 @Test
    public void testJson(){
        //bean 2 json
       User user = new User();
       user.setName("danny");
       user.setAge(11);
       user.setSex("male");
       logger.info(JSON.toJSONString(user));
       //json 2 bean
       String jsonStr = "{\"age\":88,\"name\":\"danny11\",\"sex\":\"male\"}";
       User danny = JSON.parseObject(jsonStr, User.class);
       logger.info("danny--->" + danny.getName());
       logger.info("danny--->" + danny.getAge());
       logger.info("danny--->" + danny.getSex());
