I am new to grails and intellij ide. I have run a grails project in intellij that's ok. But now I need to use mysql database instead of default. I have no idea how to do it. As much as I know i have changed my datasource class like below >>>
dataSource {
pooled = true
driverClassName = "com.mysql.jdbc.Driver"
dialect = "org.hibernate.dialect.MySQL5InnoDBDialect"
properties {
initialSize = 5
maxActive = 10
minIdle = 5
maxIdle = 5
maxWait = 100000
validationQuery = "select 1"
minEvictableIdleTimeMillis = 60000
timeBetweenEvictionRunsMillis = 60000
}
}
hibernate {
cache.use_second_level_cache = false
cache.use_query_cache = false
cache.provider_class = 'net.sf.ehcache.hibernate.EhCacheProvider'
}
// environment specific settings
environments {
development {
dataSource {
dbCreate = "update" // one of 'create', 'create-drop','update'
loggingSql = true
url = "jdbc:mysql://localhost/sbicloud_jan_13"
username = "root"
password = "admin"
}
}
test {
dataSource {
dbCreate = "update"
url = "jdbc:mysql://192.168.18.12/sbicloud"
username = "zia"
password = "zia123321"
}
}
production {
dataSource {
}
}
}
when I run the app some errors occur in console and the first is as below >>>
Cannot load JDBC driver class 'com.mysql.jdbc.Driver'
java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
Can anyone please help me on this?! It will be so helpful for me.
There are more or less 2 approaches:
Modify your BuildConfig.groovy so your application will use MySQL. In the BuildConfig there is a block called 'dependencies'
dependencies {
// specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes eg.
// runtime 'mysql:mysql-connector-java:5.1.20'
}
Uncomment the line:
// runtime 'mysql:mysql-connector-java:5.1.20'
And it will download the dependencies.
Put MySQL JDBC driver inside the grails-app/lib directory...
I posted a blog post sometime ago with instruction for this. Look here

What I'm pretending to do is to include the LDAP for internal users in a Guard Authentication System configured by ddbb.
I already have build my Guard Authentication System and works really nice thanks to https://knpuniversity.com/screencast/symfony-security.
But I need also to try to log in previously via LDAP mode. More precisely, the functionality must be like this:
The user try to log in on the Guard System Authentication configured with a database from MySQL and:
1- Check if exist the user in the table User from MySQL. If exist, we go to step 2. If not exist return false to the authentication with the error message.
2-Check if the user exist in the LDAP mode. If exist go to the step 3. If not exist go to the step 4.
3-Try to log in via LDAP with the username and password. If the authentication is ok, it's logged in. If can't match the password via LDAP, return false to the authentication with the error message.
4-After checking the LDAP option, we will just try to log in via Guard Authentication System. If the authentication it's ok, the user is logged in. If can't match the password via Guard with the MySQL users table, return false to the authentication with the error message.
In the LoginFormAuthenticator file I finally could manage this behavior I want as shows the next code.
<?php
namespace AppBundle\Security;
use ...
use Zend\Ldap\Ldap;
use Zend\Ldap\Exception\LdapException;
class LoginFormAuthenticator extends AbstractFormLoginAuthenticator
{
use TargetPathTrait;
private $em;
private $router;
private $passwordEncoder;
private $csrfTokenManager;
public function __construct(...
}
public function getCredentials(Request $request)
{
...
}
public function getUser($credentials, UserProviderInterface $userProvider)
{
$username = $credentials['username'];
$ldapPassword = $credentials['password'];
$ldaphost = 'ldap.example.com'; // your ldap servers
$baseDn = 'dc=example,dc=es';
$options = [
'host' => $ldaphost,
'username' => $username,
'password' => $ldapPassword,
'bindRequiresDn' => false,
'accountDomainName' => 'example.es',
'baseDn' => $baseDn,
];
$userInterface = $this->em->getRepository('AppBundle:User')
->findOneBy(['email' => $username]);
$ldap = new Ldap($options);
try {
$ldap->bind();
$userInterface->setIsAuthenticationLDAP(true);
} catch (LdapException $zle){
$userInterface->setIsAuthenticationLDAP(false);
}
return $userInterface;
}
public function checkCredentials($credentials, UserInterface $user)
{
$password = $credentials['password'];
if($user->isAuthenticationLDAP()){
$user->setLoginAttempts(0);
$this->em->persist($user);
$this->em->flush();
return true;
} else {
if($this->passwordEncoder->isPasswordValid($user, $password)) {
$user->setLoginAttempts(0);
$this->em->persist($user);
$this->em->flush();
return true;
} else {
if($user->getLoginAttempts() == '0') $user->setFirstLoginAttempt(new \DateTime('now'));
$user->setLoginAttempts($user->getLoginAttempts() + 1);
if($user->getLoginAttempts() >= 5) {
$user->setLockedDateTime(new \DateTime('now'));
$user->setLoginAttempts(0);
}
$this->em->persist($user);
$this->em->flush();
}
}
return false;
}
public function onAuthenticationSuccess(Request $request, TokenInterface $token, $providerKey)
{
....
}
protected function getLoginUrl()
{
return $this->router->generate('fos_user_security_login');
}
}
I hope anyone can enjoy this answer.

I am Grails newbie. After doing some basic configuration in Datasource.groovy, my grails app fails to start. I get the below error

your driverClassName is wrong. use the correct one for mysql (in the environments, e.g. com.mysql.jdbc.Driver), where you need mysql. right now you have:
default: driver=h2, dialect=mysql;
dev: url=mysql
prod: url=h2
you definetly want to clean this up. also make sure, you have the driver in your deps.
i'm trying to connect grails to mysql but i get this error:

Change runtime 'mysql:mysql-connector-java:5.1.23-bin'
to
runtime 'mysql:mysql-connector-java:5.1.34'
That should pull in the dependency correctly.
Ok I am having real difficulty solving this. I'm trying to connect to a mysql database from a zend application and i receive the following error:
Message: No database adapter present
I have checked and double checked the connection credentials and they should be fine. The code should be fine too as it works ok in the development environment. If I deliberately change the password to be incorrect in the development environment, I get exactly the same error, which leads me to believe that maybe this is the case, despite my checking!
Any thoughts would be very welcome. If there's nothing obviously wrong here then maybe I need to look at the server/db/php settings?
Thanks!

Define your database as a resource
resources.db.adapter = pdo_mysql
resources.db.params.host = localhost
resources.db.params.username = user
resources.db.params.password = password
resources.db.params.dbname = test
In your main files you then need to do nothing but initiate a query without having to worry about assigning the database fvrom your config - its done in the inside, the DB resource is always chosen as the default adapter for your database transactions
