RestTemplate方法总结

一、postForObject方法(含请求头)

 MultiValueMap<String, Object> para = new LinkedMultiValueMap<>();//非请求头参数 路径参数(body参数)
 para.add("SFCODE", sfcode);
 para.add("PAGE_NO", pageNo);
 para.add("PAGE_SIZE", pageSize);
 HttpHeaders requestHeaders = new HttpHeaders();
 requestHeaders.set("ACTION","RP001");//自定义header参数
 HttpEntity<MultiValueMap> requestEntity =new HttpEntity<MultiValueMap>(para, requestHeaders);
 String result = restTemplate.postForObject("http://ip:port/test/method", requestEntity, String.class);
 System.out.print(result);
