一、引入依赖
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId><version>2.4.4</version></dependency>
二、后台代码：
spring.redis.database=0 spring.redis.host=192.168.1.xxx spring.redis.port=8099 spring.redis.jedis.pool.max-active=8 spring.redis.jedis.pool.max-wait=-1ms spring.redis.jedis.pool.max-idle=8 spring.redis.jedis.pool.min-idle=0 spring.redis.timeout=0
@Controller
@Api(tags = "书本数据接口")
@EnableCaching//开启缓存public class BookController {
｝ @Cacheable(value = "book_id")//使用缓存 @Overridepublic Book getBookById(Integer id) {
System.out.println("从数据库中查询。。。。。");return bookMapper.getBookById(id);
}
