如何使用java将json对象与mongodb中具有相同值存储的文档进行比较

Question

我试图将json与MongoDb中具有相同值的文档进行比较。但无论两者是否相同，它都会返回false。

所以伙计们，让我帮忙

我已经提供了有关我的代码的详细信息以获得帮助。

**//comparison code**
                DBObject dbObject = (DBObject)JSON.parse(json4);

                boolean val=collection.equals(dbObject);

                System.out.println(val);
                System.out.println(dbObject);

**//document stored into 'dummyColl' collection**
> db.dummyColl.find().pretty();
{
        "_id" : "11",
        "xml" : "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?><tr

**//json to compare with document stored into 'dummyColl' collection**
{ "_id" : "11" , "xml" : "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?><transperfect><DEV id=\"11\"><lastname>yong11</lastname><nickname>mook kim11</nickname><salary>mkyong11</salary><permanentAddress>10000011</permanentAddress><currentAddress>Bhopal11</currentAddress><contactNo>pune11</contactNo><email>99999999911</email><alternateMail>test11@basex.com</alternateMail><FacebookName>testA11@basex.com</FacebookName><Color>Tom11</Color></DEV></transperfect>"}
