@Override
public List getAll() {
return mongoTemplate.findAll(Type.class);
}
@Override
public Type findById(String id) {
Query query = query(where("typeId").is(id));
return mongoTemplate.findOne(query, Type.class);
}
@Override
public Type save(Type type) {
mongoTemplate.insert(type);
return type;
}
}
Listings 15-3 and Listing 15-4 show your implementation of the DocumentDAO and TypeDAO interfaces. As you
can see, you are using the MongoOperations class. This class is a template that provides functionality to operate with
MongoDB. The Spring Data-Mongo provides a set of templates and annotations that help to talk with a MongoDB
server, making it easy to interact with it.
Here you don’t need to map any class or go row by row. The document will be saved, as is, in a Mongo format,
something similar to JSON. Next, let’s see the XML configuration, shown in Listing 15-5, and how to interact with the
MongoDB server.
