Issue persisting long strings with Hibernate

Question

In my web application, I have a text area whose user-filled contents are ultimately persisted to the db with Hibernate. I have been running into an issue that when the user input is beyond a certain length, the persistence fails. Is there a way to indicate through Hibernate Annotations or in the configuration that this particular field should support longer strings, and that the database column type should reflect this?

Here's the exception that I'm getting:

Caused by: java.sql.BatchUpdateException: Data truncation: Data too long for column 'introText' at row 1

Answer 1

You could use the length parameter on the annotation, like so:

@Column(length=1000)

or you could change the column type to something like text if your database supports it, like so:

@Column(columnDefinition="text")

If you are using hbm2ddl update, and the column will be created to use that type instead (database specific).
