For the latest stable version, please use Spring Shell 3.3.3! |
Validation
Spring Shell integrates with the Bean Validation API to support automatic and self-documenting constraints on command parameters.
Annotations found on command parameters and annotations at the method level are honored and trigger validation prior to the command executing. Consider the following command:
@ShellMethod("Change password.")
public String changePassword(@Size(min = 8, max = 40) String password) {
return "Password successfully set to " + password;
}
From the preceding example, you get the following behavior for free:
shell:>change-password hello The following constraints were not met: --password string : size must be between 8 and 40 (You passed 'hello')
