Step 8. Set up MinIO Java SDK


Add the MinIO Java SDK dependency to your pom.xml:
<!-- MinIO dependency -->
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>8.2.2</version>
</dependency>

Step 9. Configure MinioConfig.java File


package com.example.fileupload.config;
import io.minio.MinioClient;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class MinioConfig {
@Value("${minio.url}")
private String minioUrl;
@Value("${minio.accessKey}")
private String accessKey;
@Value("${minio.secretKey}")
private String secretKey;
@Bean
public MinioClient minioClient() {
return MinioClient.builder()
.endpoint(minioUrl)
.credentials(accessKey, secretKey)
.build();
}
}

Step 10. Upload Files in java Controller


@Autowired
private MinioClient minioClient;
@Value("${minio.bucketName}")
private String bucketName;
public String uploadFile(@RequestParam("file") MultipartFile file) {
try {
String fileName = file.getOriginalFilename();
minioClient.putObject(
PutObjectArgs.builder()
.bucket(bucketName)
.object(fileName)
.stream(file.getInputStream(), file.getSize(), -1)
.contentType(file.getContentType())
.build()
);
return fileName;
} catch (MinioException | IOException e) {
throw new RuntimeException("Error occurred while uploading file to MinIO", e);
}
}

Step 11. View the Uploaded File in Minio Bucket

  • Verify File Upload: After uploading a file using your Laravel application, verify that it appears in your Minio bucket.
