restTemplate发送get请求携带header

 

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","82328899643506666");
        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());
        }
