How to create entity classes using database for all the existing tables?

Question

I am having tables created by a DBA and I intend to have entity classes for each table for further querying. Can any one suggest how to automatically create the entity classes using Eclipse?

Hibernate tools (part of JBoss Tools) can autogenerate entities from a database schema. Don't ask me how to use it though, I only managed to make it work through seam-gen which is part of the Seam 2 framework. — Gimby

If you use JPA for persistence, you can use "JPA tools" provided by Eclipse to generate java entity class from tables.

Here is the [tutorial][1]

Hi, would you please edit any answers linking to a personal website to include a disclosure of affiliation? As well, including some of the most important content from an external link is always a good idea to increase the value of answers.

I'll reword some of what miken32 said for clarity: the title of the article they linked to is "How to not be a spammer". When linking to your own content you must disclose that fact. This answer may be 7.5 years old, but your account appears to have been active as recently as this week. Please edit a disclosure in, and ideally also edit in the most important details from the blog post so the answer is no longer of low quality, or it may be flagged as spam and deleted.

You can generate classes using Hibernate Tools. There are two ways to generate these classes which is called as Reverse Engineering and Code Generation[dead link] -

You can use Hibernate Tools Eclipse Plugin.
You can write Ant Script using Hibernate tools jar.

You can try the Telosys code generator. It can help for this kind of job.

It allows to generate the Java (POJO) classes from any database with the basic templates and you can also create your own template (a Velocity file) to generate your DAO classes

For more information see https://www.telosys.org
