WEB-INF/lib目录中

被包的问题搞晕了 ，不知道为什么一定要考过来才可以，通过Eclipse引入的方式指定
老会提示
   Configuration cfg = new Configuration().configure();不能初始化
