Dept.java（实体类）

package com.web.entities;

import javax.persistence.Entity;
import javax.persistence.Id;

/**部门实体 @Table(name = "DEPT")可省略*/
@Entity
public class Dept {
	/**部门编号*/
	private int deptNo;
	/**部门名称*/
	private String dName;
	/**部门地址*/
	private String loc;

	@Id
	public int getDeptNo() {
		return deptNo;
	}

	public void setDeptNo(int deptNo) {
		this.deptNo = deptNo;
	}

	public String getdName() {
		return dName;
	}

	public void setdName(String dName) {
		this.dName = dName;
	}

	public String getLoc() {
		return loc;
	}

	public void setLoc(String loc) {
		this.loc = loc;
	}

}

DeptTest.java（测试类）

package com.lhfc.test;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.AnnotationConfiguration;

import com.web.entities.Dept;

/**部门实体测试*/
public class DeptTest {

	public static void main(String[] args) {
		Dept dept = new Dept();
		dept.setDeptNo(12);
		dept.setdName("锦衣卫");
		dept.setLoc("火焰山A洞B座");

		//		SessionFactory sessionFactory = new AnnotationConfiguration().addPackage("com.web.entities")
		//				.addAnnotatedClass(Dept.class).configure().buildSessionFactory();

		SessionFactory sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();

		Session session = sessionFactory.openSession();

		Transaction transaction = session.beginTransaction();
		session.save(dept);
		transaction.commit();
		session.close();
	}
}

重点是使用了AnnotationConfiguration。测试代码中注释部分是使用annotations的另外一种方法^^数据库表请各位兄弟参照我的实体类写^^
