md，手画的图手机拍照上传后太大，难以查看，推荐画图（推荐 PPT、Keynote）； 29 | 6. 提交记录最好要标明明确的含义（比如第几题作业）。 30 | 31 | 32 | ## 操作步骤 33 | 34 | 35 | ### 第八周-作业1. （选做） 36 |

撮合的业务特点, 练习 Producer + Consuer 的用法： 7 | - 定序要求: 数据有序并且不丢失 8 | - 撮合要求: 可重放, 顺序消费, 消息仅处理一次 9 | 10 | ### 消息格式 11 | 消息的内容格式为：// 见本仓库的代码 12 | ``` 13 | public class Order{ 14 | private Long id； 15 | private Long ts; 16 | private String symbol; 17 | private Double price; 18 | 19 | // 省略setter getter... 20 | } 21 | ``` 22 | 23 | ### 作业要求 24 | 1. `Producer`接口应该有序发送消息 25 | 2. `Producer`接口应该不丢失消息 26 | 3. `Consumer`接口应该顺序消费消息 27 | 4. `Consumer`接口应该支持从offset重新接收消息 28 | 5. `Consumer`接口应该支持消息的幂等处理，即根据id去重 29 | 6. 设计挑战：尝试接口对外暴露的使用方式，完全屏蔽了kafka的原生接口和类 30 | 7. 编码挑战：实现程序都正确，而且写了单元测试 31 | 32 | ### 提交方式：过程分（3分） 33 | 1. 设计一个 `io.kimmking.javacourse.自己姓名拼音.Producer` 接口，需满足以上要求，并尝试实现 34 | 2. 设计一个 `io.kimmking.javacourse.自己姓名拼音.Consumer` 接口，需满足以上要求，并尝试实现 35 | 3. 提交以上代码，并提交一个Pull Request到本仓库，在钉钉群回复已经完成，1分 36 | 37
