Integration of SpringMVC with Hibernate Validator [SPR-4528]

[spring-projects-issues]

Ted Bergeron opened SPR-4528 and commented

Based on my article: http://www.triview.com/articles/hibernate/validator/canmeetyourneeds.html provide built in integration with hibernate validator.

This may be broken down into several issues:

1. Extend JSP tag library to search for validation annotations via reflection. Render fields with css classes such as required, email, etc. Add maxlength attribute, etc.
2. Native support to invoke the proper Hibernate ClassValidator and convert the InvalidValue array to a Spring Errors object.
3. Extend JSP tags to render semantic html wrapper around form fields. Include div, label and field.
4. Extend JSP tags to render with enhanced features, such as adding popup calendar for Date. Consider extracting info from assigned PropertyEditor.
5. Add basic, included JavaScript validation support and/or integration with a major javascript framework such as prototype, jquery, ext, etc.

Latest source code. Contains current tagfile implementations and most tagfiles reimplemented as taglibs that extend the Spring form taglibs. Contains ant build.xml that will build a jar suitable for use in projects.

Two unrelated enhancements are available in the first attachment:

1. A DateEditor that accepts seperate parsing and rendering DateFormats.

For example, in the USA users constantly want to enter dates short hand, or with a 4 digit year. I use:
public static final String RENDERING_DATE_FORMAT = "MM/dd/yyyy";
public static final String PARSING_DATE_FORMAT = "MM/dd/yy";

2. Support for arbitrary String or Enum backed checkboxes. Spring will send "false" to a boolean or String for an unchecked checkbox. Yet when checked, users can send any String they want, not just "true". In many cases I have to provide a checkbox UI for an Enum of ENABLED, DISABLED, DELETED. Many clients require database deletes to be handled with this status. Users of screens can ENABLE or DISABLE, but never see the DELETED status records on these pages.
   (In the attachment, see processStringCheckboxes method of BaseFormController.)
