Mongodb Connection Error [java.lang.IllegalArgumentException: Prohibited character at position 0]
normalized = " "问题就找到了，password: 123456 没有按照属性的习惯设置修改 password 加上""OK , 可以正常访问mongodb啦， 从异常可以看到spring-boot-starter-data-mongodb-reactive 是构建在Netty Stream 之上的，Netty Stream 是基于Netty的，Netty作为网络编程框架是一个好的选

使用spring-boot-starter-data-mongodb-reactive 连接Mongodb 异常

OK , 可以正常访问mongodb啦， 从异常可以看到spring-boot-starter-data-mongodb-reactive 是构建在Netty Stream 之上的，Netty Stream 是基于Netty的，Netty作为网络编程框架是一个好的选择，也是一个好的开始。
