本文介绍了一种在Spring框架中配置MongoDB的方式，通过自定义MongoConfigurer类来实现MongoDB的连接配置，并展示了如何解决高版本MongoDatabaseFactory注入的问题。

@Configuration
public class MongoConfigurer {
    @Autowired
    MongoDatabaseFactory mongoDbFactory;
    @Autowired
    MongoMappingContext mongoMappingContext;

    @Bean
    public MappingMongoConverter mappingMongoConverter() {

        DbRefResolver dbRefResolver = new DefaultDbRefResolver(mongoDbFactory);
        MappingMongoConverter converter = new MappingMongoConverter(dbRefResolver, mongoMappingContext);
        converter.setTypeMapper(new DefaultMongoTypeMapper(null));

        return converter;
    }

}

高版本的MongoDatabaseFactory过期了没法注入，可以这么写：

@Configuration
public class MongoConfigurer {

    @Bean(name = "mongoTemplate")
    public MongoTemplate mongoTemplate(MongoDatabaseFactory mongoDatabaseFactory, MongoMappingContext mongoMappingContext) {
        DbRefResolver dbRefResolver = new DefaultDbRefResolver(mongoDatabaseFactory);
        MappingMongoConverter mappingConverter = new MappingMongoConverter(dbRefResolver, mongoMappingContext);
        //去掉_class字段
        mappingConverter.setTypeMapper(new DefaultMongoTypeMapper(null));
        return new MongoTemplate(mongoDatabaseFactory,mappingConverter);
    }
}
