RestTemplate中的三種請求方式postForObject、postForEntity、exchange

	public static void main(String[] args) {
		RestTemplate template = new RestTemplate();
    	String url = "http://127.0.0.1:12813/member/c2/f02";
    	// 封裝引數,千萬不要替換為Map與HashMap,否則引數無法傳遞
    	MultiValueMap<String, Object> paramMap = new LinkedMultiValueMap<String, Object>();
    	paramMap.add("dt"

); postForObject(template, paramMap, url); postForEntity(template, paramMap, url); exchange(template, paramMap, url); } public static String postForObject(RestTemplate template,MultiValueMap<String, Object> paramMap,String url){ // 1、使用postForObject請求介面 String result =
