Method Detail

buildErrorMessage

protected void buildErrorMessage(java.lang.String fieldName,
                                 @Nonnull
                                 javax.validation.ConstraintValidatorContext context,
                                 java.lang.Object... args)

Creates custom error message.

Message template is taken from validation context. In general it is the one specified in C.message field. Strings {string.resource.id} treated as string key of localized string resource. Current add locale is used to resolve value.
To have such string as it is, double the surrounding curly brackets: {{not.a.resource{0}}} will be show as {not.a.resource<value_of_first_arg>}

The resulting string is then passed to MessageFormat.format(String, Object...) along with args only if any args provided.

Please pay attention to syntax inconsistency between parametrized and non-parametrized lines: It''s a parametrized line with arg ''{0}'' but It'a a non-parametrized line

Parameters:

fieldName - name of field where the error occurred

context - validation context

args - optional message arguments

Throws:

java.lang.IllegalStateException - if the instance has not been initialized by Spring (see BasicBundleRuleValidator.initialize(Annotation) as an example of initialization)
