5、domain和hbm.xml配置

package cn.itcast.springmvc.domain;

public class Person {

 private String id;
 private String name;
 private Integer age;
 private String address;
 public String getId() {
  return id;
 }

 }
 public void setName(String name) {
  this.name = name;
 }
 public Integer getAge() {
  return age;
 }
 public void setAge(Integer age) {
  this.age = age;
 }
 public String getAddress() {
  return address;
 }
 public void setAddress(String address) {
  this.address = address;
 }
}

----------------------------

Person.hbm.xml

public interface IPersonDao {
 public Person findPersonById(String id);
 public List<Person> findAllPerson();
 public void savePerson(Person p);
 public void deletePersonById(String id);
 public void updatePerson(Person p);
}

7、PersonDaoImpl
