生成pojo文件
package cn.lb.domain;

/**

*/
public class Employer implements java.io.Serializable {
// Fields
private long id;
private String name;

// Property accessors
public long getId() {

测试文件
package cn.lb.view;

Session session=sessionFactory.openSession();
Transaction transaction=null;
try {

emp.setName("申公豹Long");
emp.setHiredate(new Date());
transaction=session.beginTransaction();
//增
session.save(emp);
//查
//Emp emp2=(Emp) session.get(Emp.class, 2);
//System.out.println(emp.getUname());
//改
//Emp emp3=(Emp) session.load(Emp.class, 3);
//emp3.setUname("二郎神");
//删除
//Employer emp4=(Employer) session.load(Employer.class, 3);
//session.delete(emp4);
transaction.commit();
} catch (Exception e) {
if(transaction!=null){
transaction.rollback();
}
throw new RuntimeException(e.getMessage());
}finally{
if(session!=null &&session.isOpen()){
session.close();
}
}
}
}
oracle创建的数据库和索引，这里没有记录。
测试成功：
SQL> select * from employer;
