To create a Java application that scrapes product details from an e-commerce website and stores the data in an SQLite database, you can follow these steps:

1. Install required libraries
2. Set up the SQLite database
3. Create a class to represent the Product
4. Scrape the e-commerce website using Jsoup
5. Store the scraped data into the SQLite database

Here's an example implementation of this application:

Step 1: Install required libraries

Add the following dependencies to your `pom.xml` file if you are using Maven:

```xml
<dependencies>
    <dependency>
        <groupId>org.jsoup</groupId>
        <artifactId>jsoup</artifactId>
        <version>1.14.3</version>
    </dependency>
    <dependency>
        <groupId>org.xerial</groupId>
        <artifactId>sqlite-jdbc</artifactId>
        <version>3.36.0.3</version>
    </dependency>
</dependencies>
```

Step 2: Set up the SQLite database

Create a new class called `DatabaseHelper.java` with the following content:

```java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

public class DatabaseHelper {

    private static final String DB_NAME = "products.db";
    private static final String CONNECTION_URL = "jdbc:sqlite:" + DB_NAME;

    public static Connection connect() {
        try {
            return DriverManager.getConnection(CONNECTION_URL);
        } catch (SQLException e) {
            System.out.println("Error connecting to the database");
            e.printStackTrace();
            return null;
        }
    }

    public static void setupDatabase() {
        try (Connection connection = connect()) {
            Statement statement = connection.createStatement();
            statement.execute("CREATE TABLE IF NOT EXISTS products (" +
                    "id INTEGER PRIMARY KEY AUTOINCREMENT," +
                    "name TEXT NOT NULL," +
                    "price REAL NOT NULL," +
                    "description TEXT" +
                    ")");
        } catch (SQLException e) {
            System.out.println("Error setting up the database");
            e.printStackTrace();
        }
    }
}
```

Step 3: Create a class to represent the Product

Create a new class called `Product.java` with the following content:

```java
public class Product {

    private String name;
    private double price;
    private String description;

    public Product(String name, double price, String description) {
        this.name = name;
        this.price = price;
        this.description = description;
    }

    // Getters and setters for each field

    @Override
    public String toString() {
        return "Product{" +
                "name='" + name + '\'' +
                ", price=" + price +
                ", description='" + description + '\'' +
                '}';
    }
}
```

Step 4: Scrape the e-commerce website using Jsoup

Create a new class called `Scraper.java` with the following content:

```java
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class Scraper {

    public static List<Product> scrapeProducts(String url) {
        List<Product> products = new ArrayList<>();

        try {
            Document document = Jsoup.connect(url).get();
            Elements productElements = document.select(".product"); // Replace with the appropriate CSS selector for your target website

            for (Element productElement : productElements) {
                String name = productElement.select(".product-name").text(); // Replace with the appropriate CSS selector for your target website
                double price = Double.parseDouble(productElement.select(".product-price").text().replace("$", "")); // Replace with the appropriate CSS selector for your target website
                String description = productElement.select(".product-description").text(); // Replace with the appropriate CSS selector for your target website

                products.add(new Product(name, price, description));
            }
        } catch (IOException e) {
            System.out.println("Error scraping the website");
            e.printStackTrace();
        }

        return products;
    }
}
```

Step 5: Store the scraped data into the SQLite database

Create a new class called `Main.java` with the following content:

```java
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.util.List;

public class Main {

    public static void main(String[] args) {
        DatabaseHelper.setupDatabase();

        List<Product> products = Scraper.scrapeProducts("https://example.com/products"); // Replace with the URL of the e-commerce website you want to scrape

        try (Connection connection = DatabaseHelper.connect()) {
            PreparedStatement preparedStatement = connection.prepareStatement("INSERT INTO products (name, price, description) VALUES (?, ?, ?)");

            for (Product product : products) {
                preparedStatement.setString(1, product.getName());
                preparedStatement.setDouble(2, product.getPrice());
                preparedStatement.setString(3, product.getDescription());

                preparedStatement.executeUpdate();
            }
        } catch (SQLException e) {
            System.out.println("Error inserting products into the database");
            e.printStackTrace();
        }
    }
}
```

Now, when you run the `main()` method in the `Main` class, it will scrape the product details from the specified e-commerce website and store them in an SQLite database. Note that you'll need to replace the example URL and CSS selectors with the ones corresponding to the actual e-commerce website you want to scrape.
전자 상거래 웹 사이트에서 제품 세부 정보를 스크랩하여 SQLite 데이터베이스에 데이터를 저장하는 Java 애플리케이션을 만들려면 다음 단계를 수행하면 됩니다.

1. 필요한 라이브러리 설치
2. SQLite 데이터베이스를 설정합니다
3. 제품을 나타내는 클래스를 생성합니다
4. Jsoup을 사용하여 전자상거래 웹사이트를 스크랩합니다
5. 스크랩한 데이터를 SQLite 데이터베이스에 저장

다음은 이 애플리케이션의 구현 예시입니다.

1단계: 필수 라이브러리 설치

Maven을 사용하는 경우 `pom.xml` 파일에 다음 종속성을 추가합니다:

```xml
<dependencies>
    <dependency>
        <groupId>org.jsoup</groupId>
        <artifactId>jsoup</artifactId>
        <version>1.14.3</version>
    </dependency>
    <dependency>
        <groupId>org.xerial</groupId>
        <artifactId>sqlite-jdbc</artifactId>
        <version>3.36.0.3</version>
    </dependency>
</dependencies>
```

2단계: SQLite 데이터베이스 설정

다음 내용으로 `DatabaseHelper.java`라는 새 클래스를 생성합니다:

```java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

public class DatabaseHelper {

    private static final String DB_NAME = "products.db";
    private static final String CONNECTION_URL = "jdbc:sqlite:" + DB_NAME;

    public static Connection connect() {
        try {
            return DriverManager.getConnection(CONNECTION_URL);
        } catch (SQLException e) {
            System.out.println("Error connecting to the database");
            e.printStackTrace();
            return null;
        }
    }

    public static void setupDatabase() {
        try (Connection connection = connect()) {
            Statement statement = connection.createStatement();
            statement.execute("CREATE TABLE IF NOT EXISTS products (" +
                    "id INTEGER PRIMARY KEY AUTOINCREMENT," +
                    "name TEXT NOT NULL," +
                    "price REAL NOT NULL," +
                    "description TEXT" +
                    ")");
        } catch (SQLException e) {
            System.out.println("Error setting up the database");
            e.printStackTrace();
        }
    }
}
```

3단계: Product를 나타내는 클래스 만들기

다음 내용으로 `Product.java`라는 새 클래스를 만듭니다:

```java
public class Product {

    private String name;
    private double price;
    private String description;

    public Product(String name, double price, String description) {
        this.name = name;
        this.price = price;
        this.description = description;
    }

    // Getters and setters for each field

    @Override
    public String toString() {
        return "Product{" +
                "name='" + name + '\'' +
                ", price=" + price +
                ", description='" + description + '\'' +
                '}';
    }
}
```

4단계: Jsoup

을 사용하여 이커머스 웹사이트 스크래핑하기다음 내용으로 `Scraper.java`라는 클래스를 새로 만듭니다:

```java
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class Scraper {

    public static List<Product> scrapeProducts(String url) {
        List<Product> products = new ArrayList<>();

        try {
            Document document = Jsoup.connect(url).get();
            Elements productElements = document.select(".product"); // Replace with the appropriate CSS selector for your target website

            for (Element productElement : productElements) {
                String name = productElement.select(".product-name").text(); // Replace with the appropriate CSS selector for your target website
                double price = Double.parseDouble(productElement.select(".product-price").text().replace("$", "")); // Replace with the appropriate CSS selector for your target website
                String description = productElement.select(".product-description").text(); // Replace with the appropriate CSS selector for your target website

                products.add(new Product(name, price, description));
            }
        } catch (IOException e) {
            System.out.println("Error scraping the website");
            e.printStackTrace();
        }

        return products;
    }
}
```

5단계: 스크랩한 데이터를 SQLite 데이터베이스에 저장

다음 내용으로 `Main.java`라는 새 클래스를 생성합니다:

```java
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.util.List;

public class Main {

    public static void main(String[] args) {
        DatabaseHelper.setupDatabase();

        List<Product> products = Scraper.scrapeProducts("https://example.com/products"); // Replace with the URL of the e-commerce website you want to scrape

        try (Connection connection = DatabaseHelper.connect()) {
            PreparedStatement preparedStatement = connection.prepareStatement("INSERT INTO products (name, price, description) VALUES (?, ?, ?)");

            for (Product product : products) {
                preparedStatement.setString(1, product.getName());
                preparedStatement.setDouble(2, product.getPrice());
                preparedStatement.setString(3, product.getDescription());

                preparedStatement.executeUpdate();
            }
        } catch (SQLException e) {
            System.out.println("Error inserting products into the database");
            e.printStackTrace();
        }
    }
}
```

이제 `Main` 클래스에서 `main()` 메서드를 실행하면 지정된 이커머스 웹사이트에서 제품 세부 정보를 스크랩하여 SQLite 데이터베이스에 저장합니다. 예제 URL과 CSS 선택기를 스크랩하려는 실제 이커머스 웹사이트에 해당하는 것으로 바꿔야 한다는 점에 유의하세요.
