1. Обзор приложения

В данной статье я покажу вам как создать веб приложение корзины (shopping cart) с Spring Boot, Hibernate и Thymeleaf.

Приложение основано на:

Eclipse 4.7 (Oxygen)
Spring Boot 2.x
Hibernate 5.x

Hibernate и JPA являются 2-мя похожими технологиями. Если вы знаете Hibernate вы можете легко работать с JPA и наоборот. Но JPA не так хорошо поддерживает пагинацию (Pagination). При этом пагинация это необходиме свойство в приложении, в этом Hibernate поддерживает лучше, имеено это причина почему я использую Hibernate для данного приложения.

2. Просмотр приложения

Функция покупки для пользователя и без требования входа в систему.

Функция для сотрудгиков и менеджеров:

Функция добавления и редактирования информации продукта (Только для менеджеров).

3. Приготовить базу данных

4. Создать проект Spring Boot

На Eclipse создать проект Spring Boot.

Ввести:

Name: SbHibernateShoppingCart
Group: org.o7planning
Description: Shopping Cart + Spring Boot + Hibernate + Thymeleaf
Package: org.o7plannng.sbshoppingcart

Выбрать технологии и библиотеки, которые будут использоваться:

Security
JPA
Thymeleaf
Web
MySQL
SQL Server
PosgreSQL

Так как данная статья является инструкцией, я выберу библиотеки для 4 типов баз данных это Oracle, My SQL, SQL Server, PostgreSQL. С Oracle мы объявим для нее библиотеку в следующем шаге (В части конфигурации pom.xml).

Когда вы выбираете JPA, он уже включает библиотеки JPA и Hibernate.

5. Конфигурация pom.xml

Если вы используете базу данных Oracle, вам нужно объявить необходимую библиотеку для Oracle в файле pom.xml:

** Oracle **

<dependencies>
    .....

     <dependency>
        <groupId>com.oracle</groupId>
        <artifactId>ojdbc6</artifactId>
        <version>11.2.0.3</version>
    </dependency>
    
    .....
</dependencies>

<repositories>
        ....

    <!-- Repository for ORACLE JDBC Driver -->
    <repository>
        <id>codelds</id>
        <url>https://code.lds.org/nexus/content/groups/main-repo</url>
    </repository>
    
    .....
</repositories>

Если вы подключаетесь к базе данных SQL Service, вы можете использовать одну из 2-х библиотек JTDS или Mssql-Jdbc:

** SQL Server **

<dependencies>
       .....

    <dependency>
        <groupId>com.microsoft.sqlserver</groupId>
        <artifactId>mssql-jdbc</artifactId>
        <scope>runtime</scope>
    </dependency>
    
    <dependency>
        <groupId>net.sourceforge.jtds</groupId>
        <artifactId>jtds</artifactId>
        <scope>runtime</scope>
    </dependency>

     .....
</dependencies>

Другие библиотеки:

<dependency>
    <groupId>org.thymeleaf.extras</groupId>
    <artifactId>thymeleaf-extras-springsecurity4</artifactId>
</dependency>

Примечание Spring Boot по умолчанию автоматически конфигурирует JPA, и создает Spring BEAN связанные с JPA, эти автоматические конфигурации Spring Boot включают:

DataSourceAutoConfiguration
DataSourceTransactionManagerAutoConfiguration
HibernateJpaAutoConfiguration

Цель данного приложения использовать Hibernate, поэтому нам нужно отключить автоматические конфигурации у Spring Boot.сказанные выше.

** SbHibernateShoppingCartApplication **

package org.o7planning.sbshoppingcart;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration;
import org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration;

@SpringBootApplication

@EnableAutoConfiguration(exclude = { //  
        DataSourceAutoConfiguration.class, //

public class SbHibernateShoppingCartApplication {

    public static void main(String[] args) {
        SpringApplication.run(SbHibernateShoppingCartApplication.class, args);
    }

    ........

}

После, конфигурировать необходимые Spring BEAN для Hibernate.

7. Безопасность и UserDetailsService

В данном приложении у нас есть 2 роли ROLE_MANAGER и ROLE_EMPLOYEE.

ROLE_EMPLOYEE: Данная роль для сотрудников, пользователь с данной ролью может смотреть список заказов, детали заказов, и смотреть их профайлы.
ROLE_MANAGER: Данная роль для менеджеров, пользователь с данной ролью может смотреть список заказов, детали заказов, и смотреть их профайлы, добавлять и редактировать продукт.
