Validation

Spring Shell 与 Bean Validation API 相集成,支持命令参数的自动和自文档式的限制。

将遵守命令参数上的注释和方法级别的注释,并在执行命令前触发验证。考虑以下命令:

	@ShellMethod("Change password.")
	public String changePassword(@Size(min = 8, max = 40) String password) {
		return "Password successfully set to " + password;
	}

从前面的示例中,您将免费获得以下行为:

shell:>change-password hello
The following constraints were not met:
	--password string : size must be between 8 and 40 (You passed 'hello')
