Java Spring数据Mongodb中的findAll（）不工作

当我试图从数据库检索数据时，MongoOperations类的findAll（）方法有问题。实际上我想得到参数的值：iliteID、纬度、经度、高度等等。。 有人能帮忙解决这个问题吗

提前谢谢

以下是数据库中的数据结构： （注意：数据以表单形式输入，并从Servlet保存到数据库中）

下面是java代码：

protected List<ILites> getAllILites(){
    ApplicationContext ctx = new AnnotationConfigApplicationContext(SpringMongoConfig.class);
    MongoOperations mongoOperation = (MongoOperations) ctx.getBean("mongoTemplate");

    List<ILites> ilites = mongoOperation.findAll(ILites.class, "ILites");

    System.out.println("#3 for advance");
    for (ILites temp : ilites) {

        // I am getting an "null" value instead of the value of the longitude
        System.out.println(temp.getLongitude());

        //This displays something like this : mongodb.model.ILites@732cbcd5 (which i don't really understand)
        System.out.println(temp);
    }

    return ilites;
}

Spring控制器类

/**
 *
 * @output ModelAndView
 * @description redirect to dashboard
 */

@RequestMapping(value = "/adminDashboard", method = RequestMethod.GET)
public ModelAndView adminPage() {
    userDao.updateLastLogin(getCurrentUser());
    final ModelAndView model = new ModelAndView();
    model.addObject("iLiteList", getAllILites());
    model.setViewName("adminDashboard");
    return model;
}

你没有真正解释你的问题。但我猜，您希望值height、status和Ipaddress存储在ILites对象中。尝试用@JsonProperty注释模型字段。很抱歉，我需要高度、状态等值。。要存储在ILites对象中。你是说像这样的@JsonProperty私有字符串状态；看这里。当我在spring项目中使用jackson注释时，我发现它们非常有用。这只是一个建议。对于给出的信息，我仍然帮不上什么忙。很抱歉，我对SpringJava非常熟悉。当我按照您的建议注释字段时，例如@JsonProperty（“Status”），它被标记为错误，spring建议的快速修复方法如下：@create annotation“JsonProperty”或Fix project setup。我该选哪一个？或者有其他方法可以修复此错误？好的，您缺少必要的库。总之，你需要学习基础知识。我建议在继续之前阅读有关java、maven、spring数据和spring mongo集成的简单教程。需要时间，但帮助很大。
