Note: the components in the resulting builder will be

In addition please use build(boolean) with a value of "true" to
build the UriComponents instance in order to indicate that the
components are encoded.

variables to enable correct parsing:

public final UriComponentsBuilder encode()
In comparison to UriComponents.encode(), this method has the
same effect on the URI template, i.e. each URI component is encoded by
replacing non-ASCII and illegal (within the URI component type) characters
with escaped octets. However URI variables are encoded more strictly, by
also escaping characters with reserved meaning.
For most cases, this method is more likely to give the expected result
because in treats URI variables as opaque data to be fully encoded, while
UriComponents.encode() is useful only if intentionally expanding
URI variables that contain reserved characters.
For example ';' is legal in a path but has reserved meaning. This
method replaces ";" with "%3B" in URI variables but not in the URI
template. By contrast, UriComponents.encode() never replaces ";"
since it is a legal character in a path.

Effectively, a shortcut for building, encoding, and returning the String representation:
String uri = builder.build().encode().toUriString()
However if URI variables have been provided
then the URI template is pre-encoded separately from URI variables (see
encode() for details), i.e. equivalent to:
String uri = builder.encode().build().toUriString()

For the semantics of each component (i.e. set vs append) check the
builder methods on this class. For example host(String) sets
while path(String) appends.

UriBuilderThe given value is appended as-is without any checks for slashes other than to clean up duplicates. For example:
builder.path("/first-").path("value/").path("/{id}").build("123")
// Results is "/first-value/123"
By contrast UriBuilder.pathSegment(String...) builds the path from
individual path segments and in that case slashes are inserted transparently.
In some cases you may use a combination of both pathSegment and
path. For example:
builder.pathSegment("first-value", "second-value").path("/")
// Results is "/first-value/second-value/"
If a URI variable value contains slashes, whether those are encoded or
not depends on the configured encoding mode. See
encode(), or if using
UriComponentsBuilder via DefaultUriBuilderFactory
(e.g. WebClient or RestTemplate) see its
encodingMode property.
Also see the
URI Encoding section of the reference docs.

If slashes are present in a path segment, they are encoded:

// Results is "/ba%2Fz/a%2Fb"
To insert a trailing slash, use the UriBuilder.path(java.lang.String) builder method:

Note: encoding, if applied, will only encode characters
that are illegal in a query parameter name or value such as "="
or "&". All others that are legal as per syntax rules in
RFC 3986 are not
encoded. This includes "+" which sometimes needs to be encoded
to avoid its interpretation as an encoded space. Stricter encoding may
be applied by using a URI template variable along with stricter encoding
on variable values. For more details please read the
"URI Encoding"
section of the Spring Framework reference.

The provided variables may be a subset of all required ones. At build time, the available ones are expanded, while unresolved URI placeholders are left in place and can still be expanded later.
In contrast to UriComponents.expand(Map) or
buildAndExpand(Map), this method is useful when you need to
supply URI variables without building the UriComponents instance
just yet, or perhaps pre-expand some shared default values such as host
and port.
