In Spring MVC For validation use @Pattern annotation like this:
@Pattern(regexp = "???", message = "#i18n{obligatoire}")
@NotEmpty
private String stringTest;
I want just exclude & character. @Pattern(regexp = "^&") it's correct ?
^[^&]*?$ is regex you are looking for.
@Pattern(regexp = "^[^&]*$")
@NotEmpty
private String stringTest;
Explanation:
[^&] captures any character that is not &[^&]* captures all characters that are not &^[^&]*$ captures all characters on the line (^ is the beggining of the line, $ is the end of the line) that are not &
