env： -Spring Boot 2.1.0（具有默认的spring依赖项）。
properties config： 数据： mongodb： uri：mongodb：// $ USER：$ PWD @ HOST：27017，HOST：27018 / $ DATABASE
我的pojo对象之一使用Index（unique = true），我使用mongo存储库进行CRUD操作。
因此，当启动弹簧启动时，我有了这个堆栈：
com.mongodb.MongoCommandException: Command failed with error 13 (Unauthorized): 'not authorized on DATABASE to execute command { createIndexes: "XXX
a", indexes: [ { key: { oid: 1 }, name: "oid", ns: "XXXX", unique: true } ] }' on server XXXX:27017. The full response is { "ok" : 0.0, "errmsg"
: "not authorized on XXX to execute command { createIndexes: \"XXXX\", indexes: [ { key: { oid: 1 }, name: \"oid\", ns: \"XXXXX\", unique:
true } ] }", "code" : 13, "codeName" : "Unauthorized" }
从mongo.log登录：

当我直接使用mongo shell时：
mongo mongodb://$USER:$PWD@HOST:27017,HOST:27018/$DATABASE
我可以正确执行createIndexes。

使用mongoshell，在执行createIndexes之前，我已“成功通过身份验证为主体”。
那为什么弹簧靴会是这种情况？
没有副本集，我没有错误。
