相信看過上一篇文章的小伙伴已經(jīng)知道了， 這章要講的就是MongoDB主從配置。
在這邊文章中，你將要學(xué)到的是在項(xiàng)目中配置主從數(shù)據(jù)庫,并且兼容其他數(shù)據(jù)庫喲。。這些都是博主項(xiàng)目中需要并且比較重要的知識哦~
好了，廢話不多說，直接進(jìn)主題。

3.配置文件的編寫
在mongodb主從配置中，配置有所不同
1.配置父類AbstractMongoConfigure

到此，主從數(shù)據(jù)庫也講解完畢，如果有不懂或出bug的小伙伴可以留言我喲。。
以上這篇springboot配置多數(shù)據(jù)源的實(shí)例(MongoDB主從)就是小編分享給大家的全部內(nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持服務(wù)器之家。
