在Spring Boot项目中集成AWS SDK,可以实现与AWS S3的连接并实现文件的上传和下载功能。
首先,需要在pom.xml文件中添加AWS SDK的依赖项,并确保version保持一致。在dependencyManagement中添加以下代码:
```
<dependencyManagement>
<dependencies>
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>bom</artifactId>
<version>2.0.0-preview-12</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
```
然后,在dependencies中添加以下代码:
```
<dependency>
<groupId>software.amazon.awssdk</groupId>
<artifactId>s3</artifactId>
<version>2.0.0-preview-12</version>
</dependency>
```
接下来,在application.properties文件中进行配置,包括AWS的访问密钥、S3存储桶名称、存储桶所在地区以及上传文件的路径:
```
aws.access_key_id=your access key
aws.secret_access_key=your secret access key
aws.s3.bucket=your bucket name
aws.s3.region=cn-northwest-1
aws.s3.filename=/666666/test123/photo.zip
```
在文件上传和下载的方法中,需要注意传递给方法的key参数是指存储在AWS S3上的文件名。如果key参数是路径字符串格式,S3服务器会自动创建对应路径的文件夹。例如,如果在application.properties中设置了aws.s3.filename=/666666/test123/photo.zip,那么key参数为/666666/test123/photo.zip,S3存储桶下就会有一个名为/666666/test123/photo.zip的文件,即上传的文件。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
