I think that it's a problem of DB Conex but I don't know to fix it. I use MySQL in my app and the service plan ClearDB MySQL Database Spark DB.
My Datasource.groovy is:
import org.springframework.cloud.CloudFactory
def cloud
try {
cloud = new CloudFactory().cloud
} catch(e) {}
dataSource {
pooled = true
driverClassName = "com.mysql.jdbc.Driver"
dialect = "org.hibernate.dialect.MySQL5InnoDBDialect"
username = "root"
password = "root"
}
hibernate {
cache.use_second_level_cache = true
cache.use_query_cache = true
cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory'
//cache.region.factory_class = 'org.hibernate.cache.EhCacheProvider'
}
environments {
development {
dataSource {
dbCreate = "create-drop"
url = "jdbc:mysql://localhost:8080/bbddSRL"
username="root"
password="root"
}
}
test {
dataSource {
dbCreate = "create-drop"
url = "jdbc:mysql://localhost:8080/bbddSRL"
username="root"
password="root"
}
}
production {
dataSource {
pooled = true
dbCreate = 'update'
driverClassName = 'com.mysql.jdbc.Driver'
if (cloud) {
def dbInfo = cloud.getServiceInfo('mysql-instance') //mysql-instance is the name of the ClearDB's service.
url = dbInfo.jdbcUrl
username = dbInfo.userName
password = dbInfo.password
} else {
url = 'jdbc:mysql://localhost:8080/bbddSRLprod'
username = 'root'
password = 'root'
}
}
}
}
Any anwers or suggestions?

Try eliminating the datasource block where you define dialect. You will have to still define the items in that block but do it in the datasource of each environment. I did this because it seemed like any changes that I made to the datasource within the environment had no effect.
