Question

我是Realm的新手。我在领域服务器上对不同用户的身份验证有困难。我写了几行代码来测试后续登录到服务器和域分离。

我以第一个用户pluto@qui.li
我填充RealmObject（UserApp）并将其保存到服务器
我用pluto@qui.li
我使用第二位用户paperino@qui.li
我检查没有为此用户填充UserApp（域名分隔）
我用paperino@qui.li
然后我再次尝试使用第一个用户pluto@qui.li登录，但是收到以下错误消息：

*java.lang.IllegalArgumentException: Configurations cannot be different if used to open the same file.

有人可以告诉我为什么吗？我对此代码的意图是使用realm测试android应用程序的胚胎登录/注销。用户应使用不同的凭据登录和退出应用程序。对我来说听起来应该有一种方法来为该用户获取以前创建的SyncConfiguration而不是创建一个新的...但是，如果是这种情况，我不知道该怎么做......。

这是我的代码：

// -----------主要代码：

  SyncUser userLogged;

    //Login with first user. This time the login completes successfully
    userLogged = loginUser("pluto@qui.li", "pluto");

    insertUserAppSyncRealm();

    RealmResults<UserApp> res = realm.where(UserApp.class)
            .beginsWith("username", "situs")
            .findAll();
    System.out.println(" @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Size table pippo " + res.size());
    UserApp resUser = res.last();
    System.out.println(" @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ ID " + resUser.getId());

    userLogged.logout();

    //Login with second user OK
    userLogged = loginUser("paperino@qui.li", "paperino");

    RealmResults<UserApp> res2 = realm.where(UserApp.class)
            .beginsWith("username", "situs")
            .findAll();  //arrivato qui da "Configurations cannot be different if used to open the same file"
    System.out.println(" @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Size table usertest " + res2.size());

    userLogged.logout();

    //Login again with first user. This time the login fails ("Configurations cannot be different if used to open the same file")
    userLogged = loginUser("pluto@qui.li", "pluto");

    RealmResults<UserApp> res3 = realm.where(UserApp.class)
            .beginsWith("username", "situs")
            .findAll();
    System.out.println(" @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ Size table pippo " + res3.size());

    userLogged.logout();

// -----------使用过的函数：

public SyncUser loginUser(String username, String password) {
    SyncUser userLogged;
    SyncCredentials myCredentials = SyncCredentials.usernamePassword(username, password, false);
    userLogged = SyncUser.login(myCredentials, authURL);
    setConfigurationSyncUser(userLogged);
    return userLogged;
}

public void setConfigurationSyncUser(SyncUser user) {
    String user1RealmUrl = "realm://localhost:9080/~/default";
    SyncConfiguration config = new SyncConfiguration.Builder(user, user1RealmUrl).
            errorHandler(new SyncSession.ErrorHandler() {
                public void onError(SyncSession session, ObjectServerError error) {
                    fail("Realm unexpected error: " + error);
                }
            })
            .build();

        realm = Realm.getInstance(config);  //fails ("Configurations cannot be different if used to open the same file")
}

public void insertUserAppSyncRealm() {
    UserApp user = new UserApp();
    populateUser(user);
    realm.beginTransaction();
    realm.insert(user);
    realm.commitTransaction();
}

private void populateUser(UserApp user) {
    user.setUsername("situs@qui.it");
    user.setPassword("12345678");
    user.setId(UUID.randomUUID().toString());
}

提前感谢你的善意......
