Question

这适用于OrientDB以前的（beta）版本，不再适用。那么这样做的正确方法是什么？

用例：创建新（Document）数据库时，我想更改admin用户的密码。代码：

ODatabaseDocumentTx oDb = ...
if (!oDb.exists()) {
        // this will create AND open the database with credentials "admin"/"admin"
        oDb.create();
        // the "admin" user MUST exists, otherwise it is recreated / "repaired" during login, see OSecurityShared. 
        // So we always use 'admin' as name and only change the password
        if ("admin".equals(userName)) {
            OSecurityUser admin = oDb.getUser();
            admin.setPassword(password);
....

这将抛出java.lang.UnsupportedOperationException

java.lang.UnsupportedOperationException: null
at
com.orientechnologies.orient.core.metadata.security.OImmutableUser.setPassword(OImmutableUser.java:132)

Answer 1

引入了不可变用户来改进多线程。您始终可以获取基础文档。

尝试这应该工作

ODocument admin = db.getUser().getDocument();
admin.field("password","newpassword");
admin.save();

Answer 2

这似乎是另一种解决方案：

// change username and password
ODatabaseDocumentTx database = orientGraphFactory.getDatabase();
OCommandSQL cmd = new OCommandSQL("UPDATE ouser "
  + "SET name = '" + "newName" + "', "
  + "password = '" + "newPassword" + "'"
  + " WHERE name = 'admin'");
database.command(cmd).execute();
database.close();

它会触发编码密码的正确数据库挂钩。
