Question

在以下代码段中，我无法从redis读取（GET）值。

ApplicationContext applicationContext = new ClassPathXmlApplicationContext("SpringContext.xml");

   User user = new User(); // java Bean

 RegistrationBean bean = (RegistrationBean) applicationContext.getBean("RegistrationBean");

         User user = new User();
        user.setUserid("200112021");
        user.setName("name1");
        user.setAddress("adress sd");
bean.getRedisTemplate().opsForHash().put("A12", user.hashCode(),user);


User x = (User)bean.getRedisTemplate().opsForHash().get("A12",user.hashCode());
System.out.println(x.getName());

上面的代码只在同时使用PUT和GET时运行，但是如果不使用PUT并且只使用GET用于特定记录，那么我会得到NULL值pls建议吗？

问题已解决......

我使用了Spring MVC API。以下是代码段

public String addcustomer（@ModelAttribute（＆＃34; customer＆＃34;）customerVO customer，ModelMap model）{//从UI获取客户数据

    model.addAttribute("QuestionName", customer.getQuestionName());
    model.addAttribute("comments", customer.getComments());
    model.addAttribute("pollID", customer.getPollID());
    model.addAttribute("answer", customer.getAnswers());

    ApplicationContext applicationContext = new ClassPathXmlApplicationContext("servletDispatcher-servlet.xml");


  CustomerRepository customerRepository = (CustomerRepository) applicationContext.getBean("customerrepository");

    customerRepository.put(customer);
    System.out.println(" Step 1 output : " + customerRepository.getObjects());

如果仅使用GET，则无法读取redis值
