使用restTemplate报错：no suitable HttpMessageConverter found for response type [class java.lang.Object...

首先看一下报错

postman 请求是可以的
源码如下

/**
     *
     * @param unbindMultiMerchantDtoList
     */
    @Override
    public void unbind(List<UnbindMultiMerchantDto> unbindMultiMerchantDtoList) {
        String url = analysisPlatformUrl + "/Interface/Paas.aspx?Command=UnbindMultiMerchant";

    </span><span style="color: rgba(0, 0, 255, 1)">try</span><span style="color: rgba(0, 0, 0, 1)"> {

    } </span><span style="color: rgba(0, 0, 255, 1)">catch</span><span style="color: rgba(0, 0, 0, 1)"> (Exception ex) {

        log.error(</span>"&lt;== 商家解绑失败: {} "<span style="color: rgba(0, 0, 0, 1)">, JSON.toJSONString(unbindMultiMerchantDtoList), ex);
    }
}</span></pre>

将返回体的 Object 换 String 就可以了
