SpringBoot缓存技术整合SpringData Redis

首先说明一下,这里使用的是Springboot2.2.6.RELEASE版本,由于Springboot迭代很快,所以要注意版本问题。

1、SpringData Redis是属于SpringData下的一个模块。作用就是简化对于redis的操作。SpringData JPA为了简化对数据库的操作。修改pom文件添加SpringData Redis的坐标。

编写SpringData Redis的配置类,替代了之前的配置文件。

编写测试代码,测试整合环境。

 1 package com.bie.springboot;

 3 import org.junit.jupiter.api.Test;
 4 import org.junit.runner.RunWith;
 5 import org.springframework.beans.factory.annotation.Autowired;
 6 import org.springframework.boot.test.context.SpringBootTest;
 7 import org.springframework.data.redis.core.RedisTemplate;
 8 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
 9 
10 @RunWith(SpringJUnit4ClassRunner.class)
11 @SpringBootTest(classes = SpringdataRedisApplication.class)
12 class SpringdataRedisApplicationTests {
13 
14     @Autowired
15     private RedisTemplate redisTemplate;
16 
17     /*** 添加一个字符串 */
18     @Test
19     public void testSet() {
20         this.redisTemplate.opsForValue().set("key", "我想要学好springboot");
21     }
22 
23     /*** 获取一个字符串 */
24     @Test
25     public void testGet() {
26         String value = (String) this.redisTemplate.opsForValue().get("key");
27         System.out.println(value);
28     }
29

是Jedis版本问题:将Jedis改为 3.0.0版本或者2.10.1版本后即可解决。我是将Jedis2.9.0版本改为了Jedis3.0.0版本解决了问题。

3     redis.clients
4     jedis
5     3.0.0

提取redis的配置信息,在application.properties配置文件中新增配置信息。 

 1 # 最大空闲数,最后缀必须固定
 2 spring.redis.jedis.pool.max-idle=10
 3 # 最小空闲数,连接池中最小空闲连接
 4 spring.redis.jedis.pool.min-idle=10
 5 # 最大链接数,连接池最大连接数(使用负值表示没有限制)
 6 spring.redis.jedis.pool.max-active=8
 7 # 当池内没有可用的连接时,最大等待时间
 8 spring.redis.jedis.pool.max-wait=-1ms
 9 
10 
11 
12 # 设置redis的主机
13 spring.redis.hostName=192.168.110.140
14 # 设置redis的端口号
15 spring.redis.port=6379
16 # 设置操作第一个数据库
17 spring.redis.database=0

修改配置类,配置属性在application.properties进行设置。

SpringBoot缓存技术整合SpringData Redis_第1张图片

Spring Boot整合Spring Data Redis,来进行存取JSON格式Java对象。实体类直接序列化存储比实体类转换为json格式存储要大,所以也可以选择以json格式进行存储实体类对象,以 JSON 格式存储实体对象。
