spring boot redis缓存JedisPool使用
添加依赖pom.xml中添加如下依赖
<!-- Spring Boot Redis -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-redis</artifactId>
</dependency>

测试
注入
@Autowired
JedisPool jedisPool;
测试
String uuid = UUID.randomUUID().toString();
logger.info("jedisPool uuid : " + uuid);
try (Jedis jedis = jedisPool.getResource()) {
jedis.setex(uuid, 1000, user.getUsername());
}
