how to connect mysql database in grails with intellij IDE - mysql

Question

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
