Bean Validation Support Becomes more Powerful in Maia

Konstantin Bulenkov

In earlier post about Bean Validation support, we focused on Java related things. In other words, we only talked about Bean Validation support in Java code. IntelliJ IDEA 9 (Maia) also has powerful Bean Validation support in XML descriptors (validation.xml and XMLs describing constraint mappings).

Let’s start from filling out validation.xml. All features like classes/packages completion are working as we’re expecting them to:

And, of course, all standard inspections like wrong class, package or file path also work here.

Let’s talk about constraint mappings files.

When default package is defined we can use relative class names and completion knows about that:

Local inspections detect missing parameters in constraints and allows paste necessary parameters with default values:

Just press Alt+Enter and select Add missing parameters. This quick-fix detects primitive types, Strings and Enums:

This change can also be viewed in Bean Validation tool window:

Completion for Enum types automatically detects possible values:

There is also a value checker for primitives, Enums and Class types:

RegExp Language injection for Pattern annotation is also supported:

Bean Validation tool window lets you easily view your definitions in constraint mappings files.

And don’t you worry about refactoring code. All changes are applied to validation.xml and all constrain mappings files:

To add Bean Validation support for your module in Maia, do the following :

  1. Open your project settings (Ctrl+Shift+Alt+S) and go to the Modules section
  2. Select a module and click + or press Alt+Insert and then select Bean Validation facet
  3. Select Hibernate Validator 4.0.0.Beta2 or other and press Fix button to let IntelliJ IDEA download and configure all required libraries

    Could you please provide a working example of Hibernate Validator using XML descriptors (validation.xml and XMLs describing constraint mappings). I am in need of that and i am not able to find any and what ever i got is not working. So please give me a working example like a zip file!!!???

    Thanks in advance

    Hello Nelson!
    what version of IntelliJ IDEA are you using? Have you set up bean validation facet? Do you have Bean Validation support enabled (Bean Validation support plugin should be enabled) ?
