restTemplate发送POST请求时可以通过restTemplate.postForObject(url.toString(),requestEntity,String.
class
)
方式请求，但是GET却没有相应的方法，但是可以使用exchange替代，代码如下：
HttpHeaders headers 
= 
new
 HttpHeaders();
headers.add(
"token"
,token);
HttpEntity
<String> requestEntity = 
new
 HttpEntity<>(
null
, headers);
ResponseEntity
<String> resEntity = restTemplate.exchange(url.toString(), HttpMethod.GET, requestEntity, String.
class
);

@ApiModel
public
class
 CommonResult<T>
 {
    @ApiModelProperty(value 
= "状态码"
)
    
private
 Integer code;
    @ApiModelProperty(value 
= "信息"
)
    
private
 String msg;
    
private
 T data;

    
public
 Integer getCode() {
        
return
 code;
    }

    
public
void
 setCode(Integer code) {
        
this
.code =
 code;
    }

    
public
 String getMsg() {
        
return
 msg;
    }

    
public
void
 setMsg(String msg) {
        
this
.msg =
 msg;
    }

    
public
 T getData() {
        
return
 data;
    }

    
public
void
 setData(T data) {
        
this
.data =
 data;
    }

    @Override
    
public
 String toString() {
        
return
 "CommonResult{" +
                "code=" + code +
                ", msg='" + msg + '\'' +
                ", data=" + data +
                '}'
;
    }
}

  HttpHeaders headers = 
new
 HttpHeaders();
        headers.add(
"app_key","82328899
64
3506666"
);
        HttpEntity
<String> requestEntity = 
new
 HttpEntity<>(
null
, headers);
        String urlTemplate 
= "http://localhost/test?id=%s&type_id=%s"
;
        String url 
=
 String.format(urlTemplate,1,2);
        ResponseEntity
<CommonResult> responseEntity = restTemplate.exchange(url, HttpMethod.GET, requestEntity, CommonResult.
class
);
        
if
 (HttpStatus.OK ==
 responseEntity.getStatusCode()) {
            CommonResult commonResult 
=
 responseEntity.getBody();
            
if
 (ResultCode.SUCCESS ==
 commonResult.getCode()) {
                
return
 commonResult;
            } 
else
 {
                log.error(
"#method# 远程调用失败 code = [{}], msg = [{}]"
,
                        commonResult.getCode(), commonResult.getMsg());

            }
        } 
else
 {
            log.error(
"#method# 远程调用失败 httpCode = [{}]"
, responseEntity.getStatusCode());

        }
