MongoDB在银行海量历史订单交易数据查询中的应用(Spring boot + Bee)
近年来,随着各种便捷支付方式的普及,银行账户交易数据呈现爆炸式增长,同时数据模型也在不断变化,传统关系型数据库已难以满足这种海量的、模式灵活、高可用、高性能的数据存储和查询需求。通过对银行历史交易数据查询业务特点的分析,本文提出一种基于MongoDB数据库的银行海量历史订单交易数据查询解决方案,方案包括系统架构、数据模型、索引设计和分片键策略。实验表明,MongoDB能够实现海量的交易数据的存储和快速查询能力。

代码架构图:

MongoDB历史订单表的数据:

根据表,生成对应的Javabean:

new GenBean().genSomeBeanFile("orderhistory");

new GenBean().genAllBeanFile();  为所有表生成Javabean.  一行搞定

Javabean :

Spring boot  Application

@SpringBootApplication
public class Application {

	public static void main(String[] args) throws Exception {
		SpringApplication.run(Application.class, args);
	}

}

Spring boot Rest 代码:

@RestController
@RequestMapping("/orderhistory")
public class OrderhistoryRest {    

//	Mongodb使用
	@Resource(name = "mongodbObjSQLRichService")
	ObjSQLRichService objSQLRichService;


	@RequestMapping("/list")
	public Result list(Orderhistory orderhistory, 
			@RequestParam(value = "page", defaultValue = "1", required = false) int page,
			@RequestParam(value = "rows", defaultValue = "20", required = false) int rows) {
		Result result = new Result();
		try {
			objSQLRichService.setDataSourceName("ds0");
			int total = objSQLRichService.count(orderhistory);
			List<Orderhistory> list = objSQLRichService.select(orderhistory, (page - 1) * rows, rows);
			result.setRows(list);
			result.setTotal(total);
		} catch (BeeSQLException e) {
			Logger.error(e.getMessage(),e);
			result.setErrorMsg(e.getMessage());
		}catch (Exception e) {
			Logger.error(e.getMessage(),e);
			result.setErrorMsg(e.getMessage());
		}

		return result;
	}


}

为什么要有这句话,  因为ObjSQLRichService默认是使用JDBC的,访问传统的关系型数据库, 使用Mongodb时,需要指定.

@Resource(name = "mongodbObjSQLRichService")

bee.properties配置信息:

bee.db.dbName=MongoDB
bee.db.url = mongodb://localhost:27017/bee/
bee.db.username = 
bee.db.password = 


bee.osql.showSQL=true
bee.osql.showSql.showType=true
bee.osql.showSql.showExecutableSql=true

 将配置信息,放application.properties也是可以的.

MongoDB还可应用于外卖场景。使用MongoDB存储用户信息及用户发表的朋友圈信息，通过地理位置索引将快递骑手和快递商家的信息（包含位置信息）存储在MongoDB，然后通过地理位置查询，使得快递骑手能就近接单。

下次再介绍了.
