Question

I’ve a problem in my first grails application. I tried to modify my hibernate files a hundred times, but I still get this exception:

    | Error 2012-12-03 13:24:23,190 [localhost-startStop-1] ERROR context.GrailsContextLoader  - Error executing bootstraps:

User.groovy:

package test

class User {

    Integer id
    String f1
    String f2

    static constraints = {
    }
}

hibernate.cfg.xml

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
    '-//Hibernate/Hibernate Configuration DTD 3.0//EN'
    'http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd'>

<hibernate-configuration>

    <session-factory>
        <mapping resource='user.hbm.xml'/>
    </session-factory>

</hibernate-configuration>

EDIT: When I write –> everything works, so the error must be anywhere in user.hbm.xml…

user.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="test">
    <class name="test.User" table="test_user">
        <id name="id" column="id" type="java.lang.Integer" />
        <property column="f1" name="f1" type="java.lang.String" />
        <property column="f2" name="f2" type="java.lang.String" />
    </class>
</hibernate-mapping>

DataSource.groovy

dataSource {
    pooled = true
    driverClassName = "com.mysql.jdbc.Driver"
    username = "testuser"
    password = "testpass"
}
hibernate {
    cache.use_second_level_cache = true
    cache.use_query_cache = false
    cache.region.factory_class = 'net.sf.ehcache.hibernate.EhCacheRegionFactory'
}
// environment specific settings
environments {
    development {
        dataSource {
            dbCreate = "update" 
            url = "jdbc:mysql://localhost:3306/testdb?autoreconnect=true"
        }
    }
...

Any help is appreciated, thank you!

Answer 1

I removed all hibernate-mappings and used
static mapping = { table ‘groovy_user’ }
Thanks to Ian Roberts!
