docker run --name mongodb0 -v /data/mongodb0:/data/db -p 27017:27017 -e MONGO_INITDB_ROOT_USERNAME=root --privileged=true -e MONGO_INITDB_ROOT_PASSWORD=root -d mongo --auth

3.11.0
new MongoClient("127.0.0.1");
报错信息如下 Authentication failed :

之前创建的时候,创建的是root:root账号密码,所以
List adds = new ArrayList<>();
//ServerAddress()两个参数分别为 服务器地址 和 端口
ServerAddress serverAddress = new ServerAddress("127.0.0.1", 27017);
adds.add(serverAddress);
List credentials = new ArrayList<>();
//MongoCredential.createScramSha1Credential()三个参数分别为 用户名 数据库名称 密码
MongoCredential mongoCredential = MongoCredential.createScramSha1Credential("root", "testdb", "root".toCharArray());
credentials.add(mongoCredential);
MongoClientOptions.Builder builder = new MongoClientOptions.Builder();
//build.
//通过连接认证获取MongoDB连接
MongoClientOptions options = MongoClientOptions.builder()
//设置连接超时时间为10s
.connectTimeout(1000*10)
//设置最长等待时间为10s
.maxWaitTime(1000*10)
.build();
MongoClient client = new MongoClient(adds, credentials,options);
看起来没毛病,但是,报错,提示,认证失败

网上度娘了一圈,发现要创建新用户,于是,dos下连接到mongo库
mongo 127.0.0.1/admin -uroot -proot
一波命令操作猛于虎,一看结果气的抖
use admin
db.auth("root","root")
db.dbs 查看数据库
testdb
use testdb 使用数据库
db.createUser(
{
user:"java",
pwd:"123456",
roles:[{role:"dbOwner",db:"testdb"}]
}
)
提示 Use of SCRAM-SHA-256 requires undigested passwords:
[thread1] Error: couldn't add user: Use of SCRAM-SHA-256 requires undigested passwords :
_getErrorWithCode@src/mongo/shell/utils.js:25:13
DB.prototype.createUser@src/mongo/shell/db.js:1267:15
继续度娘,发现需要修改mechanisms加密方式,增加 mechanisms : ["SCRAM-SHA-1"],执行成功
db.createUser(
{
user:"java",
pwd:"123456",
roles:[{role:"dbOwner",db:"testdb"}],
mechanisms : ["SCRAM-SHA-1"]
}
)
再修改用户名密码,连上
MongoCredential.createScramSha1Credential("java", "testdb", "123456".toCharArray());
这个连接从创建容器到java连接,尝试了很多次,作为一个程序员,一定要有耐心。慢慢研究下去终会成功。
