- org.springframework.web.util.UriUtils

```
public abstract class UriUtils
extends Object
```
Utility class for URI encoding and decoding based on RFC 3986. Offers encoding methods for the various URI components.
All encode*(String, String) methods in this class operate in a similar way:
- Valid characters for the specific URI component as defined in RFC 3986 stay the same.
- All other characters are converted into one or more bytes in the given encoding scheme. Each of the resulting bytes is written as a hexadecimal string in the "%xy" format.
