因项目需要，系统中需要添加根据企业名称或统一信用代码查询企业信息的功能，所以整合了企查查的查询接口

我将代码稍微改造了一下，仅供参考，如有错误，劳您指出：

@Value("${qichacha.key}")
private String key;
@Value("${qichacha.secret}")
private String secret;

//搜索关键字（公司名、注册号、社会统一信用代码或KeyNo）注：社会组织、香港企业仅支持通过企业名称和KeyNo查询
@Log("企业信息列表")
@ApiOperation(value = "企业信息列表")
@GetMapping(value = "list.do" , produces = "application/json;charset=UTF-8")
public  R pageList(@RequestParam(value = "keyword")String keyword ,HttpServletRequest request) {
		List<EnterpriseInfoDO> resultList = new ArrayList<>();
		String reqInterNme = "http://api.qichacha.com/ECIV4/Search";
		String paramStr = "keyword="+keyword;
		try {
			// auth header setting
			HttpHead reqHeader = new HttpHead();
			String[] autherHeader = QiChaChaUtil.RandomAuthentHeader(key,secret);
			reqHeader.setHeader("Token", autherHeader[0]);
			reqHeader.setHeader("Timespan", autherHeader[1]);
			final String reqUri = reqInterNme.concat("?key=").concat(key).concat("&").concat(paramStr).concat("&pageSize=20");
			String tokenJson = HttpHelper.httpGet(reqUri, reqHeader.getAllHeaders());
			JSONObject jsonObject = JSON.parseObject(tokenJson);
			return R.ok().put("result",resultList);
		} catch (Exception e1) {
			e1.printStackTrace();
			return R.error("查询企业信息失败");
		}

建议把查询出的数据持久化到数据库，如有相同查询 直接从数据库返回数据。
