需求

通过调京东财务余额接口，在项目中开发相应管理页面。

实现

后端

因为京东的接口返回值里面已经有分页的参数了，因此会和平常自己写分页的逻辑有点区别。

京东财务余额Controller

/**
 * @Description:   京东财务余额Controller
 */
@RestController
@Slf4j
@AllArgsConstructor
@RequestMapping("/jdbalance")
@Api(value = "jdbalance", tags = "京东财务余额API")
public class JDBalanceController {

	@Autowired
	private JDBalanceService jinDongBalanceService;

	@GetMapping("/page")
	public R callbackBalanceDetail(Page page, JinDongBalanceVO jinDongBalanceVO) {
		return  R.ok(jinDongBalanceService.handleCallbackBalanceDetail(page,jinDongBalanceVO));
	}

}

京东财务余额Service

/**
 * @Description:  京东财务余额Service
 */
public interface JDBalanceService {

	/**
	 * @Description: 触发查询余额变动明细回调
	 */
	Page handleCallbackBalanceDetail(Page page, JinDongBalanceVO jinDongBalanceVO);

}

/**
 * @Description: 京东财务余额ServiceImpl
 */
@Service
@Slf4j
@AllArgsConstructor
public class JDBalanceServiceImpl implements JDBalanceService {

	@Autowired
	private JDConfigProperties jDConfigProperties;
	
	@Override
	public Page handleCallbackBalanceDetail(Page page, JinDongBalanceVO jinDongBalanceVO){

		Map<String, String> params = new HashMap<>();
		params.put("token", "");
		params.put("pageNum", Long.toString(page.getCurrent()));
		params.put("pageSize",Long.toString(page.getSize()));
		params.put("orderId", jinDongBalanceVO.getOrderId());
//		params.put("startDate", "");
//		params.put("endDate", "");
		String callbackBalanceDetailPath= jDConfigProperties.getQueryBalanceDetail();
		JSONObject jsResult =handle(callbackBalanceDetailPath, params);
		JSONArray resultArray = jsResult.getJSONArray(JDConstants.DATA);
		if(resultArray != null && resultArray.size() > 0){
			//将json转成需要的对象
			List<JinDongBalanceVO> jdBalanceList = com.alibaba.fastjson.JSONObject.parseArray(JSON.toJSONString(resultArray), JinDongBalanceVO.class);
			page.setRecords(jdBalanceList);
			page.setTotal(jsResult.getInt("total"));
		}
		return page;
	}

	private JSONObject handle(String path, Map<String, String> params) {
		String url = jDConfigProperties.getUrl() + path;
		log.info("请求url={}, params={}", url, params);
		// 执行请求
		String respStr = JDHttpUtils.httpPost(url, params);
		JSONObject js = new JSONObject(respStr);
		if (!JSONUtil.isJson(respStr)) {
			log.warn("查询余额明细返回的信息不是JSON格式,实际为[{}]", respStr);
			return js;
		}
		JSONObject jsResult = null;
		if (js.getStr(JDConstants.RESULTCODE).equals(JDResponseCode.SUCCESS)) {
			jsResult = js.getJSONObject(JDConstants.RESULT);
		}
		return jsResult;
	}

}
