resttemplate 发送带header的post请求

Content-Type：application/json（常用方式，body为json字符串）

    @Autowired
    RestTemplate restTemplate;

    @Test
    public void testPost(){
        //设置请求头参数
        HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.add("appId","app_service");

        //设置body参数，并转成json字符串
        BasicDownloadForm basicDownloadForm = new BasicDownloadForm();
        basicDownloadForm.setOrgCode("900000");
        basicDownloadForm.setDataType("INTERCEPT");
        basicDownloadForm.setPdaCode("JSYG22200110001");
        basicDownloadForm.setVersionNo("1573285609000");

        String content = JSON.toJSONString(basicDownloadForm);

        HttpEntity<String> httpEntity = new HttpEntity<>(content, httpHeaders);

        String response = restTemplate.postForObject("http://xxxxxx.xxx.xx/xxxxxxx/xxxxx/xxxxxxxxxxxx", httpEntity, String.class);
        System.out.println(response);
    }

Content-Type：multipart/form-data

        //设置请求头参数
        HttpHeaders httpHeaders = new HttpHeaders();
        httpHeaders.add("appId","app_service");
        //设置content-type为multipart/form-data
        httpHeaders.setContentType(MediaType.MULTIPART_FORM_DATA);

        //设置body参数
        MultiValueMap<String, String> multiValueMap = new LinkedMultiValueMap<>();
        multiValueMap.add("orgCode","900000");
        multiValueMap.add("dataType","INTERCEPT");
        multiValueMap.add("pdaCode","JSYG22200110001");
        multiValueMap.add("versionNo","1573285609000");

        HttpEntity<MultiValueMap<String, String>> httpEntity = new HttpEntity<>(multiValueMap, httpHeaders);

        String response = restTemplate.postForObject("http://xxxxxx.xxx.xx/xxxxxxx/xxxxx/xxxxxxxxxxxx", httpEntity, String.class);
        System.out.println(response);
