一、安裝mongodb4.0.3（××）
1.1、官方安裝文檔
https://docs.mongodb.com/manual/tutorial/install-mongodb-on-red-hat/
1.2、tar.gz包下載地址
https://www.mongodb.com/download-center/community?jmp=docs
1.3、復(fù)制集官方配置
https://docs.mongodb.com/manual/administration/replica-set-member-configuration/
二、springproject版本依賴（×）
spring：5.1.1.release 以上
springdatamongodb:2.1.1.release 以上
三、配置mongotransactionmanager（springboot使用方式）
springboot 集成非常簡(jiǎn)單，配置mongotransastionmanager，目前spring-boot-starter-data-mongodb 版本較低不支持，因此暫未驗(yàn)證，springboot配置復(fù)制集參考springboot相關(guān)文檔

四、配置mongotransactionmanager（普通spring項(xiàng)目）

七、最后是重點(diǎn)（×××××）
7.1、必須使用復(fù)制集，單節(jié)點(diǎn)不支持，mongodb4.2 會(huì)支持分片集事務(wù)，復(fù)制集安裝請(qǐng)自行研究
7.2、使用事務(wù)之前（@transaction），數(shù)據(jù)庫(kù)和文檔必須提前創(chuàng)建，如何解決呢？且看下篇
7.3、spring版本和springdatamongodb版本必須遵循 @springproject版本依賴
7.4、注意，此處的復(fù)制集不是4.0版本之前的主從復(fù)制集群，4.0之后已廢棄主從模式
以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持服務(wù)器之家。
