用RestTemplate调取接口,取得返回数据,携带header,动态拼接url ,动态参数

记录我自己的工作

get 请求  ,携带 请求头 header (token)  

url 根据参数 动态拼接

参数   放入 map  动态拼接

private String lclUrl = "http://xxx.xxxx.com/lcl";

　　

private String TOKEN360FOB_URL = "http://xxx.xxxxxx.com/token?username={name}&password={password}";

　　

1 public JSONObject get360fobToken() {
2         String json = restTemplate.getForObject(TOKEN360FOB_URL, String.class, username, password);
3         JSONObject json1 = JSONObject.fromObject(json);
4         return json1;
5     }

62                 restTemplate.exchange(url, HttpMethod.GET, requestEntity, String.class, uriVariables);
63         String resBody = response.getBody();
64         JSONObject temp = JSONObject.fromObject(resBody);
65 
66 
67         return temp;
68     }

工作疑问:

可以用更简洁的方法 拼接 url 吗
