[hibernate-issues] [Hibernate-JIRA] Created: (HHH-7286) SessionFactory getImplementors method causes performance issues with entity-name attribute
SessionFactory getImplementors method causes performance issues with entity-name
attribute
------------------------------------------------------------------------------------------
Key: HHH-7286
URL: https://hibernate.onjira.com/browse/HHH-7286
Project: Hibernate ORM
Issue Type: Improvement
Components: core
Affects Versions: 3.6.5
Environment: Hibernate 3.6.5 Final, Orcale database 11g, JBoss 4.2.2
Reporter: Alain Menu
Hibernate provokes useless accesses to the class loader of JBoss due to the attribute
entity-name which is present in each hbm mapping file. Hibernate tries to instantiate a
class having this name before trying with the real name of the actual business object
which cause a performance overhead and contention under heavy load conditions
(benchmarking).
<hibernate-mapping package="com.example.hibernate.businessobject">
<class name="Employee" table="EMP"
entity-name="Employee_EMP">
<!-- cache usage="read-only"/ -->
<id name="trigramme" type="string" column="CODUSR"
/>
<property name="firstname" column="PREUSR"
type="string" />
<property name="name" column="NOMUSR" type="string"
/>
<property name="email" column="EMLUSR" type="string"
/>
</class>
</hibernate-mapping>
