MongoDB set access permissions, set user, user name password access in Java

The following actions are based on the Windows platform

1. Start MongoDB Service

Mongod.exe--dbpath d:\mongodb-win32-x86_64-2.2.2\data--logpath d:\mongodb-win32-x86_64-2.2.2\log\mongo.log--auth

"--auth": Represents the need to access according to permissions, you must start the service with this parameter, the client can be a user name password to establish a connection

2. Start MONGO console MONGO

1. D:\mongodb-win32-x86_64-2.2.2\bin>mongo
2. MongoDB Shell version:2.2.2
3. Connecting To:test
4. >

3. Switch to the database you want to set up, create a user

1. > Use Caotian
2. Switched to DB Caotian
3. > Db.adduser ("Ctadmin", "111111");
4. {
5. "User": "Ctadmin",
6. "ReadOnly": false,
7. "pwd": "790457ca1e19341d5043766e9192c5b9",
8. "_id": ObjectId ("549943e6cbd0bdf00f57783b")
9. }
10. >

4. Establishing a connection in Java

1. try {
2. ServerAddress sa = new ServerAddress ("localhost", "27017");
3. Mongooptions options = new Mongooptions ();
4. Options.connectionsperhost = 200;//pool size (the drive's link pool size). /* Mongod--dbpath. \db--maxconns 20 (concurrent number) */default is 10
5. This.mongo = new MONGO (SA, options);
6. This.db = This.mongo.getDB ("Caotian");
7. char[] Pwd_char = "111111". ToCharArray ();
8. Boolean auth = db.authenticate ("Ctadmin", Pwd_char);
9. if (!auth) {
10. Logger.info ("======mongodb Initialization of permission validation error ======");
11. throw new RuntimeException ();
12. }
13. Logger.info ("======mongodb initialization completed ======");
14. } catch (Unknownhostexception e) {
15. E.printstacktrace ();
16. } catch (Mongoexception e) {
17. E.printstacktrace ();
18. }
