JFinal验证器

JFinal挺好用，但是岁数大了有些东西老是记不住，备份一下

public class BlogValidator extends Validator {
    protected void validate(Controller controller) {
        validateRequiredString("blog.title", "titleMsg", "请输入Blog标题!");
        validateRequiredString("blog.content", "contentMsg", "请输入Blog内容!");
    }
	
    protected void handleError(Controller controller) {
        controller.keepModel(Blog.class);
    }
}
