Что такое альтернативность org.springframework.web.multipart.multipartresolver; ⇐ JAVA

[Anonymous]

I am upgrading spring-boot-starter-parent from version 2.5.3 to 3.0.0
I was using the org.springframework.web.multipart.commons.CommonsMultipartResolver; (extending it) for my file upload needs

Настройки размеров макс -загрузки. < /li>
Получение файлов params < /li>
Проверка вложений и т. Д. /> Пример кода: < /p>
public class MyMultipartResolver extends CommonsMultipartResolver {

private boolean resolveLazily = false;
private String supportedMimeTypes;

@Autowired
private SessionService sessionService;

@Autowired
private UserFileUploadEventService userFileUploadEventService;

@Value("${file.supportedMimeTypes}")
public void setSupportedMimeTypes(String value) {
supportedMimeTypes = value;
}

@Value("${upload.document.max.file.size}")
private int maxFileSize;

@Value("${scep.executable.path}")
private String scepExePath;

@Value("${upload.document.directory}")
private String uploadedDocumentPath;

public TamsMultipartResolver() {
super();
}

@Override

this.resolveLazily = resolveLazily;

MultipartParsingResult parsingResult = parseRequest(request);
validateAttachment(parsingResult.getMultipartFiles().getFirst("file"));

}
};
} else {
MultipartParsingResult parsingResult = parseRequest(request);
validateAttachment(parsingResult.getMultipartFiles().getFirst("file"));
return new DefaultMultipartHttpServletRequest(request, parsingResult.getMultipartFiles(), getSanitizedMultipartparameters(parsingResult),
parsingResult.getMultipartParameterContentTypes());

}
