    producer进行如下修改consumer不变

        @PostMapping("/odc.order.cache.update")
        public Integer orderCacheUpdate(@RequestBody Map<String,String> map){
    
            for (String key : map.keySet()) {
                List<Node> nodeList = JSON.parseArray(map.get(key), Node.class);
                System.out.println(nodeList.toString());
            }
    
            return map.size();
    
        }
    

    代码标记如下

    问题:不知道为什么按消费者要求的数据类型返回就会报错,不按消费者数据类型返回正常
