Springboot整合 Minio
Springboot整合 Minio
1、添加依赖
<dependency>
<groupId>io.miniogroupId>
<artifactId>minioartifactId>
<version>7.0.2version>
dependency>
2、添加配置
# 自定义配置项，方便在代码中使用
minio:
endpoint: 192.168.31.129
port: 9000
accessKey: admin
secretKey: 123456789
bucketName: car
3、添加工具类
配置类
@Data
@Configuration
/*加载yml文件中以minio开头的配置项*/
@ConfigurationProperties(prefix = "minio")
public class MinioConfig {
/*会自动的对应配置项中对应的key*/
private String endpoint;//minio.endpoint
private String accessKey;
private String secretKey;
private Integer port;
/*把官方提供的MinioClient客户端注册到IOC容器中*/
@Bean
public MinioClient getMinioClient() throws InvalidEndpointException, InvalidPortException {
MinioClient minioClient = new MinioClient(getEndpoint(), getPort(), getAccessKey(), getSecretKey(), false);
return minioClient;
}
}
工具类：
@Component
public class MinioClientUtil {
@Value("${minio.bucketName}")
private String bucketName;
@Autowired
private io.minio.MinioClient minioClient;
private static final int DEFAULT_EXPIRY_TIME = 7 * 24 * 3600;
/**
* 检查存储桶是否存在
*/
public boolean bucketExists(String bucketName) throws InvalidKeyException, ErrorResponseException,
IllegalArgumentException, InsufficientDataException, InternalException, InvalidBucketNameException,
InvalidResponseException, NoSuchAlgorithmException, XmlParserException, IOException {
boolean flag = minioClient.bucketExists(this.bucketName);
if (flag) return true;
return false;
}
/**
* 通过InputStream上传对象
*
* @param objectName 存储桶里的对象名称
* @param stream 要上传的流 (文件的流)
*/
public boolean putObject(String objectName, InputStream stream) throws Exception {
//判断 桶是否存在
boolean flag = bucketExists(bucketName);
if (flag) {
//往桶中添加数据 minioClient 进行添加
/**
* 参数1： 桶的名称
* 参数2： 文件的名称
* 参数3： 文件的流
* 参数4： 添加的配置
*/
minioClient.putObject(bucketName, objectName, stream, new PutObjectOptions(stream.available(), -1));
ObjectStat statObject = statObject(objectName);
if (statObject != null && statObject.length() > 0) {
return true;
}
}
return false;
}
/**
* 删除一个对象
* @param objectName 存储桶里的对象名称
*/
public boolean removeObject(String objectName)throws Exception {
boolean flag = bucketExists(bucketName);
if (flag) {
minioClient.removeObject(bucketName, objectName);
return true;
}
return false;
}
/**
* 删除指定桶的多个文件对象,返回删除错误的对象列表，全部删除成功，返回空列表
* @param objectNames 含有要删除的多个object名称的迭代器对象
*/
public List<String> removeObject(List<String> objectNames) throws Exception {
List<String> deleteErrorNames = new ArrayList<>();
boolean flag = bucketExists(bucketName);
if (flag) {
Iterable<Result<DeleteError>> results = minioClient.removeObjects(bucketName, objectNames);
for (Result<DeleteError> result : results) {
DeleteError error = result.get();
deleteErrorNames.add(error.objectName());
}
}
return deleteErrorNames;
}
/**
* 获取对象的元数据
* @param objectName 存储桶里的对象名称
*/
public ObjectStat statObject(String objectName) throws Exception {
boolean flag = bucketExists(bucketName);
if (flag) {
ObjectStat statObject = minioClient.statObject(bucketName, objectName);
return statObject;
}
return null;
}
/**
* 文件访问路径
* @param objectName 存储桶里的对象名称
*/
public String getObjectUrl(String objectName) throws Exception {
boolean flag = bucketExists(bucketName);
String url = "";
if (flag) {
url = minioClient.getObjectUrl(bucketName, objectName);
}
return url;
}
}
4、controller中的使用
@Autowired
private MinioClientUtil minioClientUtil;
@PostMapping("/img")
public Result uploadMinio(@RequestPart MultipartFile file) throws Exception {
//拿到图片 MultipartFile封装接受的类
//拿到图片的名称
String filename = file.getOriginalFilename();
//拿到图片的 UUId + 图片类型 (解决图片重名的问题 )
String uuid = UUID.randomUUID().toString();
String imgType = filename.substring(filename.lastIndexOf("."));
//图片文件的新名称 xxx/uuid.jpg 图片拼接后的名
String fileName = uuid + imgType;
boolean flag = minioClientUtil.putObject(fileName, file.getInputStream());
String path = "http://192.168.31.129:9000/car/" + fileName;
return flag ? Result.ok("上传成功",path):Result.fail("图片删除失败");
}
5、前端的组件
1、添加样式
2、添加组件
<el-dialog title="车辆类型添加" :visible.sync="dialogFormADDVisible">
<el-form :model="addCarType">
<el-form-item label="车辆类型名称" label-width="240px">
<el-input v-model="addCarType.typeName" autocomplete="off">el-input>
el-form-item>
<el-form-item label="车辆公司" label-width="240px">
<el-input v-model="carType.company" autocomplete="off">el-input>
el-form-item>
<el-form-item label="汽车图片" label-width="240px">
<el-upload
class="avatar-uploader"
action="http://localhost:9000/img"
:show-file-list="false"
:on-success="handleAvatarSuccess">
<img v-if="imageUrl" :src="imageUrl" class="avatar">
<i v-else class="el-icon-plus avatar-uploader-icon">i>
el-upload>
el-form-item>
<el-form-item label="备注" label-width="240px">
<el-input v-model="addCarType.remarks" autocomplete="off">el-input>
el-form-item>
el-form>
<div slot="footer" class="dialog-footer">
<el-button @click="dialogFormADDVisible = false">取 消el-button>
<el-button type="primary" @click="commitADDCarType">确 定el-button>
div>
el-dialog>
3、添加js
//图片上传成功的执行的函数
handleAvatarSuccess(resp, file){
console.log(resp)
console.log(resp.data);
//上传成功的图片回显
this.imageUrl = resp.data;
},
//添加显示
showAddDialog(){
this.dialogFormADDVisible = true;
}
