RestTemplate uriVariables not expanded
提问by user1145874
I try to access a rest endpoint by using springs RestTemplate.getForObject() but my uri variables are not expanded, and attached as parameters to the url. This is what I got so far:
我尝试使用 springs RestTemplate.getForObject() 访问休息端点，但我的 uri 变量没有扩展，并作为参数附加到 url。这是我到目前为止得到的：
Map<String, String> uriParams = new HashMap<String, String>();
uriParams.put("method", "login");
uriParams.put("input_type", DATA_TYPE);
uriParams.put("response_type", DATA_TYPE);
uriParams.put("rest_data", rest_data.toString());
String responseString = template.getForObject(endpointUrl, String.class, uriParams);
the value of the endpointUrl Variable is http://127.0.0.1/service/v4_1/rest.phpand it's exactely what it's called but I'd expect http://127.0.0.1/service/v4_1/rest.php?method=login&input_type...to be called.
Any hints are appreciated.
endpointUrl 变量http://127.0.0.1/service/v4_1/rest.php的值正是它的名字，但我希望http://127.0.0.1/service/v4_1/rest.php?method=login&input_type...被调用。任何提示表示赞赏。
I'm using Spring 3.1.4.RELEASE

There is no append some query string logic in RestTemplateit basically replace variable like {foo}by their value:
没有附加一些查询字符串逻辑，RestTemplate它基本上用{foo}它们的值替换变量：
http://www.sample.com?foo={foo}
becomes:
变成：
http://www.sample.com?foo=2
if foois 2.
如果foo是 2。

The currently-marked answer from user180100 is technically correct but not very explicit. Here is a more explicit answer, to help those coming along behind me, because when I first read zhe's answer it didn't make sense to me.
来自 user180100 的当前标记答案在技术上是正确的，但不是很明确。这是一个更明确的答案，以帮助那些在我身后的人，因为当我第一次阅读 zhe 的答案时，这对我来说没有意义。
String url = "http://www.sample.com?foo={fooValue}";
Map<String, String> uriVariables = new HashMap();
uriVariables.put("fooValue", 2);
// "http://www.sample.com?foo=2"
restTemplate.getForObject(url, Object.class, uriVariables);
