SpringBoot整合minio实现对象存储

(129条消息) SpringBoot整合minio实现对象存储_我哪会这个啊的博客-CSDN博客

 注：

一些代码自己做了些整改如下：

1.属性的读取：

@Data
@ConfigurationProperties(prefix = "piaoyou.minio")
public class MinioProperties {
    private String accessKey;
    private String secretKey;
    private String bucketName;
    private String endpoint;
}

 2.miniotemplate的代码（由mnioutils改造）：

package com.piaoyou.autoconfig.template;

import com.piaoyou.autoconfig.properties.MinioProperties;
import io.minio.*;

    }

    @Data
    public static class ObjectItem {
        private String objectName;
        private Long size;
    }
}

3. AutoConfiguration 自动配置类 的编写：

 

package com.piaoyou.autoconfig;

import com.piaoyou.autoconfig.properties.MinioProperties;
import com.piaoyou.autoconfig.properties.OssProperties;
import com.piaoyou.autoconfig.template.MinioTemplate;
import com.piaoyou.autoconfig.template.OssTemplate;
import io.minio.MinioClient;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;

@EnableConfigurationProperties({
        OssProperties.class,
        MinioProperties.class
})
public class PiaoyouAutoConfiguration {

    @Bean
    public OssTemplate ossTemplate(OssProperties ossProperties){
        return new OssTemplate(ossProperties);
    }

    @Bean
    public MinioClient minioClient(MinioProperties minioProperties){
        return  MinioClient.builder()
                .endpoint(minioProperties.getEndpoint())
                .credentials(minioProperties.getAccessKey(), minioProperties.getSecretKey())
                .build();
    }

    @Bean
    public MinioTemplate minioTemplate(MinioProperties minioProperties){
        return new MinioTemplate(minioProperties);
    }




}

 

 4.yml配置文件的编写：

piaoyou:
  minio:
    endpoint: http://******:9000
    accessKey: admin
    secretKey: admin
    bucketName: ****you
