POHibernate's generator class not really working?
text
Body
copied!<p>Asking this question here after hours of frustration with me and my Eclipse. Hoping to find some respite here. </p> <p>I'm trying to save a pojo object into MySQL database via Hibernate 3.0. Basically my requirement is: I need to assign the id for the object before save and not let Hibernate do it for me.</p> <p>For this I looked up in the documentation and saw that <code><generator class="assigned"/></code> perfectly fits my bill. Consequently I updated by <code>.hbm.xml</code> file with the following for the <code>id</code>:</p> <pre><code><id name="id" type="int"> <column name="ID" /> <generator class="assigned" /> </id> </code></pre> <p>My pojo matches <code>.hbm.xml</code> file to the T.</p> <p>I'm setting all the parameters including the <code>ID</code> of my pojo and calling Hibernate's <code>saveOrUpdate(object)</code> method.</p> <p>If it's of any help, the <code>ID</code> column of my database table has "auto-inc" disabled.</p> <p>Unbelievably, when I look at the database table contents, a row has been inserted with Hibernate's own ID and not what I had set. </p> <p>How's it possible? Is there anything else affecting the <code>ID</code>? Am I missing on something? What's the work around?</p> <p>My <code>hibernate.properties</code> looks like below(if it's of any help):</p> <pre><code>hibernate.connection.driver_class =com.mysql.jdbc.Driver hibernate.dialect =org.hibernate.dialect.MySQLDialect hibernate.connection.url =jdbc:mysql://localhost/dbdbdbdbdb hibernate.connection.username=root hibernate.connection.password=password hibernate.connection.pool_size=10 jdbc.batch_size=30 hibernate.show_sql=true hibernate.current_session_context_class=true hibernate.hbm2ddl.auto=validate hibernate.cglib.use_reflection_optimizer=false hibernate.generate_statistics=true hibernate.cache.use_query_cache=true hibernate.cache.region.factory_class=net.sf.ehcache.hibernate.EhCacheRegionFactory </code></pre>
