前言
上篇博客我们介绍了分布式云存储MinIO作业环境的搭建,以及分布式云储存MinIO在实际的文件服务中的优势。那么,今天我们就小试牛刀来将MinIO接入我们的微服务项目,实现一个分布式的文件服务器。
技术回顾
MinIO 提供高性能、与S3 兼容的对象存储系统,让你自己能够构建自己的私有云储存服务。
MinIO原生支持 Kubernetes,它可用于每个独立的公共云、每个 Kubernetes 发行版、私有云和边缘的对象存储套件。
MinIO是软件定义的,不需要购买其他任何硬件,在 GNU AGPL v3 下是 100% 开源的。
准备工作
申请accessKey\secretKey
MinIO控制台申请accessKey\secretKey
http://your_hostname:18001~18004/login minio/minio123
创建数据存储桶
创建数据存储桶
点击创建的桶我们进行访问策略配置
访问策略有private\custom\public
public 公共的桶,任何人都可以访问资源,直接映射为静态资源,可直接提供预览和下载
custom 自定义桶,用户根据自身需求定义访问规则
private 私有的桶,需要授权才能访问
根据一般的生产需求,我们定义一个private,一个custom桶。private保存私有资源,custom保存公共资源并禁止目录访问。
private 规则:
custom 规则:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Principal": {
"AWS": [
"*"
]
},
"Action": [
"s3:GetBucketLocation",
"s3:ListBucketMultipartUploads"
],
"Resource": [
"arn:aws:s3:::sacpublic"
]
},
{
"Effect": "Allow",
"Principal": {
"AWS": [
"*"
]
},
"Action": [
"s3:AbortMultipartUpload",
"s3:DeleteObject",
"s3:GetObject",
"s3:ListMultipartUploadParts",
"s3:PutObject"
],
"Resource": [
"arn:aws:s3:::sacpublic/*"
]
}
]
}

OkHttpSSLSocketClient兼容ssl
对于改解决方案一般生产环境都有固定的域名和匹配的ssl证书,如果也不用https我们代码则不用兼容ssl。但是如果我们配置了不可信任的ssl,这里我们则需要进行ssl兼容方案。
/**
* MinioConfig
* @author senfel
* @version 1.0
* @date 2023/9/14 11:37
*/
@Configuration
@ConditionalOnProperty(name = "oss.file.service", havingValue = "minio", matchIfMissing = true)
public class MinioConfig {
@Value("${minio.url}")
private String minioUrl;
@Value("${minio.accessKey}")
private String accessKey;
@Value("${minio.secretKey}")
private String secretKey;
@Bean
public MinioClient getMinioClient() {
OkHttpClient okHttpClient = new OkHttpClient.Builder()
.sslSocketFactory(OkHttpSSLSocketClient.getSSLSocketFactory(),OkHttpSSLSocketClient.getX509TrustManager()) // //通过sslSocketFactory方法设置https证书
.hostnameVerifier(OkHttpSSLSocketClient.getHostnameVerifier())
.build();
return MinioClient.builder().endpoint(minioUrl).httpClient(okHttpClient)
.credentials(accessKey, secretKey).build();
}
}
/**
* OkHttpSSLSocketClient
* @author senfel
* @version 1.0
* @date 2023/9/15 10:07
*/
public class OkHttpSSLSocketClient{
//获取SSLSocketFactory
public static SSLSocketFactory getSSLSocketFactory() {
try {
SSLContext sslContext = SSLContext.getInstance("SSL");
sslContext.init(null, getTrustManager(), new SecureRandom());
return sslContext.getSocketFactory();
} catch (Exception e) {
throw new RuntimeException(e);
}
}
//获取TrustManager
private static TrustManager[] getTrustManager() {
TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
@Override
public void checkClientTrusted(X509Certificate[] chain, String authType) {
}
@Override
public void checkServerTrusted(X509Certificate[] chain, String authType) {
}
@Override
public X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[]{};
}
}
};
return trustAllCerts;
}
//获取HostnameVerifier,验证主机名
public static HostnameVerifier getHostnameVerifier() {
HostnameVerifier hostnameVerifier = (s, sslSession) -> true;
return hostnameVerifier;
}
//X509TrustManager:证书信任器管理类
public static X509TrustManager getX509TrustManager() {
X509TrustManager x509TrustManager = new X509TrustManager() {
//检查客户端的证书是否可信
@Override
public void checkClientTrusted(X509Certificate[] chain, String authType) {
}
//检查服务器端的证书是否可信
@Override
public void checkServerTrusted(X509Certificate[] chain, String authType) {
}
@Override
public X509Certificate[] getAcceptedIssuers() {
return new X509Certificate[0];
}
};
return x509TrustManager;
}
}
静态资源预览解决方案
由于我们使用API上传,minio不能区分我们资源的类型,如果资源类型不对则不能正确提供预览功能,都直接变成为访问资源链接就下载了。
所以,在实际的项目集成中我们在上传资源前需要将资源类型写入请求中,方便minio解析并提供预览和下载功能。
/**
* 上传一个文件
*/
public ObjectWriteResponse uploadFile(InputStream stream, String bucket, String objectName) throws Exception {
String prefix = objectName.substring(objectName.lastIndexOf(".") + 1);
//静态资源预览解决方案
String contentType = ViewContentType.getContentType(prefix);
ObjectWriteResponse objectWriteResponse = minioClient.putObject(PutObjectArgs.builder().bucket(bucket).object(objectName)
.contentType(contentType)
.stream(stream, -1, 10485760).build());
return objectWriteResponse;
}
/**
* ViewContentType
* @author senfel
* @version 1.0
* @date 2023/9/14 17:27
*/
public enum ViewContentType {
DEFAULT("default","application/octet-stream"),
JPG("jpg", "image/jpeg"),
TIFF("tiff", "image/tiff"),
GIF("gif", "image/gif"),
JFIF("jfif", "image/jpeg"),
PNG("png", "image/png"),
TIF("tif", "image/tiff"),
ICO("ico", "image/x-icon"),
JPEG("jpeg", "image/jpeg"),
WBMP("wbmp", "image/vnd.wap.wbmp"),
FAX("fax", "image/fax"),
NET("net", "image/pnetvue"),
JPE("jpe", "image/jpeg"),
RP("rp", "image/vnd.rn-realpix");
private String prefix;
private String type;
public static String getContentType(String prefix){
if(StringUtils.isEmpty(prefix)){
return DEFAULT.getType();
}
prefix = prefix.substring(prefix.lastIndexOf(".") + 1);
for (ViewContentType value : ViewContentType.values()) {
if(prefix.equalsIgnoreCase(value.getPrefix())){
return value.getType();
}
}
return DEFAULT.getType();
}
ViewContentType(String prefix, String type) {
this.prefix = prefix;
this.type = type;
}
public String getPrefix() {
return prefix;
}
public String getType() {
return type;
}
}
资源上传预览测试
MinIO对于图片等资源可以直接预览,对于excel文档等直接提供下载功能
@SpringBootTest
@RunWith(SpringJUnit4ClassRunner.class)
public class CodeDbInfoServiceTests {
@Resource
@Lazy
private MinioUtil minioUtil;
/**
* upload
* @author senfel
* @date 2023/9/27 10:00
* @return void
*/
@Test
public void upload() throws Exception {
FileInputStream fileInputStream = new FileInputStream("C:/Users/dev/Desktop/minio.png");
ObjectWriteResponse sacprivate = minioUtil.uploadFile(fileInputStream, "sacprivate", "test/minio.png");
System.err.println(sacprivate.bucket());
}
/**
* 获取私库连接
* @author senfel
* @date 2023/9/27 10:01
* @return void
*/
@Test
public void getPrivateUrl() throws Exception{
String url = minioUtil.getPresignedObjectUrl("sacprivate", "test/minio.png", 60);
System.err.println(url);
}
}
测试结果
图片成功上传
私库直接预览访问失败
获取私库链接过期时间为60s
访问成功
60s后再次访问该链接,提示链接已经过期
至此minio接入并测试完成,对于公开桶的资源直接可任意访问不用获取有效期链接。文章来源:https://www.toymoban.com/news/detail-729506.html
写在最后
Springboot微服务接入MinIO实现文件服务较为简单,我们只要按照官方文档引入依赖调用即可。值得注意的是我们根据需求选择接入ssl兼容方案和静态资源预览功能。当然,minio的private\custom\public可以完全实现我们各种需求,可以完全替代市场上付费和笨重的分布式服务。文章来源地址https://www.toymoban.com/news/detail-729506.html
