@Configuration
@EnableMongoRepositories(basePackages = { "com.frugalis.repository" })
@ComponentScan(basePackages = { "com.frugalis.*" })
@PropertySource("classpath:application.properties")
public class MongoJPAConfig extends AbstractMongoConfiguration {

    @Value("${com.frugalis.mongo.database}")
    private String database;
    @Value("${com.frugalis.mongo.server}")
    private String host;
    @Value("${com.frugalis.mongo.port}")
    private String port;
    @Value("${com.frugalis.mongo.username}")
    private String username;
    @Value("${com.frugalis.mongo.password}")
    private String password;


    @Override
    protected String getDatabaseName() {
        return database;
    }

    @Override
    protected String getMappingBasePackage() {
        return "com.frugalis.entity.mongo";
    }

    @Bean
    public MongoTemplate mongoTemplate() throws Exception {
        return new MongoTemplate(mongoClient(), getDatabaseName());
    }

    @Override
    @Bean
    public MongoClient mongoClient() {

        List allCred = new ArrayList();
        System.out.println("???????????????????"+username+" "+database+" "+password+" "+host+" "+port);
        allCred.add(MongoCredential.createCredential(username, database, password.toCharArray()));
        MongoClient client = new MongoClient((new ServerAddress(host, Integer.parseInt(port))), allCred);
        client.setWriteConcern(WriteConcern.ACKNOWLEDGED);

        return client;
    }}
