啟動(dòng)spring boot 結(jié)果直接報(bào)mongodb錯(cuò)誤，挺奇怪的工程還沒有配置mongodb 。

猜想是不是工程有mongodb jar包

然后 boot 自然配置了

查了資料原來

springboot自動(dòng)配置了支持mongodb。在啟動(dòng)springboot時(shí)會(huì)自動(dòng)實(shí)例化一個(gè)mongo實(shí)例。

現(xiàn)在要禁用自動(dòng)配置

@SpringBootApplication(exclude = MongoAutoConfiguration.class)：

這個(gè)注解可以禁用springboot自帶的配置。

在SpringBoot使用MongoDB時(shí)出現(xiàn)的bug和解決

在springboot整合MongoDB時(shí),報(bào)錯(cuò)

INFO 67135 — [ main] org.mongodb.driver.connection : Closed connection [connectionId{localValue:2}] to 127.0.0.1:27017 because there was a socket exception raised by this connection.
org.springframework.data.mongodb.UncategorizedMongoDbException: Exception authenticating MongoCredential{mechanism=SCRAM-SHA-1, userName=‘root’, source=‘demo’, password=, mechanismProperties=}; nested exception is com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=SCRAM-SHA-1, userName=‘root’, source=‘demo’, password=, mechanismProperties=}

報(bào)錯(cuò)的話說是權(quán)限什么的,可以把properties文件中mongodb.uri改一下:

spring.data.mongodb.uri=mongodb://root:123456@127.0.0.1:27017/demo?authSource=admin&authMechanism=SCRAM-SHA-1

root是賬號(hào),123456是密碼,demo是數(shù)據(jù)庫(kù)名字,改為自己的

總結(jié)

以上為個(gè)人經(jīng)驗(yàn)，希望能給大家一個(gè)參考，也希望大家多多支持腳本之家。
