JAVA调用WebService并展示数据于前端

    @RequestMapping(value = "/getStockWebInfo")
    @ResponseBody
    public Object getStockWebInfo(String webserviceUrl){
        WsReturnData ws = new WsReturnData();
        List<Map<String, Object>> listMap = new ArrayList<>();
        try {
            if (!StringUtils.isEmpty(webserviceUrl)) {               
                // 创建WebService客户端代理工厂
                JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
                // 判断是否抛出异常
                factory.getOutInterceptors().add(new LoggingInInterceptor());
                // 注册webservice接口
                factory.setServiceClass(StockWebService.class);
                // 配置webservice地址
                factory.setAddress(webserviceUrl);
                // 获得接口对象
                stockWebService = (StockWebService) factory.create();
                // 调用接口方法
                ws = stockWebService.getStockInfo();
                for (int i = 0; i < ws.getListData().size(); i++) {
                    Map<String, Object> queryMap = new HashMap<>();
                    queryMap.put("LOCCD", ws.getListData().get(i).getLOCCD());
                    queryMap.put("QTY1", ws.getListData().get(i).getQTY1());
                    listMap.add(queryMap);
                }
                System.out.println("调用结果:" + listMap);
                System.out.println("返回结果:" + ws.getResultMsg());
                // 关闭接口连接（如果用于前端测试联通性并展示数据不能关闭接口连接）
                //System.exit(0);
            }    
        } catch (Exception e) {
            e.printStackTrace();
        }
        return listMap;
            
    }
