BeetSql是一個(gè)全功能DAO工具, 同時(shí)具有hibernate 優(yōu)點(diǎn) & Mybatis優(yōu)點(diǎn)功能,適用于承認(rèn)以SQL為中心,同時(shí)又需求工具能自動(dòng)能生成大量常用的SQL的應(yīng)用。
beatlsql 優(yōu)點(diǎn)
-
開(kāi)發(fā)效率
- 無(wú)需注解,自動(dòng)使用大量?jī)?nèi)置SQL,輕易完成增刪改查功能,節(jié)省50%的開(kāi)發(fā)工作量
- 數(shù)據(jù)模型支持Pojo,也支持Map/List這種快速模型,也支持混合模型
- SQL 模板基于Beetl實(shí)現(xiàn),更容易寫(xiě)和調(diào)試,以及擴(kuò)展
-
維護(hù)性
- SQL 以更簡(jiǎn)潔的方式,Markdown方式集中管理,同時(shí)方便程序開(kāi)發(fā)和數(shù)據(jù)庫(kù)SQL調(diào)試。
- 可以自動(dòng)將sql文件映射為dao接口類
- 靈活直觀的支持支持一對(duì)一,一對(duì)多,多對(duì)多關(guān)系映射而不引入復(fù)雜的OR Mapping概念和技術(shù)。
- 具備Interceptor功能,可以調(diào)試,性能診斷SQL,以及擴(kuò)展其他功能
-
其他
- 內(nèi)置支持主從數(shù)據(jù)庫(kù)支持的開(kāi)源工具
- 支持跨數(shù)據(jù)庫(kù)平臺(tái),開(kāi)發(fā)者所需工作減少到最小,目前跨數(shù)據(jù)庫(kù)支持mysql,postgres,oracle,sqlserver,h2,sqllite,DB2.

這幾個(gè)依賴都是必須的。
整合階段
由于springboot沒(méi)有對(duì) beatlsql的快速啟動(dòng)裝配,所以需要我自己導(dǎo)入相關(guān)的bean,包括數(shù)據(jù)源,包掃描,事物管理器等。

在resouces包下,加META_INF文件夾,文件夾中加入spring-devtools.properties:

restart.include.beetl=/beetl-2.3.2.jar restart.include.beetlsql=/beetlsql-2.3.1.jar |
在templates下加一個(gè)index.btl文件。
加入jar和配置beatlsql的這些bean,以及resources這些配置之后,springboot就能夠訪問(wèn)到數(shù)據(jù)庫(kù)類。
舉個(gè)restful的栗子

public interface AccountDao extends BaseMapper<Account> { @SqlStatement (params = "name" ) Account selectAccountByName(String name); } |
接口繼承BaseMapper,就能獲取單表查詢的一些性質(zhì),當(dāng)你需要自定義sql的時(shí)候,只需要在resouses/sql/account.md文件下書(shū)寫(xiě)文件:

selectAccountByName === *根據(jù) name 獲account select * from account where name = # name # |
其中“=== ”上面是唯一標(biāo)識(shí),對(duì)應(yīng)于接口的方法名,“* ”后面是注釋,在下面就是自定義的sql語(yǔ)句,具體的見(jiàn)官方文檔。
web層
這里省略了service層,實(shí)際開(kāi)發(fā)補(bǔ)上。

通過(guò)postman 測(cè)試,代碼已全部通過(guò)。
個(gè)人使用感受,使用bealsql做了一些項(xiàng)目的試驗(yàn),但是沒(méi)有真正用于真正的生產(chǎn)環(huán)境,用起來(lái)非常的爽。但是springboot沒(méi)有提供自動(dòng)裝配的直接支持,需要自己注解bean。另外使用這個(gè)orm的人不太多,有木有坑不知道,在我使用的過(guò)程中沒(méi)有遇到什么問(wèn)題。另外它的中文文檔比較友好。
