1. Kiến thức cần có

• Căn bản về Oracle database, cách cài đặt cơ sở dữ liệu Oracle, công cụng SQL Developer, tạo database xem ở đây
• Lập trình Java Core
• HTML - CSS - JavaScript
• JSP và Servlet

2. Các bước tạo ứng dụng Spring Hibernate và thực hiện các thao tác CRUD

Bước 1: Tạo bảng và nhập dữ liệu

• Mở SQL Developer tạo bảng như hình dưới

 

Bước 2: Tạo Dynamic Web Project

• Khởi động Eclispe IDE -> vào menu File -> New -> Dynamic Web Project -> Nhập các thông số như hình dưới

• Tiếp tục kích vào Next -> Next -> Chọn Generate web.xml deyployment desciptor -> kích finish như hình

Bước 3: Convert sang Maven Project

• Kích chuột phải vào Project vừa tạo -> Configure -> Convert to Maven Project -> Finish

Bước 4: Khai báo các Maven Dependencies cần thiết

• Mở file pom.xml và cấu hình các Maven Dependencies gồm: spring web, web mvc, spring-orm, hibernate, jdbc oracle, servlet api, jstl

<!-- https://mvnrepository.com/artifact/javax.servlet/jstl -->

<dependency>

<groupId>javax.servlet</groupId>

<artifactId>jstl</artifactId>

<version>1.2</version>

</dependency>

<dependency>

<groupId>javax.servlet</groupId>

<artifactId>servlet-api</artifactId>

<version>2.5</version>

<scope>provided</scope>

</dependency>

<!--https://mvnrepository.com/artifact/org.springframework/spring-webmvc -->

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-webmvc</artifactId>

<version>5.3.18</version>

</dependency>

<!-- https://mvnrepository.com/artifact/org.springframework/spring-web -->

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-web</artifactId>

<version>5.3.18</version>

</dependency>

<!-- https://mvnrepository.com/artifact/org.springframework/spring-orm -->

<dependency>

<groupId>org.springframework</groupId>

<artifactId>spring-orm</artifactId>

<version>5.3.18</version>

</dependency>

<!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-core -->

<dependency>

<groupId>org.hibernate</groupId>

<artifactId>hibernate-core</artifactId>

<version>5.4.26.Final</version>

</dependency>

<!-- https://mvnrepository.com/artifact/com.oracle.database.jdbc/ojdbc10 -->

<dependency>

<groupId>com.oracle.database.jdbc</groupId>

<artifactId>ojdbc10</artifactId>

<version>19.20.0.0</version>

</dependency>

Bước 5: Cấu hình ứng dụng Spring Web Mvc

• Trong thư mục WEB-INF tạo thư mục views và tệp tin spring-servlet.xml như hình dưới

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns:p="http://www.springframework.org/schema/p"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:mvc="http://www.springframework.org/schema/mvc"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd

http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

 

<!-- chỉ ra các package chứa các lớp java được đăng ký như là các bean -->

<context:component-scan

base-package="controllers,dao" />

<!-- chỉ tìm kiếm các bean trong cùng context application mà nó được định nghĩa -->

<context:annotation-config />

<!-- mặc định các basic components được ủy quyền gửi request tới các controller -->

<mvc:annotation-driven />

 

<!-- cấu hình bean xác định view sẽ được sinh ra (thư mục chứa các view, đuôi tệp tin view) -->

<bean id="viewResolver"

class="org.springframework.web.servlet.view.InternalResourceViewResolver"

p:prefix="/WEB-INF/views/" p:suffix=".jsp" />

 

<!-- Tạo đối tượng bean dataSource kết nối database oracle -->

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">

<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver"></property>

<property name="url" value="jdbc:oracle:thin:@localhost:1521:bkap"></property>

<property name="username" value="system"></property>

<property name="password" value="1234$"></property>

</bean>

 

<!-- Tạo đối tượng bean sessionFactory cấu hình Hibernate -->

<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">

<property name="dataSource" ref="dataSource"></property>

<property name="packagesToScan" value="entities"></property>

<property name="hibernateProperties">

<props>

<prop key="hibernate.current_session_context_class">thread</prop>

<prop key="hibernate.show_sql">true</prop>

<prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>

</props>

</property>

</bean>

</beans>

• Mở tệp web.xml và cấu hình vào bên trong thẻ <web-app> như sau:

<!-- Cấu hình UTF-8 khi request hoặc response -->

<filter>

<filter-name>encodingFilter</filter-name>

<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

<init-param>

<param-name>encoding</param-name>

<param-value>UTF-8</param-value>

</init-param>

<init-param>

<param-name>forceEncoding</param-name>

<param-value>true</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>encodingFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

<!-- Cấu hình Spring MVC DispatcherServlet as front controller -->

<servlet>

<servlet-name>spring</servlet-name>

<servlet-class>

org.springframework.web.servlet.DispatcherServlet

</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/spring-servlet.xml</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>spring</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

Bước 6: Tạo các tệp tin theo cấu trúc mô tả sau

• Tạo gói entities với lớp Student

package entities;

import java.io.Serializable;

import java.util.Date;

import javax.persistence.Entity;

import javax.persistence.Id;

import javax.persistence.Table;

import javax.persistence.Temporal;

import javax.persistence.TemporalType;

 

import org.springframework.format.annotation.DateTimeFormat;

 

@Entity

@Table(name = "students")

public class Student implements Serializable {

 

// @Id

// @GeneratedValue(strategy = GenerationType.IDENTITY) //mã tự động tăng

// private int studentId;

@Id

private String studentId;

private String fullName;

private int gender;

@Temporal(TemporalType.DATE)

@DateTimeFormat(pattern = "dd/MM/yyyy")

private Date birthDay;

private String email;

private String phone;

private String address;

private int active;

 

public Student() {

// TODO Auto-generated constructor stub

}

 

public String getStudentId() {

return studentId;

}

 

public Student(String studentId, String fullName, int gender, Date birthDay, String email, String phone,

String address, int active) {

super();

this.studentId = studentId;

this.fullName = fullName;

this.gender = gender;

this.birthDay = birthDay;

this.email = email;

this.phone = phone;

this.address = address;

this.active = active;

}

 

public void setStudentId(String studentId) {

this.studentId = studentId;

}

 

public String getFullName() {

return fullName;

}

 

public void setFullName(String fullName) {

this.fullName = fullName;

}

 

public int getGender() {

return gender;

}

 

public void setGender(int gender) {

this.gender = gender;

}

 

public Date getBirthDay() {

return birthDay;

}

 

public void setBirthDay(Date birthDay) {

this.birthDay = birthDay;

}

 

public String getEmail() {

return email;

}

 

public void setEmail(String email) {

this.email = email;

}

 

public String getPhone() {

return phone;

}

 

public void setPhone(String phone) {

this.phone = phone;

}

 

public String getAddress() {

return address;

}

 

public void setAddress(String address) {

this.address = address;

}

 

public int getActive() {

return active;

}

 

public void setActive(int active) {

this.active = active;

}

}

• Tạo gói dao với lớp StudentDAO

package dao;

 

import java.util.List;

import javax.persistence.Query;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Repository;

import entities.Student;

 

@Repository

public class StudentDAO {

@Autowired

SessionFactory sessionFactory;

 

public StudentDAO() {

 

}

 

// Lấy tất cả sinh viên

public List<Student> getAll() {

Session session = sessionFactory.openSession();

List result = session.createQuery("from Student").getResultList();

return result;

}

 

// Tìm kiếm theo tên

public List<Student> search(String name) {

Session session = sessionFactory.openSession();

Query query = session.createQuery("from Student where fullName like :name");

query.setParameter("name", "%" + name + "%");

return query.getResultList();

}

 

// Insert sinh viên vào database

public void insert(Student student) {

Session session = sessionFactory.getCurrentSession();

session.beginTransaction();

session.save(student);

session.getTransaction().commit();

}

 

// Update lại thông tin sinh viên

public void update(Student student) {

Session session = sessionFactory.getCurrentSession();

session.beginTransaction();

session.update(student);

session.getTransaction().commit();

}

 

// Xóa sinh viên

public void delete(String id) {

Session session = sessionFactory.getCurrentSession();

session.beginTransaction();

var st = session.get(Student.class, id);

session.remove(st);

session.getTransaction().commit();

}

 

// Lấy sinh viên theo id

public Student getById(String id) {

Session session = sessionFactory.getCurrentSession();

session.beginTransaction();

Student st = session.get(Student.class, id);

session.getTransaction().commit();

return st;

}

}

• Tạo gói controllers với lớp StudentController

package controllers;

 

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.ModelAttribute;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RequestParam;

import dao.StudentDAO;

import entities.Student;

 

@Controller

public class StudentController {

@Autowired

StudentDAO studentDAO;

@RequestMapping(value= {"/","students"},method = RequestMethod.GET)

public String index(Model model) {

model.addAttribute("students",studentDAO.getAll());

return "index";

}

@RequestMapping(value= "addstudent",method = RequestMethod.GET)

public String create(Model model) {

var student=new Student();

model.addAttribute("student",student);

return "create";

}

@RequestMapping(value= "save",method = RequestMethod.POST)

public String save(@ModelAttribute("student") Student student, Model model) {

try {

studentDAO.insert(student);

}catch(Exception ex) {

model.addAttribute("error",ex.getMessage());

model.addAttribute("student",student);

return "create";

}

return "redirect:/students";

}

 

@RequestMapping(value= "edit",method = RequestMethod.GET)

public String edit(@RequestParam("id") String id,Model model) {

var student=studentDAO.getById(id);

model.addAttribute("student",student);

return "edit";

}

@RequestMapping(value= "update",method = RequestMethod.POST)

public String update(@ModelAttribute("student") Student student, Model model) {

try {

studentDAO.update(student);

}catch(Exception ex) {

model.addAttribute("error",ex.getMessage());

model.addAttribute("student",student);

return "create";

}

return "redirect:/students";

}

@RequestMapping(value= "search",method = RequestMethod.POST)

public String update(String searchname, Model model) {

model.addAttribute("students",studentDAO.search(searchname));

return "index";

}

@RequestMapping(value= "delete",method = RequestMethod.GET)

public String delete(@RequestParam("id") String id) {

studentDAO.delete(id);

return "redirect:/students";

}

}
