No @Filters required. You would set it up as follows:</p>
<ul>
<li>Implement the tenant views.</li>
<li>Configure Hibernate for DATABASE multitenancy.</li>
<li>Each tenant DataSource uses unique credentials (to trigger filtering at the view level).</li>
<li>Use an Interceptor to block cross tenant updates (database triggers are an option as well).</li>
</ul> <p style="margin: 10px 0 0">In addition to the baseline requirements, this approach has a few bonuses:</p>
<ul>
<li>It works with Hibernate CRUD operations</li>
<li>It works with Hibernate NativeQuery</li>
<li>It works with external frameworks that by bypass Hibernate (e.g. a 3rd party reporting tool).</li>
</ul> <p style="margin: 10px 0 0">It also allows you to run discriminator, schema and database multitenancy simultaneously with the same code base (mentioned in some previous comments).</p> <p style="margin: 10px 0 0">Here's some sample code: <a href="https://github.com/RJBTechnology/rjb-blog-multitenancy" class="external-link" rel="nofollow" style="color: #3b73af; text-decoration: none">https://github.com/RJBTechnology/rjb-blog-multitenancy</a></p> <p style="margin: 10px 0 0">For step by step details, see my blog post: <a href="https://rjbtechnology.com/blog/2017-01/discriminator-multitenancy-with-spring-and-hibernate-no-filters/" class="external-link" rel="nofollow" style="color: #3b73af; text-decoration: none">https://rjbtechnology.com/blog/2017-01/discriminator-multitenancy-with-spring-and-hibernate-no-filters/</a> </p> </td>
