springboot集成 Redis快速入门demo

一、准备redis环境

这里用docker-compose来搭建Redis测试环境，采用单机模式，具体配置如下：

docker-compose-redis.yml

version: '3'
services:redis:image: registry.cn-hangzhou.aliyuncs.com/zhengqing/redis:6.0.8                    # image 'redis:6.0.8'container_name: redis                                                             # 容器名为'redis'restart: unless-stopped                                                                   # 指定容器退出后的重启策略为始终重启，但是不考虑在Docker守护进程启动时就已经停止了的容器command: redis-server /etc/redis/redis.conf --requirepass 123456 --appendonly no # 启动redis服务并添加密码为：123456,默认不开启redis-aof方式持久化配置
#    command: redis-server --requirepass 123456 --appendonly yes # 启动redis服务并添加密码为：123456,并开启redis持久化配置environment:                        # 设置环境变量,相当于docker run命令中的-eTZ: Asia/ShanghaiLANG: en_US.UTF-8volumes:                            # 数据卷挂载路径设置,将本机目录映射到容器目录- "./redis/data:/data"- "./redis/config/redis.conf:/etc/redis/redis.conf"  # `redis.conf`文件内容`http://download.redis.io/redis-stable/redis.conf`ports:                              # 映射端口- "6379:6379"

二、搭建测试工程

1.pom.xml

<!--redis client-->
<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency><groupId>org.apache.commons</groupId><artifactId>commons-pool2</artifactId><version>2.9.0</version>
</dependency>

2.RedisConfig.java

package com.et59.redis.config;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;/*** redisTemplate  config*/
@Configuration
public class RedisConfig {/*** redis template.** @param factory factory* @return RedisTemplate*/@Beanpublic RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {RedisTemplate<String, Object> template = new RedisTemplate<>();template.setConnectionFactory(factory);template.setKeySerializer(new StringRedisSerializer());template.setHashKeySerializer(new StringRedisSerializer());template.setValueSerializer(new GenericJackson2JsonRedisSerializer());template.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());template.afterPropertiesSet();return template;}
}

3.application.yaml

server:port: 8088
spring:redis:database: 0host: 127.0.0.1port: 6379password: 123456lettuce:pool:min-idle: 0max-active: 8max-idle: 8max-wait: -1msconnect-timeout: 30000ms

4.验证服务是否可用

package com.et.redis;
import com.et59.redis.DemoApplication;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.test.context.junit4.SpringRunner;@RunWith(SpringRunner.class)
@SpringBootTest(classes = DemoApplication.class)
public class RedisTests {private Logger log = LoggerFactory.getLogger(getClass());@Autowiredprivate RedisTemplate redisTemplate;@Testpublic void save() {redisTemplate.opsForValue().set("test","this is a test");System.out.println(redisTemplate.opsForValue().get("test"));}}

结果预期一样输出
