Multiple Regex @Pattern's for 1 Field?

Question

I was attempted to apply multiple @Pattern annotations to a single field:

@Pattern(regexp = "(?=.*[0-9])", message = "Password must contain one digit.") @Pattern(regexp = "(?=.*[a-z])", message = "Password must contain one lowercase letter.") @Pattern(regexp = "(?=.*[A-Z])", message = "Password must contain one uppercase letter.") @Pattern(regexp = "(?=\S+$)", message = "Password must contain no whitespace.") private String password; 

However, I cannot do this. I want individual messages per violated regex constraint on the password field. Is this possible?

My alternative is to use JSF 2.0 f:validatorRegex tags.

You can use the inner @List annotation of @Pattern:

@Pattern.List({     @Pattern(regexp = "(?=.*[0-9])", message = "Password must contain one digit."),     @Pattern(regexp = "(?=.*[a-z])", message = "Password must contain one lowercase letter."),     @Pattern(regexp = "(?=.*[A-Z])", message = "Password must contain one uppercase letter."),     @Pattern(regexp = "(?=\\S+$)", message = "Password must contain no whitespace.") }) private String password;

Gunnar's solution won't work for me... '.+' in his regexp seem to be missing. However, i'm using Michal's patternList and it works like a charm for me. (Play 2.3.x / Ebean-ORM)

@Pattern.List({         @Pattern(regexp = "(?=.*[0-9]).+", message = "Password must contain one digit."),         @Pattern(regexp = "(?=.*[a-z]).+", message = "Password must contain one lowercase letter."),         @Pattern(regexp = "(?=.*[A-Z]).+", message = "Password must contain one upper letter."),         @Pattern(regexp = "(?=.*[!@#$%^&*+=?-_()/\"\\.,<>~`;:]).+", message ="Password must contain one special character."),         @Pattern(regexp = "(?=\\S+$).+", message = "Password must contain no whitespace.") }) @Constraints.Required() public String password1;
