replace deprecated org.springframework.util.Base64Utils with Base64

[ZeeD]

Description

The resttemplate module relies on spring Base64Utils. But latest version of the framework have deprecated it, suggesting to use Base64 from the stdlib.

I'm using the latest version from brew.

Swagger´s resttemplate module is not compatible with the newest spring boot version, because the depricated issue has been removed by spring.

[The-Arne]

The swagger code generator is currently incompatible with spring, at least for APIs that use basic auth. Is there a reason the merge request that fixes the problem sits ignored for almost a year now? Do you need another merge request? Are there any problems with the existing one? Or is the project just dead and nothing happens anymore, apart from some automated dependency updates?

Hi @frantuma

Can you look at related pull requests (https://github.com/swagger-api/swagger-codegen-generators/pull/1117). This issue blocks the upgrade to spring-boot 3.4.x

[The-Arne]

For anyone else running into this problem: We switched to https://github.com/OpenAPITools/openapi-generator/. This worked well, necessary code changes were minimal. And it's compatible with current spring-core.

[joernfechner]

Any updates or is the only way to fix this problem to switch on OpenAPI?

[chrlembeck]

Trapped into same problem today. Can you please fix this incompatibility?

3.5.0 of spring boot has this issue too. Can we get the PR merged?

[ykartsev]

Voting for this issue as well. It prevents from updating to Spring Boot 3.4.x and above.

[dmitry-weirdo]

Any updates on this? I can't update to the newer Spring Boot since org.springframework.util.Base64Utils was removed from it.

[chrlembeck]

As a workaround you can write your own Base64Utils class an put it into the package org.springframework.util in your own project.

package org.springframework.util;

import java.util.Base64;

@Deprecated(forRemoval = true)
public class Base64Utils {

  @Deprecated(forRemoval = true)
  public static String encodeToString(final byte[] bytes) {
    return Base64.getEncoder().encodeToString(bytes);
  }
}

Same issue for me
