A very quick question, how am I going to do this below:
> db.blog.posts.findOne()
{
"_id" : ObjectId("4b253b067525f35f94b60a31"),
"title" : "A Blog Post",
"content" : "...",
"author" : {
"name" : "joe",
"email" : "joe@example.com"
}
}
I saw the answer in Javascript is like:
> db.blog.posts.update({"author.name" : "joe"}, {"$set" : {"author.name" : "joe schmoe"}})
But how am I going to do that in Java?
If I have a very deep level value has to be changed, am I supposed to use this way? like: "person.abc.xyz.name.address" ?
Using dot notation to access nested documents will work perfectly well in the Java Driver. Take a look at this StackOverflow answer:
MongoDB nested documents searching
For the Java Driver, the basic idea is to replace the Javascript objects with instances of BasicDBObject.
Here's another good reference for updating:
