Spring Boot 连接 mongpdb 报错

org.springframework.data.mongodb.UncategorizedMongoDbException: Exception authenticating MongoCredential{mechanism=SCRAM-SHA-256, userName='root', source='admin', password=<hidden>, mechanismProperties=<hidden>}; nested exception is com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=SCRAM-SHA-256, userName='root', source='admin', password=<hidden>, mechanismProperties=<hidden>}

确认用户名、密码以及鉴权数据库都是对的

使用MongoDB Compass 连接正常 。。

但是spring boot 连接失败

最终发现 yml中密码不能是纯数字，如果是纯数字，需要将密码改为字符串形式！

spring:
    data:
        mongodb:
            host: 192.168.68.200
            port: 27017
            username: root
            #password: 123456
            # 将纯数字密码加字符串
            password: '123456'
            database: testdb
            authentication-database: admin
