ショック!!restTemplateのgetとpostリクエストはなんと...

前言:

get方式の実現:

public static void main(String[] args) {
        RestTemplate restTemplate = new RestTemplate();
        String category = "0";
        String response = restTemplate.getForObject("http://*.*.*.*:8055/showAllBusiness/" + category,String.class);
        System.out.println(response);
    }

getForObject   url ， 

 token exchange 

post方式の実現：

 public static void main(String[] args) {
        RestTemplate restTemplate = new RestTemplate();
        String url = "http://*.*.*.*:3434/insuranceFeeRun"; //  
        //    token（ token ）
        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.APPLICATION_JSON);
        headers.set("token", "a2bbb914-5f46-4580-971d-dfdbcce50cdd");
        //post 
        Map<String, Object> params = new HashMap<>();
        params.put("filters",new ArrayList<String>());
        params.put("pageIndex",1);
        params.put("pageSize",10);
        params.put("sorts",new ArrayList<String>());

        String json = JSON.toJSONString(params);

        HttpEntity<String> request = new HttpEntity<>(json, headers);

        ResponseEntity<String> response = restTemplate.postForEntity( url, request , String.class );

        System.out.println(response.getBody());

    }

   post     token， header 

Exchange方式で実現(get、post、delete、put)
