restTemplate

1、get请求
第二个是返回值
SeoManager seo =restTemplate.getForObject(url + “getSeoManager?elementId={elementId}&appId={appId}”,SeoManager.class, id,getAtlasAppId());

2、普通post请求
第三个是返回值：
Long atlasId = restTemplate.postForObject(this.atlasRepository + “add”, atlas, Long.class);

3、请求参数为空
String str = template.postForObject(url+param,null, String.class);

4、没有返回值
1）、restTemplate.put(url+“deleteComplaintPageBigField?arg0={arg0}”,null, complaintPageContent.getId());

2）、HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_JSON_UTF8); // 在header里面设置编码方式
HttpEntity requestEntity = new HttpEntity(oldContent , headers);
restTemplate.put(this.complaintPageContentRepository + “updateComplaintPageContent”, requestEntity);

5、返回值为list集合
服务端用@RequestBody 接收

ParameterizedTypeReference<List<ComplanitXtree>> typeRef = new ParameterizedTypeReference<List<ComplanitXtree>>() {
		};
		ResponseEntity<List<ComplanitXtree>> responseEntity = restTemplate.exchange(this.complaintPageCategoryRepository + "getCateForXTree", HttpMethod.POST, null, typeRef);
		List<ComplanitXtree> topNodes = responseEntity.getBody();

6、可变长度参数

public Object delete(@RequestParam(value = "ids")Long... ids) {

		try {
			
            String rs = restTemplate.getForObject(this.complaintPageContentRepository + "deleteComplaintPageContent?ids={ids}", String.class,StringUtils.join(ids, ","));

            if("success".equals(rs)){
                return responebodyResult(HttpStatus.OK);
            }else{
                return responsebodyError();
            }

		} catch (Exception e) {
			e.printStackTrace();
			logger.error("delete",e);
            return responsebodyError();
        }
	}

@RequestMapping("/deleteComplaintPageContent")
	public String deleteComplaintPageContent(Long... ids) {

        try {
            complaintPageContentDao.deleteComplaintPageRelated(ids);
            complaintPageContentDao.deletes(ids);
            complaintPageBigFieldDao.deletes(ids);
            return "success";
        } catch (Exception e) {
            e.printStackTrace();
            return "false";
        }
    }
