首先hibernate.cfg.xml

接下来是web.xml

再者是dwr.xml


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://www.getahead.ltd.uk/dwr/dwr20.dtd">

然后是测试类


package com.accp.test;
import java.util.List;
import org.hibernate.Transaction;
import com.accp.entity.Student;
import com.accp.entity.StudentDAO;
public class test {
/**
* @param args
*/
public int Mytest(){
StudentDAO stuDao=new StudentDAO();
try{
Student stu=new Student();
stu.setPassword("123");
stu.setAge(22);
stu.setUsername("chen");
Transaction tran=stuDao.getSession().beginTransaction();
stuDao.save(stu);
tran.commit();
return 1;
}catch(Exception ex){
ex.printStackTrace();
return 0;
}finally{
stuDao.getSession().close();
}
}
public List selList(){
StudentDAO stuDao=new StudentDAO();
try{
Transaction tra=stuDao.getSession().beginTransaction();
List<Student> list=stuDao.findAll();
return list;
}catch(Exception ex){
ex.printStackTrace();
return null;
}finally{
stuDao.getSession().close();
}
}
public static void main(String[] args) {
// TODO Auto-generated method stub
}
}
和JavaBean
package com.accp.entity;
/**
* Student generated by MyEclipse Persistence Tools
*/
public class Student implements java.io.Serializable {
// Fields
private Integer id;
private String username;
private String password;
private Integer age;
// Constructors
/** default constructor */
public Student() {
}
/** minimal constructor */
public Student(String username, String password) {
this.username = username;
this.password = password;
}
/** full constructor */
public Student(String username, String password, Integer age) {
this.username = username;
this.password = password;
this.age = age;
}
// Property accessors
public Integer getId() {
return this.id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUsername() {
return this.username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return this.password;
}
public void setPassword(String password) {
this.password = password;
}
public Integer getAge() {
return this.age;
}
public void setAge(Integer age) {
this.age = age;
}
}

最后是jsp页面的绑定
