mongodb授权失败：org.springframework.data.mongodb.UncategorizedMongoDbException

springboot 项目，在 properties 中配置 spring.data.mongodb.uri=mongodb://username:pwd@ip:27017/database

注意：如果 username 或者 pwd 中有特殊字符，需要 对 内容进行urlEncode

• 访问时报错啊如下：

org.springframework.data.mongodb.UncategorizedMongoDbException: Exception authenticating MongoCredential{mechanism=SCRAM-SHA-1, userName='xxx', source='xxxx', password=, mechanismProperties=}; nested exception is com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=SCRAM-SHA-1, userName='xxxx', source='xxxx', password=, mechanismProperties=}

1. 在资源路经中添加授权库名：authSource=admin
2. 加密方式：authMechanism=SCRAM-SHA-1

注意： url 的后边可以添加问号，后边可以添加很多拓展信息的。。。。

即： spring.data.mongodb.uri=mongodb://username:pwd@ip:27017/database?authSource=admin&authMechanism=SCRAM-SHA-1

如果是host，port 的方式：

spring.data.mongodb.authentication-database=admin
