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*/@Entitypublic class Dept {/**部门编号*/private int deptNo;/**部门名称*/private String dName;/**部门地址*/private String loc;@Idpublic 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^^
