hibernate簡單程式，實現從頁面對資料庫的增刪改查（主從表關聯）
阿新 • • 發佈：2019-01-28
前段時期一直使用三層來寫從頁面對資料庫的增刪改查，今天用hibernate框架來實現從頁面對資料庫的增刪改查，
首先介紹下今天我們要實現的功能，
1、使用者能夠註冊，2、註冊成功後直接跳到登入頁面，3、登入成功後直接跳到對公司、人員的增刪改查，
4、要有對人員介面的分頁功能
一、首先看下檔案的目錄
unity裡面寫的是配置檔案的session介面工具，dao層就是各種增刪改查的方法
1、首先得配置檔案：hibernate.cfg.xml
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory >
<!-- 配置資料庫連線資訊 -->
<property name="connection.driver_class">
com.mysql.jdbc.Driver
</property>
<property name="connection.url">
jdbc:mysql://localhost:3306/company
</property>
<property name="connection.username">
root
</property>
<property name="connection.password">
DCX5201314
</property>
<!-- 資料庫方言-->
<property name="dialect">
org.hibernate.dialect.MySQL5Dialect
</property>
<!-- 非必要的 -->
<property name="hbm2ddl.auto">update</property><!-- 可以反向生成表 -->
<!-- 對映配置檔案 -->
<mapping resource="entity/user.hbm.xml"/>
<mapping resource="entity/bm.hbm.xml"/>
<mapping resource="entity/ry.hbm.xml"/>
</session-factory>
</hibernate-configuration> package unity;
public class unitl {
public Session lj(){
//新建Configuration物件
Configuration cfg=new Configuration().configure();
//通過Configuration建立SessionFactory物件
ServiceRegistry registry = new StandardServiceRegistryBuilder()
.applySettings(cfg.getProperties())
.build();
SessionFactory sf = cfg.buildSessionFactory(registry);
//建立session
Session session=sf.openSession();
return session;
}
} 3、首先我們先寫使用者的註冊、登入
配置檔案：user.hbm.xml
<hibernate-mapping >
<class name="entity.user" table="user" >
<id name="id" >
<!-- 設定主鍵 -->
<generator class="native"></generator>
</id>
<property name="name" />
<property name="pwd" />
</class>
</hibernate-mapping> package entity;
public class user {
private int id;
private String name;
private String pwd;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPwd() {
return pwd;
}
public void setPwd(String pwd) {
this.pwd = pwd;
}
}
public class Userzhuceservlet extends HttpServlet {
dao.selectone se=new dao.selectone();
public Userzhuceservlet() {
super();
}
public void destroy() {
super.destroy(); // Just puts "destroy" string in log
// Put your code here
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
response.setContentType("text/html;charset=utf-8");
PrintWriter out = response.getWriter();
this.doPost(request, response);
out.flush();
out.close();
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
response.setContentType("text/html;charset=utf-8");
PrintWriter out = response.getWriter();
//用type接受頁面的值
String type=request.getParameter("type");
if ("1".equals(type)) {
System.out.println("haha");
//呼叫條件查詢的方法
zhuce(request, response);
}
else if ("2".equals(type)) {
login(request, response);
}
out.flush();
out.close();
}
/*************註冊********************************************/
public void zhuce(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String name=request.getParameter("name");
String pwd=request.getParameter("pwd");
int a=se.selllt(name,pwd);
if (a>0) {
response.sendRedirect("login.jsp");
}
}
/*************登入********************************************/
public void login(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String name=request.getParameter("name");
String pwd=request.getParameter("pwd");
int a=se.login(name,pwd);
if (a>0) {
System.out.println("登入成功");
response.sendRedirect("index.jsp");
}else {
System.out.println("登入失敗");
}
}
public void init() throws ServletException {
// Put your code here
}
}public class selectone {
//呼叫工具包
static unitl unitl=new unitl();
static Session session=unitl.lj();
/****************註冊************************************/
public int selllt(String name,String pwd){
int a=0;
//3、開啟事務
Transaction ts=session.beginTransaction();
//執行資料庫操作
//新增操作
user u=new user();
u.setName(name);
u.setPwd(pwd);
session.save(u);
System.out.println("註冊成功");
//提交
ts.commit();
//關閉session
//session.close();
a=1;
return a;
}
/****************登入************************************/
public int login(String name,String pwd){
//執行資料庫操作
//編寫hql
String hql="select name from user where name=? and pwd=?";
List<String> list=session.createQuery(hql)
.setString(0, name)
.setString(1, pwd)
.list();
int a=list.size();
System.out.println(list.size());
// for(String na:list){
// System.out.println(na+"=====");
// }
//關閉session
//session.close();
return a;
}
}<body>
