将 Azure Cache for Redis 连接到 Azure Spring Apps 中的应用程序

1. 在项目的 pom.xml 文件中，添加以下依赖项：

   <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-data-redis-reactive</artifactId>
   </dependency>
   

2. 从 application.properties 文件中，删除所有 spring.redis.* 属性

3. 使用 az spring app update 更新当前部署，或者使用 az spring app deployment create 创建新的部署。

以下 Terraform 脚本演示如何使用 Azure Cache for Redis 设置 Azure Spring Apps 应用。
