[Java高并发秒杀API之业务分析与DAO层 ](https://www.imooc.com/learn/630) 5 | 2. [Java高并发秒杀API之Service层](https://www.imooc.com/learn/631) 6 | 3. [Java高并发秒杀API之web层](https://www.imooc.com/learn/630) 7 | 4. [Java高并发秒杀API之高并发优化](https://www.imooc.com/learn/632) 8 | 5. [Java秒杀系统方案优化 高性能高并发实战](https://coding.imooc.com/class/168.html) 9 | 10 | #### 秒杀功能 11 | - 秒杀接口暴露 12 | - 执行秒杀 13 | - 相关查询 14 | 15 | #### 代码开发阶段 16 | - [Dao设计编码：接口设计+SQL编写](https://github.com/colg-cloud/seckill/tree/master/src/main/java/cn/colg/dao) 17 | - [Service设计编码：业务逻辑实现](https://github.com/colg-cloud/seckill/tree/master/src/main/java/cn/colg/service) 18 | - [Web设计编码：前端业务交互](https://github.com/colg-cloud/seckill/tree/master/src/main/java/cn/colg/web) 19 | 20 | --- 21 | 22 | #### 技术总结 23 | ##### 联合主键，避免重复秒杀 24 | ``` 25 | -- 秒杀成功明细表 26 | -- 联合主键 27 | PRIMARY KEY (seckill_id, user_phone), 28 | ``` 29 | 在这里使用**秒杀商品id+用户手机号**作为秒杀成功的一个联合主键。当用户使用该手机秒杀同一件商品时从数据库层面来说是不允许的。 30 | 可以从单元测试的日志查看： 31 | ``` 32 | private static final Log log = LogFactory.get(); 33 | 34 | @Test 35 | public void testInsertSuccessKilled() { 36 | String seckillId = "c18c169938c311e89fa754ee75c6aeb0"; 37 | String userPhone = "18701012345"; 38 | int insertCount = successKilledMapper.insertSuccessKilled(seckillId, userPhone); 39 | log.info("insertCount： {}", insertCount); 40 | } 41 | ``` 42 | 执行结果： 43 | 1. 第一次：`INFO cn.colg.dao.SuccessKilledMapperTest - insertCount： 1` 表示插入成功 44 | 2. 第二次：`INFO cn.colg.dao.SuccessKilledMapperTest - insertCount： 0` 表示插入失败 45 | 46 | ##### 使用注解控制事务方法的优点 47 | ``` 48 | 49 | 50 | 51 | @Transactional(propagation=Propagation.REQUIRED) ：如果有事务, 那么加入事务, 没有的话新建一个(默认情况下) 52 | @Transactional(propagation=Propagation.NOT_SUPPORTED) ：容器不为这个方法开启事务 53 | @Transactional(propagation=Propagation.REQUIRES_NEW) ：不管是否存在事务,都创建一个新的事务,原来的挂起,新的执行完毕,继续执行老的事务 54 | @Transactional(propagation=Propagation.MANDATORY) ：必须在一个已有的事务中执行,否则抛出异常 55 | @Transactional(propagation=Propagation.NEVER) ：必须在一个没有的事务中执行,否则抛出异常(与Propagation.MANDATORY相反) 56 | @Transactional(propagation=Propagation.SUPPORTS) ：如果其他bean调用这个方法,在其他bean中声明事务,那就用事务.如果其他bean没有声明事务,那就不用事务. 57 | @Transactional(timeout=30) //默认是30秒 58 | ``` 59 | 1. 开发团队达成一致的风格，明确标注事务方法的编程风格。 60 | 2. 保证事务方法的执行时间尽可能短，不要穿插其他网络操作RPC/HTTP请求或者剥离到事务方法外部。 61 | 3. 不是所有的方法都需要事务，如：只有一条修改操作，只读操作不需要事务控制 62 | 63 | ###### 错误处理 64 | [According to TLD or attribute directive in tag file, attribute value does not accept any expressions](https://blog.csdn.net/jasper_success/article/details/6693434) 65 | ``` 66 | <%@ taglib uri="http://java.sun.com/jstl/core" prefix="c"%> 改为 <%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c"%> 67 | <%@ taglib uri="http://java.sun.com/jstl/fmt" prefix="fmt"%> 改为 <%@ taglib uri="http://java.sun.com/jstl/fmt_rt" prefix="fmt"%> 68 | ``` 69 | 70 | #### 使用说明 71 | 1. 首先从github上把项目传到本地，可以直接下载项目的压缩包，点击Clone or download,然后Download Zip。也可以通过git，使用git clone https://github.com/colg-cloud/seckill 命令，把项目克隆到本地 72 | 2. 然后修改数据库连接信息，在resources目录下jdbc.properties配置文件中修改 73 | 3. 使用maven tomcat7插件启动项目， 进入项目目录，打开cmd输入：`mvn tomcat7:run` 74 | -------------------------------------------------------------------------------- /SQL/schema.sql: -------------------------------------------------------------------------------- 1 | -- 数据库初始化脚本 2 | 3 | -- 创建数据库 4 | CREATE DATABASE seckill;
