Spring AmazonS3 客户端序列化错误
Spring serialization error for AmazonS3 client
我遇到了一个我无法真正理解的奇怪问题。
我有一个代码可以使用 AmazonS3 客户端将文件上传到 AWS S3 存储桶。我有一个 try-catch 块，我在其中捕获任何异常，在 catch 块中，我抛出了我定义的异常，该异常由控制器方法 @ExceptionHandler 处理并且应该 return thymeleaf 模板 errorUpload.html.
@Service
public class UploadService {
private final AmazonS3 amazonS3;
private final String bucketName;
public UploadService(AmazonS3 amazonS3, @Value("${aws.bucketName}") String bucketName) {
this.amazonS3 = amazonS3;
this.bucketName = bucketName;
}
public void manualUpload(MultipartFile file) {
ObjectMetadata metadata = new ObjectMetadata();
metadata.setContentType(file.getContentType());
metadata.setContentLength(file.getSize());
try {
amazonS3.putObject(new PutObjectRequest(bucketName, file.getName(), file.getInputStream(), metadata));
} catch (Exception e) {
throw new UploadException(e.getMessage());
}
}
}
异常处理程序：
@ExceptionHandler({UploadException.class})
public String uploadError() {
return "errorPages/errorUpload";
}
当我在没有任何逻辑的情况下简单地在 manualUpload 方法中抛出异常时，它工作正常。但是，当使用 AmazonS3 对象并抛出异常时，逻辑会转到 ExceptionHandler，但会出现以下错误：
org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.Object] to type [byte[]] for value 'com.amazonaws.services.s3.AmazonS3Client@4b0ac28c'; nested exception is org.springframework.core.serializer.support.SerializationFailedException: Failed to serialize object using DefaultSerializer; nested exception is java.lang.IllegalArgumentException: DefaultSerializer requires a Serializable payload but received an object of type [com.amazonaws.services.s3.AmazonS3Client]

我认为这可能与将 SPRING_SECURITY_CONTEXT 存储在 spring_session_attributes table 中有关，因此由于 AmazonS3 未序列化，因此会引发该错误。知道如何解决这个问题吗？
错误确实很奇怪。在我看来，您正在为 Java (https://mvnrepository.com/artifact/com.amazonaws/aws-java-sdk-s3), so I would suggest you updating it to the new version (https://mvnrepository.com/artifact/software.amazon.awssdk/s3) 使用旧版本的 AWS SDK 并检查问题是否仍然存在。
有关更多详细信息，请查看有关如何迁移的 AWS 文档 https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/migration.html。
我找到了解决办法。
任何不可序列化的对象都不能创建为 bean 并使用，因为在这种情况下，当这个特定的 bean 将存储在 SPRING_SECURITY_CONTEXT 中时，会发生序列化异常。
因此，解决方案不是简单地创建 Bean，而是在我们想要使用它时使用“new”关键字创建对象。
@Service

private final String bucketName;
private final S3Client s3Client;
public UploadService(@Value("${aws.bucketName}") String bucketName,

this.s3Client = S3Client.builder()
.credentialsProvider(StaticCredentialsProvider.create(AwsBasicCredentials.create(awsAccessKey, awsSecretKey)))
.region(Region.US_EAST_1)

this.bucketName = bucketName;
