  • annotation-based bean validation error messages

    Hi,

    I'm investigating an annotation-based approach to command bean validation using spring modules. In the tutorial, the following command bean (getters and setters omitted) is used:

    Code:
    public final class UserMessage {  
           
      @NotBlank  
      @Length(max = 80)  
      private String name;  
           
      @NotBlank  
      @Email  
      @Length(max = 80)  
      private String email;  
           
      @NotBlank  
      @Length(max = 4000)  
      private String text;  
    }
    And the following are (some of the) configured error messages:

    Code:
    UserMessage.email[not.blank]=Please enter your e-mail address.  
    UserMessage.email[email]=Please enter a valid e-mail address.  
    UserMessage.email[length]=Please enter no more than {2} characters.
    The net effect is that if the rule about e-mail length is not observed, the message produced is:

    "Please enter no more than 80 characters"

    Where are the values substituted for each of the {} placeholders documented? In other words, how can I find out what will be substituted for {0}, {1},...,{N} for a particular validation rule?

    Thanks in advance,
    DM

    Hello domurtag,

    Those placeholder are filled when you create Error instances using one of the reject methods that has "errorArgs"

    Eg see http://static.springframework.org/sp...va.lang.Object[],%20java.lang.String)
