常见实践

批量上传

在实际开发中，可能需要批量上传多个文件。可以使用循环来实现批量上传：

import org.jfrog.artifactory.client.Artifactory;
import org.jfrog.artifactory.client.ArtifactoryClientBuilder;

import java.io.FileInputStream;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.List;
import java.util.stream.Collectors;

public class ArtifactoryBatchUploadExample {
    public static void main(String[] args) throws IOException {
        String artifactoryUrl = "https://your-artifactory-url";
        String username = "your-username";
        String password = "your-password";
        String repositoryKey = "your-repository-key";
        String sourceDirectory = "path/to/source/directory";
        String targetDirectory = "target/path/in/artifactory";

        Artifactory artifactory = ArtifactoryClientBuilder.create()
               .setUrl(artifactoryUrl)
               .setUsername(username)
               .setPassword(password)
               .build();

        List<Path> files = Files.walk(Paths.get(sourceDirectory))
               .filter(Files::isRegularFile)
               .collect(Collectors.toList());

        for (Path file : files) {
            String targetPath = targetDirectory + "/" + file.getFileName().toString();
            FileInputStream fis = new FileInputStream(file.toFile());
            artifactory.repository(repositoryKey)
                   .upload(targetPath, fis)
                   .doUpload();
            fis.close();
        }

        System.out.println("Batch upload completed.");
    }
}

搜索工件

可以使用 Artifactory 的搜索 API 来查找满足特定条件的工件：

import org.jfrog.artifactory.client.Artifactory;
import org.jfrog.artifactory.client.ArtifactoryClientBuilder;
import org.jfrog.artifactory.client.model.FilesSearchResult;
import org.jfrog.artifactory.client.model.Item;

import java.util.List;

public class ArtifactorySearchExample {
    public static void main(String[] args) {
        String artifactoryUrl = "https://your-artifactory-url";
        String username = "your-username";
        String password = "your-password";
        String repositoryKey = "your-repository-key";
        String searchQuery = "name=*.jar";

        Artifactory artifactory = ArtifactoryClientBuilder.create()
               .setUrl(artifactoryUrl)
               .setUsername(username)
               .setPassword(password)
               .build();

        FilesSearchResult result = artifactory.searches()
               .itemsByProperty(repositoryKey, searchQuery)
               .doSearch();

        List<Item> items = result.getResults();
        for (Item item : items) {
            System.out.println("Found item: " + item.getUri());
        }
    }
}

最佳实践

错误处理

在使用 Java Artifactory Client 时，需要进行适当的错误处理。可以捕获可能的异常，并记录错误信息：

import org.jfrog.artifactory.client.Artifactory;
import org.jfrog.artifactory.client.ArtifactoryClientBuilder;

import java.io.FileInputStream;
import java.io.IOException;

public class ArtifactoryErrorHandlingExample {
    public static void main(String[] args) {
        String artifactoryUrl = "https://your-artifactory-url";
        String username = "your-username";
        String password = "your-password";
        String repositoryKey = "your-repository-key";
        String filePath = "path/to/your/file";
        String targetPath = "target/path/in/artifactory/file.txt";

        Artifactory artifactory = ArtifactoryClientBuilder.create()
               .setUrl(artifactoryUrl)
               .setUsername(username)
               .setPassword(password)
               .build();

        try (FileInputStream fis = new FileInputStream(filePath)) {
            artifactory.repository(repositoryKey)
                   .upload(targetPath, fis)
                   .doUpload();
            System.out.println("File uploaded successfully.");
        } catch (IOException e) {
            System.err.println("Error uploading file: " + e.getMessage());
        }
    }
}

资源管理

在使用文件流等资源时，要确保及时关闭资源，避免资源泄漏。可以使用 try-with-resources 语句来自动管理资源：

import org.jfrog.artifactory.client.Artifactory;
import org.jfrog.artifactory.client.ArtifactoryClientBuilder;

import java.io.FileInputStream;
import java.io.IOException;

public class ArtifactoryResourceManagementExample {
    public static void main(String[] args) {
        String artifactoryUrl = "https://your-artifactory-url";
        String username = "your-username";
        String password = "your-password";
        String repositoryKey = "your-repository-key";
        String filePath = "path/to/your/file";
        String targetPath = "target/path/in/artifactory/file.txt";

        Artifactory artifactory = ArtifactoryClientBuilder.create()
               .setUrl(artifactoryUrl)
               .setUsername(username)
               .setPassword(password)
               .build();

        try (FileInputStream fis = new FileInputStream(filePath)) {
            artifactory.repository(repositoryKey)
                   .upload(targetPath, fis)
                   .doUpload();
            System.out.println("File uploaded successfully.");
        } catch (IOException e) {
            System.err.println("Error uploading file: " + e.getMessage());
        }
    }
}

性能优化

在进行批量操作时，可以考虑使用多线程来提高性能。例如，使用 Java 的线程池来并行上传文件：

import org.jfrog.artifactory.client.Artifactory;
import org.jfrog.artifactory.client.ArtifactoryClientBuilder;

import java.io.FileInputStream;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.util.List;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.TimeUnit;
import java.util.stream.Collectors;

public class ArtifactoryPerformanceOptimizationExample {
    public static void main(String[] args) throws IOException, InterruptedException {
        String artifactoryUrl = "https://your-artifactory-url";
        String username = "your-username";
        String password = "your-password";
        String repositoryKey = "your-repository-key";
        String sourceDirectory = "path/to/source/directory";
        String targetDirectory = "target/path/in/artifactory";

        Artifactory artifactory = ArtifactoryClientBuilder.create()
               .setUrl(artifactoryUrl)
               .setUsername(username)
               .setPassword(password)
               .build();

        List<Path> files = Files.walk(Paths.get(sourceDirectory))
               .filter(Files::isRegularFile)
               .collect(Collectors.toList());

        ExecutorService executorService = Executors.newFixedThreadPool(5);

        for (Path file : files) {
            String targetPath = targetDirectory + "/" + file.getFileName().toString();
            executorService.submit(() -> {
                try (FileInputStream fis = new FileInputStream(file.toFile())) {
                    artifactory.repository(repositoryKey)
                           .upload(targetPath, fis)
                           .doUpload();
                    System.out.println("File uploaded: " + file.getFileName());
                } catch (IOException e) {
                    System.err.println("Error uploading file: " + e.getMessage());
                }
            });
        }

        executorService.shutdown();
        executorService.awaitTermination(1, TimeUnit.MINUTES);

        System.out.println("Batch upload completed.");
    }
}
