基于Springboot+Redis秒杀系统 demo

基于SpringBoot+Redis的商品秒杀系统的Demo。这个例子将展示如何防止商品超卖。

1. 首先创建项目依赖(pom.xml):

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
    </dependency>
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.2.0</version>
    </dependency>
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>
</dependencies>

2. 创建商品实体类(Product.java):

@Data
public class Product {
   
   
    private Long id;
    private String name;
    private Integer stock;
    private BigDecimal price;
}

3. 创建订单实体类(Order.java):

@Data
public class Order {
   
   
    private Long id;
    private Long productId;
    private Long userId;
    private
