+		// (2) DownloadListener, 由于是多线程下载， 调用这个类的客户端不知道什么时候结束，所以你需要实现当所有
+		//     线程都执行完以后， 调用listener的notifiedFinished方法， 这样客户端就能收到通知。

+# 第一次OOD练习 #
+
+## 需求 ##
+### 原项目已经实现根据产品列表文件发送促销Mail，需求一直在变化，比如通过数据库获取促销产品或者促销活动改为到货通知，抢购等；为了应变各种变化，需重构代码。 ###
+## 需求分析 ##
+需求可变因素:</br>
+
+1. 促销产品列表文件可能会变更，或者变更获取方式（如通过数据库获取）
+2. 促销活动会根据运营情况变更
+## 重构方案 ##
+1. 提取GetProductsFunction，SendMailFunction接口
+2. 添加Notice抽象类，针对接口添加getProducts,sendMai方法 -------各类通知（降价促销，抢购活动，到货通知等等）
+3. 添加Mail,Product,User实体类
+4. Mail初始化设置smtpHost,alSmtpHost,fromAddress参数，添加sendMail功能
+5. Product添加getSubscribers功能
+6. 添加GetProductsFunction，SendMailFunction接口实现类
+7. 添加PricePromotion继承Promotion，实现降价促销功能，实例化GetProductsFunction，SendMailFunction接口    
+8. 主函数调用sendMail方法
+
+## 重构后 ##
+重构后项目，可以根据不同运营方案，添加GetProductsFunction，SendMailFunction接口实现类及Notice子类，向订阅者发送通告
+
+

1、增加FileUtil类，负责读取txt中降价产品。
2、增加Product类，包含id和desc属性。
3、重构MailUtil类，负责配置邮件服务器和发送邮件。
4、增加UserService类，负责获得关注降价产品的用户列表。
5、重构PromotionMail类，只负责设置邮件主题、正文、收件人列表，以及发送邮件。

- * 用数组实现循环队列 - 杜绝“假上溢”
- * 在入队和出队的操作中，头尾指针只增加不减小，致使被删除元素的空间永远无法重新利用。

- * 因此，尽管队列中实际的元素个数远远小于向量空间的规模，但也可能由于尾指针巳超出向量空间的上界而不能做入队操作。
- * 为充分利用向量空间。克服上述假上溢现象的方法是将向量空间想象为一个首尾相接的圆环，并称这种向量为循环队列。
- * 在循环队列中进行出队、入队操作时，头尾指针仍要加1，朝前移动。

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1、增加了LogType和LogMethod两个接口。
2、Logger类包含了LogType和LogMethod两个属性。
3、Logger类的log()方法直接调用LogType实例对象的getMsg()方法和LogMethod实例对象的send()方法。

+整个发送的流程主要是以下步骤
+1. 从配置文件中读取，生成要发送的产品信息。
+2. 设置邮件发送需要的SMTPHOST,ALTSMTPHOST,FROMADDRESS
+3. 查询出需要发送的用户列表
+4. 设置发送邮件需要的 信息，从用户列表中读取要发送去的地址，用产品信息拼凑出Message
+5. 发送邮件。
+其实Promotion就是一个job，衔接各个Handler，不自己做逻辑，完成发信的一个任务。
+
+所以我理解首先可以独立出来的一堆职责就是邮件发送的类，它能够被初始化，然后接受参数发送邮件。
+
+所以首先抽取出的职责就是和邮件发送相关的职责。EmailHandler。
+smtphost和altSmtpHost是定死的，应该设定成系统初始化时就设定好，至于From address在发送企业推送邮件时，也是统一的，也考虑封装在EmailHandler内部。
+在初始化一个EmailHandler时，即完成了邮件系统的相关设置。
+然后将发信的逻辑封装在EmailHandler内部。
+然后在PromotionMail中移除邮件系统相关的配置，引入EmailHandler。
+现在所有和发送相关以及邮件系统初始化的逻辑，全部移动到了EmailHandler内部。
+```java
+public PromotionMail(File file, boolean mailDebug) throws Exception {
+		// 读文件，获得要推送的商品信息
+		readFile(file);
+		// 查询用户
+		setLoadQuery();
+		// 初始化邮件发送Handler
+		EmailHandler emailHandler = new EmailHandler();
+		// 对私有函数增加一个参数。
+		sendEMails(mailDebug, loadMailingList(), emailHandler);
+	}
+```
+
+ok，接下来，邮件发送需要的主体信息是来自外部的，但它可以是一个纯数据类，存放着发送者，主题，message，一个pojo类，sendEMails应该只需要接受pojo的list，然后直接调emailHandler的发送函数即可，而不需要在里面还要进行取值的操作。
+```java
+		configureEMail((HashMap) iter.next());
+	    boolean result = emailHandler.sendMail(toAddress, subject, message, debug);
+```
+一个简单的pojo类，emailHandler应该接受这个作为参数，修改代码如下
+```java
+  private String fromAddress;
+    private String toAddress;
+    private String subject;
+    private String message;
+```
+新的发送邮件的函数
+```java
+private void sendEMails(boolean debug, List<EmailEntity> emailEntities, EmailHandler emailHandler)
+			throws IOException {
+
+		System.out.println("开始发送邮件");
+		if (CollectionUtils.isNotEmpty(emailEntities)) {
+			for (EmailEntity emailEntity : emailEntities) {
+				boolean result = emailHandler.sendMail(emailEntity, debug);
+				System.out.println("发送邮件结果: " + result);
+			}
+		} else {
+			System.out.println("没有邮件发送");
+		}
+	}
+```
+emailHandler直接和emailEntity交互。
+接下来就是说我们怎么去构造emailEntities这个list了。
+然后这个商品信息的文件读取出来是一个list，首先对原有的读文件函数进行改动，用一个pojo类去代表商品的信息。同样的，用户的返回我们也用一个pojo类存储，因为这些东西以后的加字段可能是比较高的，通过一个统一的实体来管理会比较好。
+然后在job类里少用this，通过传参的方式，首先改变查询用户的函数，传入参数查询语句，返回的是user的list。
+分别构造出用来查询商品和用来处理用户的私有方法，准备下一步的重构。
+将查询商品相关的处理，封装到ProductHandler内部，只对外暴露获得商品列表的接口。
+```java
+// 查询商品
+List<Product> products = new ProductHandler().fetchProducts();
+```
+用户是根据订阅了商品的来查的，所以处理用户的UserHandler接受一个sql语句查询，和商品之间解耦。
+
+最终总结就是通过三个处理器负责商品，用户，邮件的处理，原有的PromotionMail则相当于是衔接各个处理器的job，具体的业务逻辑放在各个handler内部完成处理。
+
+重构完毕。

-# 第一次OOD练习 #
-
-## 需求 ##
-### 原项目已经实现根据产品列表文件发送促销Mail，需求一直在变化，比如通过数据库获取促销产品或者促销活动改为到货通知，抢购等；为了应变各种变化，需重构代码。 ###
-## 需求分析 ##
-需求可变因素:</br>
-
-1. 促销产品列表文件可能会变更，或者变更获取方式（如通过数据库获取）
-2. 促销活动会根据运营情况变更
-## 重构方案 ##
-1. 提取GetProductsFunction，SendMailFunction接口
-2. 添加Notice抽象类，针对接口添加getProducts,sendMai方法 -------各类通知（降价促销，抢购活动，到货通知等等）
-3. 添加Mail,Product,User实体类
-4. Mail初始化设置smtpHost,alSmtpHost,fromAddress参数，添加sendMail功能
-5. Product添加getSubscribers功能
-6. 添加GetProductsFunction，SendMailFunction接口实现类
-7. 添加PricePromotion继承Promotion，实现降价促销功能，实例化GetProductsFunction，SendMailFunction接口    
-8. 主函数调用sendMail方法
-
-## 重构后 ##
-重构后项目，可以根据不同运营方案，添加GetProductsFunction，SendMailFunction接口实现类及Notice子类，向订阅者发送通告

+# 第一次OOD练习 #
+
+## 需求 ##
+### 原项目已经实现根据产品列表文件发送促销Mail，需求一直在变化，比如通过数据库获取促销产品或者促销活动改为到货通知，抢购等；为了应变各种变化，需重构代码。 ###
+## 需求分析 ##
+需求可变因素:</br>
+
+1. 促销产品列表文件可能会变更，或者变更获取方式（如通过数据库获取）
+2. 促销活动会根据运营情况变更
+## 重构方案 ##
+1. 提取GetProductsFunction，SendMailFunction接口
+2. 添加Notice抽象类，针对接口添加getProducts,sendMai方法 -------各类通知（降价促销，抢购活动，到货通知等等）
+3. 添加Mail,Product,User实体类
+4. Mail初始化设置smtpHost,alSmtpHost,fromAddress参数，添加sendMail功能
+5. Product添加getSubscribers功能
+6. 添加GetProductsFunction，SendMailFunction接口实现类
+7. 添加PricePromotion继承Promotion，实现降价促销功能，实例化GetProductsFunction，SendMailFunction接口    
+8. 主函数调用sendMail方法
+
+## 重构后 ##
+重构后项目，可以根据不同运营方案，添加GetProductsFunction，SendMailFunction接口实现类及Notice子类，向订阅者发送通告
+
