启动spring boot 结果直接报mongodb错误，挺奇怪的工程还没有配置mongodb 。

猜想是不是工程有mongodb jar包

然后 boot 自然配置了

查了资料原来

springboot自动配置了支持mongodb。在启动springboot时会自动实例化一个mongo实例。

现在要禁用自动配置

@SpringBootApplication(exclude = MongoAutoConfiguration.class)：

这个注解可以禁用springboot自带的配置。

在SpringBoot使用MongoDB时出现的bug和解决

在springboot整合MongoDB时,报错

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=}

报错的话说是权限什么的,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是账号,123456是密码,demo是数据库名字,改为自己的

总结

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
