篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了jeecg-boot中上传图片到华为云obs云存储中相关的知识,希望对你有一定的参考价值。

大家好,我是雄雄,欢迎关注微信公众号:雄雄的小课堂。

前言

jeecg-boot框架中,其实对接的功能还是挺多的,其中就有文件云存储服务器,不过是阿里云oss的,那如果我们使用的是七牛云,或者华为云obs呢?我们需要改哪些内容才能实现上传obs的目的呢,今天我们就来看看如何使用jeecg-boot来实现将文件(图片)上传到华为云obs中。

配置nacos

因为我们用的是微服务版本,所以配置都在nacos中,如果是普通的boot版本的话,直接在yml文件中写配置就行。
nacos的配置如下:

  1. 找到jeecg节点,修改uploadType的值:
uploadType: hwobs

记住这个hwobs的值,我们需要在代码中声明一下它,相当于一个变量,这个值必须和代码中声明的那个变量的值一样,不然就找不到了。

  1. 添加obs节点:
  #华为云oss存储配置
  obs:
    endpoint: obs.cn-xxxxx-9.myhuaweicloud.com
    accessKey: KD6BYxxxxxx
    secretKey: Zv83xxxxxx
    bucketName: xxxxx
    staticDomain: xxxxx.obs.cn-xxxxxx-9.myhuaweicloud.com

注意:对应的值需要改成你自己的ak、sk等。

修改POM文件,添加华为云obs的依赖

添加代码如下:

<!--华为云OBS-->
		<dependency>
			<groupId>com.huaweicloud</groupId>
			<artifactId>esdk-obs-java</artifactId>
			<version>3.21.8</version>
			<exclusions>
				<exclusion>
					<groupId>com.squareup.okhttp3</groupId>
					<artifactId>okhttp</artifactId>
				</exclusion>
			</exclusions>
		</dependency>

新建OBS配置类

代码如下:


package org.jeecg.config.oss;

import org.jeecg.common.util.oss.ObsBootUtil;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**

@Configuration

    @Value("$jeecg.obs.endpoint")
    private String endpoint;
    @Value("$jeecg.obs.accessKey")
    private String accessKeyId;
    @Value("$jeecg.obs.secretKey")
    private String accessKeySecret;
    @Value("$jeecg.obs.bucketName")
    private String bucketName;


    @Bean
    public void initObsBootConfig() 
        ObsBootUtil.setEndPoint(endpoint);
        ObsBootUtil.setAccessKeyId(accessKeyId);
        ObsBootUtil.setAccessKeySecret(accessKeySecret);以上是关于jeecg-boot中上传图片到华为云obs云存储中的主要内容,如果未能解决你的问题,请参考以下文章
