spring boot中使用spring cache

原因

项目原来越慢，为了提升效率加入spring cache 初步想法把数据库的压力减轻一点。

引入

pom 中加入：

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

项目用的是properties
加入配置

spring.redis.database=4
spring.redis.host=127.0.0.1
spring.redis.port=6380
spring.redis.password=xxxxxxx
spring.redis.pool.max-active=8
spring.redis.pool.max-wait=-1
spring.redis.pool.max-idle=8
spring.redis.pool.min-idle=0
spring.redis.timeout=0
spring.cache.redis.time-to-live=1800000
