Spring Data MongoDB - Spring Web Services - Parent - SpringSource

please define productname in your docbook file!public interface MongoDbFactory {DB getDb() throws DataAccessException;}DB getDb(String dbName) throws DataAccessException;The following sections show how you can use the contiainer with either Java or the XML based metadatato configure an instance of the MongoDbFactory interface. In turn, you can use the MongoDbFactoryinstance to configure MongoTemplate.The class org.springframework.data.mongodb.core.SimpleMongoDbFactory providesimplements the MongoDbFactory interface and is created with astandard com.mongodb.Mongo instance, the database name and an optionalorg.springframework.data.authentication.UserCredentials constructor argument.Instead of using the IoC container to create an instance of MongoTemplate, you can just use them instandard Java code as shown below.public class MongoApp {private static final Log log = LogFactory.getLog(MongoApp.class);public static void main(String[] args) throws Exception {MongoOperations mongoOps = new MongoTemplate(new SimpleMongoDbFactory(new Mongo(),"database"));mongoOps.insert(new Person("Joe", 34));log.info(mongoOps.findOne(new Query(where("name").is("Joe")), Person.class));}}mongoOps.dropCollection("person");The code in bold highlights the use of SimpleMongoDbFactory and is the only difference between thelisting shown in the getting started section.Registering a MongoDbFactory instance using Java based metadataTo register a MongoDbFactory instance with the container, you write code much like what washighlighted in the previous code listing. A simple example is shown below@Configurationpublic class MongoConfiguration {}public @Bean MongoDbFactory mongoDbFactory() throws Exception {return new SimpleMongoDbFactory(new Mongo(), "database");}To define the username and password create an instance oforg.springframework.data.authentication.UserCredentials and pass it into theconstructor as shown below. This listing also shows using MongoDbFactory register an instance ofMongoTemplate with the container.1.4.0.BUILD-SNAPSHOTSpring Data MongoDB -Reference Documentation 31
