本教程主要详细讲解Spring Data Redis,它向Redis提供Spring Data平台的抽象.
Redis由基于key/value库的数据结构存数，以持久保存数据，并可用作数据库，缓存，消息代理等。
基础环境
| 技术 | 版本 |
|---|---|
| Java | 1.8+ |
| SpringBoot | 2.x.x |
| DataJPA | 2.x.x |
| Jedis | 2.9.x |
创建项目
- 初始化项目
mvn archetype:generate -DgroupId=com.edurt.sli.slidr -DartifactId=spring-learn-integration-datajpa-redis -DarchetypeArtifactId=maven-archetype-quickstart -Dversion=1.0.0 -DinteractiveMode=false- 修改pom.xml增加redis的支持

- 一个简单的应用类

- 在resources资源目录下创建一个application.properties的配置文件,内容如下
spring.redis.host=localhostspring.redis.port=6379spring.redis.database=0spring.redis.jedis.pool.max-active=8spring.redis.jedis.pool.max-wait=1msspring.redis.lettuce.pool.max-active=8spring.redis.jedis.pool.min-idle=0操作Redis数据
- 在
/src/main/java/com/edurt/sli/slidr目录下创建model目录,并在该目录下新建RedisModel文件

@Id注解的属性和被命名为id的属性会被当作标识属性
- 在

- 打包数据
mvn clean package -Dmaven.test.skip=true -X运行打包后的文件即可
