Spring RestTemplate的“＃”字符编码

Question

I'm really having a tough time with some character encoding issues with "#". I'm trying to "GET" from a url "URL/path/#, with literally the "#" in front of the param. The endpoint is expecting the character encoded value for "#", or "%23". However, the RestTemplate is either a) not encoding "#" which results in other exceptions from the API (the API really wants "%23" and not "#", or b) double encoding the "%". How can I use the RestTemplate to literally send "%23".

The code is pretty simple:

restTemplate.exchange(url, HttpMethod.GET, httpEntityWithSomeAuthHeader, 
    new ParameterizedTypeReference<SomeObject>() {}); 

url is as described above...

Thanks!

Hope not to late ;)

try this one:

URI uri = new URI(url);
restTemplate.exchange(uri, HttpMethod.GET, httpEntityWithSomeAuthHeader, 
new ParameterizedTypeReference<SomeObject>() {}); 

And important, use %23 in url param. It's seems that if you use # (with string or uri) it discard all after... but with %23 and "new URI" it put in query (inside uri as %23) and the server decode as #.

Hope it's help ;)
