minio+springboot集成
当我们需要在Spring Boot项目中使用MinIO对象存储服务,并且需要支持文件分片上传时,可以按照以下步骤进行整合:
1. 添加MinIO和Spring Boot的依赖:在项目的pom.xml文件中添加MinIO和Spring Boot的依赖,例如:
```xml
<dependency>
<groupId>io.minio</groupId>
<artifactId>minio</artifactId>
<version>8.0.6</version>
</dependency>
```
2. 配置MinIO连接信息:在Spring Boot的配置文件(如application.properties或application.yml)中配置MinIO的连接信息,包括endpoint、accessKey和secretKey等,例如:
```yaml
minio:
endpoint: http://localhost:9000
access-key: your-access-key
secret-key: your-secret-key
```
3. 创建MinIO客户端:在Spring Boot的配置类中创建MinIO客户端的Bean,例如:
```java
@Configuration
public class MinioConfig {
@Value("${minio.endpoint}")
private String endpoint;
@Value("${minio.access-key}")
private String accessKey;
@Value("${minio.secret-key}")
private String secretKey;
@Bean
public MinioClient minioClient() {
return MinioClient.builder()
.endpoint(endpoint)
.credentials(accessKey, secretKey)
.build();
}
}
```
4. 实现文件分片上传:在业务逻辑中使用MinIO客户端进行文件分片上传,可以使用`putObject`方法将文件分片上传到MinIO服务器,例如:
```java
@Autowired
private MinioClient minioClient;
public void uploadFile(String bucketName, String objectName, InputStream inputStream, long size) throws Exception {
// 设置分片大小
long partSize = 5 * 1024 * 1024; // 5MB
// 初始化分片上传
CreateMultipartUploadResponse response = minioClient.createMultipartUpload(
CreateMultipartUploadArgs.builder()
.bucket(bucketName)
.object(objectName)
.build());
String uploadId = response.uploadId();
// 分片上传
int partNumber = 1;
long offset = 0;
while (offset < size) {
// 读取分片数据
byte[] data = new byte[(int) Math.min(partSize, size - offset)];
inputStream.read(data);
// 上传分片
UploadPartResponse uploadPartResponse = minioClient.uploadPart(
UploadPartArgs.builder()
.bucket(bucketName)
.object(objectName)
.uploadId(uploadId)
.partNumber(partNumber)
.stream(new ByteArrayInputStream(data), data.length, -1)
.build());
// 记录已上传的分片
Part part = Part.builder()
.partNumber(partNumber)
.eTag(uploadPartResponse.etag())
.build();
parts.add(part);
partNumber++;
offset += data.length;
}
// 完成分片上传
CompleteMultipartUploadResponse completeResponse = minioClient.completeMultipartUpload(
CompleteMultipartUploadArgs.builder()
.bucket(bucketName)
.object(objectName)
.uploadId(uploadId)
.parts(parts)
.build());
}
```
以上就是Spring Boot整合MinIO实现文件分片上传的基本步骤。在实际应用中,还可以根据需求进行更多的配置和处理,例如设置文件分片大小、处理上传进度等。
