初学Jackson树遍历

 

    @Autowired
    ObjectMapper mapper;
    @GetMapping(value = "/rest_json")
    public @ResponseBody String restJson() throws IOException {
        String json = "{\"name\":\"lijz\",\"id\":10}";
        JsonNode node = mapper.readTree(json);
        String name = node.get("name").asText();
        Integer id = node.get("id").asInt();
        return name+" "+id;
    }
