1、添加pom依赖：
注意：建议不要使用spring-boot-starter-redis，此包Jun, 2017后已停止维护
示例：
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-cache</artifactId>
<version>${spring-boot.version}</version>
</dependency>
2、redis配置：
示例：
spring:
redis:
database: 1
jedis:
pool:
max-active: 8
max-wait: -1
max-idle: 8
min-idle: 0
timeout: 10000
cluster: #如果是redis集群使用此配置
nodes:
- 127.0.0.1:9001
- 127.0.0.1:9002
- 127.0.0.1:9003
host: 172.16.0.7 #如果是单机redis使用一下配置
port: 6379
password: 123
3、redis使用：
（1）spring-boot已经定义了redisTemplate、stringRedisTemplate两个bean，可以直接使用也可自行定义
package org.springframework.boot.autoconfigure.data.redis;
import java.net.UnknownHostException;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Import;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisOperations;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
/**

*/
@Configuration
@ConditionalOnClass(RedisOperations.class)
@EnableConfigurationProperties(RedisProperties.class)
@Import({ LettuceConnectionConfiguration.class, JedisConnectionConfiguration.class })
public class RedisAutoConfiguration {
@Bean
@ConditionalOnMissingBean(name = "redisTemplate")
public RedisTemplate<Object, Object> redisTemplate(
RedisConnectionFactory redisConnectionFactory) throws UnknownHostException {
RedisTemplate<Object, Object> template = new RedisTemplate<>();
template.setConnectionFactory(redisConnectionFactory);
return template;
}
@Bean
@ConditionalOnMissingBean
public StringRedisTemplate stringRedisTemplate(
RedisConnectionFactory redisConnectionFactory) throws UnknownHostException {
StringRedisTemplate template = new StringRedisTemplate();
template.setConnectionFactory(redisConnectionFactory);
return template;
}
}
（2）此处自行定义了一个泛型为<String,Object>的redisTemplate（个人感觉更实用），示例如下：
package com.longc.core.config;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.data.redis.RedisProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
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.RedisOperations;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
/**
* redis配置
* Created by log.chang on 2019/6/26.
*/
@Configuration
@ConditionalOnClass(RedisOperations.class)
@EnableConfigurationProperties(RedisProperties.class)
public class RedisConfig {
/**
* 定义redisTemplate
* 如果在配置文件中定义配置如下：
* <bean id="jedisConnectionFactory"
* class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory">

* <property name="port" value="${redis.port}"/>

* <property name="timeBetweenEvictionRunsMillis" value="${redis.pool.timeBetweenEvictionRunsMillis}"/>
* <property name="minEvictableIdleTimeMillis" value="${redis.pool.minEvictableIdleTimeMillis}"/>
* <property name="testOnBorrow" value="${redis.pool.testOnBorrow}"/>
* </bean>
* </property>
* </bean>
* <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
* <property name="connectionFactory" ref="jedisConnectionFactory"/>
* <property name="keySerializer">
* <bean class="org.springframework.data.redis.serializer.StringRedisSerializer"/>
* </property>
* <property name="valueSerializer">

* </property>
* <property name="hashValueSerializer">
* <bean class="org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer"/>
* </property>
* </bean>
*/
@Bean
@SuppressWarnings("all")
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
template.setConnectionFactory(factory);
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
ObjectMapper om = new ObjectMapper();
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(om);
StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
// key采用String的序列化方式
template.setKeySerializer(stringRedisSerializer);
// hash的key也采用String的序列化方式
template.setHashKeySerializer(stringRedisSerializer);
// value序列化方式采用jackson
template.setValueSerializer(jackson2JsonRedisSerializer);
// hash的value序列化方式采用jackson
template.setHashValueSerializer(jackson2JsonRedisSerializer);
template.afterPropertiesSet();
return template;
}
}
（3）封装redis工具类
可以参考 https://www.cnblogs.com/zeng1994/p/03303c805731afc9aa9c60dbbd32a323.html 还是挺全的
