+可以看到结构已经清晰了不少，已经按照四个主要步骤将功能分割开，原本臃肿的`PromotionMail`类现在只剩下3个方法，出去`main`方法，就只剩下处理发送邮件逻辑的`PromotionMail`和`sendEMails`
+```java
+public class PromotionMail {
+
+	UserService userService = new UserService();
+	ProductService productService = new ProductService();
+
+	public static void main(String[] args) throws Exception {
+		File file = new File("src/main/java/com/coderising/ood/srp_restructure_1/product_promotion.txt");
+		boolean emailDebug = false;
+		PromotionMail pe = new PromotionMail(file, emailDebug);
+	}
+
+	public PromotionMail(File file, boolean mailDebug) throws Exception {
+		// 略
+	}
+
+	protected void sendEMails(boolean debug, MailServiceConfiguration configuration, List<Product> plist){
+		// 略
+	}
+}

+至此，基本实现了单一指责原则(自认为（´＿｀）)
