1. Create a new Grails application by typing in the following command in terminal window:
grails create-app grailsDbConn
2. Change to the application directory by typing the following command in terminal window:
cd grailsDbConn
3. Create a new Domain Class by typing in the following command in terminal window:
grails create-domain-class db.Employee
4. Open Employee.groovy file in your favorite IDE and edit it to the following:
package db
class Employee {
String employeeID
String firstName
String lastName
String dateOfBirth
static constraints = {
}
}
5. Create a new Controller by typing in the following command in terminal window:
grails create-controller db.Employee
6. Open EmployeeController.groovy in your favorite IDE and edit it to the following:
package db
class EmployeeController {
def scaffold = Employee
}
7. Open DataSource.groovy file located at grails-app/conf in your favorite IDE to include the data source information
dataSource {
dbCreate = "create-drop"
driverClassName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"
url="jdbc:sqlserver://localhost:1433;DatabaseName=[YOUR_DB_NAME]"
username = "sa"
password = "[YOUR_PASSWORD]"
}
The updated DataSource.groovy file will look like the following:
dataSource {
pooled = true
driverClassName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"
url="jdbc:sqlserver://localhost:1433;DatabaseName=[YOUR_DATABASE]"
username = "sa"
password = "[YOUR_PASSWORD]"
dbCreate = "create-drop"
loggingSql = true
}
hibernate {
cache.use_second_level_cache = true
cache.use_query_cache = false
cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory' // Hibernate 3
// cache.region.factory_class = 'org.hibernate.cache.ehcache.EhCacheRegionFactory' // Hibernate 4
}
// environment specific settings
environments {
development {
dataSource {
dbCreate = "create-drop"
driverClassName = "com.microsoft.sqlserver.jdbc.SQLServerDriver"
url="jdbc:sqlserver://localhost:1433;DatabaseName=[YOUR_DATABASE]"
username = "sa"
password = "[YOUR_PASSWORD]"
}
}
test {
dataSource {
dbCreate = "update"
url = "jdbc:h2:mem:testDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
}
}
production {
dataSource {
dbCreate = "update"
url = "jdbc:h2:prodDb;MVCC=TRUE;LOCK_TIMEOUT=10000"
properties {
maxActive = -1
minEvictableIdleTimeMillis=1800000
timeBetweenEvictionRunsMillis=1800000
numTestsPerEvictionRun=3
testOnBorrow=true
testWhileIdle=true
testOnReturn=false
validationQuery="SELECT 1 from dual"
jdbcInterceptors="ConnectionState"
}
}
}
}
8. Download sqljdbc4.jar and place that in your application’s /lib directory.
9. Start Grails by typing in grails run-app in terminal window.
Please note that a Grails application will be run with the built in Tomcat server on port 8080 by default. If you may have Tomcat running on port 8080, you may want to specify a different port by using the server.port argument. In this case, run Grails by typing in grails -Dserver.port=8090 run-app in the terminal window.
10. Once the application is loaded successfully, you should have an Employee table in the database. Creating a new Employee using the app should create a new record in the table.
