Spring数据中的findAll（）Mongodb无法正常工作

Question

当我尝试从数据库中检索数据时，我遇到了MongoOperations类的findAll（）方法的问题。其实我想得到参数的值：iliteID，纬度，经度，高度等。 任何人都可以帮忙解决这个问题吗？

提前致谢。

这里是数据库中的数据结构： （注意：数据以表格形式输入并从Servlet保存到数据库中）

> db.ILites.find().pretty()
{
    "_id" : ObjectId("56727fd1b955631adcee6fb1"),
    "iLiteID" : "I_Lite1",
    "Latitude" : 48.2188,
    "Target Power" : 32,
    "Status" : "df",
    "Ip Address" : "3.3.3.3",
    "Longitude" : 11.6248,
    "Current Power" : 32,
    "Transmission" : "OFF",
    "Connectivity" : "we",
    "Height" : "23",
    "Nominal Message" : "df",
    "Emergency Message" : "wrwew"
   }
   {
    "_id" : ObjectId("56728061b955631adcee6fb3"),
    "iLiteID" : "I_Lite1",
    "Latitude" : 48.2187,
    "Target Power" : 43,
    "Status" : "dg",
    "Ip Address" : "2.2.2.2",
    "Longitude" : 11.6247,
    "Current Power" : 43,
    "Transmission" : "ON",
    "Connectivity" : "dgdf",
    "Height" : "34",
    "Nominal Message" : "cb",
    "Emergency Message" : "gdf"
   }

这里是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;
}

SprinMongoConfig Class

    final MappingMongoConverter converter = new MappingMongoConverter(
            mongoDbFactory(), new MongoMappingContext());
    /**
     * To remove "_class" field in collection which is useless and added by
     * default
     */
    converter.setTypeMapper(new DefaultMongoTypeMapper(null));

    final MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory(),
            converter);

    return mongoTemplate;

}
}
